Chondroitin sulfate (CS) is an essential compound in the treatment of bone and joint disease, is derived from nature, in the body of animals such as shark fin, animal bones and joints, cartilage, chicken breast, ... chemical synthesis can not.
the cartilage is chicken breast-products processing industry chicken, chicken breast cartilage contains a high concentration of CS, so CS extraction and recovery from this source to supplement the part of functional foods.
In this study, the optimal conditions for hydrolysis chondroitin sulfate obtained by Alcalase 2.4L enzyme protease that has been optimized by the response surface methodology (RSM) .
The independent variables were investigated pH (x1: 5.5 ÷ 8.0), temperature (x2: 45 ÷ 55) (0C), Alcalase 2.4L enzyme content / substrate (x3: 0.5 ÷ 6.0) (% v / WPRO) and hydrolysis time (x4: 60 ÷ 300) (minutes).
the results of analysis showed that the variables ANOVA affect CS content (%) obtained by hydrolysis chicken breast cartilage.
the optimal value for the hydrolysis of the variables x1, x2, x3, x4 times in the strategy is the pH = 7.0, temperature = 54 (0C), enzyme content / substrate = 4 (% v / WPRO) and time = 212 (minutes).
Meanwhile, CS content obtained according to the model predictions were: 27.78 (%). This result did not differ significantly (p> 0.05) compared with experimental results obtained are content CS: 00:46 ± 27.40 (%).
From hydrolysis obtained, carried out at a temperature of 550C dryer, CS obtained containing meal.
