Effect of active gelatin-starch film containing Syzygium cumini and Origanum vulgare extract on the preservation of lamb burgers.

The objective of the research was to control the oxidative stability of lamb burgers by applying gelatin-starch active film containing java plum (Syzygium cumini) and oregano (Origanum vulgare). The films were prepared from four formulations: without extract addition (FC), with the addition of java plum extract (FJ), with the addition of oregano extract (FO) and with the addition of java plum and oregano extract (FJO). Films were characterized in terms of the physical, barrier, mechanical and antioxidant properties.

Dietary Oil Source and Selenium Supplementation Modulate Fads2 and Elovl5 Transcriptional Levels in Liver and Brain of Meagre (Argyrosomus regius).

The meagre (Argyrosomus regius) is taking on increasing importance in the aquaculture industry. In view of the limited supply of fish oil (FO) as a feed ingredient, the study of the capacity to biosynthesize long-chain polyunsaturated fatty acids (LC-PUFA) from alternative dietary oil sources is important. We analyzed changes in fatty acid (FA) desaturase 2 (fads2) and FA elongase 5 (elovl5) mRNA levels in livers and brains in response to FO replacement with a blend of vegetable oils (VO) and selenium (Se) supplementation.
