Technical Field
The invention relates to the technical field of food processing, in particular to high-protein high-dietary-fiber low-energy fermented rice and a preparation method thereof.
Background
The protein is an important nutrient component required by a human body, has the characteristics of low calorie, low fat and low cholesterol, and is a favorite of infants, old people, athletes, postoperative patients and weight-losing people. In particular, the proteolytic polypeptide not only has nutrition, but also has certain physiological activities, such as antioxidation, blood fat and cholesterol reduction, blood pressure reduction, liver protection, body tissue repair, immunoregulation and anti-fatigue effects.
Dietary fiber is a special carbohydrate, which cannot be digested, decomposed and absorbed by human body, and is called 'seventh major nutrient' of human beings. Scientific research shows that the dietary fiber has strong water absorption, promotes gastrointestinal peristalsis to bring excessive nutrition out of the body, particularly has huge adsorption groups, and can dilute and accelerate the removal of carcinogenic substances and toxic substances in food, protect the health of digestive tracts and prevent colon cancer. Meanwhile, the dietary fiber can increase satiety and speed of people to excrete cholesterol, and can control blood sugar and cholesterol in blood to reasonable levels.
With the development of technology, food processing is more and more refined, and the eating habits of high sugar and high fat bring a series of problems to the health of people, such as constipation, obesity, arteriosclerosis, cardiovascular and cerebrovascular diseases, diabetes and other modern 'civilization diseases', and the health of people is seriously threatened. Thus, a high protein, high dietary fiber, low energy food is an effective solution to circumvent current high sugar, high lipid diets.
Disclosure of Invention

In order to achieve the above objects, the present invention provides a method for preparing high protein, high dietary fiber, low energy fermented rice, comprising the steps of,
(1) saccharifying glutinous rice: soaking fresh glutinous rice in water, steaming, cooling, inoculating Rhizopus powder 0.4-0.6 wt% of glutinous rice at 30 deg.C, and saccharifying for 2-3 days to obtain saccharified glutinous rice with sugar juice filtered out.
(2) Fermenting and saccharifying glutinous rice: inoculating 0.4-0.8% of saccharomyces cerevisiae and 0.2-0.4% of esterified red yeast in percentage by mass of the saccharified glutinous rice, fermenting for 1-2 days at 26-28 ℃, and filtering to obtain the sugar-free fermented rice.
(3) Preparing fermented rice: the sugar-free fermented rice is dried by hot air at 70-90 ℃ to prepare the fermented rice, wherein the total protein of the fermented rice is 600g/kg, and the total dietary fiber of the fermented rice is 220 g/kg.
Further, in the step (1), the fresh glutinous rice is added with water with the mass ratio of 1.5 times to be soaked for 3 hours and then steamed.
Further, in the step (2), the saccharified glutinous rice is fermented by anaerobic fermentation to convert sugar into alcohol.
Further, in the step (3), the moisture content of the dried fermented rice is lower than 100 g/kg.
Therefore, the preparation method of the high-protein, high-dietary-fiber and low-energy fermented rice has the following beneficial effects:
1. the invention adopts rhizopus to saccharify glutinous rice starch, and simultaneously hydrolyzes protein into polypeptide and amino acid, thereby increasing the polypeptide in the fermented rice.
2. The invention consumes residual sugar of the saccharified glutinous rice through anaerobic fermentation of the saccharomyces cerevisiae and the esterified red yeast rice, reduces the energy of rice, and increases thalli, metabolic nutrient substances and fermentation fragrance.
3. The invention adopts a biological fermentation method to efficiently remove starch and sugar in the rice, retains dietary fiber in the rice, and obtains healthier high dietary fiber fermented rice compared with the traditional acid-base extraction mode.
