Abstract
The invention belongs to the technical field of household chemicals, and particularly relates to a fruit and vegetable fresh-keeping agent. The fruit and vegetable fresh-keeping agent comprises the following ingredients in percentage by mass: 1-3 percent of garlic essential oil, 0.5-3 percent of chitosan, 2-20 percent of an organic solvent, 1-10 percent of a globe artichoke extract and the balance of sterile water. Compared with the prior art, the fruit and vegetable fresh-keeping agent disclosed by the invention can form a protective membrane layer with permeability and watertightness on the surfaces of fruits and vegetables by a synergistic interaction effect of the garlic essential oil, the chitosan and the globe artichoke extract, and also has a quite good sterilization effect. Besides, the garlic essential oil, the chitosan and the globe artichoke extract used in the fruit and vegetable fresh-keeping agent are all natural products extracted from plants, so the fruit and vegetable fresh-keeping agent is safe to use and free of any toxic and side effects, also has biological degradability and satisfies sanitation requirements.
Description
Technical field
The invention belongs to daily chemical products technical field, particularly relate to a kind of fruit and vegetable fresh-keeping agent.
Background technology
In daily life, fruit and vegetable is the daily necessities of people, but depositing of fruit and vegetable is a great problem, perplexs and affect the normal life of people.Fruit and vegetable is not easy to store is because fresh fruits and vegetables still carries out complicated physiological change, biological change and physical change after gathering, the biological cells and tissues of fruits and vegetables proceeds to breathe and transpiration, is easy to phenomenons such as producing shrinkage, weightlessness, wilting, go bad.In order to solve the fresh-keeping problem of fruits and vegetables, some fruit and vegetable fresh-keeping agents are there are on the market.
Fruit and vegetable fresh-keeping agent used at present is mainly divided into two large classes, i.e. chemical synthesis fruit and vegetable fresh-keeping agent and natural fruit vegetables antistaling agent.For a long time, people mainly adopt chemical synthesis fruit and vegetable fresh-keeping agent to the preserving fruit and vegetable utilizing of storage, although have good preservation and antisepsis effect, a lot of synthetics confrontation health has certain harm, serious even can make that people is carcinogenic, teratogenesis, mutagenic toxicity.
In view of this, necessaryly one natural fruit vegetables antistaling agent is safely and effectively provided, to solve the problem of antiseptic preservation of fruits and vegetables.
Summary of the invention
The object of the invention is to: one natural fruit vegetables antistaling agent is safely and effectively provided, to solve the problem of antiseptic preservation of fruits and vegetables.
In order to achieve the above object, the present invention adopts following technical scheme:
Fruit and vegetable fresh-keeping agent, by mass percentage, it comprises following component:
Galic essential oil 1% ~ 3%;
Shitosan 0.5% ~ 3%;
Organic solvent 2% ~ 20%;
Carlina acaulis extract 1% ~ 10%;
Surplus is sterilized water.
One as fruit and vegetable fresh-keeping agent of the present invention is improved, and by mass percentage, it comprises following component:
Galic essential oil 1.5% ~ 2.5%;
Shitosan 1% ~ 2%;
Organic solvent 5% ~ 15%;
Carlina acaulis extract 5%;
Surplus is sterilized water.
One as fruit and vegetable fresh-keeping agent of the present invention is improved, and it is characterized in that, by mass percentage, it comprises following component:
Galic essential oil 2%;
Shitosan 2%;
Organic solvent 10%;
Carlina acaulis extract 5%;
Surplus is sterilized water.
One as fruit and vegetable fresh-keeping agent of the present invention is improved, and described solvent is at least one in ethanol, acetic acid and ethyl acetate.
One as fruit and vegetable fresh-keeping agent of the present invention is improved, and its preparation method is: galic essential oil, shitosan, organic solvent and Carlina acaulis extract are added respectively in sterilized water, and homogeneous in homogenizer is then degassed, obtained fruit and vegetable fresh-keeping agent.
One as fruit and vegetable fresh-keeping agent of the present invention is improved, and its using method comprises the following steps:
The first step, removes the part that can not use of fruits and vegetables, cleans, is processed into solid content;
Second step, is immersed in 5min-40min in fruit and vegetable fresh-keeping agent by the solid content in the first step, then takes out solid content, drains in rear loading composite bed polybag, after vacuum seal, is placed in keeping fresh at normal temperature.
During use, from composite bed polybag, take out solid content, through clear water washing, substantially slough antistaling agent, make it to recover fresh fruit of vegetables taste.The method can prolong storage period 4-8 doubly.
Wherein, galic essential oil has antibacterial, sterilization, the effect of killing the virus, and galic essential oil and sulfur-bearing active component are wherein to human body, and the many pathogenetic bacterias of animal and plant have antagonistic activity.Galic essential oil is to 3 kinds of gram-positive coccis, and 7 kinds of gram-Negative bacilluses or vibrios have stronger bacteriostasis, and it can also suppress salmonella, the Growth and reproduction of Escherichia coli and Li bacillus.
Shitosan can form diaphragm on vegetables and fruits surface; and the rete formed has permeability, water preventing ability; penetration resistance can be increased to various gas molecule; define a kind of micro-controlled atmosphere environment; the in-house carbon dioxide content of fruits and vegetables is increased, and oxygen content reduces, and inhibits respiratory metabolism and the moisture loss of fruits and vegetables; slow down fruits and vegetables tissue and structure old and feeble, thus effectively extend fruits and vegetables adopt the rear life-span.In addition, shitosan has good antibacterial activity, can suppress the growth and breeding of some fungies, bacterium and virus.
Chlorogenic acid in Carlina acaulis extract, cynarin, Luteolin-7-rutinoside and cynara scolymus glucosides have higher antimicrobial, antimycotic and antibacterial activity.
Organic solvent and sterilized water composite, can improve dissolution evenness and the storage stability of whole antistaling agent.
Relative to prior art, the present invention, by the synergistic function of galic essential oil, shitosan and Carlina acaulis extract, can form on the surface of fruits and vegetables the protective film that one deck has permeability and water preventing ability, have good bactericidal action simultaneously.And the galic essential oil used in the present invention, shitosan and Carlina acaulis extract are all the natural products extracted from plant, use safety, without any side effects and there is biological degradability, salubrity requirement.
After carrying out fresh-keeping preservation with antistaling agent to fruits and vegetables, in freshness date, the taste, color and luster, nutritional labeling etc. of fruits and vegetables are all substantially constant, can keep the feeling of freshness of original fruits and vegetables.
