Absorption and metabolism of bee pollen

2015-02-06 classification: efficacy effect 0 people commented on the long history of human understanding and application of bee pollen China is the first country in the world to recognize and apply bee pollen With the development of science and technology, the research on bee pollen is more and more in-depth It is more and more clear that bee pollen can not only provide a variety of nutrients for human body, but also provide rich raw materials for the growth and repair of tissue cells At the same time, the nutrients and bioactive substances in bee pollen have different processes for the physiological functions of the body and the biological activities of various organ systems Regulation of degree In view of the fact that human digestive fluid can't destroy the cell wall of pollen, it has become a very concerned problem for pollen food research, producers and consumers that whether the nutrients of non broken pollen can be digested and absorbed by human body and how much it can be digested and absorbed A large number of studies have been carried out at home and abroad The results show that the nutrients of unbroken pollen can also be digested and absorbed by human body The Schmidt brothers, Department of insects, University of Arizona, USA, fed three groups of developing young mice with turnip bean pollen, whole egg and milk protein as the only source of protein under the condition of the same other ingredients in the feed, and measured their digestibility of pollen The results showed that the mouse could not digest the outer wall of the pollen, but at least absorbed 8q% of the protein in the pollen The Department of biology of Hangzhou University fed rape pollen to macaque, and then analyzed the undigested amino acids of pollen and fecal tissue The results showed that the absorption rate of total amino acids in non broken pollen was 83.9.4%, and 85.85% in broken pollen, the difference was only about 2% In order to understand whether pollen can be digested and utilized by animals, some researchers have conducted animal feeding experiments with pollen In the first 60 days, 17% more eggs were produced by adding pollen to the feed of hens, and the yolk quality was increased, and the color was better; histological observation showed that the diameter of primary egg increased, and the level of gonadotropin in the blood increased Costantini et al Carried out experiments with baby chickens The results showed that pollen could increase the body weight of both male and female chickens, and the weight of female chickens was more obvious than that of male chickens Salajan et al Used 40 piglets as experiment, the results showed that adding 2% - 4% pollen to feed can significantly increase the weight of piglets Papa et al Added 40 g of pollen in the feed of calves every day, and by the age of 2 years, the average weight of the control group was 444 kg; the average weight of the feed group added pollen was 495 kg, with significant weight gain effect.
