Description

Technical Field

[0001] The invention relates to coffee, in particular to a carbon-blocking and fat-burning coffee composition and a preparation process and application thereof, belonging to the technical field of coffee. Background Art

[0002] With the acceleration of modern life and changes in dietary structure, obesity has become a global health challenge. More and more consumers are beginning to pay attention to and seek health foods that can effectively assist in weight loss. Among them, coffee drinks are very popular because of their unique taste and refreshing effect. However, traditional coffee products on the market often contain high sugar content, which not only has a poor fat-reducing effect, but may also have a negative impact on health.

[0003] In view of the above market situation and consumer demand, it is particularly important to develop a coffee composition that can block carbon and burn fat. If the content of carbon-blocking and fat-burning substances in coffee can be increased, it can not only promote emotional excitement and agility in thinking for drinkers, but also promote fat burning and reduce weight, which is especially suitable for coffee lovers who need to lose weight.

[0004] Therefore, the development of a coffee composition that blocks carbon and burns fat not only meets the urgent needs of the current market, but also has important commercial value and social significance. Summary of the invention

[0005] In view of the above existing technical problems, the present invention provides a coffee composition for blocking carbon and burning fat, and its preparation process and application, so as to achieve the weight loss effect of blocking carbon and promoting fat burning.

[0006] To achieve the above technical objectives, firstly, the present invention provides a coffee composition for resisting carbon and burning fat, comprising the following raw materials and their weight portions: 80-85 parts of freeze-dried black coffee, 10-15 parts of green coffee extract, 1-3 parts of white kidney bean extract, and 1-2 parts of L-carnitine.

[0007] In the above technical solution, various raw materials achieve the weight loss effect through different mechanisms, which are specifically introduced as follows.

[0008] (1) As a non-additive, low-calorie drink, black coffee does have unique advantages in assisting weight loss. The caffeine it contains can not only effectively suppress appetite and help control food intake, but also promote nerve excitement and increase physical vitality. This feature makes black coffee the drink of choice for many people who want to lose weight.

[0009] Specifically, the diuretic effect of caffeine can speed up the excretion of water in the body, which helps to lose weight and promote the body's metabolism. At the same time, caffeine can also increase the metabolism of non-oxidative fatty acids, which means that the body can more efficiently use fat as an energy source, thereby speeding up the decomposition and consumption of fat.

[0010] In addition, caffeine can increase resting energy expenditure (REE) and resting metabolic rate (RMR). These two indicators are important parameters for measuring the energy consumed by the body when it is at rest. By increasing these two indicators, caffeine allows the body to continue burning calories even when it is at rest, further promoting the weight loss effect.

[0011] It is worth mentioning that caffeine can also reduce the perception of physical exertion. This means that when doing the same intensity of exercise, people who drink black coffee may feel more relaxed and thus more likely to stick to it. This additional effect of burning body calories undoubtedly provides strong support for weight loss.

[0012] (2) As an evergreen shrub or small tree of the Rubiaceae family, green coffee not only attracts people's attention with its unique growth form and beautiful flowers, but also shows great potential in the field of healthy weight loss because of its chlorogenic acid component. Chlorogenic acid is an important component of green coffee extract. It is a phenylpropanoid compound produced by the plant body through the shikimic acid pathway during aerobic respiration, also known as coffee tannin. This compound is widely present in nature, but the chlorogenic acid content in green coffee is particularly rich.

[0013] Scientific verification shows that chlorogenic acid has the effect of inhibiting the absorption of glucose in the intestine. This characteristic makes chlorogenic acid unique in the field of healthy weight loss. When the body's sugar intake decreases, the body will look for energy sources that can replace sugar in order to maintain normal physiological functions. At this time, the body will turn to burning fat in adipose tissue as an energy source.

[0014] Moreover, chlorogenic acid reduces the risk of excessive sugar in food being converted into fat by inhibiting the intestinal absorption of glucose. At the same time, it can also adjust the nutritional structure of the human body and reduce the body fat ratio, thus achieving the goal of healthy weight loss. This weight loss method is not only effective, but also relatively safe, because it does not require extreme diet control or strenuous exercise to achieve.

[0015] (3) White kidney bean extract has attracted much attention because it is rich in α-amylase inhibitors, which play a key role in the digestion and absorption of carbohydrates in the human body. Specifically, the digestion and absorption of carbohydrates, especially starch polysaccharides, in the human body is a complex enzymatic reaction process. In this process, α-amylase plays a vital role. It is responsible for breaking down starch into disaccharides and monosaccharides that are more easily absorbed by the human body, such as maltose and glucose. The α-amylase inhibitor in white kidney bean extract has the ability to specifically bind to α-amylase. Once α-amylase binds to the α-amylase inhibitor, the α-amylase loses its activity, thereby blocking the hydrolysis process of starch. This specific binding is the key to the function of α-amylase inhibitors.

[0016] When foods containing carbohydrate-blocking ingredients are ingested, the α-amylase inhibitor in the white kidney bean extract will quickly bind to the α-amylase in the small intestine to form an enzyme inhibitor complex. The formation of this complex causes the α-amylase to be unable to continue to play its role in breaking down starch, so that starch cannot be further broken down into simple sugars such as glucose.

[0017] Due to the action of α-amylase inhibitors, the residence time of starch in the intestine is prolonged. This increases the chance of starch passing through the intestine instead of being absorbed, thereby reducing the amount of carbohydrates absorbed. This mechanism helps to lower blood sugar levels and reduce fat accumulation, which has positive significance for weight control and blood sugar management.

[0018] (4) L-carnitine is an essential carrier for fatty acids to enter mitochondria. It can accelerate the oxidation and decomposition of fatty acids, reduce fat accumulation, and convert fatty acids into energy, increase body energy consumption, promote fat burning, and achieve weight loss effects. In addition, L-carnitine can change the activity of respiratory enzymes in mitochondria, improve oxidation function, delay muscle fatigue, lower cholesterol and triglyceride levels, protect the heart, promote liver fat metabolism, and improve liver function, thereby helping to lose weight.

[0019] In particular, the coffee composition for preventing carbon and burning fat of the present invention is based on the theory of traditional Chinese medicine, and freeze-dried black coffee, green coffee extract, white kidney bean extract, and L-carnitine are selected, and these effective raw materials are combined to work together to prevent carbon and burn fat. Moreover, these raw materials can play a synergistic role in preventing carbon and burning fat, effectively promote fat metabolism, reduce fat accumulation, and assist in weight loss.

[0020] Secondly, the present invention provides a preparation process of a carbon-blocking and fat-burning coffee composition, comprising the following steps: S1. Making freeze-dried black coffee: S1-1. Selection: Select high-quality coffee beans, remove defective beans, foreign matter and broken beans to ensure the purity of the raw materials.

[0021] The preparation process of the present invention further adopts Arabica coffee beans.

[0022] In the above technical solution, Arabica coffee beans are selected as the core raw material because they have a mellow flavor, moderate caffeine content, and are rich in various ingredients that are beneficial to the human body. Studies have shown that drinking Arabica coffee in moderation can help increase the metabolic rate, reduce the risk of cardiovascular disease, prevent diabetes, etc., and also has the effect of refreshing the mind.

[0023] S1-2, roasting: roasting the selected coffee beans to obtain lightly roasted coffee beans.

[0024] The preparation process of the present invention is further characterized in that the baking temperature is 120-160° C. and the baking time is 20-30 minutes.

[0025] In the above technical solution, the degree of roasting has a crucial influence on the flavor and nutritional components of coffee beans. During the roasting process, as the temperature rises and the time prolongs, the coffee beans will gradually lose their original flavor and may produce a burnt feeling. In order to avoid this situation, this step adopts low-temperature roasting technology, and accurately controls the roasting temperature and time to obtain lightly roasted coffee beans. This not only retains the original flavor and nutritional components of the coffee beans, making the acidity of the coffee bright and prominent, the taste mellow, and the flavor fresh, but also avoids the harmful substances that may be generated by high temperature, ensuring the safety and health of the coffee.

[0026] S1-3, grinding: grinding and sieving the lightly roasted coffee beans to obtain roasted coffee powder.

[0027] S1-4, extraction: mix the roasted coffee powder and water evenly, then perform cold extraction and sieve filtering to obtain coffee liquid.

[0028] The preparation process of the present invention further has a mass ratio of roasted coffee powder to water of 1:10-12.

[0029] In the above technical solution, the less water used for extraction, the higher the concentration of the coffee liquid, but this wastes too much coffee powder and increases costs, so the mass ratio of roasted coffee powder to water is preferably 1:10-12.

[0030] The preparation process of the present invention is further characterized in that the cold extraction temperature is 1-4°C and the cold extraction time is 10-20h.

[0031] In the above technical solution, due to the cold extraction at 1-4°C for 10-20h, the tannic acid and other components in the obtained coffee liquid are less dissolved, the taste is smooth, with lower acidity, fresh and slightly sweet, and the taste is softer. At the same time, the aromatic substances are extracted at low temperature, making the coffee aroma rich. In addition, the long extraction time allows the caffeine to be fully extracted and the content is high.

[0032] S1-5. Concentration: The coffee liquid is concentrated by vacuum, and the concentration is stopped when the concentration of the coffee liquid reaches 50-60%, thereby obtaining concentrated coffee liquid.

[0033] S1-6, freeze drying: pre-freeze the concentrated coffee liquid at -30°C, and then freeze-dry it to obtain freeze-dried black coffee.

[0034] In the above technical solution, pre-freezing the concentrated coffee liquid at -30°C can not only make the internal structure of the coffee liquid more stable, but also reduce the drying time and ensure the quality stability of the product.

[0035] S2. Preparation of green coffee extract: S2-1, crushing: crushing the green coffee beans to obtain green coffee powder.

[0036] S2-2, extraction: add 85% ethanol to the green coffee powder, mix well, then heat, filter, and repeat the extraction of the filter residue several times, and combine the supernatant.

[0037] The preparation process of the present invention further has the mass ratio of green coffee powder to 85% ethanol being 1:5-10.

[0038] The preparation process of the present invention is further characterized in that the heating temperature is 80-90° C. and the heating time is 10-30 min.

[0039] S2-3, drying: the supernatant is concentrated under reduced pressure and dried, and then crushed to obtain green coffee extract S3. Mixing: Weigh freeze-dried black coffee, green coffee extract, white kidney bean extract and L-carnitine respectively by weight, sieve and mix them evenly, and then bag them to obtain the carbon-blocking and fat-burning coffee composition.

[0040] Thirdly, the present invention provides a carbon-blocking and fat-burning coffee composition for use in preparing a weight-loss product.

[0041] Compared with the prior art, the beneficial effects and technical advantages of the present invention are as follows: (1) Important roles of each raw material: First, green coffee extract is rich in chlorogenic acid, which inhibits the activity of glucose-6-phosphatase and reduces the intestinal absorption of glucose, especially when the glucose supply is insufficient, promoting the body to use stored fat as energy and accelerating fat burning. Secondly, white kidney bean extract inhibits the activity of α-amylase and reduces the absorption of glucose, effectively controlling carbohydrate intake, while promoting the decomposition and utilization of fat, providing a scientific theoretical basis for healthy weight loss. Furthermore, freeze-dried black coffee can increase the body's calorie consumption, accelerate fat decomposition, and stimulate the central nervous system to enhance the brain-awakening effect. Finally, L-carnitine can improve fat burning efficiency, accelerate fat decomposition, assist weight loss, and reduce fat accumulation. In particular, the present invention is based on the theory of traditional Chinese medicine and carefully combines the above raw materials, aiming to effectively suppress appetite and promote fat burning and weight loss through the synergistic effect of natural ingredients.

[0042] (2) Comprehensive efficacy of the product: The coffee composition product of the present invention not only has the efficacy of stimulating the sympathetic nerves, arousing emotions, making the mind clear and agile, and eliminating fatigue and sleepiness, but also has the efficacy of promoting fat burning, suppressing appetite, and reducing weight. It is especially suitable for coffee lovers who want to lose weight. It can not only enhance brain wakefulness, but also suppress appetite, promote fat burning, and reduce weight, killing two birds with one stone.

[0043] (3) Technical advantages and safety: The raw materials of the present invention are widely available, ensuring sustainable production of the product. The raw materials are safe and have no side effects, protecting the health of consumers. The preparation cost is low, achieving an economical and efficient production process, and meeting modern environmental protection requirements, achieving clean and energy-saving production.

[0044] In summary, the composition of the present invention is an innovative product that combines refreshing the mind with weight loss and fat reduction. It can not only meet the taste needs of coffee lovers, but also help them achieve the goal of healthy weight loss. In the future, as people's pursuit of healthy life becomes increasingly stronger, this coffee composition with dual functions is expected to become a popular product on the market.

[0094] In addition, the preparation process of the carbon-blocking and fat-burning coffee composition is the same as that of Example 1.

[0095] Experiment 1: Analysis of experimental body weight gain and fat / body ratio results in rats.

[0096] Experimental purpose: To observe the effect of the test sample (obesity model) on the body weight and body fat content of rats.

[0097] Experimental principle: Induce animals to become obese with high-calorie food, then give them test samples (obesity model) and observe the changes in the animals' weight and body fat content.

[0098] Experimental method: 120 SPF SD male rats were selected and randomly divided into: 8 blank control groups, fed with normal feed; 112 modeling groups, fed with nutritious feed. Both groups had normal drinking water for 6 consecutive weeks and were weighed. The modeling group was compared with the blank control group. If there was a significant difference in the weight of the rats, it indicated that the obesity model was successfully established.

[0099] 96 obesity-sensitive rats were selected from the modeling group and randomly divided into 12 groups, including: a model control group, which continued to be fed with nutritious feed; Example groups 1-3 were respectively fed with the compositions prepared in Examples 1-3, and continued to be fed with nutritious feed; Comparative example groups 1-8 were respectively fed with the compositions prepared in Comparative examples 1-8, and continued to be fed with nutritious feed. In addition, the blank control group continued to be fed with normal feed. All groups had normal drinking water for 6 consecutive weeks.

[0100] Evaluation indicators: After the experiment, the rats were weighed and anesthetized with 1% sodium pentobarbital (0.5 ml / 100 g BW). The perinephric fat and perinephric fat were dissected and weighed, and the fat / body ratio was calculated. The weight gain is shown in the following table.

[0101]

[0102] Depend on Figure 2 It can be seen that after the experiment, the fat weight and fat / body ratio of rats in the model control group, example groups 1-3, and comparative example groups 1-8 increased significantly compared with the blank control group. The fat weight and fat / body ratio of rats in example groups 1-3 were significantly lower than those in the model control group, indicating that the coffee composition prepared in the example has the effect of promoting fat burning and inhibiting weight gain. Although the fat weight and fat / body ratio of rats in comparative example groups 1-8 were lower than those in the model control group, they were not as good as the weight loss effect of the example group, reflecting the influence of different coffee composition components on fat weight and fat / body ratio.

[0103] Experiment 2: Human efficacy experiment.

[0104] Experimental subjects: Subject inclusion criteria: aged between 18 and 60 years old, simple obesity. Subject exclusion criteria: patients with serious diseases such as heart, liver, kidney and hematopoietic system, mental illness, and any other person who may affect the judgment of the results. 120 subjects who met the criteria were selected on a voluntary basis.

[0105] Experimental method: 120 subjects were randomly divided into 12 groups, 10 subjects in each group, including: Example groups 1-3, respectively consuming the coffee composition prepared in Examples 1-3, brewing and drinking twice a day, 3g each time; Comparative example groups 1-8, respectively consuming the coffee composition prepared in Comparative examples 1-8, brewing and drinking twice a day, 3g each time; blank control group, drinking the same dose of water. Consume for 30 days continuously, record and compare the weight changes of each group before and after the experiment, and the weight gain is shown in the following table.

[0106]

[0107] Depend on Figure 3 It can be seen that the weight of the subjects in the blank control group did not change substantially, which indicates that during the experiment, the subjects in the blank control group did not experience significant changes in weight due to other external factors (such as diet, exercise, etc.), thereby verifying the effectiveness of the experimental control. Although the weight of the subjects in the comparative example groups 1-8 also decreased, the decrease was significantly less than that in the example groups 1-3, which indicates that although the coffee composition prepared in the comparative example 1-8 also has a certain weight loss effect, the effect is not as significant as that in the example group. The weight of the subjects in the example groups 1-3 decreased significantly, and the decrease was large, which indicates that the coffee composition prepared in the example 1-3 has a significant weight loss effect on people with simple obesity. This is due to its unique formula and preparation process, which enables the active ingredients in the coffee composition to play a better role.

[0108] Based on the results of Experiment 1 and Experiment 2, the subjects who consumed the coffee composition of the present invention had a significant reduction in body weight, which indicates that the composition has an effective effect of blocking carbohydrate absorption and helps to reduce calorie intake. At the same time, the weight reduction of the subjects in the Example group was significantly greater than that in the Comparative Example group, indicating that the coffee composition of the present invention can not only block carbohydrates, but also promote the burning and decomposition of fat and accelerate body metabolism.

[0109] It should be noted that the present invention is based on the theory of traditional Chinese medicine, and freeze-dried black coffee, green coffee extract, white kidney bean extract, L-carnitine and other effective raw materials are preferably selected for compatibility, thereby ensuring the scientificity and effectiveness of the composition. In addition, the various raw materials in the coffee composition of the present invention are all substances of medicinal and edible origin, which are safe and reliable. After these raw materials are made into a composition in a certain proportion, the beneficial effects on the human body are incomparable to those of a single component. In particular, through the careful adjustment of the components and their dosages, the coffee composition of the present invention achieves a synergistic effect. The raw materials interact with each other to jointly promote body metabolism, accelerate fat burning, and reduce body weight.
