Abstract
The invention relates to a biological source strawberry preservative. The biological source strawberry preservative is characterized by comprising the following main components: 0.1-0.5g/L of wood vinegar, 0.2-0.5g/L of glutamic acid, 0.2-0.5g/L of arginine, 0.1-0.5g/L of ascorbic acid, 5-10g/L of chitosan and the balance of water. A preparation method comprises the following steps: firstly dissolving the ascorbic acid in water, further sequentially adding the chitosan, the wood vinegar, the glutamic acid and the arginine and the balance of water. By using the preservative to soak or coat strawberry fruits for 1-3 minutes, the preservative has a better preservative effect on strawberries after airing, can prolong the storage period and the shelf life and has good application prospects.
Description
Technical field
The present invention relates to a kind of fruit antistaling agent, especially a kind of biogenic strawberry preservative, belong to the Food Engineering Development field.
Background technology
Strawberry is the perennial fruit tree of rose family Fragaria, often does annual cultivation.Due to outstanding economic benefit, its development speed is very fast in recent years, becomes the pillar industry of some areas, huge to driving the increasing peasant income effect of getting rich.But strawberry fruit is very easily damaged, not anti-ly store transportation, so made extensive work around the fresh-keeping of strawberry and storage research in the industry, the biologic product exploitation antistaling agent of application safety is a very important content wherein, significant to the development of Strawberry industry.
Pyroligneous liquor is the condensate recovery liquid of thermal decomposition of wood composition in firing the charcoal process, has special sootiness smell, is acid, for faint yellow to bronzing.Constituent contains the little molecule organic principle of kind more than 200, is mainly organic acid, phenols, ketone, alcohols and ester class.Wherein take acetic acid as main component, occupy 50% left and right of machine composition.Glutamic acid and arginine are one of ubiquitous amino acid in organism, and ascorbic acid is a kind of water soluble vitamin, rich content in fruits and vegetables.
At present, not yet find take that pyroligneous liquor, glutamic acid, arginine, ascorbic acid, shitosan are main component, prepare antistaling agent, for extending the documents and materials report of Storage of Strawberry phase and shelf life.
Summary of the invention
The present invention is directed to the deficiency of existing antistaling agent technology, a kind of biogenic strawberry preservative is provided, can effectively extend Storage of Strawberry phase and shelf life, improve commodity value and economic benefit, there are good Application and Development potentiality.
Simultaneously, the present invention also provides a kind of and uses above-mentioned antistaling agent strawberry to be carried out to the method for Preservation Treatment.
The present invention completes by following technical proposal: a kind of biogenic strawberry preservative, it is characterized in that, its main component is: pyroligneous liquor 0.1 ~ 0.5g/L, glutamic acid 0.2 ~ 0.5g/L, arginine 0.2 ~ 0.5g/L, ascorbic acid 0.1 ~ 0.5g/L, shitosan 5 ~ 10g/L, all the other are water.
The present invention also provides preparation and the using method thereof of biogenic strawberry preservative, it is characterized in that, ascorbic acid is first soluble in water, then adds successively shitosan, pyroligneous liquor, glutamic acid, arginine, supplies surplus moisture, stirs.Soak or strawberry fruit 1 ~ 3min is processed in coating with this antistaling agent, dry and rear strawberry is had to fresh-keeping effect preferably, extend storage period and shelf life.
The invention has the beneficial effects as follows: biogenic strawberry preservative provided by the present invention has fresh-keeping effect preferably to strawberry, extends storage period and shelf life, and required raw material is biogenic product, safe.Raw material is bought convenient, and preparation technology and using method are simple, have good development prospect.
The specific embodiment
In order to make purpose of the present invention, technical scheme and advantage clearer, the present invention describes with following specific embodiment, but the present invention is limited to absolutely not these examples.
Embodiment 1: pyroligneous liquor 0.2g/L, glutamic acid 0.2g/L, arginine 0.5g/L, ascorbic acid 0.5g/L, shitosan 5g/L, and ascorbic acid is first soluble in water, then add successively shitosan, pyroligneous liquor, arginine, and supply surplus moisture, stir.Soak or coating processing strawberry fruit 2 min with this antistaling agent, dry rear storage.With clear water in contrast.After 7 days, investigation result shows: the contrast fruit weight-loss ratio really rate of becoming reconciled is respectively 13.9%, 0, and the present embodiment invention antistaling agent is processed the fruit weight-loss ratio really rate of becoming reconciled and is respectively 8.1%, 72.3%.Visible, antistaling agent of the present invention is processed can significantly improve strawberry fruit storage period quality.
