Fruit preservation method and product of fruit

Abstract

The invention discloses a fruit preservation method and a product of fruit. The method includes the steps of inactivation, namely breaking pulp cells of the fruit to release contents of the cells andstopping metabolism of the cells; ripening, namely placing the broken product to be mature; preservation, namely freezing the ripened product. With the method that the fruit cells are subjected to wall breaking through inactivation, cell contents with high quality fruit flavor and taste are obtained; cell biological metabolism is stopped to avoid cryogenic frostbite; sugar is converted into fruitacid through ripening, digestion and absorption is facilitated, and health is benefited; better taste and flavor can be obtained by ripening, so that the fruit with different maturity can reach the same maturity, which is convenient for industrial production and management; freezing slows down or even chemical reactions stop in the fruit can keep fresh for a long time without adding any preservatives; the product is convenient to eat, elegant, convenient to transport and efficient, and the worldwide problem of fruit transportation and preservation is solved.

Description

technical field [0001] The present application relates to the field of fruit preservation, in particular to a method for fruit preservation and products thereof. Background technique [0002] With the improvement of people's living standards, fruit is an indispensable food for daily healthy diet. However, on the one hand, fruits (such as peaches, mangoes, mulberries, lychees, etc.) have strong seasonality, and it is difficult for consumers to eat these fruits outside the picking season. On the other hand, picking, preserving and transporting fruits is an extremely difficult problem. The traditional method of fruit transportation is to pick the fruits when they are seven or eight mature or less mature, carry out long-distance transportation at a low temperature of 4-10°C, and then use natural conditions or chemical ripening to make the fruits mature during transportation or storage. , Mature in the sales process. The traditional methods of fruit picking, storage and transp...

AI Technical Summary

Problems solved by technology

The traditional methods of fruit picking, storage and transportation have the following problems: (1) For transportation in different places, only immature fruits can be picked, and consumers in different places will never be able to eat fruits that are naturally ripe on the plant, and cannot satisfy high-quality fruits. Consumer demand; (2) It is extremely difficult to control the ripeness of fruits during transportation, storage, and sales; (3) Low-temperature transportation or storage is likely to cause frostbite of fruits and affect fruit quality; (4) Some fruits are afraid of pressure and touch, and transportation It is easy to cause bruises during the process

However, in order to preserve the quality, non-fruit ingredients such as preservatives are usually added in fruit products, which lack the fragrance and mouthfeel of fresh fruits
