Abstract

The present invention provides a near-freezing point spontaneous modified atmosphere preservation method for Zaojin crisp pears and belongs to the technical field of fruit preservation and storage. The method comprises Zaojin crisp pear fruit harvesting, MAP packaging, pre-cooling, preservative treating, boxing and stacking, near-freezing point storing, etc. and is a complete set of a near-freezing point spontaneous modified atmosphere packaging method for the Zaojin crisp pears. Compared with a conventional cold storage method, the Zaojin crisp pear fruits meet technical requirements in storage and preservation temperature control indexes and at the same time, an O<2> and CO<2> ratio in packaging bags is kept within a suitable range, thereby maximizing inhibition of growth of microorganisms causing spoilage of the Zaojin crisp pears and reducing rot and browning. The method is used to store the Zaojin crisp pear fruits, storage time can be as long as 10 months, a fruit loss rate is less than 5%, and a good fruit rate is higher than 95%.

Description

technical field

[0001] The invention relates to the technical field of fruit freshness preservation, in particular to a method for spontaneous modified atmosphere preservation of Zaojinsu pears near freezing point. Background technique

[0002] "Zaojinsuli" is an excellent variety independently selected and bred by the Liaoning Provincial Institute of Pomology Science. The parents are "Zaosuli" × "Jinshuisu". Zaojinsu pear is a respiratory climacteric fruit, and it matures in the hot early August, which leads to vigorous physiological metabolism after harvesting, and the peel is very easy to yellow, and the supply time of fresh fruit is short. Generally, browning, loss of Water, or even rot and deterioration, the flavor is obviously deteriorated, seriously affecting the commodity quality and sales price of Zaojinsu pear. Contents of the invention

[0003] The purpose of the present invention is to provide a method for spontaneously controlling the freshness of Zaojinsu pe...
