Description

[0001] ‌Technology Field‌

[0002] The invention relates to the field of food processing, and in particular to a recycled rice product with controlled three highs and a preparation method thereof.

[0003] ‌Background Technology‌

[0004] Regenerated rice is also called composite nutritious rice, recombinant rice, and artificial rice. It is mainly made of brown rice, or a certain proportion of other grains, potatoes, vegetables and other raw materials are added. After mixing, crushing, conditioning, granulation, drying, cooling and other steps, it is made into a safe, natural, nutritionally balanced regenerated rice with the same appearance and cooking method as ordinary rice. At present, in order to improve insufficient nutrition intake and nutritional imbalance, there are also various types of regenerated rice on the market, such as grain rice, fruit and vegetable rice, and nutritionally fortified regenerated rice. These regenerated rice are rich in nutrition but have a high degree of gelatinization. After consumption, the human body can digest it completely within 1-1.5 hours. Although it improves the digestion efficiency and nutrient absorption efficiency, it causes the blood sugar content of the human body to rise sharply in a short period of time, which is very unfriendly to people with three highs.

[0005] White kidney bean powder and Indian finger millet are rich in α-amylase inhibitors. Yang Ning found that taking white kidney bean extract before meals can improve postprandial blood sugar (Journal of Medical Research, 2020, 49(4): 24−28.), and Sivakumar S studied the inhibitory effect of amylase inhibitors from Indian finger millet on α-amylase (Pesticide Biochemistry and Physiology, 2006, 85(3): 155-160.).

[0006] In view of the fact that the extracts of white kidney bean powder and Indian millet have an improving effect on postprandial blood sugar, new foods with natural amylase inhibitors as both medicinal and edible ingredients have appeared on the market. For example: Chinese patent application number: CN201710397759.1 discloses a composite nutritious rice composed of broken rice powder, white kidney bean powder, etc., which has a blood sugar lowering effect; white kidney bean powder produced by Shaanxi Bolin Biological, white kidney bean tablet candy produced by Shandong Zhushi Pharmaceutical, and white kidney bean meal replacement tablets produced by Henan Baizhitang Pharmaceutical, etc.

[0007] Recycled rice has become a common concern as it can meet nutritional needs without causing health problems related to the three highs. Summary of the invention
