Problems solved by technology

[0009] The method of adopting cold storage and preservation will not affect the taste and quality of strawberries, but the storage period is shorter; although the method of quick freezing and preservation can ensure long-term storage of strawberries at low temperatures, the taste and quality of strawberries are greatly reduced; Seasoned storage has strict requirements on storage conditions and equipment, which increases the cost of strawberry fresh-keeping storage

Abstract

The invention provides a method for preserving and storing strawberries. The technical scheme of the method is to preserve strawberries by immersing the strawberries in a fruit antistaling agent which is prepared by 2 to 3 parts by weight of citric acid, 5 to 7 parts by weight of sodium pyrosulfite, 35 to 45 parts by weight of calcium chloride and 900 to 1100 parts by weight of water. In the invention, addition of calcium chloride into the antistaling agent enables hardness of strawberries to be increased, which is beneficial for preservation and storage of strawberries; addition of citric acid in the process of cleaning and storing of strawberries enables a fresh-keeping effect and reduction of decay proportion of strawberries; citric acid and calcium chloride in the fruit antistaling agent provide an acidic environment, sodium pyrosulfite reacts to generate sulfur dioxide under the condition of acid, and the acidic solution of sulfur dioxide discolors strawberries, which is beneficial for preservation and storage of strawberries. According to the method provided in the invention, strawberries are stored in liquid, which is favorable for transportation and avoids mechanical damage resulting from collision; utilization of the method ensures a long preservation period for strawberries without decay and deterioration.

Description

technical field [0001] The invention relates to the field of fruit preservation, in particular to a fresh-keeping and storage method for strawberries. Background technique [0002] Strawberry is a low-sugar and low-calorie berry with high nutritional value and is loved by people. Its main nutrients include sugar, vitamins, minerals, organic acids and pectin. At the same time, strawberry is a non-climtic respiration fruit with high water content and thin skin, which is easily damaged and rotted. Therefore, it is not resistant to storage and transportation. Usually, the storage period is 1 to 2 days, which severely limits sales and processing. [0003] The hardness of strawberries after harvest determines the length of fruit storage time. Generally, the hardness of strawberries decreases rapidly after harvesting, and high carbon dioxide, low oxygen and controlled atmosphere can maintain the hardness to varying degrees. Existing strawberry preservation methods include the fol...
