Fresh-keeping liquid for frozen food and preparation equipment thereof

Abstract

The invention provides fresh-keeping liquid for frozen food and preparation equipment thereof. The fresh-keeping liquid for frozen foods comprise the following components: ethyl alcohol, nitrate, vegetable oil, F42 high fructose corn syrup, potassium chloride and water. The contents of all components are as follows: 15%-25% of ethyl alcohol, 5%-10% of nitrate, 5%-8% of vegetable oil, 15%-25% of F42 high fructose corn syrup, 5%-12% of potassium chloride and 35%-40% of water. According to the invention, the heat of a frozen object can be treated by the partial freezing liquid in a short time; agroove type ice crystal generation area is formed at the frozen food and the internal and external pressures of food cells are relatively balanced, so that the cell tissues of frozen objects are greatly protected; and cell viability is kept, the fresh quality of frozen objects is guaranteed, and original nutritional ingredients are reserved to the greatest extent. Moreover, a quantitative feedingfunction is realized; and fresh-keeping liquid is discharged from top to bottom, so that solidified residual impurities generated after the burdening reaction of the processing tank are prevented frombeing discharged along with the fresh-keeping liquid and thus the quality of the fresh-keeping liquid is improved to a great extent.

Description

technical field [0001] The invention relates to the field of preservation of frozen foods, in particular to a freshness-preserving liquid for frozen foods and a preparation device thereof. Background technique [0002] Frozen food is divided into chilled food and frozen food. Frozen food is easy to preserve and is widely used in the production, transportation and storage of perishable foods such as meat, poultry, aquatic products, milk, eggs, vegetables and fruits; it is nutritious, convenient, hygienic and economical; The market demand is large, cooling food: no need to freeze, it is to lower the temperature of the food to close to the freezing point and store it at this temperature; frozen food: it is the food preserved at a temperature lower than the freezing point after freezing; cooling Food and frozen food are collectively referred to as frozen food, which can be divided into five categories according to raw materials and consumption forms: fruits and vegetables, aquat...
