Description

A kind of guava antistaling agent and preparation method thereof
Technical field
The present invention relates to a kind of guava antistaling agents and preparation method thereof.
Background technology
Guava (Psidium guajava Linn.) is Myrtaceae Psidium evergreen shrubs or dungarunga, is originated in Tropical America is the fruit tree that each torrid zone in the world and subtropical zone are cultivated extensively now.Breathing after guava fruit harvesting becomes Change and belong to transition type, and the time of occurrence of transition phase is unrelated with maturity when harvesting, 4~6d reaches CO after harvesting2With The transition peak of ethylene, this is one of the reason of guava is difficult to preservation and freshness.Its pericarp is thin and brittle, is picking and pole in transportational process It is easily bruised and virus infection, generation is rotted, the shelf-life at normal temperatures only has 2~7d, is stored at 10 DEG C or less, it may appear that cold Evil symptom.In addition, guava is adopted, rear low water is serious, and hardness declines rapidly, not storage tolerance, seriously affects the edible of guava fruit Quality and commodity value.Therefore, the preservation and freshness of guava becomes assistant officer's problem to be solved in guava production and sales.
Postharvest handling is the important link of fruit freshness preserving.The most important preservation and freshness mode of guava is refrigeration at present, Secondary is air conditioned storage.Though deepfreeze or air conditioned storage can extend the freshness date of guava, equipment investment is big, costly.Closely Nian Lai, chemical preservative and fungicide are used widely, but be there is pollution environment, influenced the defects of health.With Demand of the people to pollution-free food seeks nontoxic, noresidue Perserving materials, it has also become the hot spot of fruit freshness preserving research.
But currently, Chinese herbal medicine preservative fails to obtain commercial applications, main cause may be due in the antistaling agent of part Used medicinal herb components are complicated, and active constituent content therein and the mechanism of action are still not clear, medicine source, content and preparation The stability of itself is not easy to solve, and certain Chinese herbal medicines, there is also special smell, differ surely public when large dosage is used Received;Secondly, do not have industrialized condition also with mass production for the extraction of the active ingredient of antistaling agent in Chinese herbal medicine.

Further, the starch in cornstarch, potato starch, sweet potato powder, tapioca starch, kudzuvine root starch at least one Kind.
Application of the antistaling agent described in any one of the above embodiments in guava is fresh-keeping.
A kind of preparation method of guava antistaling agent, includes the following steps:
The preparation of extracts of Chinese herbal medicine:It weighs dandelion, hawthorn, Radix Glycyrrhizae, folium isatidis and is added to the water 1.5~2.5h of immersion Afterwards, it boils and decocts 25~50min, collect filtrate, filter residue is opened with boiling again and decocts 15~35min, filtrate is collected, before and after merging 2 filtrates, obtain extracts of Chinese herbal medicine;Chinese herbal medicine total amount used in every liter of extracts of Chinese herbal medicine is 95~115g, wherein Chinese herbal medicine Pu Public English, hawthorn, Radix Glycyrrhizae and the amount ratio of folium isatidis are as described above;
The preparation of starch fluid:Starch is boiled into obtain starch fluid with boiling;The content of starch is 25~50g/ wherein in starch fluid L;
By volume (0.8~1.2) by said herbal medicine extracting solution and starch fluid:(0.8~1.2) it mixes, obtains guava Antistaling agent;
Further, above-mentioned starch in cornstarch, potato starch, sweet potato powder, tapioca starch, kudzuvine root starch at least one Kind.
The guava antistaling agent that any of the above-described the method is prepared.
A kind of method of fresh-keeping guava, guava is placed in above-mentioned guava antistaling agent, is impregnated 1.5~2.5h, is dried in the air It is dry.
The beneficial effects of the invention are as follows:
1, antistaling agent of the invention is that, for the fresh-keeping of guava, can be kept using Chinese herbal medicine as the crude antistaling agent of raw material The color, smell and taste and structural state of fruit, fresh keeping time is long, has no toxic side effect.
2, antistaling agent of the present invention can effectively reduce scattering and disappearing for fruit surface moisture, maintain the higher nutritional ingredient of vegetables and fruits, prolong Fruits and vegetables maturing process is grown.
3, through the fresh-keeping vegetables and fruits of antistaling agent of the present invention, the light natural scents with Chinese herbal medicine, unique flavor has battalion Support health value.
