Embodiment 1

[0013] 1. Harvest at the right time: Choose 7-8 mature red crispy pear fruits without pests, bruises, and rot for harvesting. At this time, the fruit growth and development period is about 150 days, 1 / 2 to 2 / 3 of the seed color area turns brown, and the fruit hardness is greater than 6.35kg / cm 2 , the soluble solid content is 11.0%-12.0%. The harvested fruit is packed into a plastic turnover box, and transported to the storage warehouse or the fruit post-harvest commercialization processing center within 12 hours for subsequent processing.

[0014] 2. Antiseptic treatment: soak the harvested red crispy pear fruit in 30mg / L chlorine dioxide for 3 minutes, and use clean water below 20°C when dispensing to achieve the effect of disinfection and cooling.

Abstract

The invention relates to a fruit preservation method, and concretely provides a red fragrant pear storage fresh-keeping method. Harvested red fragrant pear fruits are immersed in a chlorine dioxide solution and then are subjected to ventilation, air drying, packaging and precooling; the 1-MCP sustained release agent and a potassium permanganate ethene remover are added, mixed gases of oxygen, carbon dioxide and nitrogen are inputted into an air regulating box, and air regulating storage is carried out. The red fragrant pear storage fresh-keeping method combines physical and chemical methods, air regulating fresh-keeping storage of red fragrant pear fruits is carried out, fresh-keeping red fragrant pear fruits are stored for 8-10 months, color and fragrance of fruits at harvest are kept basically within 10 shelf days after warehouse-out, yellowing of pericarp is delayed obviously, the fruit rotting rate is lowered, and quality and flavor of fruits are kept.

Description

technical field [0001] The invention relates to a method for preserving fruit, in particular to a method for storing and preserving red crispy pears.
