Enzymatic Hydrolysis of Casein: Effect of Degree of Hydrolysis on Antigenicity and Physical Properties

Abstract: Casein was enzymatically hydrolyzed for potential use in a hypoallergenic infant formula. Samples from the digest at different hydrolysis time (HT) intervals were tested for antigenicity, hydrophobicity, net charge (zeta potential), and emulsifying activity. Casein antigenicity loss could be approximated by three-phased first-order kinetics. Extensive antigenicity loss occurred during the first 10% of HT and relatively small changes occurred during the remaining 90% of HT. Hydrophobicity and emulsifying activi… Show more

“…Tables III and IV give the DH for the partially hydrolyzed soybean, sesame, and rice bran meal proteins when proteolytic enzymes papain and bromelain were used, respectively. The values of DH in tables I and II may be useful in preparing hydrolysates with certain functional properties, since the DH is the principle determinant of protein hydrolysate properties (1,2) . From Tables I and II, twelve hydrolysates were chosen for further study.…”

“…This group encompasses a wide range of products with varying degree of hydrolysis. The degree of hydrolysis (DH) is a measure of the extent of hydrolytic degradation of proteins and is the most widely used indicator among different protein hydrolysates (1,2). Partially hydrolyzed proteins are prepared by stopping the hydrolysis process at a desired time.…”

“…De hecho, evitar estos alimentos de manera estricta es la única forma de impedir la reacción contra ellos. Otra posibilidad es tomar dietas constituidas por hidrolizados proteicos hipoalergénicos (Mahmoud et al, 1992, Hindi-Tamelikecht et al, 1997, Pahud et al, 1984, Watanabe 1993, Ovensen 1991b, Siememsma et al, 1993, Clemente et al, 1999b.…”

“…9 As proteínas hidrolisadas vem sendo utilizadas há varias déca-das para administração nutricional em indivíduos que não podem digerir a proteína intacta. 10 Os hidrolisados protéicos são produzidos e aplicados na indústria de alimentos incluindo substitutos lácteos, suplementos protéicos, estabilizadores de bebidas, realçadores de sabor e produtos de confeitaria.…”

“…Existe ampla divulgação cientifica sobre hidrolisados de pescado e outras matérias primas, [8][9][10][11][12][13][14][15][16][17][18] no entanto, é escassa em relação às proteínas de frango. Como o Brasil tornou-se um dos principais produtores de carne de frango, com uma produção anual de aproximadamente 10 milhões de toneladas, o estudo do comportamento de enzimas proteolíticas sobre as proteínas desta matéria prima contribuirá com o conhecimento necessário para promover novas tecnologias aplicadas tanto a cortes nobres como a resíduos da industrialização, com a finalidade de obter novos produtos com diferentes propriedades funcionais e usos na indústria de alimentos.…”
