Embodiment 1

[0020] A coating agent for delaying dehydration and shrinkage of passion fruit peel, the coating agent comprises the following components in mass percent: 4% chitosan, 3% oleic acid, 3% myristic acid, 2% glycerin, 6% green Original acid and the balance distilled water.

[0021] A method for delaying dehydration and shrinkage of passion fruit peel, the method comprising:

[0022] After the healthy and mature passion fruit is picked, the above-mentioned coating agent is evenly coated on the surface of the fruit, and the wax liquid on the surface is dried by the coating film, and stored indoors.

Embodiment 2

[0024] A kind of film coating agent that delays passion fruit pericarp dehydration shrinkage, and embodiment 1 is basically the same, difference is: film coating agent comprises the component of following mass percent: 3% chitosan, 4% oleic acid, 5% Myristic acid, 3% glycerin, 7% chlorogenic acid and the balance distilled water.

Embodiment 3

[0026] A kind of coating agent that delays passion fruit pericarp dehydration shrinkage, is basically the same as embodiment 1, difference is: coating agent comprises the component of following mass percent: 6% chitosan, 3% oleic acid, 5% Myristic acid, 4% glycerin, 6% chlorogenic acid and the balance distilled water.

Abstract

The invention discloses a film coating agent for delaying water loss and shrinkage of passion fruit peel and application thereof. The film coating agent comprises the following components in percentage by mass: 3-6% of chitosan, 3-4% of oleic acid, 3-5% of myristic acid, 2-4% of glycerol, 6-7% of chlorogenic acid and the balance of distilled water. The film coating agent for delaying water loss and shrinkage of the passion fruit peel is good in preservation effect, water loss of the passion fruit peel is effectively reduced, and the color turning time of the peel is delayed so that the integrity of the passion fruit peel and the internal quality of the passion fruit are effectively kept, and the shelf life of the passion fruit is prolonged.

Description

technical field [0001] The invention relates to a method for delaying dehydration and shrinkage of pericarp, in particular to a coating agent for delaying dehydration and shrinkage of passion fruit pericarp and application thereof. Background technique [0002] Passion fruit is a herbaceous vine of the Passiflora family Passiflora, mainly including purple fruit and yellow fruit. The fruit is a berry, ovoid, with a longitudinal diameter of 5-7cm and a transverse diameter of 4-6cm. The young fruit is green, the mature fruit is purple or yellow, the leather is tough and smooth, the pulp is yellow, and the pulp is filled with yellow juice, like raw egg yolk , juice content 30% to 40%. [0003] Passion fruit is very sensitive to the storage environment. Within 2 to 3 days after harvesting at room temperature, the passion fruit skin will lose a lot of water, and the pulp will ferment and liquefy. Moreover, passion fruit will release a large amount of ethylene after harvesting, w...
