High quality, Food ingredient,food texture improver,Curdlan CAS NO.54724-00-4

Characteristic of Curdlan

1,Solubility

Curdlan gum does not dissolve in water, but can dissolve in alkaline solution (PH>12),including sodium hydroxide, trisodium phosphate , calcium phosphate etc., furthermore , it can also easily disperse in cold water and form one more homogeneous dispersion systerm after a high-speed stirring treatment .

2, Fomation

Heated to 80℃ or above , it will form the high gel with thermal irreversibility .The gel strength of curdlan gum increases with the growth of heating temperature. Continuing heating to 130℃ , the gel strength keeps rising and increases with the growth of concentration . The gel strength of low gel is weaker than the one with thermal irreversibility .Once crushed, the high gel can not be restored to its original state. Generally, curdlan gum is used in the form of high gel in the food processing industry.

3, Features of Curdlan Gel

1. Thermal Stability: The curdlan gel has strong thermal stability in heat. It keeps this property in food processing and kitchen cooking, for example, in boiled, fried, microwave and other heating conditions.

2. Freeze-Resistance: The gel structure of curdlan gum does not change in frozen and thawed processing, so it also can be used in frozen foods.

3. Water-Seperation: When directly used in food processing, the curdlan gel will occur the water separation. And water-seperation increases with the climb of temperature, decreases with the density of curdan increase. Moreover, the phenomenon can be inhibited by adding starches (corn starch, chemical starch).

Application in Minced Filet

In minced filet , such as Kato Ni, Fish Steak , Fish Balls ,Crab Bar etc . Main process as below :

1, According to the proportion mix curdlan with ice water, chop with high-speed homogeneously for 5 mins (3600 R/M) with the temperature above 30℃.

2 ,Two directions :

Direction 1:

(1) Keep the chopped curdlan slurry constantly heating to about 60℃, then cooling to room temperature .

(2),Chope the cooled curdlan to miced state, then mix  with the raw meat and other accessories according to the process needs .

(3),Remains the same of the follow-up process.

Direction 2:

(1),Mix the curdlan slurry with the raw meat and other accessories according to the process needs .

(2),Remains the same of the follow-up process.

The Effect of adding Curdlan :

1. Can alternative part of the minced fish, reduce the cost

2. Can make the product surface brighter ,make the products more beautiful

3. Can improve the smooth of the product

4.Can Increase water holding capacity when refrigerated,prevent the occurance of yellowing phenomenon in cryostorage .
