Abstract
The invention discloses a preservative, which comprises solid organic acid and attapulgite, as well as bicarbonate adsorbed in the attapulgite, wherein a mass ratio of the solid organic acid to bicarbonate is 1: (0.2-5). Compared to an existing preservative, the preservative disclosed by the invention is longer in action time, and is capable of protecting fruits and vegetables from deteriorating in a transportation or storage process.
Description
Technical field
The present invention relates to a kind of antistaling agent for preserving fruit and vegetable utilizing.
Background technology
Rotten for preventing fruit and vegetable food from occurring in transport or storage, generally adopt low temperature storage method, or by film wrapped, or controlled atmospher is preserved, but the shelter cost of this several method is relatively high.
Newer preservation method utilizes carbon dioxide to the inhibitory action of ethene at present, react as utilized the mixture of solid acid and carbonate or bicarbonate under water what absorb that fruits and vegetables evaporate thus discharge carbon dioxide, thus realize the fresh-keeping of fruits and vegetables, but the shortcoming of this antistaling agent is, because solid acid and carbonate or bicarbonate reaction can produce water, after certain hour, obviously can accelerate reaction process, antistaling agent is consumed very soon.
Summary of the invention
The technical problem to be solved in the present invention overcomes existing defect, provides a kind of antistaling agent.
In order to solve the problems of the technologies described above, the invention provides following technical scheme:
A kind of antistaling agent, comprise solid organic acid, attapulgite, and be attracted to the bicarbonate in attapulgite, wherein, the mass ratio of solid organic acid and bicarbonate is 1:(0.2 ~ 5).
Further, described solid organic acid is fumaric acid, ethylenediamine tetra-acetic acid, citric acid, benzoic acid, salicylic acid, sorbic acid, nicotinic acid, itaconic acid, cinnamic acid, glutamic acid, vanillic acid or trichloroacetic acid.
Further, described bicarbonate is sodium acid carbonate, saleratus or calcium bicarbonate.
The present invention utilizes the porosity characteristic of attapulgite, bicarbonate is adsorbed in the duct of attapulgite, thus constraint effect is produced to bicarbonate, the water that solid organic acid is given out by fruits and vegetables and bicarbonate react, due to attapulgite duct constraint and fill by bicarbonate, make solid organic acid cannot enter duct fast, thus effectively can control the reaction process of acid and bicarbonate, and the absorption of attapulgite micropore also can slow down the release of carbon dioxide.
Detailed description of the invention
Below in conjunction with preferred embodiment, the present invention will be described, should be appreciated that preferred embodiment described herein is only for instruction and explanation of the present invention, is not intended to limit the present invention.
Embodiment 1
Mix containing the saturated aqueous solution of 20g sodium acid carbonate with the attapulgite of 180g, place after 4 hours, dry, obtain the attapulgite being adsorbed with sodium acid carbonate.
2g cinnamic acid is mixed with the above-mentioned attapulgite being adsorbed with sodium acid carbonate of 20g, then puts into the 500ml bottle of the fresh apple block that 100g is housed.Time (parallel laboratory test 3 times, averages) the 1st, 4 and 8 day, in bottle, ethylene concentration (ppm) is respectively 95,80 and 80.
Contrast: 2g cinnamic acid is mixed with 2g sodium acid carbonate, then puts into the 500ml bottle of the fresh apple block that 100g is housed.Time (parallel laboratory test 3 times, averages) the 1st, 4 and 8 day, in bottle, ethylene concentration (ppm) is respectively 95,87 and 100.
Embodiment 2
200ml is mixed with the attapulgite of 80g containing the aqueous solution of 10g saleratus, places after 2 hours, filter, dry, obtain the attapulgite being adsorbed with saleratus, detect the saleratus residual quantity of filtrate.
1g salicylic acid is mixed with the attapulgite containing 2g saleratus, then puts into the 500ml bottle of the fresh banana that 100g is housed.Time (parallel laboratory test 3 times, averages) the 1st, 4 and 8 day, in bottle, ethylene concentration (ppm) is respectively 100,90 and 85.
Contrast: 1g salicylic acid is mixed with 2g saleratus, then puts into the 500ml bottle of the fresh banana that 100g is housed.Time (parallel laboratory test 3 times, averages) the 1st, 4 and 8 day, in bottle, ethylene concentration (ppm) is respectively 100,95 and 110.
As can be seen from above experiment, compared with reference substance, saleratus, after attapulgite absorption, obviously can extend the release time of carbon dioxide, thus the ethene suppressing concentration of energy longer time.
Embodiment 3
10g fumaric acid, 5g glutamic acid, 5g vanillic acid and 0.5g trichloroacetic acid are mixed with the attapulgite (obtaining by the method for embodiment 2) containing 2g sodium acid carbonate respectively, then puts into the 500ml bottle of the fresh apple block that 100g is housed.1st day and the 8th day time bottle in ethylene concentration (ppm) be respectively 50 and 50; 45 and 46; 80 and 78; 93 and 92.
Last it is noted that the foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, although with reference to previous embodiment to invention has been detailed description, for a person skilled in the art, it still can be modified to the technical scheme described in foregoing embodiments, or carries out equivalent replacement to wherein portion of techniques feature.Within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
