| الوصف: | The production and use of protein hydrolysates, derived from animal and vegetable sources in specific formulations is an area of growing interest. Protein hydrolysates can be obtained mainly by three methods: alkaline hydrolysis, enzymatic hydrolysis and acid hydrolysis. However, enzymatic hydrolysis shows to be more beneficial, and with this purpose various enzymes from different sources are used in order to obtain protein rich hydrolysates. Three proteolytic enzymes called Papaína®, Flavourzyme® and Protamex® were used for hydrolysis of mechanically separated meat MSM and manually deboned chicken carcass MDC. The hydrolysis occurred in a thermostatic bath with controlled temperature, time and pH, specific to each of the three enzymes used. Proximal composition of raw materials and lyophilized hydrolysates obtained was performed. Also were performed control analysis of hydrolysis such as degree of hydrolysis, protein, total solids, ash and characterization of amino acid hydrolysates. The results were evaluated by analysis of variance and Tukey test. Protein hydrolysates obtained from MSM and MDC had high protein content characterizing them as a promising raw material in the formulation of special diets. The highest degree of hydrolysis with MCS was obtained with Papaína, and the most efficient MDC enzyme in the enzymatic hydrolysis was Papaína, followed by Protamex and Flavourzyme. The hydrolysates obtained from the MCS with Papaína obtained higher protein and soluble solids content and lower ash content when compared to other hydrolysates with Protamex and Flavourzyme. For the raw MDC, the highest levels of proteins were found in the hydrolyzate obtained with Papaína, soluble solids did not vary between Papaína and Protamex, but the enzyme Flavourzyme presented a smaller percentage of soluble solids (p <0.05) than the other two enzymes. The highest concentration of ash from the hydrolysates obtained from MDC with Protamex and Flavourzyme (6.75% to 7.97%) is the result of pH adjustment during hydrolysis. The ... |
