Problems solved by technology

Passion fruit is a typical respiratory climacteric fruit with high ethylene release. If the conditions are not well grasped, it is easy to cause uneven ripening, or excessive ripening, deterioration, bad fruit, etc., and the fruit cells are destroyed. The fruit loses its original flavor and appearance, and the ripening effect is often uncontrollable; while chemical ripening methods such as ethephon solution ripening tend to cause residues on the fruit surface, affecting food safety

Abstract

The invention relates to a method for accelerating ripening of passion fruits. The method comprises the following steps: S1, performing picking; S2, spraying a ripening liquid; S3, putting the passionfruits into an illumination box, and illuminating the passion fruits for 40-60min by using a 20W red-blue chromatographic LED plant supplement lamp; S4, taking out the passion fruits, soaking the passion fruits in a sugarcane molasses solution with a concentration of 10-15%, draining and taking out the passion fruits after 2 hours; S5, putting the passion fruits into a sealed controllable ripening box for ripening; S6, spraying ripening liquid for the second time, and uniformly spraying 45-55% Hanfu solution on the surface of the passion fruits; and S7, putting the fruits into a sealed controllable ripening box for ripening again, and taking out the fruits. The method combines the safe ripening liquid with the red-blue supplement lamp designed aiming at the growth of the passion fruits toaccelerate ripening, can effectively improve the sweetness and flavor of the passion fruits, improves the content of solid substances, optimizes the color and luster of the fruits, enables the fruitsto be better sold, has uniform ripening effect, shortens ripening time, and enables the ripening process to reach a controllable range; and the fruit has no chemical residue, and the natural components of the fruits are not destroyed.

Description

technical field [0001] The invention relates to the field of increasing the yield of agricultural products, in particular to a method for accelerating the ripening of passion fruit. Background technique [0002] Xiangguo is widely distributed in tropical and subtropical regions. In my country, Guangxi has the fastest development and has become a resource advantage in Guangxi. Passion fruit has a unique flavor, high nutritional value and multiple medicinal values. The fruit can be eaten raw or used as vegetables and feed. Being used as medicine has the effect of excitement and strength. The fruit pulp is juicy, which can be made into an aromatic and delicious drink, and can also be added to other drinks to improve the quality of the drink. The seeds are pressed for oil, which can be used for food, soap making, paint making, etc., and has high-quality market potential. [0003] The current passion fruit ripening methods include ripening fruit ripening, rice ripening, temper...
