Abstract

The present invention discloses a preparation method of freeze-dried instant edible bird's nest products. The preparation method comprises the following steps: impurities of fresh edible bird's nest or dry edible bird's nest are removed, and the impurity removed edible bird's nest is soaked in pure water at a temperature of 10-40 DEG C for 1-8 h to obtain soaked edible bird's nest; edible saccharides are added into the soaked edible bird's nest and heating is conducted at a temperature of 90-120 DEG C for 20 min-4 h to obtain liquid edible bird's nest; the liquid edible bird's nest is poured into a mold and quick-frozen at a temperature of -40 DEG C to -15 DEG C for 4-8 h to obtain solid-state edible bird's nest; and the obtained solid edible bird's nest is placed into a vacuum freeze-drying furnace to be freeze-dried for 15-24 h to obtain the freeze-dried edible bird's nest products. Without changing the original form of the freshly stewed edible bird's nest, the preparation method retains the nutritional value of the edible bird's nest. The edible bird's nest has the characteristics of being long in storage time without adding any additives and preservatives, is beneficial to the industrial production, safe and convenient in consumption, and can be brewed with water at any temperature for consumption. After the brewing, the taste and the original shapes of the freshly stewed edible bird's nest are maximally restored and the edible bird's nest products are in line with people's eating habits.

Description

technical field [0001] The invention belongs to the field of food, in particular to a freeze-dried instant bird's nest food and a preparation method thereof Background technique [0002] Bird's nest, as a traditional nourishing food, is becoming more and more popular among domestic people. However, because the traditional stewing process of bird's nest is too complicated, bird's nest has not really become popular; The cooking time and temperature requirements are relatively high, so it is difficult to artificially standardize. [0003] In recent years, although there are various instant bird's nest products that are convenient for consumers, in order to maintain the taste of bird's nest and prolong the shelf life of products, these products often add some additives or preservatives, or change the original form of bird's nest for processing, thus Losing the meaning of food bird's nest, it is necessary to develop a standardized ready-to-eat bird's nest product with zero addit...
