Abstract

The invention relates to the field of foods, and particularly discloses freeze-dried kumquat slices and a preparation method thereof. The freeze-dried kumquat slices are prepared by adopting a freeze-drying method. The preparation method comprises the following steps of S1, pretreating fresh kumquat fruits; S2, performing freshness locking nursing on the kumquat fruits through a nursing solution;S3, slicing and dishing up the kumquat fruits; S4, pre-freezing kumquat slices; S5, coating the kumquat slices with auxiliary materials; S6, sublimating and drying the kumquat slices; S7, analyzing and drying the kumquat slices; and S8, screening out kernels, and carrying out quality inspection and packaging to obtain the freeze-dried kumquat slices. The water content of the freeze-dried kumquat slices prepared by the preparation method is lower than 5%, so that microbial reproduction is not facilitated and product storage is facilitated; only natural auxiliary materials are added in the preparation and processing process, so that the bitter and astringent taste of kumquats can be reduced, the nutritional ingredients of the kumquat raw materials can be locked to the maximum extent, and thefreeze-dried kumquat slices are richer in nutritional value and more delicious to eat; and uniform honeycomb structures are formed among freeze-dried raw material cells or cells, so that the productis ideal in rehydration and good in brittleness and toughness.

Description

technical field [0001] The invention belongs to the field of food, and in particular relates to a kumquat freeze-dried tablet and a preparation method thereof. Background technique [0002] According to big data analysis, dried fruit is deeply loved by children and young consumers, has great potential in the food processing industry, and has a broad market prospect. However, the fruit processing industry in the domestic market is a mixed bag. Fruit processed foods are mostly made by traditional techniques such as sulfur fumigation, alkali staining, and heat drying, and most of them add preservatives and antioxidants that do not meet food safety regulations in the production process. Additives that are harmful to human health, which to a certain extent lose the original flavor and nutritional content of the fruit, and run counter to the current trend of green and healthy consumption. For this reason, the industry has been continuously improving the production process of drie...
