Selenium-rich high-dietary-fiber recombinant rice and processing method thereof

Abstract

The invention provides a selenium-rich high-dietary-fiber recombinant rice and a processing method thereof. The processing method comprises the following steps: uniformly mixing the following raw material powder in parts by weight, adding water which accounts for 20-35% of the weight of the mixed raw material powder for hardening and tempering, putting the mixed raw material powder into a double-screw extrusion granulator for low-temperature extrusion to form rice grains, and carrying out air draft drying at 35-65 DEG C for 1-2 hours to obtain the selenium-rich high-dietary-fiber recombinant rice with the dietary fiber content of 6-15% and the selenium content range of 18-30mu g/100g. The mixed raw material powder is prepared from the following raw material powder in percentage by weight: rice flour, whole grain powder, medicinal and edible food powder, bean powder, potato powder, dietary fiber powder and a selenium-enriched oyster mushroom enzyme hydrolysis extract. The selenium-rich high-dietary-fiber reprocessed rice can well solve the problem of a supplement source of selenium element for people in selenium-deficient areas, and can be used as a supplement source of dietary fibers for people with insufficient dietary fiber intake, so as to achieve the purpose of supplementing the dietary fibers.

Description

technical field [0001] The invention relates to the field of food processing, in particular to a selenium-enriched high dietary fiber recombined rice and a processing method thereof. Background technique [0002] Along with the demand for nutritional balance, the supplementation of trace elements has also received widespread attention, and more and more people have begun to scientifically supplement the trace elements needed by the body. Selenium is one of the essential trace elements for the human body. It is a natural antidote for some heavy metal elements. It can effectively improve the immune function of the body and play an important role in preventing and fighting cancer. Selenium is an important substance for anti-oxidation and anti-aging in the human body. The occurrence of many diseases is related to the low intake of selenium. Appropriately increasing the intake of selenium in the diet can improve the body's resistance to certain diseases. Studies have shown that...

Selenium-enriched Pleurotus ostreatus extract is extracted from selenium-enriched Pleurotus ostreatus (Pleurotus ostreatus (dry base) selenium content ≥ 0.15μg / g is called selenium-enriched oyster mushroom), which further increases the nutritional and health value of Pleurotus ostreatus polypeptide, is A safe and efficient organic selenium health product, but there are few studies on the extraction of selenium-enriched edible fungi, especially for the extraction of selenium-enriched oyster mushrooms, which is to reduce the loss of selenium in the extraction process on the one hand, and on the other hand. Ensure that the structure and biological activity of organic selenium polypeptides and organic selenium polysaccharides are not damaged
