Abstract

The invention relates to auricularia nigricans yoghourt and a preparation method thereof, and belongs to the field of food processing. The auricularia nigricans yoghourt is mainly prepared from the following raw materials in parts by weight: 2-8 parts of fresh milk, 1-2 parts of auricularia nigricans, 1-6 parts of water, 0.2-1.0 part of a sweetness adjusting agent, and 0.04-0.5 part of a compositefermenting agent. The preparation method of the auricularia nigricans yoghourt comprises the following steps of freezing the auricularia nigricans, performing microwave unfreezing, performing superfine crushing treatment, adding water to obtained powder, and performing superhigh pressure treatment so as to obtain auricularia nigricans slurry; and adding fresh milk according to the formula, performing preheating, adding the sweetness adjusting agent, performing homogenizing treatment, performing ultrasonic treatment, performing sterilization, adding the composite fermenting agent for fermentation, and performing refrigeration so as to obtain the auricularia nigricans yoghourt. The method solves the problems that a conventional eating method for the auricularia nigricans is single and the added value is low, the prepared auricularia nigricans yoghourt has the health-care efficacy of improving yoghourt, and the preparation method achieves the purpose of shorting the fermentation time.

Description

technical field [0001] The invention belongs to the field of food processing, and mainly relates to yoghurt with jade fungus and a preparation method thereof. Background technique [0002] Yogurt is rich in nutrients and contains a large number of vigorous lactic acid bacteria. The lactic acid produced in the intestine can adjust the balance of the intestinal flora in the human body, inhibit the reproduction of harmful bacteria, and promote intestinal peristalsis and metabolism of body substances. However, the current market yogurt has problems such as long fermentation time and acidic taste. Jade fungus belongs to the genus Auricularia genus of the fungus kingdom Fungus. Jade fungus is a white fine variety cultivated by gene improvement and cross-domestication of Auricularia auricula. It has the characteristics of stable genetics and large yield. Jade fungus has a delicate taste, firmness, white color, and a delicate fragrance. It is called "Bai Fumei" in the fungus world....
