Abstract

The invention provides a fresh-preserving method of fresh dried bean milk cream in tight rolls. The fresh-preserving method comprises the following steps of a, half-drying treatment; b, sterilization; c, vacuum packaging; d, quick-freezing treatment; and e, storage. The method has the advantages that: 1, the soft taste of the fresh dried bean milk cream in tight rolls can be preserved, the beany flavor and nutrition in the fresh dried bean milk cream in tight rolls can be preserved as well; 2, the fresh preservation period is prolonged to 3-4 months in the case that no additive is added; 3, the aim of instant taking can be achieved since the fresh dried bean milk cream in tight rolls can be taken without cleaning or soaking; and 4, the fresh dried bean milk cream in tight rolls are a purely natural food, and do not contain additive harmful to the human bodies.

Description

technical field [0001] The invention belongs to a fresh-keeping method, in particular to a fresh-keeping method for fresh soybean oil. Background technique [0002] Yuba, also known as yuba or bean curd skin, is a solidified film on the surface of boiled soybean milk, which can be eaten fresh or dried. [0003] The bean curd sticks in Hubei Province, especially Fangxian County, Hubei Province, are also known as soybean oil essence. Soybean oil is a kind of high nutritional value (about 50% protein, 25% fat), easy to store, convenient to eat, and can be made into a variety of delicious vegetarian products. [0004] At present, there is a problem of deterioration of fresh soybean oil if it is not eaten in time after it is processed, resulting in a very short shelf life of fresh soybean oil. The traditional method of preservation is to adopt the method of drying or drying naturally, but there are the following problems: 1. The traditional method needs to completely lose moist...
