Abstract
Skins, scales and bones are the major by-products of the fish-processing industry. These by-products are not regarded as ordinary saleable products and are usually discarded causing a heavy environmental impact. However, marine by-products are a good source of collagen that could be extracted and further enzymatically hydrolyzed to liberate interesting bioactive peptides. Collagen-derived peptides may exhibit interesting antioxidant activity, potent antihypertensive activity, antimicrobial activity against different strains of bacteria, protective effect on cartilage, capacity to stimulate bone formation, and also other interesting activities (e.g., satiety, calciotropic, or opioid). The bioactive properties of collagen-derived peptides, and also their resistance to protein digestion, make them potential ingredients of health promoting foods.
Keywords: Bioactive peptides, by-products, collagen, fish, gelatin, hydrolysates, nutraceuticals.

Ayurvedic medicinal therapeutic approaches for inflammatory and neurodegenerative disorders
Usually, in our elderly population, neurodegenerative disorders occur due to neuron death. Alzheimer?s disease (AD) is an irreversible and progressive neurodegenerative disease. Dementia is the leading cause of AD, which affects about 30 million people worldwide. According to the World Alzheimer report 2018, a new case of dementia develops every ...read more
Recent Advances in Biotransformation of Bioactive Terpenoids using Aspergillus niger
Biotransformation is the reaction catalyzed by biological catalysts of either isolated enzymes or whole cell cultures of microorganisms. This process has been extensively applied in the conversion of bioactive terpenoids with high regio- and stereospecifity. This process has been also applied in the lead discovery and development. Aspergillus niger has ...read more
