Description

Technical Field

[0001] The invention belongs to the field of health food processing, and particularly relates to a method for preparing a Bletilla striata stomach-nourishing health food. Background Art

[0002] Bletilla striata is the dried tuber of Bletilla striata (Thunb.) Reichb.f., an orchid plant. It is bitter, sweet, astringent, slightly cold, and has the effects of astringent hemostasis, swelling reduction and tissue regeneration. So far, more than 150 compounds have been isolated from Bletilla striata, mainly including compounds with structures such as polysaccharides, stilbenes, steroids, triterpenes and phenolic acids. Modern pharmacological activity studies have shown that Bletilla striata mainly has pharmacological activities such as promoting blood circulation and hemostasis, anti-cancer, anti-tumor, promoting wound healing, resisting pathogenic microorganisms, protecting mucosa, anti-ulcer, whitening and anti-oxidation, anti-aging, and immunomodulation.

[0003] In 2002, the Ministry of Health of China issued the "Notice on Further Standardizing the Management of Health Food Ingredients" (Weifajianfa

[2002] No. 51), which included Bletilla striata in the "List of Items that Can Be Used in Health Foods". At present, the products of Bletilla striata are mainly concentrated in the protection of gastrointestinal ulcers and hemostasis, whitening cosmetics and biological materials, etc. There are very few health foods with Bletilla striata as the main raw material. Using "Bletilla striata" as the keyword, searching on the official website of the Special Food Information Inquiry Platform of the State Administration for Market Regulation (http: / / ypzsx.gsxt.gov.cn / specificfood / # / food), only three products "Qidan Brand Sanqi Bletilla striata Capsules", "Weiweikang Brand Sanqi Bletilla striata Oral Liquid" and "Zhendong Wuhe Brand Huangqi Malt Bletilla striata Tablets" have been registered. Health products with Bletilla striata as raw materials have great research and development potential.

[0004] Baiji has a sticky texture and is not easy to digest. When taking Baiji, it is often ground into powder or combined with other digestive foods. Coix seed is rich in substances such as amylase and protease, which can promote gastrointestinal digestion and relieve symptoms such as indigestion. According to statistics, among the high-frequency medicinal flavors in prescriptions containing Baiji with the effect of tonifying the spleen and replenishing qi, coix seed ranks sixth with 8 appearances. Glutinous rice flour can increase the aroma, make the taste soft and sticky, and dilute the special smell of Baiji. In addition, both coix seed and glutinous rice are rich in dietary fiber, which can promote gastrointestinal motility. In addition to promoting digestion, they can also reduce blood lipids. Summary of the invention

[0005] The invention aims to provide a health-care food of Bletilla striata which has good taste, fragrant smell and stomach-nourishing effect.

[0006] To achieve the above purpose, the technical solution adopted by the present invention is as follows:

[0007] A method for preparing a Bletilla striata stomach nourishing health food, wherein the raw materials are composed of Bletilla striata, coix seed and glutinous rice; the preparation method comprises the following steps:

[0008] (1) Powdering of Bletilla striata gum: After the dried tubers of Bletilla striata are crushed and passed through a 20-mesh sieve, the Bletilla striata powder is mixed with purified water in a ratio of 1:10 to 20, the mixture is stirred evenly and allowed to stand, and then 10 to 20 parts of purified water are added and ultrasonic extraction is performed, the mixture is filtered and squeezed through gauze, and the filtrate is dried and ground to obtain Bletilla striata gum powder for later use;

[0009] (2) Pre-gelatinization: coix seed and glutinous rice are pre-gelatinized separately;

[0010] (3) Proportional mixing: The pre-gelatinized coix seeds and glutinous rice are respectively pulverized by an ultrafine grinder and passed through a 20-mesh sieve, and the white radish glue powder, coix seed powder and glutinous rice flour are mixed. The composition ratio of the white radish glue powder, coix seed powder and glutinous rice flour is 1-2:1-2:3-5 according to mass measurement. After mixing, stir evenly to obtain the white radish stomach-nourishing health food.

[0011] Furthermore, in step (1), the standing time is 30 min to 45 min; the ultrasonic extraction time is 30 min to 45 min, the power is 150 W, the frequency is 20 kHz, and the water bath temperature is 60°C.

[0012] Furthermore, in step (2), the pre-gelatinization treatment method is to put the seeds into a drum-type automatic stir-frying machine for frying, the frying temperature is 100-120° C., the frying time of coix seeds is 5-8 minutes, and the frying time of glutinous rice is 3-5 minutes.

[0013] Furthermore, in the Bletilla striata stomach nourishing health food described in step (3), the preferred ratio of Bletilla striata glue powder, Coix seed powder and glutinous rice flour is 1:1:4.

[0014] Beneficial Effects

[0015] The present invention provides a method for preparing a Bletilla striata stomach nourishing health food, which has the following beneficial effects:

[0016] 1. Bletilla striata is slightly cold in nature, bitter, sweet and astringent in taste. It enters the lung meridian, liver meridian and stomach meridian. It has the functions of astringent hemostasis, swelling reduction, muscle growth and lung tonification. It is often used in clinical treatment of internal and external bleeding, sprains, sores and other symptoms. It has been confirmed that it has a protective effect on the stomach, esophagus, oral cavity, intestinal mucosa, etc., reduces mucosal inflammation, improves local microcirculation, accelerates mucosal repair, condenses red blood cells, promotes ulcer healing, inhibits the growth of Helicobacter pylori, and has a good effect in treating peptic ulcers and preventing recurrence.

[0017] 2. Glutinous rice is warm in nature and sweet in taste. It belongs to the spleen meridian, stomach meridian and lung meridian. Eating glutinous rice in moderation can nourish the spleen and warm the stomach, and replenish the middle and benefit the qi. Glutinous rice contains a large amount of amylopectin, the content of which can reach 95%-100%. The glutinous rice starch is type A amylopectin. This chemical structure determines that after heating and gelatinization, glutinous rice has high viscoelasticity and ductility, and has a tight structure, can be stretched, and is chewy, but does not stick to teeth (easy to shear). It is in a highly soft gel state and shows good anti-aging ability.

[0018] 3. Coix seeds are slightly cold in nature, sweet and light in taste, belonging to the spleen, stomach and lung meridians, and have the effects and functions of diuresis and swelling, clearing away heat and detoxification, strengthening the spleen and digestion, cooling blood and stopping bleeding, and beautifying and nourishing the skin. The earliest monograph on the processing of coix seeds, "Leigong Paozhi Lun", records that "whenever (coix seeds) are used, boil them with 2 taels of glutinous rice, let the glutinous rice cook, remove the glutinous rice and use it. If it is boiled in salt soup, it can be processed in general." Reports on the pharmacological activities of coix seeds such as anti-tumor, analgesia and anti-inflammatory, regulating sugar and lipid metabolism, enhancing immunity, lowering blood pressure, anti-oxidation, anti-aging, and whitening have appeared one after another.

[0019] 4. The frying treatment in the preparation method will degrade macromolecular substances such as starch and protein in coix seeds and glutinous rice, promote the occurrence of caramelization reaction and Maillard reaction, and achieve the purpose of pre-gelatinization. The frying treatment can improve the texture, flavor and nutritional value of coix seeds and glutinous rice, thereby achieving the purpose of improving quality. DETAILED DESCRIPTION
