Problems solved by technology

However, conventional agar generally dissolves completely in 10-15 minutes under high temperature conditions (above 95°C), and requires high temperature and long time for heating and dissolving, which has become a major defect in its application.
Although some modified agars have lowered the dissolution temperature, the gel strength of the agars has dropped greatly, making the advantages of agars no longer obvious

Embodiment Construction

[0012] The invention provides a kind of preparation method of low-temperature instant agar, is characterized in that, comprises the steps:

[0013] Step 1. Mix agar powder and water, heat at high temperature until completely dissolved, and form an agar solution. Specifically, the agar powder and water are mixed according to a mass ratio of (1-20): (80-99), and then heated and dissolved at high temperature to form an agar solution.

[0014] Step 2, the above-mentioned agar solution is subjected to ultrasonic treatment. Specifically, the power of the ultrasonic device is >800W, and the frequency is >100KHz; and, during the ultrasonic treatment, the holding temperature is 40-90° C., and the treatment time is 0.5-8 hours.

[0015] Step 3: Add co-solvent to the solution obtained in Step 2, fully dissolve, and stir evenly. Specifically, the co-solvent includes a mixture of one or more of salt, sugar, emulsifier and edible colloid. Salt can be sodium salt, potassium salt or phosph...

Abstract

The invention discloses a preparation method of low-temperature quick-soluble agar. The method comprises the following steps: 1, mixing agar powder with water to obtain a mixture, and heating at high temperature until the mixture is completely dissolved to form an agar solution; 2, carrying out ultrasonic treatment of the agar solution; 3, adding cosolvent into the solution obtained in the step 2, fully dissolving and evenly stirring; 4, carrying out high pressure homogenization treatment of the solution obtained in the step 3; 5, carrying out granulation treatment of the solution obtained in the step 4; and 6, sieving to prepare the low-temperature quick-soluble agar. Under the premise of reducing a melting point of the low-temperature quick-soluble agar, the low-temperature quick-soluble agar has relatively strong gel strength.

Description

technical field [0001] The invention relates to low-temperature instant agar, in particular to a preparation method of low-temperature instant agar. Background technique [0002] In food applications, agar has a hard texture, strong heat resistance, stable under acidic conditions, and has no reaction with other ingredients in food. It is these advantages that make agar has been used in many foods, especially in foods that require firmness, good heat stability and good moisture stability. However, conventional agar generally dissolves completely in 10-15 minutes under high temperature conditions (above 95°C), and requires high temperature and long time for heating and dissolving, which has become a major defect in its application. Although the dissolution temperature of some modified agars has been reduced, the gel strength of the agars has dropped greatly, making the advantages of the agars no longer obvious. How to design a low-temperature instant agar with low melting po...
