Ready-to-eat freeze-dried black wood ears and preparation method thereof

Abstract

The invention provides ready-to-eat freeze-dried black wood ears and a preparation method thereof. The preparation method comprises the following steps of (1) performing drying in sunshine and screening; (2) performing soaking and cleaning; (3) performing fixation and pre-cooking; (4) performing pre-freezing; and (5) performing freeze drying. The ready-to-eat freeze-dried black wood ears can alsobe further processed into ready-to-eat type leisure foods and brewed type beverages. According to black wood ear products, the risk of the black wood ears in the eating course can be effectively reduced; low-temperature frozen and dried black wood ears reserve color, fragrance, taste and nutrient components of fresh black wood ears, an original solid skeleton structure is not lost, and original shape of materials can be maintained. The black wood ears after processing treatment can recover to the fresh wood ear state in several minutes after being dehydrated, and the ready-to-eat black wood ears can be directly eaten and are simple and convenient to eat.

Description

technical field [0001] The invention belongs to the field of food processing, and in particular relates to an instant freeze-dried black fungus and a preparation method thereof. Background technique [0002] Black fungus contains protein, fat, polysaccharide, calcium, phosphorus, iron and other elements, as well as carotene, vitamin B1, vitamin B2, niacin, etc., and also contains nutrients such as phospholipids and sterols. Fungus is rich in nutrition and is known as "the crown of fungi". However, fresh fungus contains porphyrin, so the fungus needs to be stored after being exposed to sunlight after picking. [0003] The existing storage method of black fungus is to store after drying, and the main eating method is to cook and eat the dried black fungus after soaking. The process of eating black fungus is cumbersome, and the storage conditions and soaking time are not well grasped, which leads to damage to the nutritional content of black fungus, which is restricted by con...

AI Technical Summary

Problems solved by technology

The process of eating black fungus is cumbersome, and the storage conditions and soaking time are not well grasped, which leads to the damage of black fungus nutrients, and the eating conditions are limited

Specifically, before eating, it needs to be soaked and rinsed with water. The soaking time is long, nutrients are easily lost and there is a risk of secondary pollution.

[0004] In addition, black fungus is rich in plant collagen, which needs to be chewed and easily digested and absorbed. For the elderly and children, black fungus needs to be processed and cooked again, which is very inconvenient
