Description
Technical field
The present invention relates to a kind of fruit and vegetable fresh-keeping agent, belong to postharvest technology of fruits and vegetables field.
Background technology
After fruit and vegetable picking, usually carry out the process such as classification, packaging, cleaning, drying, waxing, chemicals be fresh-keeping, then carry out transport circulation.Along with the fast development of China's agricultural production, the fruits and vegetables series products that increasing agricultural product are particularly perishable, all need to carry out after adopting, in the field of circulation fast, low energy consumption, low cost and the place of production fresh-keeping.
Carry out metabolism by respiration after fruit and vegetable picking, excessive, fast respiration make fruits and vegetables faster metabolism, loss of life activity energy gradually, old and feeble gradually, occurs softening, shrivelled, coming off ought.Therefore, often through at fruit and vegetable surfaces spraying antistaling agent, respiration is suppressed as the film forming matters such as wax, resinae, gelatin, starch form one protecting film at fruit and vegetable surfaces.This kind of antistaling agent can be the aqueous solution of emulsion or debita spissitudo.
Existing antistaling agent, as excessive interpolation preservative ingredient, easily brings potential harm to consumer, the existing research and development tending to crude antistaling agent more.Moringa seeds water-retaining property is strong, the active material of the cosmetics of super quality such as being mainly used as fluid purification in fields such as food, medicine, health care, cosmetics, extracting manufacture water conservation, be sun-proof.Moringa seeds contains raw alkaloid, and biologically active is high.Moringa seeds is also rich in seed oil of Moringa oleigera, has and reduces blood sugar, improving water flood, gut purge and the function that enhances metabolism.
Summary of the invention
The object of this invention is to provide a kind of fruit and vegetable fresh-keeping agent, containing seed oil of Moringa oleigera in its formula, natural plant active component is utilized to increase the water-retaining property of fruits and vegetables, simultaneously active antibacterial ingredient wherein can play antibacterial, antibacterial effect, natural film forming matter suppresses fruits and vegetables respiratory metabolism, extends preserving fruit and vegetable utilizing phase and shelf life.
Technical scheme of the present invention is as follows: a kind of fruit and vegetable fresh-keeping agent, is made up of seed oil of Moringa oleigera 10 ~ 30 parts, chitosan solution 30 ~ 60 parts, the ethanolic solution 5 ~ 50 parts of mass fraction 45 ~ 60%, potassium sorbate 0.5 ~ 5 part, emulsifying agent 1 ~ 10 part, 10 ~ 800 parts, water.
Preferred compositing formula can be: seed oil of Moringa oleigera 22 parts, chitosan solution 35 parts, the ethanolic solution 35 parts of mass fraction 45 ~ 60%, potassium sorbate 0.5 part, emulsifying agent 2 parts, 320 parts, water.
Preferred compositing formula can also be further: seed oil of Moringa oleigera 18 parts, chitosan solution 45 parts, the ethanolic solution 40 parts of mass fraction 45 ~ 60%, potassium sorbate 1 part, emulsifying agent 5 parts, 580 parts, water.
Preferred compositing formula can also be further: seed oil of Moringa oleigera 30 parts, chitosan solution 60 parts, the ethanolic solution 50 parts of mass fraction 45 ~ 60%, potassium sorbate 3 parts, emulsifying agent 10 parts, 700 parts, water.
The preparation method of described seed oil of Moringa oleigera is as follows: get moringa seeds, is crushed to 80 ~ 100 orders, adds mass fraction 45 ~ 60% ethanolic solution, in 60 ~ 80 DEG C of extracting 60 ~ 90min, gets distillate.
The mass fraction of described chitosan solution is 2 ~ 8%.
Described emulsifying agent can be the one in twain series emulsifier or Span series emulsifying agent.
The preparation method of fruit and vegetable fresh-keeping agent of the present invention is: be first dissolved in the water by potassium sorbate, obtains potassium sorbate solution; Stir potassium sorbate solution limit with rotating speed 400 ~ 1000r/min limit again and add chitosan solution wherein, stir 10 ~ 30min, add seed oil of Moringa oleigera, continue stirring 10 ~ 30min, drip emulsifying agent, mixing and emulsifying is pulverized evenly.
The present invention is as follows relative to the beneficial effect of prior art: containing seed oil of Moringa oleigera in its formula of fruit and vegetable fresh-keeping agent of the present invention, natural plant active component is utilized to increase the water-retaining property of fruits and vegetables, simultaneously active antibacterial ingredient wherein can play antibacterial, antibacterial effect, natural film forming matter suppresses fruits and vegetables respiratory metabolism, extends preserving fruit and vegetable utilizing phase and shelf life.Relative to existing chemical preservative, fruit and vegetable fresh-keeping agent safety non-toxic of the present invention, preparation method is simple, and fresh-keeping effect is good.
