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

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
