• Abstract

  Maillard reactions are responsible for the formation of color and flavor compounds in fried or baked starchy products. The same reactions that make these foods tasty and attractive result in the formation of acrylamide, a potential human carcinogen. The most effective methods to prevent the formation of acrylamide are based on the removal of the precursors, particularly the amino acid L-a…

• Abstract

  Protease producing by micro-organisms has been used for centuries in Japan, Korea and China for the production of fermented foods, involving the hydrolysis of soy protein, wheat and other cereals. The fungus Aspergillus oryzae is a major producer of enzymes such as protease, amylase and ²-glucosidases and is considered safe for use in foods. The use of biotechnological processes such as s…

• Abstract

  Obesity is a chronic disease that affects millions of people in different age groups and socioeconomic groups worldwide. Since the cause is related to multiple factors among then imbalance between physical activity and food intake, endocrine and genetic factors, metabolic disorders, and may be associated or not. The disease is characterized by excessive accumulation of fat in various anat…

• Abstract

  The plant biomasses are composed mainly of cellulose, hemicellulose and lignin. Cellulose and hemicellulose can be hydrolyzed to monomeric sugars (primarily xylose/C5 and glucose/C6) using cellulases and hemicellulases. These molecules are sources of raw material for important industrial products as xylitol and ethanol. However, the tasks of a process for enzymatic hydrolysis of biomass s…
