Instant yolk oligopeptide-phosphatide type DHA double-effect dietary supplement and preparation method thereof

Abstract

The invention belongs to the technical field of food biology, and particular relates to an instant yolk oligopeptide-phosphatide type DHA double-effect dietary supplement and a preparation method thereof. The preparation method comprises the following steps of performing high-density fermentation so as to obtain microalgae powder of which the DHA content is 25-35%, adding the DHA microalgae powderto a laying hen ration to obtain strengthened eggs of which the DHA content is 200-400mg / 100g, performing pretreatment and continuous hydrolysis on DHA strengthened yolk liquid to obtain DHA strengthened yolk hydrolysate, and performing vacuum concentration refined fishy smell elimination, emulsifying, homogenizing, spray drying and boiling granulation on the yolk hydrolysate so as to obtain theinstant yolk oligopeptide-phosphatide type DHA double-effect dietary supplement. The method disclosed by the invention has the advantages of being simple in technology, free from environmental pollution, high in product yield and the like; and the total protein content of the instant yolk oligopeptide-phosphatide type DHA double-effect dietary supplement is higher than 45%, the proportion of yolkoligopeptide components in the total protein is higher than 50%, the content of DHA in the product namely the instant yolk oligopeptide-phosphatide type DHA double-effect dietary supplement is 1-3%, the maltodextrin content is 5-25%, and the instant yolk oligopeptide-phosphatide type DHA double-effect dietary supplement is particularly suitable for nutrient requirement crowds of sub-health crowds,babies at the growth and development period, women at the pregnancy period or the lactation period, postoperative patients, crowds suffering from disturbance of digestion and absorption, old people suffering from slow metabolism, and the like to eat.
