Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0030] In order to solve the problems of low nutritional value, high fat and sugar content, and a large number of preservatives and other additives in traditional meal replacement bars, the present invention proposes a defatted peanut meal replacement bar, which uses defatted peanuts as the main ingredient, supplemented by yam powder, defatted peanut powder, pumpkin seeds, xylitol, peanut flavor, etc. The obtained defatted peanut meal replacement bar is rich in nutrition and low in fat and sugar content, and also reduces the addition of preservatives and other additives. Specifically, in one embodiment of the defatted peanut meal replacement bar provided by the present invention, the defatted peanut meal replacement bar includes the following raw materials: 28-32g defatted peanut kernels, 8-12g yam powder, 8-12g defatted peanut powder, 10-13g xylitol, 3-5g peanut flavor, 0.3-0.5g baking soda, 5-8g pumpkin seeds and 17.5-37.7g pure water. The appearance of the defatted peanut meal replacement bar can be, for example, a round bar, a square bar, etc. Figure 1 Shown is a picture of the appearance of a specific embodiment of the defatted peanut meal replacement bar provided by the present invention, which is shiny as a whole and has rich and attractive colors.

[0031] The technical solution provided by the present invention mainly has the following beneficial effects:

[0032] (1) The defatted peanut kernels are used as the main ingredients, supplemented with yam powder, defatted peanut powder, pumpkin seeds, xylitol, peanut essence, baking soda and other rich ingredients and safe additives. The defatted peanut meal replacement bars are nutritious and have a good taste. Compared with traditional meal replacement bars, they have lower sugar and fat content and less preservatives. They can meet health needs and are suitable for people who need to lose weight, providing consumers with a healthier choice.

[0033] (2) Defatted peanut kernels and yam powder are used to replace traditional peanut kernels and whole wheat flour as the basic ingredients. Defatted peanut kernels retain most of the high-quality plant protein of peanuts, which has a rich amino acid composition and high absorption rate. They are also rich in vitamin E, B group vitamins, and minerals such as calcium, magnesium, and zinc. They can supplement nutrition for the human body and have antioxidant effects and maintain the normal function of the nervous system. Yam powder contains digestive enzymes such as amylase, which is conducive to digestion and absorption. It is rich in mucus protein, vitamins, trace elements, and dietary fiber, which can strengthen the spleen and stomach, nourish the kidneys and essence, and prevent cardiovascular diseases. Both have unique nutritional value and can provide support for human health from different aspects.

[0034] (3) The addition of pumpkin seeds improves the taste and nutritional value of the product. Pumpkin seeds contain vitamin E, B vitamins, and a variety of trace elements necessary for the human body, such as zinc, magnesium, iron, potassium, etc. They not only increase the color of the defatted peanut meal replacement bar, but also give it a unique cereal aroma, thereby improving the overall taste experience.

[0035] (4) Use xylitol to replace sucrose. Compared with sucrose, xylitol has lower calories and can help reduce calorie intake and help control weight. Xylitol has a lower glycemic index and is suitable for diabetic patients. Xylitol can also inhibit the acid production of oral bacteria and play a role in preventing tooth decay. In addition, it can promote the growth of beneficial intestinal bacteria and help improve intestinal function.

[0036] (5) Peanut flavor has the advantages of outstanding and stable fragrance, low cost and high efficiency. If used in an appropriate amount, it can greatly improve the flavor of the product.

[0037] Based on the above-mentioned defatted peanut meal replacement bar provided by the present invention, the present invention also provides a method for preparing the defatted peanut meal replacement bar. Figure 2 The figure shows an embodiment of the method for preparing the defatted peanut meal replacement bar provided by the present invention. Figure 2 As shown, in this embodiment, the preparation method of the defatted peanut meal replacement bar includes the following steps:

[0038] Step S10: washing the defatted peanut kernels, boiling them, drying them, and crushing them to make defatted peanut crumbs;

[0039] Step S20: uniformly mixing the defatted peanut pieces with yam powder, defatted peanut powder, xylitol, peanut essence, baking soda, and pumpkin seeds, then adding purified water and stirring into a paste, and then pressing into a cake embryo;

[0040] Step S30: placing the dough into a microwave oven for baking and cooking to obtain a defatted peanut meal replacement bar.

[0041] First, complete and mold-free defatted peanut kernels are screened and washed. Water is added to cover the kernels, which are then removed from the washing process and boiled in boiling water to remove any rancid odor. After boiling, the kernels are removed from the boiling process, dried, and crushed into appropriately sized peanut particles to produce defatted peanut crumbs. The defatted peanut crumbs are then mixed with yam powder, defatted peanut powder, xylitol, peanut essence, baking soda, and pumpkin seeds. Purified water is then added and stirred into a paste. The mixture is then pressed into a cake to form a base. The base is then covered with absorbent paper and microwaved to bake. This results in a defatted peanut meal replacement bar.

[0042] During the baking and curing process, the microwave oven can effectively kill bacteria, molds, yeasts and other microorganisms in the food through the high temperature environment. In this way, in the sealed state after subsequent packaging, the food can maintain a relatively sterile state for a long time, which is conducive to extending the shelf life of the meal replacement bar and reducing the dependence on preservatives. Moreover, compared with traditional sterilization methods, sterilization during microwave baking and curing can maximize the preservation of the nutritional components and flavor of the food while ensuring the sterilization effect. In addition, it should be noted that when preparing the cake embryo in step S20, the cake embryo can be made into the required size, and after the baking and curing in step S30, there is no need to cut it, that is, a meal replacement bar product of the appropriate size is obtained; alternatively, a large cake embryo can be made, and after the baking and curing in step S30, it can be cut into appropriate sizes to obtain a meal replacement bar product of the desired size.

[0043] Preferably, in some embodiments of the present invention, the defatted peanut kernels are obtained through cavitation treatment. Specifically, cavitation-treated defatted peanut kernels provided by New Era Food Technology (Foshan) Co., Ltd. can be used. These kernels offer significant advantages over conventional peanut kernels. Conventional peanut kernels have a fat content of 44-45% and a protein content of 24-36%. However, after four cycles of oil extraction during cavitation treatment, the fat content of defatted peanut kernels can be reduced to 3.8%, while the protein content is increased to 47%, significantly reducing the likelihood of peanuts becoming oxidatively rancid. Furthermore, compared to other high-temperature degreasing techniques, such as high-temperature pressing, which destabilizes vitamins B1 and B2 and oxidizes antioxidant vitamins like vitamin E, cavitation treatment operates at low temperatures, minimizing the loss of fat-soluble vitamins like vitamin E and water-soluble vitamins like vitamin B due to the relatively gentle degreasing process. Furthermore, protein activity can be increased to 98%, giving defatted peanut kernels excellent emulsifying properties and gel strength, resulting in a more nutritionally balanced and healthier diet, which is of great significance for those who need to control their fat intake. In addition, the defatted peanut kernels that have undergone cavitation treatment not only reduce the fat content of the peanuts, but also take into account the appearance, texture, taste and nutrition of the final peanut kernels.

[0044] Specifically, in some embodiments of the present invention, step S10 includes: first screening with a screening machine to remove impurities such as broken peanut particles, peanut skins, and shrunken particles, then performing color sorting to remove moldy particles and particles of different colors, and then washing the defatted peanut kernels obtained by screening, adding water to cover the peanut kernels, and after washing, taking them out and putting them into a pot and boiling them in boiling water for 3 to 5 minutes to remove the rancid smell of the peanut kernels; then controlling the water, taking them out and putting them into a microwave oven to dry on medium heat; and then putting them into a wall breaking machine to break them into particles of suitable size to make defatted peanut crumbs.

[0045] The present invention utilizes a microwave oven for drying, which is fast, efficient, uniform, energy-efficient, environmentally friendly, simple to operate, and safe and hygienic. The microwave oven's power refers to the speed of temperature rise controlled by adjusting the output power, and is categorized as "high," "medium-high," "medium," "medium-low," and "low." The rated output power of a microwave oven generally ranges from 500 to 1000W. Typically, the highest power (high) of a microwave oven can reach 100% of the rated output power, while "medium-high" is approximately 80%, "medium" is approximately 60%, "medium-low" is approximately 40%, and "low" is approximately 20%. Specifically, in some embodiments of the present invention, the microwave oven power during the medium-heat drying process is 450 to 550W, and the drying time is 100 to 150 seconds. Under these conditions, defatted peanut kernels can be dried quickly and safely. More preferably, the microwave power of the medium-heat drying is 500W, and the drying time of the medium-heat drying is 120s.

[0046] Furthermore, in some embodiments of the present invention, the crushing process uses a crushing machine with a power of 450-550W and a crushing time of 25-35 seconds. Under these conditions, the defatted peanut crumbs are approximately one-third to one-half the size of the original whole peanut kernels, which helps to make the resulting defatted peanut meal replacement bar have a crisper texture. More preferably, the crushing process uses a crushing machine with a power of 500W and a crushing time of 30 seconds.

[0047] In some embodiments of the present invention, step S30 includes: placing the cake embryo in a microwave oven, first baking it with medium heat for 100 to 150 seconds, turning it over to absorb excess moisture, continuing to bake it with medium heat for 100 to 150 seconds, turning it over (absorbing excess moisture), then baking it with medium to low heat for 40 to 80 seconds, turning it over (absorbing excess moisture), continuing to bake it with medium to low heat for 40 to 80 seconds, turning it over (absorbing excess moisture), continuing to bake it with medium to low heat for 40 to 80 seconds, cooling it, and making a defatted peanut meal replacement bar. By baking it with medium heat twice and baking it with medium to low heat three times, during this process, the cake embryo completes maturation, and also completes sterilization under the high temperature environment of the microwave oven, effectively killing various microorganisms such as bacteria, molds, yeasts, etc. in the food, while ensuring the sterilization effect, the nutritional components and flavor of the food are retained to the greatest extent. In some preferred embodiments of the present invention, the time for baking it with medium heat twice in step S30 is preferably 120 seconds, and the time for baking it with medium to low heat three times in step S30 is preferably 60 seconds.

[0048] Furthermore, in some embodiments of the present invention, the power of the microwave oven for medium-fire baking is 450-550W, preferably 500W.

[0049] In addition, in some embodiments of the present invention, the power of the microwave oven for medium-low heat baking is 200-230W, preferably 210W.

[0050] The defatted peanut meal replacement bar provided by the present invention is a high-quality choice for modern healthy diet. It is carefully made by integrating advanced production technology and has many significant advantages. From the perspective of eating experience, it realizes the improvement of the degree of freedom in eating scenes and time. Whether consumers are in a busy work interval, before and after fitness, or on the way, as long as they carry a meal replacement bar, they can eat and replenish energy at any time, which greatly improves the convenience. From a nutritional point of view, defatted peanuts retain rich high-quality plant protein, multiple vitamins and minerals, and are matched with other nutrients.

[0108]

[0109] Table 2 Sensory evaluation results

[0110]

[0111] According to the sensory evaluation results in Table 2, the comprehensive scores of the defatted peanut meal replacement bars prepared in the examples are higher than those in the comparative examples.

[0112] In addition, comparing Comparative Example 1 with the Example, sucrose was used instead of the xylitol in the present invention. While the sweetness of the product was similar, the comparative example product left a caramel taste in the mouth for a longer period after chewing. In contrast, the xylitol in the Example product had a purer sweetness without any peculiar smell, and no aftertaste remained in the mouth. This indicates that the use of xylitol in the present invention, in place of sucrose, not only acts as a sweetener but also reduces the aftertaste in the mouth. Furthermore, it has the advantages of reducing calorie intake and lowering blood sugar fluctuations.

[0113] Comparing Comparative Example 2 with the Example, the addition of baking soda was omitted in Comparative Example 2, resulting in a product that was relatively hard and less crisp after baking and curing, and a significantly lower taste than the Example. This indicates that the addition of baking soda in the present invention provides a fluffy texture, preventing the product from being too hard or too tight, and making the defatted peanut meal replacement bar more crispy and delicious.

[0114] The above are merely preferred embodiments of the present invention and are not intended to limit the scope of the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of the present invention.
