Embodiment 1

[0019] Take 10g of agar powder, 1g of sucrose, add 1kg of water, boil for several minutes until completely dissolved. Stop heating, take it out, freeze and store until it is completely frozen, thaw it naturally at room temperature, dehydrate it with a plate basket filter press, spray the pre-configured 1% lecithin on the surface of the dry object in a forest-spraying method, and dry it under natural conditions . Grind and sieve with a 100-mesh pulverizer to obtain instant agar.

[0020] The product characteristics are as follows: Dissolving speed: 15 minutes at 80°C, 2 minutes at 90°C.

Embodiment 2

[0022] Take 20g of agar powder, 5g of sucrose, add 1kg of water, boil for several minutes until completely dissolved. Stop heating, take it out, freeze and store until it is completely frozen, thaw naturally at room temperature, dehydrate with a plate basket filter press, dry in a dryer at a drying temperature of 50°C, count for 3 hours, cool down to around 30°C, and pre-configure A good 5% lecithin is sprayed onto the surface of the dry object in a spray forest, and timed for 1 hour. Grind and sieve with a 100-mesh pulverizer to obtain instant agar.

[0023] The product characteristics are as follows: Dissolving speed: 5 minutes at 80°C, instantly dissolve at 90°C, without precipitation.

Embodiment 3

[0025] Take 30g of agar powder, 10g of sucrose, add 1kg of water, boil for several minutes until completely dissolved. Stop heating, take it out, freeze and store until it is completely frozen, thaw naturally at room temperature, dehydrate with a plate basket filter press, dry in a dryer at a drying temperature of 50°C, count for 3 hours, cool down to around 30°C, and pre-configure A good 10% lecithin is sprayed onto the surface of the dry object in a spray forest, and timed for 1 hour. Grind and sieve with a 150-mesh pulverizer to obtain instant agar.

[0026] Product characteristics are as follows: Dissolution speed: 2 minutes at 80°C, instant dissolution at 90°C, no precipitation.

Abstract

The invention relates to a preparing method for fast dissolving agar that includes the following steps: dispersing the agar and flux into water under the condition of whisking, boiling for several minutes until fully dissolved; freezing the agar sol until fully frozen, then thawing; dehydrating; drying in natural or by hot air, and spraying the flux on to the surface of dried material; smashing and filtering to gain fast dissolving agar. The invention could be widely used in food, medicine, chemical fields.

Description

technical field [0001] The invention relates to a method in the field of food engineering, in particular to a preparation method of instant agar. technical background [0002] Agar is a natural polymer polysaccharide refined and purified from seaweed such as natural Gemella, Gracilaria, laver, etc. It has been listed as a generally safe product by the US Food and Drug Administration Regulations, and it is approved as a food additive. Pharmacopoeia of Food Chemicals. Agar is a hydrophilic colloid, insoluble in cold water and easily soluble in hot water. Agar has unique importance in industry. Even if the concentration of agar is as low as 1%, it can still form a fairly stable gel (jelly), which is a necessary raw material for food industry, chemical industry, and medical research. [0003] After searching the prior art documents, it is found that Chinese Patent Publication No. 1587284, the publication date is March 2, 2005, and the title of the invention is: a production me...
