Description

Low Glycemic Index (GI) nutritional meal replacement biscuit and industrial mass production method thereof
The invention relates to the technical field of nutritional food production, in particular to a nutritional meal replacement biscuit with a low Glycemic Index (GI) and an industrial mass production method thereof, and particularly relates to a nutritional meal replacement biscuit with a low glycemic index and high unsaturated shortening rich in medium-long chain fatty acid and an industrial mass production method thereof.
Background
The high-speed development of social economy, the accelerated pace of life and the high-speed development of food industry change the eating habits and food compositions of people, a large amount of fine-processed convenient and quick foods appear, the consumption of high-sugar and high-oil foods is increased at a high speed, so that the problems of excessive daily dietary energy intake, unbalanced nutrient intake and year-by-year increase of the prevalence rate of overweight and obesity are caused, and the popularization situation is presented. According to 2016 edition of the experts' medical nutrition therapy for overweight/obesity in China, obesity is a potential risk factor for diabetes, cardiovascular diseases and other metabolic diseases and tumors. It is well known in the consensus that obesity is often the result of a combination of heredity, paucity and excessive energy intake, and that obese people are often characterized by lipid metabolism disorders, excessive fat synthesis, and no significant abnormalities in fat hydrolysis and fat oxidation. Plasma triglycerides, free fatty acids and cholesterol are generally higher than normal levels.
Recently, the "Glycemic Index" concept (GI, Glycemic Index) has been proposed in nutrition, which is an Index reflecting the degree of elevation of blood glucose in a human body by food, and is a response state of blood glucose production in a human body after eating. Simply stated, the higher the GI, the greater the magnitude of the rise in blood glucose. Especially, in the food industry, excessive processing of food, such as polished rice flour, refined sugar and the like, abandons dietary fiber, causes loss of a large amount of nutrients and mineral substances, and people eat a large amount of the finished carbohydrate, and after digestion and absorption, the carbohydrate is quickly hydrolyzed into glucose, so that the blood sugar is increased too fast, a human body secretes a large amount of insulin, the glucose in blood is converted into fat, the weight is increased, and overweight and obesity are caused. Meanwhile, blood sugar in blood is rapidly reduced, so that a person feels hunger, and the person is induced to eat again, thereby causing vicious circle. Therefore, controlling the drastic fluctuations in blood glucose (polyphagic low GI foods) is an important factor to consider for overweight or obesity.
Australia has developed over 20 years of international collaboration, research and practice AS national Standard AS 4694-. The International organization for standardization ISO, which is based on the FAO/WHO recommendation method, published under the Australian standards of ISO 26642:2010 Food product-Determination of the physiological index (GI) and recommendation for Food classification. According to this standard, the GI value is the available carbohydrate in the food, the time is the abscissa, the blood glucose level at each time point is the ordinate, a blood glucose response curve is created, the area under the blood glucose line is calculated, the GI value with the glucose reference is 100, and the GI value of the test food is calculated. Thus, the GI reacts to the response of available carbohydrates in food versus the conversion of equal amounts of glucose to blood glucose by digestion, absorption and absorption in humans, which is responsive to the physiological properties of carbohydrates in food. The lower the GI value of the food, the less blood glucose excursions are caused, which is very advantageous for diabetic patients, because low GI foods contribute to blood glucose stabilization for diabetic patients.
The glycemic response of foods is influenced by many factors, mainly including the physical properties of the food, such as particle size, external shape, chemical composition, ingredient content, processing and cooking methods, etc. Although a plurality of influencing factors slow or prevent the conversion of available carbohydrates in food into glucose, so that the food is low in GI (glycemic index), and after the food is eaten, the blood sugar is slowly raised and lowered, thereby being beneficial to stabilizing the blood sugar; the prior related documents show that the high protein and fat content can reduce the blood sugar reaction of human bodies; the dietary fiber can effectively delay the digestion and absorption rate of food.
The dietary structure of Asians is mainly starch, so starting with the activity of key enzyme in controlling the sugar metabolism of the organism, the enzyme inhibitor is adopted to limit the absorption of carbohydrate, and the food has obvious effects of reducing blood sugar, blood fat and weight of specific people. For example, extracts from navy beans contain highly active alpha-amylase inhibitors, the chemical component of which is a complex glycoprotein. The alpha-amylase inhibitor is a novel diabetes mellitus treatment drug, takes an amylase which is a key enzyme of human carbohydrate metabolism as an action target, and reduces the digestion and absorption of carbohydrates in food and the lipogenesis by inhibiting the biological activity of the amylase, thereby playing the roles of reducing blood sugar, blood fat and weight. Compared with other products for reducing blood sugar and losing weight, the health-care food has the characteristics of safety, no toxicity and good tolerance, and is particularly suitable for long-term use to achieve the effects of prevention and treatment. L-arabinose inhibits enzymes which hydrolyze disaccharides, and thus inhibits elevation of blood glucose levels caused by sucrose intake (which is decomposed into glucose and fructose by the action of sucrase in the small intestine and absorbed); meanwhile, due to the inhibition effect of L-arabinose on disaccharide hydrolase, sucrose which is not decomposed in the small intestine is decomposed by microorganisms in the large intestine to generate a large amount of organic acid which has an inhibition effect on fat synthesis by the liver. Therefore, the L-arabinose can inhibit the accumulation of body fat, and can be used for preventing and treating diseases such as obesity, hypertension, hyperlipidemia and the like.
It is known that the high intake of saturated fatty acid is the main cause of the rise of blood cholesterol, triacylglycerol and LDL-C, which causes the narrowing of artery lumen, the formation of atherosclerosis and the increase of the risk of coronary heart disease. Experimental research and clinical practice prove that the vegetable oil containing polyunsaturated fatty acid has good effect of reducing cholesterol in blood, and can reduce the content of low-density lipoprotein (LDL) and very low-density lipoprotein (VLDL) in blood, thereby reducing the prevalence rate of coronary heart disease. The biscuit is a food which is made of wheat flour as a main raw material, sugar, grease or other raw materials and is crisp or soft in taste through processes of size mixing, forming, baking and the like. The protein content is 4-12%, the dietary fiber content is basically zero, the sweet cookies are rich in starch substances and added with white granulated sugar, the GI value of the sweet cookies is up to 77, and the sweet cookies belong to high-GI-value foods. Meanwhile, in the production and processing process of the biscuit, in order to obtain excellent processing performance, the shortening oil has high melting point, high content of long-chain fatty acid and high content of saturated fatty acid which is 45 to 60 percent, and is very unfavorable for human health.
Therefore, an industrial mass production method which has a low Glycemic Index (GI) and uses nutritional meal replacement biscuits rich in medium-chain fatty acids and high-unsaturated fatty acid shortening and adopts a proper technical scheme to solve the production problem according to the properties of raw materials is needed.

Alpha-amylase inhibitors and L-arabinose have synergistic effects, one inhibiting starch hydrolysis and one inhibiting sucrose hydrolysis. By coordinating the physiological action of the alpha-amylase inhibitor and the L-arabinose, the absorption of the human body to the carbohydrate can be greatly reduced, thereby having better effect on preventing the blood sugar rise and the fat accumulation of the human body caused by excessive intake of the carbohydrate and the metabolic syndrome caused by the blood sugar rise and the fat accumulation. Fat is an important ingredient of food, and is an important nutrient for human body. Different oils and fats are digested differently in vivo. Fatty acids are classified into medium-chain fatty acids, which are typically 8, 10,12 carbon medium-chain fatty acids, and long-chain fatty acids, which are fatty acids with more than 12 carbons. The long-chain fatty acid is emulsified in bile in intestinal tracts, and is hydrolyzed into fatty acid and diglyceride by lipase, and the fatty acid and the diglyceride enter blood after passing through a lymphatic system to be utilized by various tissues of a body, so that the speed of providing energy is low, the generated satiety is slow, the food intake is increased, the energy intake is increased, and the weight control is not facilitated. The medium-chain fatty acid is digested and then directly enters blood, enters liver and participates in fat metabolism, so that energy is rapidly provided for human bodies, and satiety is immediately provided; medium-and long-chain fatty acid edible oil (MLCT) is a new resource food in 2012, and clinical reports prove that the consumption of the Medium-and long-chain fatty acid edible oil (MLCT) group and the consumption of the long-chain fatty acid edible oil (LCT) group can reduce the blood triglyceride level and the body fat quality of the male hypertriglyceridemia patients. Therefore, the proportion of the medium-long chain fatty acid in the grease is necessary to be reasonably matched.
According to the invention, a product formula with high protein and high dietary fiber and reasonable oil content is adopted, and enzyme inhibitors such as white kidney bean extract, L-arabinose and the like are added, so that the biscuit has the characteristic of high nutritional density, and compared with biscuits in the existing market (about 10% of protein, 25% of fat, almost no dietary fiber and 65% of carbohydrate), the protein content is increased to 25-35 g/100g, which is more than 2.5 times that of conventional biscuits; the dietary fiber content is 10-15g/100g and almost none of the conventional biscuits; the oil content is controlled to be 15-20 g/100g of fat content, and the carbohydrate content is controlled to be 30-40g/100 g; after the white kidney bean extract and the L-arabinose are added, the GI value of the biscuit is 43, while the GI value of the conventional biscuit is up to 77 and is reduced by 34, and the biscuit belongs to low-GI food.
The special shortening is adopted and is rich in MLCT and unsaturated fatty acid, wherein the long carbon chain saturated fatty acid accounts for 30-40%, the medium carbon chain fatty acid accounts for 20-30%, the monounsaturated fatty acid accounts for 30-35%, the diunsaturated fatty acid accounts for 5-10%, and the traditional baked shortening accounts for 50-60% of the long chain saturated fatty acid. The proportion of the medium-chain fatty acid and the long-chain fatty acid in the grease is reasonably matched, the content of the unsaturated fatty acid is increased, and the health of a human body is facilitated. The invention adopts reasonable design of the proportion of the leavening agent, designs the leavening process according to the characteristics of the grease, optimizes the shape of the product and optimizes the process of low-temperature slow baking, solves the problems of no dry baking, inconsistent color inside and outside the cake body, loose cake body, serious damage after slight collision and the like in the production of high-protein high-dietary fiber biscuits by using the highly unsaturated shortening added with the MLCT, and realizes the industrialized mass production with high yield.
The invention aims to solve the health risks caused by excessively high GI value and excessively high proportion of saturated long-chain fatty acid of biscuits in the prior art, and provides a low Glycemic Index (GI) and a preparation method of a nutritional biscuit and a low production loss by applying shortening rich in medium-chain and highly unsaturated fatty acid through elaborately designing a nutritional formula and a technical scheme. The example product produced by the method has a GI value of 43 through clinical tests of a third party organization, belongs to low GI food, is particularly added with special grease MLCT, reasonably matches the proportion of medium-long chain fatty acid, has the content of saturated fatty acid accounting for less than 40 percent of the whole grease, and reduces the influence of the saturated fatty acid in the food on health.
The biscuit prepared by the invention has the characteristic of high nutritional density, the protein content is 25-35 g/100g, the fat content is 14-20 g/100g, the dietary fiber is 9-15g/100g, the carbohydrate is 30-40g/100g, and nutrient enhancers such as minerals and vitamins are added, so that the nutritional characteristics of the biscuit are enhanced. The proportion of the leavening agent, the leavening process, the product shape and the baking process are reasonably designed, the problems of no drying of baking, inconsistent color inside and outside the biscuit body, loose biscuit body, serious damage after slight collision and the like in the production of high-protein high-dietary fiber biscuits by using the high-unsaturated shortening added with the MLCT are solved, and the high-yield industrial mass production is realized.
According to the biscuit prepared by the formula of the biscuit, the ratio of polydextrose (soluble dietary fiber) to soybean dietary fiber (insoluble dietary fiber) is 3.5-5: 1, and multiple tests prove that the surface of the baked biscuit is smoother, has no cracks, and has small difference between the water content inside and outside the biscuit body and similar color; 2% of stachyose is added, and the stachyose can effectively promote the proliferation of intestinal probiotics by being matched with dietary fibers; the shortening content is controlled to be 14-20 g/100g, and shortening rich in medium-long chain fatty acid and high unsaturated fatty acid is adopted. The medium-chain (C8, C10 and C12) fatty acid content of the shortening accounts for 20-30% of the whole fat, the saturated fatty acid content is less than or equal to 40%, the influence of the saturated fatty acid in food on health is reduced, the solid oil content (SFC) of the shortening at different temperatures is shown in figure 1, the shortening needs to be kept at 20 ℃ for 24 hours when in use, the stable solid oil content and the original crystal form in the shortening are ensured, and the oil and the mixture can be effectively controlled to reach the specified 0.85-0.95 g/cm after being developed3Thereby ensuring the stability of the product; different enzyme inhibitors such as white kidney bean extract and L-arabinose are added in an amount of 0.3-0.8% respectively, so that the conversion of carbohydrates into glucose can be effectively slowed down.
The schematic diagram of the biscuit body prepared by the invention is shown in figure 2, when the biscuit body is baked, the water dispersion area and the dispersion distance of the biscuit body during baking are effectively increased, the water content inside and outside the baked biscuit is consistent, and the color is uniform; the baking process of low-temperature slow baking is adopted, the temperature can float up and down by 5-10 ℃ according to the conditions, the product yield is greatly improved, the conditions that the baking of the product is not dry, the difference of the water inside and outside the cake body is large and the color is not uniform due to the increase of the water absorption caused by adding high protein and high dietary fiber are prevented, and the baking temperature is low, the heat transfer speed is low, the expanding agent generates CO when heated2,NH3The rate is reduced, the cracking of the biscuit is reduced, the biscuit body is more complete and not easy to break, and the production and the transmission are realizedThe damage caused by medium and slight impact is greatly improved, and the product yield is greatly improved.
In summary, aiming at health risks caused by excessively high GI value of the biscuit, high saturated fatty acid and excessively high proportion of long-chain fatty acid and low GI value, the contents of protein and dietary fiber are increased, and the health risks can be effectively avoided by adopting medium-long-chain fatty acid and special shortening rich in high unsaturated fatty acid; however, in production, the shape of the biscuit dough with high protein and high dietary fiber is changed greatly, the biscuit dough is difficult to form, and the problems of high moisture in the baked biscuit, scorched surface and the like occur due to high water absorption of the dietary fiber, and aiming at the problems, a unique hollow circular cake shape is designed to facilitate the area of moisture diffusion and accelerate the moisture diffusion, and meanwhile, due to the change of the shape of the biscuit dough, the surface crack is easy to occur in baking, the internal structure is rough, and the taste is poor. Meanwhile, as the shortening rich in medium-long chain fatty acid and high unsaturated fatty acid is adopted, the melting point is low, the processing performance is greatly changed, the stirring and foaming degree in production is not enough, the product breakage rate is high, and the loss is large. Finally, for the sake of nutritional comprehensiveness, it is also necessary to add the prebiotics stachyose and minerals: calcium, iron, zinc and vitamin A, D, B1、B2、B6、Nicotinic acid and folic acid.
It should be noted that the above-mentioned embodiments are only for illustrating the technical solutions of the present invention and not for limiting, and although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that modifications or equivalent substitutions may be made on the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, which should be covered by the claims of the present invention.
