Simulated cave natural orange freshness keeping method and simulated cave natural orange freshness keeping system

Abstract

The invention discloses a simulated cave natural orange freshness keeping method and a simulated cave natural orange freshness keeping system and belongs to the field of orange storage and freshness keeping methods and facilities. The natural orange freshness keeping method comprises the following steps: A. storage space sterilization: dosing ozone to a storage space of an underground store for sterilization; B. picking: picking oranges with the maturity degree of 8.5 to 9 (E / A); picking all fruits to be kept fresh and stored before First Frost at the local place, and performing preservative treatment after the picking; C. precooling: boxing, placing in a cold room with 10 DEG C, filling carbon dioxide and precooling for 24h, wherein no precooling is needed when temperature of the fruits is lower than 10 DEG C; D. simulating cave freshness keeping and storage, wherein a simulated cave is the underground store isolated from a -18 DEG C low-temperature cold store by division plates, and the underground store is located underground on the whole and is controlled at constant temperature. The simulated cave natural orange freshness keeping method and the simulated cave natural orange freshness keeping system have the advantages of simplicity in operation, long freshness lifetime, good freshness keeping effect, energy saving and no environmental pollution, and are suitable for large-scale orange treatment.

Description

technical field [0001] The invention relates to an orange storage and fresh-keeping method and facilities, in particular to a natural fresh-keeping method and a simulated cave-dwell orange fresh-keeping system. Background technique [0002] Fruits are still living organisms in the post-harvest storage, transportation, and sales systems, and they still carry out metabolic activities as before harvest. Physiological and biochemical changes in their cells are largely a continuation of metabolic processes during the reproductive years of these organisms. However, the postharvest fruits no longer absorb water and nutrients from the soil, and basically no longer carry out photosynthesis. Qualitative and quantitative changes. As fresh fruits are food and commodities, consumers naturally pay attention to their nutritional value, edible quality and commodity value. Generally, they hope to maintain the quality and quality of fruits when they are harvested to the maximum extent. Kee...

Problems solved by technology

Although the mechanical atmosphere controlled low temperature storage method can adjust the gas composition in the cold storage, it does not affect the CO 2 There is not enough regulation

In the area of ​​Jiangxi, cold storage and controlled atmosphere storage generally have short storage and fresh-keeping periods, poor yields, and poor fresh-keeping quality, which is difficult to meet the growing consumer market demand.
