Processing method of low-purine bean product

Abstract

The invention discloses a processing method of a low-purine bean product. The processing method comprises the steps of: when soybean is adopted as a raw material to carry out processing of the bean product, firstly making the dry soybean into soybean milk, putting the dry soybean into water for soaking when the soybean milk is made, soaking according to that the ratio of the dry soybean to the water is (1g-2g): (10mL-20mL) and then grinding into soybean milk; then utilizing an acid salt (CaCl2) to treat the soybean milk, wherein the treatment method is as follows: adding 0.5-0.8mol of CaCl2 in 1mL of soybean milk, stirring the soybean milk continuously, heating to 80-100 DEG C, carrying out constant-temperature reaction treatment for 0.5-1 hour, and then obtaining a low-purine soybean milk product; or manufacturing the low-purine soybean milk product into bean curds according to the traditional bean curd manufacturing technique, thus obtaining low-purine bean curd products. Due to adoption of the processing method, 47-50% of guanine and 40-42% of adenine in the soybean milk can be removed. The invention is a method for removing purines in the bean products in a stable, long-acting, safe, nontoxic, economic and convenient manner.

Description

Technical field: [0001] The invention relates to a processing method of a low-purine soybean product, and belongs to the technical field of soybean product processing. Background technique: [0002] Soybeans ( Glycine max(L.) Merr. ) is an annual herb, native to China. Soybean production in China is divided into five main producing areas: spring soybean area dominated by the three northeastern provinces, summer soybean area in the Huanghuai River Basin, spring and summer soybean area in the Yangtze River Basin, autumn soybean area in southern Jiangnan provinces, Guangdong, Guangxi and southern Yunnan Soybean multi-ripening area. Among them, the spring-sown soybeans in Northeast my country and the summer-sown soybeans in Huanghuai are the two areas with the largest soybean planting area and highest yield in China. ​​ [0003] Soybeans are rich in vegetable protein, V E As well as isoflavones, etc., can enhance the physique and the body's disease resistance, has the functi...

AI Technical Summary

Problems solved by technology

Although soybean processed products are rich in nutrition, the content of purine contained in soybean products processed by the existing technology is still relatively high, so it is not suitable for patients with gout to eat

After determination, the main purine substances in soybeans produced in the market are guanine and adenine, wherein the content of guanine is about 48.0mg / 100g (dry weight.), and the content of adenine is about 15.74mg / 100g (dry weight. heavy), and the existing soy product processing technology cannot reduce or reduce the purine content in beans

Therefore, the processing technology of existing bean product is still not ideal enough, can not satisfy people's needs
