Abstract
The invention discloses a sugar orange film antistaling agent, which is composed of sodium alginate, monoglyceride, calcium hydroxide, diflumetorim, trifloxystrobin and water, wherein, the mass concentration of the sodium alginate is 3-5%, the mass concentration of monoglyceride is 0.2-0.5%, the mass concentration of calcium hydroxide is 0.03-0.05%, the mass concentration of diflumetorim is 0.0002-0.0004%, and the mass concentration of trifloxystrobin is 0.0001-0.0002%. The sugar orange film antistaling agent provided by the invention is convenient to use and low in cost, can avoid the cold resistant pathogenic bacteria generated during refrigeration fresh storage. The film formed on a sugar orange surface can inhibit respiration of the sugar orange and growth of surface pathogenic bacteria and prevent decay. After 100 days, the bad fruit rate is less than 4%, and the water loss rate is less than 10%. A fresh taste can be kept. With good stability, the film antistaling agent cannot deteriorate after 6-month storage, and the formed film has strong adhesion.
Description
Technical field
The invention belongs to field of fruit freshness keeping, be specifically related to a kind of sugar orange coating antistaling agent.
Background technology
Sugar orange be a kind of main product in southern tropical fruit (tree), after harvesting north transport or storage in, if do not carried out Preservation Treatment, as easy as rolling off a log because of breathe or remained on surface harmful bacteria and cause the rapid deterioration of sugar orange rot.Existing preservation method mostly is refrigeration, but refrigeration cost is higher, and easily produces cold-resistant pathogenic bacteria.
Summary of the invention
The technical problem to be solved in the present invention overcomes existing defect, provides a kind of sugar orange coating antistaling agent and preparation method thereof.
In order to solve the problems of the technologies described above, the invention provides following technical scheme:
A kind of sugar orange coating antistaling agent, be made up of sodium alginate, monoglyceride, calcium hydroxide, fluorine mepanipyrim, oxime bacterium ester and water, wherein, the mass concentration of sodium alginate is 3 ~ 5%, the mass concentration of monoglyceride is 0.2 ~ 0.5%, the mass concentration of calcium hydroxide is 0.03 ~ 0.05%, and the mass concentration of fluorine mepanipyrim is 0.0002 ~ 0.0004%, and the mass concentration of oxime bacterium ester is 0.0001 ~ 0.0002%.
The preparation method of described sugar orange coating antistaling agent, is first added to the water sodium alginate, is heated to 40 ~ 50 DEG C, then adds monoglyceride, stirs and obtains emulsion, then in emulsion, add fluorine mepanipyrim, oxime bacterium ester and calcium hydroxide.
The present invention is easy to use, and adult is low, can avoid the cold-resistant pathogenic bacteria produced during cold storing and fresh-keeping, the film formed on sugar orange surface can suppress the growth of the breathing of sugar orange and surperficial germ, prevent from rotting, the bad fruit rate after 100 days is less than 4%, percentage of water loss is less than 10%, keep taste fresh.This coating antistaling agent is stablized, and can deposit and never degenerate half a year, and the adhesive force of formation is strong.
Detailed description of the invention
Below the preferred embodiments of the present invention are described, should be appreciated that preferred embodiment described herein is only for instruction and explanation of the present invention, is not intended to limit the present invention.
embodiment 1
By the coating antistaling agent of 1000g, first the sodium alginate of 30g is added to the water, be heated to 40 DEG C, then the monoglyceride of 2g is added, stir into uniform emulsion, and then add the calcium hydroxide of the fluorine mepanipyrim of 0.002g, the oxime bacterium ester of 0.002g and 0.3g, stir 30 minutes, namely obtain sugar orange coating antistaling agent.During use, sugar orange coating antistaling agent is sprayed in sugar orange, airing, obtains thin film on sugar orange surface.
embodiment 2
By the coating antistaling agent of 1000g, first the sodium alginate of 40g is added to the water, be heated to 40 DEG C, then the monoglyceride of 3g is added, stir into uniform emulsion, and then add the calcium hydroxide of the fluorine mepanipyrim of 0.004g, the oxime bacterium ester of 0.001g and 0.4g, stir 30 minutes, namely obtain sugar orange coating antistaling agent.
embodiment 3
By the coating antistaling agent of 1000g, first the sodium alginate of 50g is added to the water, be heated to 48 DEG C, then the monoglyceride of 5g is added, stir into uniform emulsion, and then add the calcium hydroxide of the fluorine mepanipyrim of 0.003g, the oxime bacterium ester of 0.002g and 0.5g, stir 30 minutes, namely obtain sugar orange coating antistaling agent.
Last it is noted that the foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, although with reference to previous embodiment to invention has been detailed description, for a person skilled in the art, it still can be modified to the technical scheme described in foregoing embodiments, or carries out equivalent replacement to wherein portion of techniques feature.Within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
