Description
Technical field
The present invention relates to low-temperature instant agar, more particularly to a kind of preparation method of low-temperature instant agar.
Background technology
Agar has that quality is hard, heat resistance strong, stablize in acid condition in food applications, with food it is other into
Divide reactionless.Exactly these advantages cause agar to apply always in many food, especially hard, good thermally-stabilised in needs
Property and good Moisture stability food in there is the status do not replaced.But, conventional agar is general under the high temperature conditions(95
More than DEG C), just it was completely dissolved at 10-15 minutes, high temperature and longer time is needed when dissolving by heating, when being applied as it
One big defect.Although some reduce solution temperature by modified agar, but the gel strength decline of agar is very big so that fine jade
The advantage of fat is no longer obvious.How to design a kind of low melting point and the high low-temperature instant agar of gel strength is that the present invention to be solved
Technical problem.
The content of the invention
The technical problems to be solved by the invention are:A kind of preparation method of low-temperature instant agar is provided, realized in reduction
On the premise of the fusing point of low-temperature instant agar so that low-temperature instant agar has stronger gel strength.
The technical scheme that the present invention is provided is that a kind of preparation method of low-temperature instant agar comprises the following steps:
Step 1: agar powder and water are mixed, it is heated at high temperature to and is completely dissolved, forms agar solution;
Step 2: above-mentioned agar solution is carried out into ultrasonication;
Step 3: adding cosolvent in the solution obtained toward step 2, fully dissolving stirs;
Step 4: the solution that step 3 is obtained passes through high-pressure homogeneous processing;
Step 5: the solution that step 4 is obtained carries out granulation processing;
Step 6: sieving, is made low-temperature instant agar.
Compared with prior art, advantages and positive effects of the present invention are:The system for the low-temperature instant agar that the present invention is provided
Preparation Method, by the effect of ultrasonic wave, opens the helical structure of agar, and adds certain cosolvent, promotes agar can be short
Dissolved rapidly in time, and with certain gel strength;The agar solution temperature being modified by this method is relatively low, in 75-
80 DEG C, industrial input is saved, substantial amounts of time and the energy has been saved, has improved production efficiency;This method is simple, easy
Operation, feasibility is very strong in the industrial production;The agar being modified by this method, intensity is not reduced a lot, can meet production
On for gel strength requirement;The agar being modified by this method, dissolution velocity is very fast, can be between 75-80 DEG C, in short-term
Interior rapid dissolving.
Embodiment
The present invention provides a kind of preparation method of low-temperature instant agar, it is characterised in that comprise the following steps:
Step 1: agar powder and water are mixed, it is heated at high temperature to and is completely dissolved, forms agar solution.Specifically, by agar powder with
Water is according to mass ratio(1-20):(80-99)Ratio mixing after, high-temperature heating dissolving form agar solution.
Step 2: above-mentioned agar solution is carried out into ultrasonication.Specifically, the power of ultrasonic unit>800W, frequency
>100KHz;Also, in ultrasonication, holding temperature is 40-90 DEG C, processing time 0.5-8 hour.
Step 3: adding cosolvent in the solution obtained toward step 2, fully dissolving stirs.Specifically, cosolvent
Including one or more mixtures in salt, sugar, emulsifying agent and edible colloid.Salt can be sodium salt, sylvite or phosphate, institute
It can be sucrose, glucose, xylose, xylitol or dextrin to state sugar;The emulsifying agent is sucrose ester or this Pan;Edible colloid can be with
Be carragheen, konjac glucomannan, sodium alginate, xanthans, carboxymethyl cellulose, guar gum, Sodium Polyacrylate, gelatin, curdlan,
Gellan gum or Arabic gum;The addition of cosolvent is agar weight(0.1-40):(60-99.9).
Step 4: the solution that step 3 is obtained passes through high-pressure homogeneous processing.Specifically, high-pressure homogeneous>100MPa.
Step 5: the solution that step 4 is obtained carries out granulation processing.Specifically, the solution obtained to step 4 is made
Grain can be using spraying or precipitation filtering two ways.For example:The solution that step 4 is obtained directly carries out mist projection granulating, its
In, it is spray-dried feeding temperature<90 DEG C, EAT>100 DEG C, leaving air temp>70℃;Or, by the solution of above-mentioned steps four
Precipitating reagent is added, centrifugal filtration, drying and crushing is granulated, wherein, precipitating reagent can be one kind of ethanol, isopropanol, acetone
Or it is a variety of;Precipitating reagent and the solution of step 3 are with 3:1-5:1 ratio mixing carries out centrifuge filtering, and in 30-50 DEG C of temperature
Lower drying.
Step 6: sieving, is made low-temperature instant agar.
The invention is not limited in above-mentioned embodiment, if the various changes or modification to the present invention do not depart from the present invention
