Description

Technical Field

[0001] The present invention belongs to the technical field of functional foods, and in particular relates to a yogurt-like ketogenic product with a sweet and sour taste and a preparation method thereof. Background Art

[0002] With the development of society, obesity has become more and more serious and has gradually attracted people's attention. Obesity brings many inconveniences to people's lives and threatens physical and mental health. Studies have shown that obese patients are prone to many complications such as chronic diseases such as diabetes, hypertension, and hyperlipidemia, and the incidence increases with the degree of obesity. Obviously, obesity has caused a huge negative impact on people's physical health, so it is extremely important to prevent and treat obesity. The causes of obesity are extremely complex and are related to genetics, diet and exercise, so obese people should pay special attention to their diet.

[0003] Studies have shown that dietary control is the key to preventing obesity and promoting weight loss in obese patients. The ketogenic diet is a high-fat, low-carbohydrate, moderate-protein diet. With the application of this dietary therapy, it was found that patients who adopted this diet also lost weight. The ketogenic diet is an efficient weight management diet that can achieve significant weight loss effects. The normal human body uses glucose as an energy source, while the ketogenic human body uses ketone bodies as an energy source. Glucose is a metabolic product of carbohydrates, and ketone bodies are metabolic products of fat. Therefore, the ketogenic diet will reduce the intake of carbohydrates in the body, resulting in insufficient glucose storage, forcing the body to burn fat, and the fatty acids produced by fat decomposition eventually form ketone bodies in the liver, which are used by the body to replace glucose to provide energy, thereby promoting weight loss in obese patients.

[0004] Yogurt, with its rich nutritional value and sweet and sour silky and thick taste, has gradually become popular among people of different ages. A survey shows that the vast majority of residents like to drink yogurt and like the taste of yogurt, and only 10% of residents do not like to drink yogurt.

[0005] Most of the ketogenic products on the market are solid ketogenic powders, and a small number are milk-like liquid ketogenic drinks with good fluidity. So far, there are no ketogenic products that are made into yogurt, sweet and sour taste, can be stored at room temperature, and have a shelf life of more than 12 months. Summary of the invention

[0006] The purpose of the first aspect of the present invention is to provide a ketogenic product.

[0007] The purpose of the second aspect of the present invention is to provide a method for preparing the ketogenic product of the first aspect of the present invention.

[0008] The purpose of the third aspect of the present invention is to provide the use of the ketogenic product of the first aspect of the present invention in the preparation of ketogenic weight loss food.

[0009] In order to achieve the above object, the technical solution adopted by the present invention is:

[0010] The first aspect of the present invention provides a ketogenic product, comprising the following components: ketogenic powdered oil, a sweetener, an acidity regulator and a composite powder; wherein the ketogenic powdered oil is a microcapsule powder embedded with a casein wall material.

[0011] Ketogenic powder oil generally refers to oils composed of short-chain and medium-chain fatty acids. Ordinary cooking oils are oils composed of long-chain fatty acids, which are first hydrolyzed in the small intestine, then re-esterified into triglycerides, and then formed into chylomicrons together with proteins, and then absorbed through the intestinal wall, and then enter the blood circulation system through the lymphatic system, and transported to the liver, storing fat and other tissues. Simply put, ordinary cooking oils store fat and cause obesity. Short-chain and medium-chain fatty acids are absorbed differently. Instead of being transported directly into the body, they are transported directly to the liver, where they can be converted into ketone bodies and used as a quick energy source, and the digestion and decomposition rate is about dozens of times that of long-chain fatty acids. In addition, compared with long-chain fatty acids, they are less likely to be stored as fat.

[0012] In some embodiments of the present invention, the ketogenic powdered fat includes at least two of medium-chain triglyceride powder, coconut oil powder, butter powder, palm kernel oil powder, cocoa butter powder, cream powder and Brazilian palm oil powder.

[0013] In some embodiments of the present invention, the ketogenic powdered fat includes at least two of medium chain triglyceride powder, coconut oil powder and butter powder.

[0014] Medium chain triglycerides are a type of fatty acid that is mainly found in coconut oil. Medium chain triglycerides can increase the body's metabolic rate, speed up the burning of calories, promote calorie consumption and energy metabolism in the diet, and improve the body's sugar and lipid metabolism. It can reduce the accumulation of body fat and hunger between meals, and prevent overeating. The advantage of medium chain triglycerides is that they can be quickly digested and absorbed without the need for pancreatic lipase hydrolysis, and their absorption does not require the participation of the lymphatic system. Medium chain triglycerides are metabolized in the liver, do not synthesize fatty acids, and are not stored as body fat. Their oxidative metabolism produces ketone bodies, which can quickly provide energy for the human body, thereby controlling energy intake and storage. Therefore, medium chain triglycerides have a significant weight loss effect.

[0015] Effectively combine ketogenic powdered oils such as medium-chain triglyceride powder with coconut oil powder and butter powder to promote each other. Adopt the principle of low-carbon ketosis. After reducing carbohydrate intake, the human body changes from using carbohydrates to obtain energy to using fat as the main energy source, which can achieve weight loss effect.

[0016] In some embodiments of the present invention, the composite flour comprises β-1,3 / α-1,3-glucan, yeast protein and hydrolyzed wheat endosperm extract.

[0017] β-1,3 / α-1,3-glucan can enhance immunity, regulate intestinal flora, reduce fat absorption and other functions. It is a very powerful functional raw material and is very suitable for ketogenic people; at the same time, it has good water solubility, acid and alkali resistance, heat resistance and other processing characteristics. Adding it to the ketogenic products of the present invention can improve the texture and nutritional value of the product. After a large number of experiments, the inventor found that adding β-1,3 / α-1,3-glucan can play a good thickening role, can make the texture of ketogenic products uniform and delicate, and prevent stratification. The amount of addition has a certain range requirement. If the amount added is too little, the ketogenic product cannot be formed into a delicate and uniform state. If too much is added, the texture is too thick, the mouthfeel is sticky, and the throat is choked. The ketogenic product according to the embodiment of the present invention has excellent efficacy, excellent flavor, taste and state, and strong stability.

[0018] Yeast protein is completely digested and absorbed at the end of the small intestine. It is a typical "slow protein" with the characteristic of "slow digestion". It is also called slow-release protein. Yeast protein can prolong the feeling of fullness. People who lose fat can control energy by enhancing their feeling of fullness. It is very suitable for people who lose weight by ketogenic diet. After a large number of experiments, the inventors found that adding yeast protein can increase the viscosity and solid content of ketogenic products, giving the products a silkier and softer taste. The amount of addition has a certain range requirement. If the amount added is too little, the ketogenic product cannot be improved to have a silkier and softer taste. If the amount added is too little, the yeast taste of the yeast protein is too heavy, which will affect the taste of the ketogenic product and make it difficult for consumers to accept it. The ketogenic product according to the embodiment of the present invention has excellent efficacy, excellent flavor, taste and state, and strong stability.

[0019] Hydrolyzed wheat endosperm extract is wheat endosperm extract. Wheat can be divided into three major components, namely endosperm, bran and germ, and the main part used for extraction is wheat endosperm, which accounts for about 85% of the weight of wheat. Wheat endosperm is rich in α-amylase inhibitors, which can inhibit the action of amylase, making it difficult for starch in food to be decomposed and converted into glucose in the mouth and small intestine, thereby reducing the absorption and utilization of glucose, which is particularly suitable for high-fat and low-carbon ketogenic fat-reducing people. Hydrolyzed wheat endosperm extract is also a protein powder, most of its protein can resist the decomposition of pepsin and trypsin, so it is not absorbed and is directly excreted from the body through the intestines, without increasing the burden on the liver and kidneys, and without any side effects. After a large number of experiments, the inventor found that hydrolyzed wheat endosperm extract can simultaneously increase the protein content and solid content of ketogenic products, so that ketogenic products can be better condensed and not stratified. There is a certain range requirement for its addition amount. If the addition amount is too little, the effect of blocking starch cannot be achieved. If the addition amount is too much, the taste of plant protein is too strong, which will affect the taste of ketogenic products and make it difficult for consumers to accept. The ketogenic product according to the embodiment of the present invention has excellent efficacy, excellent flavor, taste and state, and strong stability.

[0020] In some embodiments of the present invention, the sweetener includes at least one of erythritol, sorbitol, maltitol, maltitol, lactitol, sucralose, aspartame, acesulfame potassium, steviol glycosides and mogrosides.

[0021] Sweeteners do not participate in the body's metabolism. Most high-intensity sweeteners are excreted intact after oral ingestion and do not provide energy. They are suitable for special consumer groups such as diabetics, obese people and the elderly who need to control energy and carbohydrate intake. They are not suitable substrates for oral microorganisms and will not cause tooth decay.

[0022] In some embodiments of the present invention, the sweetener is erythritol. Erythritol is a sweetener that contains essentially no calories and is not metabolized by human enzymes. It does not provide basic energy for the human body and does not participate in sugar metabolism. Secondly, it is not used by oral bacteria and can protect the oral cavity well. Adding it to yogurt can increase its sweetness without affecting insulin or blood sugar levels.

[0023] In some embodiments of the present invention, the acidity regulator includes at least one of citric acid, lactic acid, malic acid, tartaric acid, phosphoric acid, acetic acid, sodium citrate, sodium lactate, sodium malate, sodium tartrate, sodium phosphate, disodium hydrogen phosphate, sodium dihydrogen phosphate, sodium carbonate, sodium bicarbonate, sodium hydroxide, sodium acetate, potassium citrate, potassium lactate, potassium malate, potassium tartrate, potassium phosphate, dipotassium hydrogen phosphate, potassium dihydrogen phosphate, potassium carbonate, potassium bicarbonate, potassium hydroxide and potassium acetate.

[0024] The main function of acidity regulator in yogurt is to adjust the pH and cause protein flocculation to form a viscous state.

[0025] In some embodiments of the present invention, the acidity regulator is citric acid. Citric acid, also known as citric acid, is an odorless, colorless crystal with a strong sour taste. Because it is easily soluble in water, it is often used in the preparation of yogurt as an acidity regulator to adjust the acidity, so that the yogurt has a mild and refreshing sour taste, and quickly reaches the highest sourness after entering the mouth, while adjusting the acidity and alkalinity.

[0026] In some embodiments of the present invention, the ketogenic product includes, by weight, 10 to 60 parts of ketogenic powdered oil, 5 to 25 parts of sweetener, 0.1 to 2 parts of acidity regulator, and 0.5 to 5 parts of composite powder.

[0087] Effect Example

[0088] 1. Sensory evaluation

[0089] The ketogenic products prepared in Examples 1 to 7 and Comparative Example 1 were evaluated. The sensory evaluation items consisted of four aspects: color, tissue state, taste, and flavor. The four items were combined to form the final score of the sensory evaluation. The sensory evaluation standards are shown in Table 1. 10 professional sensory evaluators were selected, who had sensitive taste, color, and smell functions and had a certain ability to express the description of ketogenic products.

[0090] The average value is calculated based on the scoring results of each taster, and the average value of the scores is finally used as the result of the sensory evaluation of the product's edible quality. The calculation result is rounded to an integer. The four dimensions of color, texture, taste, and flavor are evaluated, with each dimension standard being 25 points and the total score being 100 points. When the sensory score is greater than 80 points, the overall sensory quality of the sample is good, between 50-80 points is average, and less than 50 points is poor. The sensory evaluation standards are shown in Table 1, and the sensory evaluation results are shown in Table 2.

[0091] Table 1 Sensory evaluation standards are as follows

[0092]

[0093] Table 2 Sensory evaluation results

[0094]

[0095]

[0096]

[0097] As can be seen from Table 2, the sensory scores of the ketogenic products of Examples 1 to 4 and Example 6 are relatively high, reaching 90 points or above; the scores of Example 5 and Example 7 are relatively low, below 80 points; the drink made in Comparative Example 1 is not as thick as yogurt, but as watery as milk.

[0098] 2. Stability assessment

[0099] The stability assessment is mainly carried out from the aspects of sensory index, physical and chemical index, microbiological index, etc. (Table 3), and the follow-up assessment is carried out for 15 months under room temperature conditions. If one of the indicators does not meet the standard, the stability follow-up assessment will no longer be carried out.

[0100] Sensory indicators: The sensory evaluation test of the ketogenic products of Examples 1 to 7 and Comparative Example 1 during storage was conducted, and products stored at room temperature for 0 days, 6 months, 12 months, and 15 months were selected for sensory evaluation (evaluation standards are shown in Table 1).

[0101] Physical and chemical indicators:

[0102] pH value determination: refer to GB 5009.237.

[0103] Determination of total solid content: refer to GB / T 12143.

[0104] Fat content determination: refer to GB 5009.6.

[0105] Microbiological indicators: total colony count shall refer to GB 4789.2, coliform bacteria shall refer to GB 4789.3, mold shall refer to GB 4789.15, yeast shall refer to GB 4789.15.

[0106] Table 3 Stability evaluation index requirements

[0107]

[0108] Table 4 15-month stability follow-up evaluation results

[0109]

[0110]

[0111] As can be seen from Table 4, the ketogenic products of Examples 1 to 3 are qualified in all aspects when stored at room temperature for 12 months, and Example 3 is also qualified after 15 months; the hydrolyzed wheat endosperm extract of Example 4 is used in a small amount, and its various indicators are good, but its sensory requirements are not qualified after 12 months under room temperature storage. The reason is analyzed as follows: the protein content and solid content of the ketogenic product of this example are relatively low, and stratification is prone to occur over time; the β-1,3 / α-1,3-glucan used in Example 5 is small, and the sensory evaluation is unqualified on the 0th day. The reason is analyzed as follows: the β-1,3 / α-1,3-glucan used in a small amount cannot thicken, and the water liquid is stratified and precipitated; Comparative Example 1 uses a fat powder that is not a casein wall material for embedding, so it cannot be made into a yogurt-like consistency, but is as watery as liquid milk; Example 6 uses low-temperature long-term sterilization, so the microorganisms are unqualified on the 0th day; Example 7 uses high-temperature short-time sterilization, so the microorganisms are unqualified on the 0th day.

[0112] Subsequently, Examples 1 to 4 were used to evaluate the ketogenic weight loss effect.

[0113] 3. Evaluation of the effect of ketogenic weight loss

[0114] The ketogenic products in Examples 1 to 4 were evaluated for their application effect on human ketogenic weight loss.

[0115] The subjects were simple obese people, adult BMI ≥ 30.0, or voluntary subjects with a total fat percentage of > 25% for males and > 30% for females. The volunteers were aged 19 to 59 years old, a total of 100 people. The volunteers were divided into an experimental group (divided into 4 groups according to Examples 1 to 4, 20 people in each group) of 100 people and a control group of 20 people.

[0116] The volunteers in the experimental group consumed 2 bags of the ketogenic product for breakfast every day, and did not take other products of the same type during the trial. The volunteers in the control group did not take any products of the same type. During the trial, they maintained their regular diet, physical activity and lifestyle. The test samples were given for 60 days. The physical indicators of all volunteers (weight, BMI value, abdominal circumference, hip circumference, waist circumference, upper arm circumference, thigh circumference) were recorded before and after the test.

[0117] The reference values ​​for blood ketone monitoring during the use of this product are: <0.2mmol / L no ketosis; 0.2-0.5mmol / L mild ketosis; 0.5-3mmol / L ketosis diet; 2.5-3.5mmol / L ketosis after exercise; 3-6mmol / L starvation ketosis; 10-25mmol / L ketoacidosis, excessive blood ketones, acidic blood, harmful to the human body. To ensure that the body's blood ketone value is in the ketosis diet state of 0.5-3mmol / L, experimental volunteers need to strictly control carbohydrate intake according to their own situation.

[0118] The changes in body weight before and after the experiment are shown in Table 5.

[0119] Table 5 Physical indicators before and after the test

[0120]

[0121] Note: * indicates significant difference compared with before the experiment (P<0.05).
