Embodiment 1

[0019] 10 parts of acrylic acid are placed in a flask, neutralized with a 40% sodium hydroxide solution with a mass concentration, acrylphenolamine with acrylic acid molar ratio of 2, and azobisisobutyronitrile (1) with acrylic acid molar ratio AIBN), and the molar ratio of acrylic acid to 2 methylenebisacrylamide, and fully dissolved with the mixture, after mixing evenly, the solution was transferred to the polymerization reaction tube, replaced by nitrogen for 5 min and then sealed. Place the reaction tube in a constant temperature shaking water bath at 60°C for 24 h to obtain a cross-linked polymer dispersion, wash with acetone solution, remove unreacted monomers through several centrifuges, and then filter and dry to obtain acrylphenolamine / acrylic copolymer.

Embodiment 2

[0021] First add 12 parts of sodium chloride into a clean empty beaker, then add 40 parts of water and stir to form a sodium chloride solution, then add 14 parts of mannitol, 10 parts of malic acid, 22 parts of xylitol, 9 parts of sodium diacetate, 10 parts of butanediol and 13 parts of calcium lactate were added to the sodium chloride solution respectively, and the pH value was adjusted to 8~10 with sodium hydroxide, then 9 parts of acrylphenolamine / acrylic acid copolymer were added, and mechanically stirred at room temperature 30 min, then ultrasonic vibration for 20 min, after the vibration, the prepared cool storage agent was left to stand for 7 days in a constant temperature environment without vibration.

Embodiment 3

[0023] First add 10 parts of sodium chloride into a clean empty beaker, then add 40 parts of water and stir to form a sodium chloride solution, then add 16 parts of mannitol, 8 parts of malic acid, 24 parts of xylitol, 7 parts of sodium diacetate, Add 12 parts of butanediol and 11 parts of calcium lactate to the sodium chloride solution respectively, adjust the pH value to 8~10 with sodium hydroxide, then add 6 parts of acrylphenolamine / acrylic acid copolymer, and stir mechanically at room temperature 30 min, then ultrasonic vibration for 20 min, after the vibration, the prepared cool storage agent was left to stand for 7 days in a constant temperature environment without vibration.

Abstract

The invention discloses a cold storage agent for kiwi fruit storage. The cold storage agent comprises: a copolymer, mannitol, malic acid, xylitol, sodium diacetate, butanediol, calcium lactate, and aphase change temperature regulator.

Description

technical field [0001] The invention relates to the field of cold storage, in particular to a cold storage agent for kiwi fruit storage. Background technique [0002] Kiwifruit is a deciduous perennial vine fruit tree belonging to Actinidiaceae Actinidia genus. It is a semi-shady plant with strong adaptability and avoids strong sunlight. It is native to the Yangtze River Basin in my country and mostly grows below 2000m above sea level. Kiwifruit is also called carambola, Rattan pear, Maoli peach. At present, 66 species of kiwifruit trees have been found all over the world, among which 62 species of kiwifruit trees exist in our country. It can be seen that our country has very rich kiwifruit germplasm resources. The history of kiwi cultivation originated in Shaanxi 1200 years ago. According to relevant information, there are already records about kiwifruit in Erya and The Book of Songs two or three thousand years ago; there are also verses describing kiwifruit in the poems o...
