Technical field
The present invention relates to fruit freshness preserving technical field, and in particular to a kind of long-acting fruit antistaling agent and preparation method thereof.
Background technology
China has abundant coal resources, wherein 1/3 or so is low-order coal, low-order coal is also referred to as colm, generates heat
Amount is relatively low, without fuel value, makes them unsuitable for the fuel that is used as power, often discarded object is used as in coal mining.Low-order coal is
The important source material that coal is converted and chemical process is utilized.In the prior art for the utilization of low-order coal, mainly as coking, refining
The raw material of oil, gasification, low temperature distillation and chemical industry etc., the wherein grading process such as coking, oil refining, gasification, low temperature distillation for
The utilization of low-order coal is not thorough, and different degrees of pollution can be caused to environment.
Low-order coal is the main source of coal humic acid.Humic acid is the unbodied macromolecule organic of a class, is by dead
Die biological substance to produce through microbial degradation, be widely present in the low-order coals such as the lignite, weathered coal, peat of nature and soil
In.Humic acid it is widely used, may be used as water treatment agent, coal water mixture stabilizing agent, petroleum assistant etc., humic acid is used as in recent years
Plant growth substance is even more obtained extensive research and application.Although humic acid also has the function of antistaling agent, at present will
It is directly applied on fruit freshness preserving also seldom.
Plants essential oil is the secondary metabolites in plant, is made up of the relatively small simple compounds of molecular weight, tool
There is certain aromatic odor, be the oily liquids material that can be volatilized at normal temperatures.Using containing in spice berry extract essential oil
A variety of low molecular antibacterial materials and antioxidant content, can effectively antibacterial anti-corrosion as fruits and vegetables class crude antistaling agent.Therefore plant
Effect of the thing essential oil on preserving fruit and vegetable utilizing increasingly causes the concern of people.But plants essential oil has high volatility, volatilization is fast
And because be liquid without it is easy to maintain the characteristics of, therefore be subject to certain restrictions as the mode of fruit and vegetable fresh-keeping agent, and fresh-keeping effect
It is not lasting.
The content of the invention
In view of the defect of above-mentioned prior art, the technical problem to be solved in the present invention is to provide a kind of long-acting fruit freshness preserving
Agent and preparation method thereof.The antistaling agent is, using low-order coal and plants essential oil as primary raw material, and to take full advantage of coal resources, is subtracted
Few pollution to environment, its fresh-keeping effect is also preferably and persistent.
In view of the above-mentioned technical problem to be solved, the present invention provides following technical solution：
A kind of long-acting fruit antistaling agent, including following parts by weight of component：10-25 parts of low-order coal, sodium bicarbonate aqueous solution 30-38
Part, 10-25 parts of porous-starch, 2-6 parts of sucrose ester, 1-5 parts of emulsifying agent, 2-5 parts of plants essential oil, 1-3 parts of acetic acid, chitosan 2-5
55-65 parts of part and water.
It is preferred that, the antistaling agent includes following parts by weight of component：It is 22 parts of low-order coal, 34 parts of sodium bicarbonate aqueous solution, many
60 parts of 18 parts of hole starch, 25 parts of sucrose ester, 3 parts of emulsifying agent, 4 parts of plants essential oil, 2 parts of acetic acid, 4 parts of chitosan and water.
It is preferred that, the low-order coal is any of peat, lignite or weathered coal.
It is preferred that, the emulsifying agent is Tween-80.
It is preferred that, the plants essential oil is cinnamon essential oil, Rosa Damascana, cherry essence, lemon or Rosemary Oil
In the mixed essential oils that are mixed with arbitrary proportion of one or more.
Present invention also offers a kind of method for preparing above-mentioned long-acting fruit antistaling agent, comprise the following steps：
（1）Each raw material is weighed by the weight point；
（2）Low-order coal is crushed to 150-400 mesh, concentration is added and reacts 2-5 hours systems for 5% sodium bicarbonate aqueous solution
Standby sodium humate；
（3）The sodium humate that above-mentioned steps are obtained is purified and removed alternately through macroreticular resin and strong ion exchange resin
Heavy metal element, is purified and is removed the sodium humate after heavy metal element；The sodium humate and macroreticular resin and by force from
The mass ratio of sub-exchange resin is 1：10-20：15-25；
（4）The porous-starch and water are added in there-necked flask, electric mixer stirring is started, in rotating speed 600r/min-
25min-45min is stirred under conditions of 1200r/min, the sucrose ester and emulsifying agent is then respectively adding, is in rotating speed
Continue to stir 30min-50min under conditions of 1200r/min-1500r/min, then be separately added into the plants essential oil, in rotating speed
Continue to stir 50min-80min under conditions of 2000r/min-3000r/min, be eventually adding the acetic acid and chitosan, turning
Speed is continuation stirring 10min-15min under conditions of 2000r/min-3000r/min, and 25 DEG C -28 is placed in after taking out vacuum filtration
In DEG C vacuum drying chamber, vacuum is to dry 36h-48h under the conditions of -0.085MPa--0.095MPa, obtains plants essential oil fresh-keeping
Agent；
（5）By step（3）Sodium humate and step after the purified and removing heavy metal element of middle acquisition（4）The plant of middle acquisition
Thing essential oil fresh is well mixed, long-acting fruit antistaling agent needed for producing.
It is preferred that, the step（3）Sodium humate after middle purifying and removing heavy metal element, wherein dry weight sodium humate
