Abstract
An antistaling agent for fruit, vegetable and flower is prepared from potassium permanganate and calcium silicate in weight ratio of (1-4) : (4-1). Its advantages include high safety, less consumption, quickly taking its effect and long antistaling time (3-6 months).
Description
The present invention relates to the preparation of the antistaling agent of a kind of fruit and vegetable and flowers.
The current social development pollution-free food becomes main trend, and transportation of fruit and vegetable and flowers and long preservation are problems extremely to be solved.The main cause that causes fruit and vegetable to rot is to pluck the back at its surperficial regular meeting moisture content with have many moulds, bacterium and insect pest when fresh fruit and vegetables, and fruits and vegetables will breathe in storage process simultaneously, emits ethene and CO
2Deng gas, the existence of these gases also can promote rotting of fruit and vegetable and rotten.Disclosed freshness preserving agent for fruit and vegetable CN 1068475A, CN 1133123A are coated with the surface of touching fruit and vegetable with antistaling agent at present, and secluding air prevents fungus growth, but are difficult for absorbing oxygen, ethene, CO in the storage space
2And steam, fresh-keeping effect often is restricted.Make complexity, cost height simultaneously.
The purpose of this invention is to provide a kind of new fruit and vegetable and flower antistaling agent and manufacture method thereof, its outstanding feature is the shortcoming that can overcome prior art, consumption is few, instant effect, fresh keeping time is long, safe in utilization, the present invention is applicable to the big or small fresh-keeping storage of apple, banana, grape, beans, onion, green pepper, cucumber, tomato, green vegetables or multiple flowers.
The present invention comprises that mainly potassium permanganate and calcium silicates constitute, and their weight ratio is 1～4: 4～1.
Preparation method of the present invention is as follows, and potassium permanganate solid and calcium silicates solid are crushed to 60～80 orders respectively, is mixed, and drying is removed moisture content and got final product, and perhaps the above-mentioned substance with metering fully mixes, and is crushed to 60～80, adopts the usual way drying, packing.Finished product can be in bulk, adds starch or gelatin and can be made into the tablet use.
Characteristics of the present invention are described below:
1) utilizes low tempertaure storage vegetables of the present invention, fruit and flowers etc. are earlier moisture solid to be harvested and stored in the good container of fixed ventilation as Polypropylene Bag, evenly place antistaling agent again, seal to be stored in the low temperature storehouse then and are advisable most, method is simple, is particularly useful for south vegetable north transportation.
2) antistaling agent has with thing moisture such as fruits and vegetables and keeps a certain proportion of character, thereby with its spreading on fruits and vegetables, contained humidity is just formed certain tissue by antistaling agent in the fruits and vegetables cellular tissure, is that the bacterium of medium and the procreation of microorganism are grown with water so just stoped, thus performance preservation effect.
3) the antistaling agent spreading can play a role instant effect in several minutes behind fruit and vegetable surfaces.
4) utilize equipressure or variations in temperature, the antistaling agent in the fruits and vegetables can be removed at an easy rate, and do not had any harmful effect for qualities such as fruits and vegetables.
5) antistaling agent is stable in atmosphere normal temperature, puts into air-locked plastic sack when not using and all can place at atmosphere, and active ingredient is free of losses almost.
6) nontoxic, harmless, safe in utilization, relieved reliable.
7) antistaling agent spreading amount (even spreading around the fruits and vegetables flowers product, in bulk or tablet) is by storage capacity, and about 10～20 grams of per kilogram spreading get final product, and the expense of per kilogram with medicament is at 0.03～0.60 yuan, and cost is low holds concurrently.
8) characteristics of antistaling agent maximum are to absorb ethene and oxygen, regulate temperature in the packaging bag, prevent that too much ethene from existing, and ethene exists can promote fruits and vegetables, flowers metabolism.Use the present invention can stop fruits and vegetables, flowers to breathe, can preserve 3-6 month, make the fruits and vegetables freshness constant, mouthfeel still.
Substantive distinguishing features that the present invention gives prominence to and remarkable result can be embodied from following embodiment, but they are not that the present invention is imposed any restrictions.
Embodiment 1.
Take by weighing potassium permanganate 60 grams and calcium silicates 40 grams, mixing is crushed to 70 orders, packing.Taking by weighing 1 kilogram of the kyoto grape newly plucked, to put into Air permenbility be 10000 cubic centimetres bamboo basket, place antistaling agent 20 grams of above-mentioned preparation, use the thick polythene film bag packing of 30 μ m, the packaging bag half opening, storage is 5 days under 25 ℃ of temperature, store results is: 1-10 threshing arranged in per 50, and the nondiscolouring of grape own, taste is constant.
Check experiment: do not place antistaling agent, other condition is the same, after 5 days, 10-16 threshing is arranged in per 50, and the grape variable color becomes inferior goods.
Embodiment 2
The antistaling agent raw material changes the influence of ability that ethene is removed
(1) preparation sample: different material powders and potassium permanganate are fully mixed by same proportioning, and the antistaling agent that makes is as sample.
(2) test method: get each 4 gram of antistaling agent that make, be stated from the ware, be positioned over respectively in the closed container of 10 liters of internal volumes, 5 milliliters of the ethylene gas of each implantation concentration 100% are measured ethylene concentration at regular intervals one time.After beginning to measure 24 hours, the 5 milliliters of ethylene gas that reinject are in kind measured ethylene gas concentration again.
(3) result of the test is listed in table 1
