Preparation method of ganoderma lucidum and red jujube yoghourt

Abstract

The invention discloses a preparation method of ganoderma lucidum and red jujube yoghourt. The preparation method comprises the following steps of (1) preparing ingredients in a weight ratio of 10-15%of nonfat dry milk, 6-8% of cane sugar, 5-20% of ganoderma lucidum and red jujube fermentation liquor, 0-5% of red jujube granules and the balance water; (2) performing uniform mixing and sterilization: performing uniform mixing through mechanical stirring, and performing sterilization at 80-90 DEG C for 18-22 minutes; (3) performing inoculation and subpackaging: performing cooling to 42-46 DEG C, adding yoghourt fermentation bacterium liquor, performing uniform mixing, performing subpackaging into yoghourt bottles, and performing sealing well; and (4) performing fermentation and performing cooling. Through the steps of preparing yoghourt ingredients, fermenting the yoghourt and the like, the ganoderma lucidum and red jujube yoghourt is obtained, nutrition, mouth feel of red jujubes, oxidation resisting efficacy and the like are given to the ganoderma lucidum and red jujube yoghourt, besides, the use of thickening agents and preservatives is reduced, and the ganoderma lucidum and redjujube yoghourt facilitates the health of human bodies.

Description

technical field

[0001] The invention relates to the fields of fermentation engineering, deep processing of agricultural products and the like, and in particular relates to a preparation method of ganoderma lucidum jujube yoghurt. Background technique

[0002] Yogurt is a kind of milk product that uses milk as raw material, after pasteurization and then adding starter, after fermentation, and then cooling and filling. During the fermentation process of fermented bacteria, lactose is converted into lactic acid, and calcium element is converted into calcium lactate, which can promote human digestion and improve immunity. Long-term drinking can not only ensure the calcium demand, but also strengthen the stomach and regulate the human body Metabolism, improve people's disease resistance, so more and more people are favored.

[0024] Step 1: After peeling and cutting the potatoes, add 4 times the mass of deionized water, boil for 30 minutes, filter to get the filtrate, add 2% sucrose in total mass, dissolve, adjust to the volume before boiling with deionized water, and the obtained solution is liquid medium for potatoes. Two pieces (1cm×1cm) of ganoderma lucidum slant strains were aseptically inserted into 100mL potato liquid medium, cultured on a shaker at 28°C and 150r / min for 5 days, and the same method was continuously transferred for 2 generations, and then the obtained The seed liquid is aseptically inserted into a certain volume of potato liquid medium at a volume ratio of 10% for expanded cultivation. The expanded cultivation conditions are 28°C, 150r / min, ventilation volume VVM=1:1, and cultivated for 3 days to obtain The seed liquid can meet the needs of fermentation;
