“…1,2 Several applications of β-galactosidase have been reported in recent years, such as the valorization of cheese whey which reduce the environmental impact, 3 the improvement of ice creams creaminess and the sweetness of dairy products due to the lactose hydrolysis 4 and the producing of lactose-free fresh dairy products in order to satisfy the needs of lactose intolerance people. [5][6][7] However, enzyme stability upon treatment and dosification can be improved. In this context, the encapsulation of β-galactosidase in hydrogels such as alginate represents a promising tool.…”

“…Para Harju et al (2012), quando se utiliza um processo isolado, as vantagens são menores. Em trabalhos que utilizaram somente hidrólise enzimática, devido aos elevados tempos em contato necessários para realização da hidrólise e pela temperatura ótima da atuação da enzima (35-45°C), observou-se crescimento microbiano.…”

“…Outros aspectos negativos em relação à hidrólise enzimática são doçura excessiva e a ocorrência da reação de Maillard, que é facilitada devido à quebra da lactose em açúcares redutores (glicose e galactose), mais reativos que a própria lactose. Segundo Harju et al (2012), realizando processos combinados, evita-se que o produto final fique com diferente aspecto sensorial em comparação ao leite com teor de lactose original, pois, quando é retirada somente a lactose, pelo uso de membranas, por exemplo, perde-se o gosto levemente adocicado do produto.…”

“…There is a number of whey processing technologies using bar membrane methods and biotransformation into carbohydrate and nitrogen-containing derivatives but the processes require special equipment [6][7][8][9]. The most economically expedient is the industrial realization of fermented whey beverage technologies which can be produced on any dairy enterprise equipment and does not require additional investment or energy [10][11][12].…”
