Drawings
Fig. 1 is a flow chart of an embodiment of the method for making the low GI steamed bread of the present invention.
The implementation, functional features and advantages of the objects of the present invention will be further explained with reference to the accompanying drawings.
Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The invention provides a method for making low GI steamed bread.
Referring to fig. 1, in the present invention, the method for making the low GI steamed bread comprises the following steps:
step S1, grinding 3-6 parts of Chinese yam, 2-5 parts of pearl barley and 2-5 parts of gordon euryale seed into powder, and sieving by a 60-100-mesh filter screen to separate coarse powder and fine powder. The yam is rich in yam polysaccharide, and related documents show that the yam polysaccharide can directly or indirectly improve the sugar metabolism or the activity of key enzyme; therefore, the Chinese yam polysaccharide has a certain treatment effect on type 2 diabetes (the reference document: Yang hongli and the like, the influence of the Chinese yam polysaccharide on the activity of HKSH and MTH of a type 2 diabetes rat is the university report of Liaoning traditional Chinese medicine, 2010, 12). Coix seed contains Coix seed polysaccharide, and related documents show that Coix seed polysaccharide has the effects of inhibiting hepatic glycogenolysis, myoglycogenolysis and gluconeogenesis, so as to achieve the purpose of reducing blood sugar level (reference document: Xucatahui, etc., research on separation and extraction of Coix seed polysaccharide and blood sugar reduction thereof, third-force medical university report, 2000, 6). The gorgon fruit extract has certain effect of reducing blood sugar for patients with diabetes (reference documents: Yangjiaolong, clinical research of the blood sugar reducing effect of gorgon fruit, clinical research of traditional Chinese medicine, 2014, 34). The Chinese yam, the coix seed and the gorgon fruit are ground into powder, the drug effect can be better exerted, in the subsequent steps, the fine powder is blended into the steamed bun dough to be directly eaten, the digestion and absorption can be better, and the coarse powder is boiled with water, so that the waste is avoided. In this step, the parts of chinese yam, seed of job' S tears and gorgon fruit are parts by weight, and concrete weight can be adjusted as required in actual operation, and the size of filter screen also can be selected as actual need, and in an optional embodiment, step S1 specifically is: grinding 4.78 parts of Chinese yam, 3.18 parts of pearl barley and 3.18 parts of gordon euryale seed into powder, and sieving by a 80-mesh filter screen to separate coarse powder from fine powder.
Step S2, adding 30-60 parts of water into 3-6 parts of rhizoma polygonati, 3-6 parts of radix puerariae, 3-6 parts of medlar, 3-6 parts of corn stigma, 0.5-1.5 parts of radix polygonati officinalis, 0.5-1.5 parts of flos sophorae, 0.5-1.5 parts of folium mori and the coarse powder, decocting, and filtering to obtain filtrate for later use. Modern pharmacological research shows that the rhizoma polygonati decoction has the effect of reducing blood sugar and blood fat for experimental diabetes and hyperlipidemia of rabbits (reference documents: rhizoma polygonati pharmacological action research progress such as humin, wangqin and Zhongxiandong and clinical application thereof, Guangdong, pharmacology 2005, 1(5) 68). In the research on the radix puerariae, the radix puerariae is found to be capable of effectively reducing the blood sugar of diabetic rats, reducing the formation of serum glycosylation end products and inhibiting the formation of aortic non-enzymatic glycation of the diabetic rats so as to reduce the blood sugar (the reference: Wangshilong et al, the blood sugar reducing effect of the radix puerariae, health research of Chinese and foreign women, 2015, 15). The corn stigma water decoction can obviously reduce the blood sugar of a alloxan diabetic mouse, and the blood sugar reducing effect of 30g of the corn stigma water decoction is similar to that of 100mg of hypoglycemic agent. The corn stigma decoction has the function of resisting the blood sugar rise of adrenal gland, and the action strength of large and medium dose groups is superior to that of 2.5mg for lowering blood sugar. The corn stigma water decoction has no obvious influence on the blood sugar of normal animals. Therefore, the corn stigma decoction can be presumed to have the function of biguanide hypoglycemic drugs. (reference: Liwei, Experimental study of corn stigma for lowering blood sugar, Chinese herbal medicine, 1995, 26). The hypoglycemic effect and the serum insulin (lm) level of the wolfberry are improved by repairing islet cells and promoting the regeneration function of islet B cells (reference: Zhaoyao et al. study on hypoglycemic effect of wolfberry and polysaccharides thereof, medical information 2011, 24 (8)). Yuzhu as a yin-nourishing drug is commonly used in the traditional Chinese medicine compound for treating diabetes, and clinical test results also prove that the contained Yuzhu saponin has the function of reducing blood sugar (reference documents: Guo Changrun et al, Yuzhu total saponin blood sugar reducing function laboratory research, Strong pharmaceutical journal Vol 23No, 42011). The rutin component in the sophora japonica can effectively improve capillary vessels and keep the original resistance, so that the traditional Chinese medicine sophora japonica can effectively treat hypertension, diabetes and the like (reference document: Guo Zhijin, research on the pharmacological action and processing of the traditional Chinese medicine sophora japonica, wisdom health, 2018, 1). The mulberry leaves have certain blood sugar reducing capability, and the mechanism of the blood sugar reducing function of the mulberry leaves is probably related to the generation of free radicals generated by antioxidant active ingredients of the mulberry leaves, the acceleration of the elimination of the free radicals and the secretion of insulin (reference documents: Junzhao, etc., the blood sugar reducing and blood fat reducing functions of mulberry leaf polysaccharide, Tianjin traditional Chinese medicine, 2004 and 21). The decoction obtained by decocting rhizoma polygonati, radix puerariae, medlar, corn stigma, radix polygonati officinalis, flos sophorae, folium mori and coarse powder together in the step has the function of reducing blood sugar, has a certain treatment effect on diabetes, and can be eaten as food. The decoction time is 20-60 minutes, the specific selection can be carried out according to the actual situation, as long as the effective components in the raw materials can be fully decocted into the traditional Chinese medicine water, the obtained traditional Chinese medicine water replaces clear water and flour in the subsequent steps, the drug effect of the traditional Chinese medicine can be fully exerted, and the effect of reducing blood sugar is achieved. In an alternative embodiment, the operation of step S2 may specifically be: 4.78 parts of rhizoma polygonati, 4.78 parts of kudzuvine root, 4.78 parts of medlar, 4.78 parts of corn stigma, 0.96 part of fragrant solomonseal rhizome, 0.96 part of sophora flower, 0.96 part of mulberry leaf and the coarse powder are added with 45 parts of water to be decocted and filtered, and the filtrate is taken for standby.
The dietary fiber.
And step S4, performing dough kneading operation after the dough is fermented, and dividing the dough into a plurality of steamed bun blanks after the dough kneading operation is completed. Kneading for 5-6 times with a dough kneading machine to remove gas from dough, and kneading to obtain fine dough with smooth surface and uniform color to avoid bubbles on the surface of steamed bread. After the dough is kneaded, the dough is quantitatively divided into standard square steamed bun blanks with the weight of 75g, and the blanks are properly shaped, so that the steamed bun products keep upright and full in appearance.
And step S5, proofing the steamed bread blank in an environment with the temperature of 25-35 ℃ and the humidity of 75-95%. The leavening is better that the surface of the billet is soft and not sticky, and through the leavening process, the medicine and the flour generate a series of biochemical reactions, the volume is doubled more than once, and a stable appearance is formed.
And step S6, steaming the steamed bread blank to obtain the low-GI steamed bread. Steaming the mixture in a steaming cabinet for 20-25 minutes, keeping gas circulation in a container in the steaming process, ensuring the steaming temperature, keeping the container closed, and ensuring that the introduced steam pressure is not too high.
In order to facilitate preservation, cooling and packaging can be carried out, the packaging is carried out one by one after cooling for 20-30 minutes, and the product is refrigerated and stored.
According to the technical scheme, the grains and the traditional Chinese medicines with the blood sugar control function are selected as raw materials, the traditional Chinese medicines are ground or decocted, the obtained traditional Chinese medicine powder is added into the grains and the traditional Chinese medicine water to replace clear water and flour in the subsequent steps, various effective components can better treat patients, the traditional Chinese medicines are added into the low-GI steamed bread, the efficiency is not only improved, but also the functions of natural traditional Chinese medicine flavoring agents, pH regulators and preservatives are exerted, and the quality of the steamed bread is more stable.
