Embodiment Construction

[0019] The preferred embodiments of the present invention are described in detail below, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, so as to define the protection scope of the present invention more clearly.

[0020] A processing technology for ozone-treated fresh-cut apples: pick fresh apples after harvest, remove pests, moldy and rotten fruits, and then pack them into boxes. Take one slow-release tablet, seal the apple box, and store it in a cold storage with a temperature of -1.0-1.0 ℃ and a humidity of 80%-90%. When necessary, the apples can be taken out at any time, cleaned, and then the core pulp of the apples is removed by the corer, and the apples are cut according to the product requirements. Generally, the apples are cut into 6 to 10 pieces on average. Put the fresh-cut apples in a closed room or in a container and pass the ozone gas generated by the ozone generator, the ozone concentration ...

Abstract

The invention discloses a processing process for freshly-cut apples by ozone treatment. The processing process comprises the following steps: (1) treating collected apples by 1-methylcyclopropene (1-MCP) and refrigerating at a refrigeration temperature from -1.0 DEG C to 1.0 DEG C and at the humidity of 80%-90%; (2) washing the apples for freshly cutting and instruments and equipment and the like in a processing process; (3) cutting and removing the core, namely cutting the apples into fresh slices with certain thickness and shape according to product requirements; (4) carrying out the ozone treatment, namely carrying out ozone gas suffocating treatment on the freshly-cut apples in a closed space; (5) packaging by a thin film bag, namely packaging the freshly-cut apples by the selected food-grade preservation thin film bag according to a certain volume or weight and sticking a label; and (6) refrigerating, namely preserving the food-grade preservation thin film bag in a cold storage with the environmental temperature from -1.0 DEG C to 1.0 DEG C. With the adoption of the freshly-cut apples processed by the invention, the preservation period is long, the loss of nutrient substances is less, the flavor is pure and no residual toxins exist; the rapid and large-scale production can be realized and the requirements of the freshly-cut apples by a market are met.

Description

1. Technical field [0001] This product relates to the field of agricultural product processing, in particular to a processing technology for ozone-treated fresh-cut apples. 2. Background technology [0002] Fresh-cut apples refer to a new type of processed apple products that are processed by grading, cleaning, trimming, peeling, cutting, fresh-keeping, packaging, etc., for consumers to eat immediately or for the catering industry. Processed apples, lightly processed apples. Fresh-cut apples are different from other traditional processed apples such as apple juice and preserved apples. After a series of treatments, fresh-cut apples can still maintain their freshness. They have the nutrition and flavor of fresh apples, and are easy to eat. They are favored by consumers. . my country is rich in apple resources, which provide sufficient raw materials for the production of fresh-cut apples. [0003] During the processing of fresh-cut apples, cell juice exudates due to cutting...
