Lizard fish (Saurida elongata) muscle protein was hydrolyzed using neutral protease to produce protein hydrolysate (LFPH), and the hydrolysis conditions were investigated using response-surface methodology. The optimum conditions for producing peptides with the highest angiotensin-I converting enzyme (ACE)-inhibitory activity were the following: enzyme-to-substrate ratio of 10,000 U/g, temperat...

Abstract Keeping health and nutritional value of the packed foods has a great value in food industries. Among the diverse methods of food processing and packaging, vacuum packaging is one of the best methods for a variety of food products, such as fish. In order to evaluate the effectiveness of such method in preventing of bacterial growth during preservation of fish fillets, four vacuum p...

Lizard fish protein hydrolysates (LFPH) were prepared from Lizard fish (Saurida elongata) proteins possessing powerful angiotensin I converting enzyme (ACE) inhibitory activity and the fraction (LFPH-I) with high ACE inhibitory activity was obtained through ultrafiltration. The active Fraction (F2) was isolated from LFPH-I using immobilized metal affinity chromatography (IMAC-Ni2+). Analysis of...

The reproductive biology of lizard fish Saurida tumbil in the Jizan region of the Red Sea was studied during 1986. Females outnumbered males and attained larger size than males. Among young individuals male s were more numerous than females, while in older age groups the females were more num erous. There is no significant difference in length-weight relation ship between the sexes . The equa t...

The mean total length and age at first maturity were established for Nemipterus japonicus, Leiognathus virgatus, Gerres oyena, Saurida undosquamis, Mulloidichthys flavolineatus Terapon theraps from the Sudanese coast off Suakin. Five stages identified each species. Females dominated in 53.3% of cases, but not significantly (p > 0.05) 40% sex ratio was equal two cases (6.7%). lowest recorded fec...
