Description

Low-sugar weight-reducing coffee and preparation method thereof

The technical field is as follows: the invention belongs to a functional food and beverage formula technology and a preparation method thereof.

Background

In recent years, many foreign experts and scholars have conducted extensive and intensive studies on weight-reducing methods, and many effective methods have been proposed, and they are roughly classified into two types: a scientific diet weight-losing method, which achieves the purpose of losing weight by scientifically controlling daily diet; second, a physiological diet therapy is used to reduce weight by taking a diet according to the functional status of the body. Weight loss is achieved by a scientific method (best scientific diet). For people with obesity, even people with obesity-prone constitution, the vigorous and forceful obesity still remains a life habit. The proud flesh is not born and is in some cases, namely the following most fatteness life habits are seen: 1. snacks are continuously eaten after dinner, and people still eat overnight before sleeping. 2. No breakfast or very greasy breakfast. 3. The dining speed is very fast, and people often eat while watching television or going on a net. 4. The cola bottled fruit juice is very delicious when being eaten sweet fried food. 5. Almost never move, and also sit on the elevator from first floor to second floor. 6. The walking time is not more than 20 minutes per day. 7. In the dietary structure, much pasta and meat is eaten, but little vegetables and fruits are eaten. 8. Often stay up overnight. Unhealthy weight loss methods include the use of various weight-reducing drugs to try to prevent the increasingly fat stature, which is not only easy to damage the body and reduce weight rebound, but also serious and possibly damaging the life or endangering life. Moreover, due to the fact that the market of weight-reducing medicines is mixed and different in quality, the market of weight-reducing products is disordered, and shadow is formed on the weight reduction of people. Along with the popularization of the healthy green life concept, more and more people favor a natural weight-losing method, common natural weight-losing methods comprise healthy weight-losing exercises and natural healthy diet weight-losing, and weight-losing products comprising components without toxic and side effects such as L-carnitine and active ingredients such as pure natural traditional Chinese medicines, fruits, vegetables and herbaceous plants. It is primarily intended to reduce the absorption of lipid substances in food by the intestinal tract, control the intake of calories in the body and prevent the storage of new fats. The excessive fat is consumed by heat production, the metabolism rate of the fat is accelerated, the fat is converted into protein sugar, the balance of the original nutritional ingredients of the body is kept, the fat and the blood fat of the human body are adjusted, and the body is beautified and slimed. Obesity can cause various metabolic disorders and diseases, such as hyperlipidemia, impaired glucose tolerance, hyperinsulinemia, and hyperuricemia. Among obese people, hypertension, coronary heart disease, stroke, atherosclerosis, type 2 diabetes, gallstones and chronic cholecystitis, gout, osteoarthropathy, obstetric accidents, gynecological tumors, intestinal tumors and prostate cancer have high incidence, and obese people can also suffer from liver diseases because of accumulation of fat in the liver, so that fatty liver, also called fatty liver deformation, can occur, and cardiopulmonary insufficiency and sleep apnea syndrome can occur.

Disclosure of Invention

The invention aims to overcome the problems and provide the coffee which is efficient and safe and has the function of losing weight with low sugar. The functions of coffee, L-carnitine, inulin, lotus leaf, hawthorn, cassia seed, fructus cannabis, corn stigma and sucralose are effectively combined; the weight loss is effectively realized, the full spirit is kept, the hunger is not felt, and the natural weight loss effect is realized in the mind and physiology; the sucralose meeting the requirements of the national food safety standard can not increase the calorie while enriching the mouthfeel. The product is added without sugar, and has no pollution, no harm and natural health food, thereby achieving the natural weight-reducing effect. The invention also provides a preparation method of the composition. The invention is realized by the following technical scheme:

the low-sugar weight-reducing coffee comprises the following components in percentage by weight: 30 to 60 percent of coffee powder, 10 to 30 percent of skim milk powder, 10 to 30 percent of inulin, 0.6 to 3 percent of L-carnitine, 0.1 to 5 percent of lotus leaf, 0.1 to 5 percent of hawthorn, 0.1 to 5 percent of cassia seed, 0.1 to 5 percent of fructus cannabis, 0.1 to 5 percent of corn stigma and 0.01 to 1.0 percent of sucralose.

The low-sugar weight-reducing coffee is characterized in that raw materials for preparing the raw materials are as follows: the formula of the components by weight percentage is as follows: 30 to 60 percent of coffee powder, 10 to 30 percent of skim milk powder, 10 to 30 percent of inulin, 0.6 to 3 percent of L-carnitine, 0.1 to 5 percent of lotus leaf, 0.1 to 5 percent of hawthorn, 0.1 to 5 percent of cassia seed, 0.1 to 5 percent of fructus cannabis, 0.1 to 5 percent of corn stigma and 0.01 to 1.0 percent of sucralose.

The preparation method of the low-sugar weight-reducing coffee is characterized by comprising the following steps of:

(1) respectively preparing all the raw materials in corresponding parts by weight, and reserving a firewood bag for later use:

(2) putting coffee powder, skimmed milk powder, inulin, L-carnitine and sucralose into a container according to a corresponding proportion; stirring at high speed and mixing.

(3) Sieving and magnetically separating the mixed raw materials:

(4) sterilizing with microwave, and packaging.

(5) And (5) putting the semi-finished products into boxes, sealing, performing total inspection, and then boxing and warehousing.

The use method of the product comprises the following steps: the product is unpacked and led into a cup, and hot water is added and stirred evenly to be drunk.

The weight-losing principle of the invention is as follows: the invention does not add excessive heat without adding sucrose, and the main function of the invention is to transport fat to mitochondria for combustion through L-carnitine. Besides meeting the nutrition required by human body, inulin contains rich dietary fiber to reduce the absorption of lipid substances in food by intestinal tract, control the intake of human body calorie and prevent new fat storage. The excessive fat is consumed by heat production, the metabolism rate of the fat is accelerated, the fat is converted into protein sugar, the balance of the original nutritional ingredients of the body is kept, the fat and the blood fat of the human body are adjusted, and the body is beautified and slimed.

The raw materials adopted by the invention have the following effects:

coffee: coffee contains kahweol and cafestol, and has anticancer and antiinflammatory effects. Coffee can up-regulate the anti-toxic biochemical processes in the liver and protect the body from aflatoxins and other carcinogens. Coffee contains chlorogenic acid, which has been shown to promote glucose metabolism and increase insulin sensitivity, and to increase the utilization of blood glucose by muscle, thereby reducing the risk of diabetes in humans. The active ingredients in coffee can help to alleviate oxidative stress, i.e. the imbalance between free radicals and antioxidants. Caffeic acid in coffee can improve blood sugar utilization degree of muscle, and also contains components for promoting immune system and resisting inflammation. The caffeine is a xanthine alkaloid compound, is a central nerve stimulant, can temporarily drive drowsiness and restore energy, and is clinically used for treating neurasthenia and coma resuscitation.

And (3) skim milk powder: the defatted milk powder is prepared by removing fat from fresh milk and drying, and the fat can be reduced to about 1 percent, and the other changes are not large. The skimmed milk powder is milk white or light yellow, has mild Olibanum and sweet taste, and has no deterioration, scorched flavor or abnormal odor. The defatted milk powder is prepared by using milk as raw material, adding or not adding food nutrient reinforcer, defatting, concentrating and drying, and is a powdered product with protein not less than 34% of non-fat milk solid and fat not more than 2.0%, and is suitable for people with obesity and need of supplementing nutrients. The skimmed milk powder is beneficial for the elderly, infants with dyspepsia, and patients with diarrhea, gallbladder diseases, hyperlipidemia, chronic pancreatitis, etc.

Inulin: inulin is a reserve polysaccharide in plants, mainly comes from plants, and has been found in 36000 kinds, including 11 families of dicotyledonous plants such as Compositae, Campanulaceae and Gentianaceae, and 11 families of monocotyledonous plants such as Liliaceae and gramineae. For example, inulin is abundant in Jerusalem artichoke, tubers of chicory, root tuber of Paeonia suffruticosa (Dali chrysanthemum), and roots of Cirsium japonicum, wherein inulin content of Jerusalem artichoke is the highest. Controlling blood lipid intake of inulin can effectively reduce serum Total Cholesterol (TC) and low density lipoprotein cholesterol (LDL-C), increase high density lipoprotein/low density lipoprotein ratio, and improve blood lipid condition. Many dietary fibers reduce blood lipid levels by absorbing intestinal fat to form fat-fiber complexes that are carried out with the stool. Furthermore, inulin ferments itself to short chain fatty acids and lactate, which are regulators of liver metabolism, before it ends up in the intestine. Short chain fatty acids (acetate and propionate) are used as fuel in the blood, and propionate inhibits cholesterol synthesis. And (3) reducing blood sugar: inulin is a carbohydrate that does not cause an increase in urine glucose. It is not hydrolyzed to monosaccharides in the upper part of the intestinal tract and thus does not raise blood sugar levels and insulin content. Studies today show that the reduction in fasting plasma glucose is a result of short chain fatty acids produced by fermentation of fructooligosaccharides in the colon. And (3) promoting the absorption of minerals: the main mechanisms by which inulin promotes the absorption of mineral elements are: 1) short-chain fat generated by inulin fermentation in colon lightens crypts on the mucous membrane, increases crypt cells, increases absorption area, and develops cecal veins. 2) The pH of colon is reduced by acid generated by fermentation, so that the solubility and bioavailability of many minerals are improved, and especially, the short-chain fatty acid can stimulate the growth of colon mucosal cells and improve the absorption capacity of intestinal mucosa; 3) inulin can promote some microorganisms to secrete phytase, and phytase can release metal ions chelated with phytic acid to promote absorption of the phytase. 4) Some organic acids generated by fermentation can be chelated with metal ions to promote the absorption of the metal ions. Regulating intestinal microbial flora, improving intestinal health, and preventing constipation: inulin is a natural water-soluble dietary fiber, hardly hydrolyzed and digested by gastric acid, and is utilized only in the colon by beneficial microorganisms, thereby improving the intestinal environment. It has been found that the degree of proliferation of bifidobacteria depends on the number of primary bifidobacteria in the large intestine of humans, and that the effect of proliferation is significant when inulin is used when the number of primary bifidobacteria is reduced, and not significant when inulin is used when the number of primary bifidobacteria is increased. Secondly, after the inulin is ingested, the gastrointestinal peristalsis can be enhanced, the gastrointestinal function can be improved, the digestion and the appetite can be increased, and the organism immunity can be improved. Inhibiting the generation of toxic fermentation products, protecting the liver and preventing colon cancer: the food reaches colon after being digested and absorbed, under the action of intestinal saprophytic bacteria (Escherichia coli, Bacteroides and the like), a plurality of toxic metabolites (such as ammonia, nitrosamine, phenol, cresol, secondary bile acid and the like) can be generated, and short-chain fatty acid generated by fermenting inulin in the colon can lower the pH of the colon, inhibit the growth of saprophytic bacteria, reduce the generation of toxic products and reduce the stimulation of inulin to intestinal walls. As a series of metabolic activities of inulin can inhibit the generation of toxic substances, increase defecation frequency and weight, increase fecal acidity, accelerate the excretion of carcinogen, generate short-chain fatty acid with anticancer effect, and is beneficial to preventing colon cancer. The dietary fiber for preventing constipation and treating obesity can reduce the retention time of food in stomach and intestine, increase the amount of excrement, and effectively treat constipation. The weight reducing effect is to increase the viscosity of the contents and reduce the speed of food entering the small intestine from the stomach, thereby reducing hunger sensation and food intake. The inulin contains a small amount of 2-9 fructo-oligosaccharide, and research shows that the fructo-oligosaccharide can increase the expression of brain nerve cell trophic factors, has good protection effect on corticosterone-induced neuron damage, and has good antidepressant effect. The weight-losing effect is as follows: inulin can promote the absorption of vitamins and microelements by regulating the movement of intestines and stomach, so that the health is realized, the physical strength is sufficient, the consumption of internal energy is promoted in turn, and the purpose of losing weight is achieved. On the other hand, after inulin is ingested, blood sugar is reduced, blood sugar does not rise, insulin of pancreatic islets is not secreted, insulin is not secreted, glucose and the like are not stored in cells, so that the body is not fat. On the basis, when some exercises are properly done, part of fat can be burnt, and the purpose of slimming is achieved.

L-carnitine: l-carnitine (also known as L-carnitine or transliteration carnitine) is an amino-like acid for promoting fat to be converted into energy, and red meat is a main source of the L-carnitine and has no toxic or side effect on human bodies. Different types of diets already contain 5-100 mg of l-carnitine, but generally only 50 mg per day can be ingested by people from the diet, and less by vegetarians. The main physiological function of the L-carnitine is to promote fat to be converted into an energy test structure, and the L-carnitine can reduce body fat and weight without reducing moisture and muscle when being taken.

L-carnitine is regulated by national food additive health standard GB2760-1996 to be a food nutrition enhancer, which can be applied to chewable tablets, drinking fluid, capsules, milk powder, milk drinks and the like, and can be used as one of main components of weight-reducing nutritional foods, L-carnitine mainly comes from animals in the diet, and the content of plants is very small, fasting, vegetarian diet, vigorous exercise, obesity, infertility, male sterility, infants eating carnitine-unfortified formulas and other people are prone to lack of carnitine, low in lysine, vitamin and iron content in the diet also leads to carnitine deficiency, many patients such as heart disease, hyperlipidemia, nephropathy, liver cirrhosis, malnutrition, low in thyroid function, certain muscle and neurological diseases and the like, the carnitine level is generally low, L-carnitine supplementation mainly depends on exogenous carnitine supplementation, and the importance of L-carnitine supplementation is not sub-important to vitamin and mineral supplementation of L-carnitine, and the L-fatty acid metabolism is not less important to supplement the carbohydrate, and the fat metabolism is not increased to the fat metabolism, but the fat metabolism is not increased to a little if the L-carnitine metabolism is not increased, the fat metabolism is not increased in the weight-reducing process, the fat metabolism is not increased by the dietary process of fat metabolism.

Sucralose: sucralose (TGS), a novel sucralose developed by tite & ly, a university of london and patented in 1976. Is the only functional sucralose taking sucrose as the raw material, the original trade name is Splenda, and the sweetness can reach 600 times of that of sucrose.
