Comparative Experiments With Other Feed Binding Agent

The Test for the Stability of the Product Soaked in Freshwater
The Materials for Test referred to Form 2
        Form 2   The Kinds and Dosage of the Binder Used in the Test

The Test Approach
   Referring to the test approach adopted by Shanghai Fishery University, We append the different kinds of binders to the standard formula and pellet the feeds drying the feeds an hour in a 80 ℃ oven. Then We put the four different kinds of pelleted feeds appended with the binder and the control feed without the binder into five 250ml beakers fully filled with freshwater respectively for comparison, soak them in the freshwater for 0.5, 1.0, 1.5 2.0 and 4 hours respectively under the conservatory, stir the water gently with a glass rod, clip the feed lightly with a forceps and observe the changes in the appearances of the feeds.

The Result of Test
The Stability of the Pellet Feeds Soaked in Freshwater can be referred to Form3
       Form 3   Stability of the Pellet Feeds Soaked in Freshwater

	0.5 hour	One Hour	1.5 Hours	2 Hours	4 Hours
The Control Feed (Without Binder)	+ + +	+ + + +	+ + + +	+ + + +	+ + + +
CMC—Na	+	+	+ +	+ +	+ + +
Wheat Protein Powder	_	+	+ +	+ +	+ + +
Sodium Alginate	+	+	+ +	+ +	+ + +
JB Feed Binder	_	_	_	+	+

Remark: “_ ” means no change on the appearance after stirring.
“+” means the feed does not break when it is clipped lightly by a forceps.
“+ +” means the feed dilates and can be clipped lightly by a forceps.
“+ + +” means the feed breaks immediately when it is clipped lightly by a forceps.
“+ + + +” means the feed dilates completely and disintegrates after stirring the freshwater.

We can conclude from the above forms that the stability of the feed appended with the binder in the freshwater is better than that of the feed without the binder. Comparing with the JB Feed Binder for pellet feed, the addition level of CMC—Na, Wheat Protein Powder and Sodium Alginate is high and their stability in the freshwater is weak. The feed appended with CMC—Na, Wheat Protein Powder and Sodium Alginate dilate after being soaked in freshwater for one to two hours. While JB Feed Binder for pellet feed is much better than other binders in terms of the addition level and stability in the freshwater. The feed appended with the JB binder softens, but does not dilates when it is soaked in the freshwater and the shape of the feed is stilled well preserved even after four hours in the freshwater. The stability of JB binder for pellet feed is really excellent.

The Test for Pellet Dissipation Rate of the Feed Soaked in Freshwater
        The Materials for Test
    The same as in the Form Two
        The Test Approach
    First, dry the pellet feed already made in Test One in a 100—105 ℃ oven to a constant weight and weighs it. Then, soak the feed in the fresh water with 8 unary sifting screen for two hours under the conservatory and fish out. Finally, dry the feed to a constant weight under the same temperature as the above and weigh it again. The dissipation rate can be calculated through the following formula.

W1 and W0 in the Formula represent absolute dried weight before and after the soaking.

The Result of Test 
The result of test can be referred to Form 4

Form 4 The Test Result of Dissipation Rate of Pellet Feed Soaked in Freshwater

The Names of Binders	The Dissipation Rate Soaked in the Freshwater for two hours.
CMC—Na	26%
Wheat Protein Powder	25%
Sodium Alginate	31%
JB Feed Binder for Pellet feed	4%

We can conclude from the above form that the dissipation rate of the feeds appended with CMC—Na, Wheat Protein Powder or Sodium Alginate and soaked in the fresh water for two hours far exceeds 10%, while the dissipation rate of the feed appended with JB Feed Binder and soaked in the fresh water for two hours is only 4%. So JB Binder is very good in terms of water resistance and is really a good binder for the pellet feed.
