Citrus fruit post-harvest treatment method

Abstract

The invention discloses a citrus fruit post-harvest treatment method which comprises the steps of: 1) selecting raw materials, wherein fruits entering post-harvest commercial treatment are edible and mature, have flush pedicels and are low in minimal damage rate; 2) performing broad-spectrum sterilization, cleaning and pre-screening on the fruits, namely soaking the fruits which delivered to a post-harvest treatment factory and are checked to be qualified by using a broad-spectrum sterilization agent and a surfactant, cleaning the fruits by using clean water, pre-screening the fruits until out-level fruits are screened out of a production line, and performing preservation and freshness retaining on the fruits sold as high-quality commercial fruits; 3) removing green from the fruits, namely treating the pre-screened fruits which are treated by preservatives and are required to be subjected to green removal by using ethylene; and 4) supplying an environment condition requirement, namely constructing a cold chain system for post-harvest early mature and late mature citruses in high temperature seasons. By adopting the citrus fruit post-harvest treatment method, the problem of pollution caused by pesticide residue for deep processing is solved; the using amount of preservative freshness retaining agents can be effectively controlled, and the emission of production waste water is reduced; the cost is saved; and the citrus fruit post-harvest treatment method has the characteristics of practicability, economical property and environment friendliness.

Description

technical field [0001] The invention belongs to the technical field of storage and preservation of fresh and live agricultural products, and in particular relates to a postharvest treatment method for citrus fruits. This method is suitable for the post-harvest production of citrus and other fruits and the process improvement of equipment manufacturing enterprises. Background technique [0002] 1. Industrial demand for postharvest treatment of citrus fruits [0003] In 2010, the global citrus cultivation area was 8.64 million hectares, distributed in 135 countries and regions, with an annual output of 124 million tons, accounting for 20.3% of the world's total fruit production; ranking first among all fruit trees. In 2010, the global citrus export volume reached 10.594 billion US dollars. In 2010, the total output of citrus in my country was 26.45 million tons, and the planting area was 2.21 million hectares. It is the most important fruit tree crop in the Yangtze River Basi...

Problems solved by technology

Due to the pre-sorting of the super-grade fruits and surface-defective fruits accounting for more than 20% of the total output before the antiseptic and fresh-keeping treatment, all of them were treated with chemicals, resulting in the pesticide residues of these freshly treated fruits exceeding the standard and it is difficult or difficult to carry out further processing and comprehensive utilization. , but also consumed a large amount of preservatives, making the overall utilization rate of preservatives low, and the effect of antiseptic preservation is not good

On the other hand, most post-harvest treatment plants fail to treat production wastewater and discharge it directly. The environmental pollution problems around the post-harvest treatment plants cannot be ignored for a long time.
