Abstract

The invention relates to a selenium-rich low-cholesterol duck egg and a production method thereof, belonging to the production field of healthcare functional eggs. In the invention, lactobacillus acidophilus and candida utilis are used as strains; the culture medium contains 0.5-2% of yeast extract paste and 0.5-2% of glucose; and the strains are inoculated in the culture medium containing sodium selenite to culture for 30-40 hours. The obtained selenium-rich probiotic culture solution is added to the corn bean pulp type basic ration to feed the laying duck; and one month later, the selenium-rich low-cholesterol duck eggs are obtained. While providing relatively comprehensive nutrition, the selenium-rich low-cholesterol duck egg produced by the invention plays the function of supplementing selenium, has the advantage of low cholesterol, has wide healthcare functions, and is particularly important in preventing cardiovascular diseases of human bodies.

Description

technical field [0001] The invention belongs to the technical field of production of health-care functional eggs, in particular to a selenium-enriched low-cholesterol duck egg and a production method thereof. technical background [0002] Poultry eggs have high nutritional value, and their nutritional composition is relatively comprehensive and balanced. They are rich in protein, various unsaturated fatty acids, lecithin, cholesterol, vitamins and trace elements, etc., and are easy to digest and absorb. nutritious food. The protein content in poultry eggs is about 13%-15%, which is slightly lower than that of lean meat, but its amino acid composition and proportion are closest to human protein, and egg yolk protein is rich in amino acids beneficial to human body, such as leucine, isocyanin Amino acids, lysine, methionine, threonine, tryptophan, valine, etc. Therefore, its protein utilization rate is the highest, 94% for whole eggs and 96% for egg yolks, ranking first among...
