Technical Field
The invention relates to the technical field of fruit and vegetable preservation, in particular to a high-efficiency ethylene absorbent for fruit and vegetable preservation and a preparation method thereof.
Background
The fruits and vegetables are gradually softened after being harvested, because the fruits and vegetables generate a natural ripener-ethylene through self metabolism, the ethylene is a plant hormone which can promote the respiration of the fruits and vegetables and accelerate the ripening and aging, and particularly in a closed fruit and vegetable storage space, ethylene gas is gradually accumulated along with the extension of the storage period, so that the self ripening effect is generated on the fruits and vegetables, the continuous circulation is realized, the normal metabolism of the fruits and vegetables is influenced, the aging process and the decay of the fruits and vegetables are promoted to increase, and the storage period of the fruits and vegetables is shortened. Therefore, the ethylene concentration in the storage and transportation environment of the fruits and vegetables is reduced by adopting the related technology, the preservation period of the fruits and vegetables can be prolonged, and the quality of the fruits and vegetables is improved. In order to better maintain the quality of picked fruits and vegetables and prolong the storage period of the fruits and vegetables, people are constantly researching and developing ethylene removal technology suitable for the preservation of fruits and vegetables, and research on ethylene absorbents becomes a hotspot.
The existing ethylene absorbent is usually a carrier material loaded with potassium permanganate, the carrier material is usually composed of zeolite, activated carbon and the like, the cost of the zeolite, the activated carbon and the like is high, the zeolite, the activated carbon and the like are not easy to obtain, the ethylene absorbent is not suitable for most of fruit growers and the like, and the popularization and the use of the ethylene absorbent are not facilitated; on the other hand, although the existing ethylene absorbent has a certain antiseptic and fresh-keeping effect, the inherent nutrient substances of the preserved fruits and vegetables are lost to a certain extent.
Disclosure of Invention
Aiming at the defects of the prior art, the invention provides a high-efficiency ethylene absorbent for fruit and vegetable preservation and a preparation method thereof, which can efficiently absorb ethylene in the storage and transportation environment of fruits and vegetables and can simultaneously preserve and preserve the fruits and vegetables.
The invention is realized by the following technical scheme:
the invention provides a high-efficiency ethylene absorbent for fruit and vegetable preservation, which comprises a high-efficiency adsorption carrier loaded with saturated potassium permanganate and active calcium oxide, wherein the raw material of the high-efficiency adsorption carrier loaded with the saturated potassium permanganate comprises shell powder.
The potassium permanganate has strong oxidizing property, and can oxidize ethylene in the storage and transportation environment of the fruits and the vegetables, so that the content of the ethylene is reduced, and the aim of keeping the fruits and the vegetables fresh is fulfilled. In order to fully exert the ethylene absorption capacity of potassium permanganate, proper carriers need to be selected to absorb potassium permanganate. The shell resource is rich in China, the price is low, the shell has a sheet or strip-shaped microstructure, the porosity and the specific surface area are large, the adsorption is excellent, the ethylene absorption effect is realized, and the shell can be used as an excellent carrier of potassium permanganate. The shell has high porosity, and the superior pore structure is favorable for gas to diffuse into the pores to contact with potassium permanganate, so that the shell is an environment-friendly absorbent. The small amount of chitin contained in the shell and the product of the shell after being sufficiently calcined at high temperature have good sterilizing capability and can be used for preserving and refreshing fruits and vegetables.
Preferably, the shell powder comprises fanshell powder and/or conch shell powder and/or clam shell powder and/or pearl shell powder.
The shells of the conch, the scallop, the clam and the pearl shell in China are rich in resources, and the chemical compositions and microstructures of the shells are not only common but also different, but can be used as an adsorption carrier of saturated potassium permanganate. Compared with the ethylene absorbent prepared by taking the shell powder of the conch, the scallop, the clam and the pearl shell as the main potassium permanganate carrier without adding the shell, the ethylene absorbent has very obvious fresh-keeping effect, but has better effect on improving single indexes such as fruit hardness, soluble solid content, titratable acid content, rotting rate and the like than the effect of adding the mixed powder of the conch, the scallop, the clam and the pearl shell.
Preferably, the shell powder comprises fanshell powder, conch shell powder, clam shell powder and pearl shell powder.
Based on the effect of the ethylene absorbent prepared by respectively taking the shell powder of the conch, the scallop, the clam and the pearl shell as the main carrier of the potassium permanganate, the fresh-keeping effect of the four shell powders is adopted, and the fresh-keeping effect has good synergistic effect after the four shell powders are matched, so that the comprehensive fresh-keeping effect on fruits is better than that of the single use.
Preferably, the raw material of the high-efficiency adsorption carrier loaded with saturated potassium permanganate also comprises sepiolite powder. The sepiolite has natural adsorbability to potassium permanganate and can be used as a good adsorption carrier of potassium permanganate.
Preferably, the raw material of the high-efficiency adsorption carrier loaded with saturated potassium permanganate comprises the following components in parts by weight:
3-6 parts of scallop shell powder, 1-3 parts of conch shell powder, 1-3 parts of clam shell powder, 1-3 parts of pearl shell powder and 1-3 parts of sepiolite powder.
Based on the synergistic effect of the conch, the scallop, the clam and the pearl shell powder, the research finds that the weight proportion has the best fresh-keeping effect on fruits and vegetables.
Preferably, the active calcium oxide is obtained by fully calcining shell powder at high temperature.
Preferably, the active calcium oxide is prepared by mixing scallop shell powder, conch shell powder, clam shell powder and pearl shell powder in equal proportion and then fully calcining at high temperature. The active calcium oxide can also be obtained by mixing one or more of scallop shell powder, conch shell powder, clam shell powder and pearl shell powder in equal proportion and then calcining at high temperature, but the active calcium oxide prepared by mixing the four shell powders in equal proportion has the best effect.
Preferably, the shell powder and the sepiolite powder are ball milled powders.
Preferably, the high-efficiency adsorption carrier loaded with saturated potassium permanganate and the active calcium oxide are packaged respectively.
The invention also provides a preparation method of the high-efficiency ethylene absorbent for fruit and vegetable fresh-keeping, which is used for preparing the high-efficiency ethylene absorbent, and the method comprises the following steps:
s01: fully mixing the raw materials of the efficient adsorption carrier of saturated potassium permanganate according to the proportion, soaking the mixture in a saturated potassium permanganate solution at the temperature of 30-60 ℃ for 15-30 minutes, filtering, and drying at the temperature of 60-100 ℃ to prepare the adsorption carrier loaded with saturated potassium permanganate;
s02: fully calcining shell powder at high temperature to prepare active calcium oxide;
s03: and (4) respectively filling the adsorption carrier loaded with the saturated potassium permanganate prepared in the step (S01) and the activated calcium oxide prepared in the step (S02) into non-woven fabric bags to obtain the high-efficiency ethylene absorbent for keeping fruits and vegetables fresh.
