Description
Technical field
The present invention relates to low-temperature instant agar more particularly to a kind of preparation methods of low-temperature instant agar.
Background technology
Agar is the polysaccharide body by being extracted in seaweed, is current one of widest algin of purposes in the world.It is eating
Many aspects such as product industry, medical industry, daily-use chemical industry, bioengineering have a wide range of applications, and agar is used for can be bright in food
The aobvious quality for changing food, improves the class of food.There is agar coagulability, stability can form complex compound with some substances,
It can be used as thickener, coagulator, suspending agent, emulsifier, antistaling agent and stabilizer.For manufacturing beverage, jelly, ice cream, cake
Point, soft sweets, can, meat products, mixed congee, white fungus bird's nest, custard based food, stir-fried food etc..Agar on medical research,
It can make culture medium, ointment base.
But conventional agar is generally under the high temperature conditions（95 DEG C or more）, just it was completely dissolved, is heating at 10-15 minutes
High temperature and longer time are needed when dissolving, the big defect of one when becoming its application.With the fast development of food industry, to property
The demand of the excellent agar of energy is also increasingly come urgently, how to prepare a kind of agar of low solution temperature, become this field urgently
Problem to be solved.
Invention content
The present invention is in view of the above problems, propose a kind of preparation method of low-temperature instant agar.
The present invention is achieved by the following technical solutions, includes the following steps：
（1）Agar powder and microcrystalline cellulose are mixed, by ball mill wet-milling, obtain agar fine powder；
（2）Into the water by agar fine powder, it is heated to agar fine powder solubility or more to dissolve, obtains the fine jade for being mixed with microcrystalline cellulose
Fat Polymer Solution；
（3）Agar Polymer Solution is handled by high-tension apparatus,；
（4）Centrifugal treating is carried out to the discharging that high-tension apparatus is handled, obtains agar macromolecule clear solution；
（5）Agar macromolecule clear solution is spray-dried, ice-cold preservation obtains low-temperature instant agar.
Preferably, the centrifugal treating carries out under heat preservation, and temperature is not less than agar solidification point.
Preferably, the centrifugal treating uses the rotating speed of centrifuge for 4500 ~ 5000rpm.
Preferably, the time of the centrifugal treating is 5-10min.
Preferably, described to be centrifugally separating to obtain microcrystalline cellulose and part agar batch mixing, emulsifier is added, is set by high pressure
Standby processing obtains the emulsion for being mixed with microcrystalline cellulose, and stratification removes microcrystalline cellulose, obtains agar emulsion, and centrifugation is broken
Supernatant is gone to be spray-dried after breast, ice-cold preservation obtains low-temperature instant agar, recycles extra agar batch mixing, avoids wasting.
Preferably, the emulsifier is Tween-80.
Preferably, the temperature of the ice-cold preservation is -40 ~ -35 DEG C, time at least 48h.
Preferably, the high-tension apparatus uses high pressure homogenizer or mulser, pressure 40-150MPa.
Cellulose depolymerization product of the microcrystalline cellulose as food-grade, is the presence of odorless, tasteless, not shadow is mixed with agar
Ring final product, and microcrystalline cellulose the present invention as a kind of presence of similar grinding aid, on the one hand, microcrystalline cellulose cooperation
Agar wet-milling can obtain thinner agar fine powder, and be avoided that agar fine powder paste ball paste mill, in addition, microcrystalline cellulose is insoluble in
The removal of water and emulsifier, follow-up microcrystalline cellulose is also more thoroughly effective.
The present invention obtains thinner agar fine powder by microcrystalline cellulose and agar powder wet-milling first, passes through height after dissolving again
Pressure equipment further refines, and is centrifugally separating to obtain agar macromolecule clear solution using the difference of molecular size range, finally sprays
Dry further refinement, ice-cold preservation make it have better crystalline form to dissolve, obtain final low-temperature instant agar.Because crystallite is fine
Dimension element is insoluble in emulsifier, and the microcrystalline cellulose and part agar centrifuged out further detaches under the action of emulsifier,
Then by centrifuging the removal emulsifier that is demulsified, after spray drying, ice-cold preservation, which is recycled, obtains remaining agar fine powder, reduces waste.
The production technology of the present invention has the following advantages that：According to Noyes Whitney equations, since grain diameter reduces
Caused specific surface area increases and high wettability, can promote the quick dissolving of particle.Mixed microcrystalline cellulose carries out wet-milling, subtracts
The absorption inside agar after refining is lacked, has improved wet-grinding efficiency, obtain thinner agar fine powder.High-tension apparatus processing and spraying are dry
It is dry, agar can be further refined, the ice-cold preservation of 48h or more can change the crystal form of agar fine powder, be conducive to dissolving, obtain height
The agar powder of specific surface area.
It is good that the present invention obtains agar dissolubility, solution temperature≤60 DEG C, and dissolves rapid.Meanwhile present invention process is simple,
It is high to centrifuge obtained agar batch mixing reuse ratio, less, commercial viability is strong for waste.
Specific implementation mode
This specific implementation method is only explanation of the invention, is not limitation of the present invention.People in the art
Member's any change made after the specification for having read the present invention, as long as in the range of claims, it all will be by
To the protection of Patent Law.
