Description
Technical field
The present invention relates to litchi preserving technology, especially relate to a kind of pure natural antistaling agent for litchi.
Background technology
Existing antistaling agent for litchi adopts the material of chemical synthesis more, along with the prolongation of storage life, penetrates into easily in the pulp, and there is certain harm in health.
Summary of the invention
For solving above technical problem, the purpose of this invention is to provide a kind of pure natural antistaling agent for litchi.
Technical scheme of the present invention is: a kind of pure natural antistaling agent for litchi is grouped into by the one-tenth of following percentage by weight: aloe extract 4 ~ 6%, and acetate buffer solution 8 ~ 12%, shitosan 2 ~ 3%, all the other are distilled water.
The preparation method of described aloe extract is: aloe is cleaned squeezed the juice, added acetate buffer solution lixiviate 6 ~ 8 hours, 4000rpm centrifuging and taking supernatant by weight 1: 1.
The ion concentration of described acetate buffer solution is 1mol/L, and the pH value is 4.5.
The deacetylation of described shitosan is 70 ~ 80%.
The invention has the beneficial effects as follows: green, environmental protection, extraction and easy to use, cost is low, and good refreshing effect has broad application prospects.
The specific embodiment
Embodiment 1
Aloe cleaned squeeze the juice, added acetate buffer solution by weight 1: 2, ion concentration is 1mol/L, the pH value is 4.5, lixiviate 6 ~ 8 hours, 4000rpm centrifuging and taking supernatant adds half shitosan of aloe quality again, the deacetylation of shitosan is 70 ~ 80%, and the distilled water diluting that adds at last 20 times of aloe weight gets final product.
The above is not to be limitation of the present invention, and every technical solution of the present invention content that do not break away to any simple modification, equivalent variations and remodeling that above embodiment does, still belongs to the protection domain of technical solution of the present invention according to technical spirit of the present invention.
