چکیده
Pepsin merupakan enzim proteolitik yang aktif dalam kondisi asam. Selama ini pepsin dihasilkan dari lambung babi dan sapi. Bahan baku alternatif penghasil adalah ikan tuna sirip kuning. Enzim bentuk kering (powder) akan lebih mudah penyimpanan bersifat stabil. Tujuan penelitian menganalisis karakteristik kuning pengaruh metode pengeringan terhadap tersebut. pepsinpepsin.

Quality assessment of filtered smoked yellowfin tuna (Thunnus albacares) steaks.
UNLABELLED Filtered smoke (FS) has been used to preserve taste, texture, and/or color in tuna and other fish species. This treatment is particularly important in color preservation during frozen storage. The objective of this study was to compare changes in the quality profiles of FS-treated and untreated (UT) yellowfin tuna (Thunnus albacares) steaks stored in 3 ways: room temperature (21 to 2...
متن کاملDeep diving behavior observed in yellowfin tuna (Thunnus albacares)
Yellowfin tuna (Thunnus albacares) are known to preferentially occupy the surface mixed layer above the thermocline and it has been suggested that they are physiologically restricted to water temperatures no more than 8 ◦C colder than surface waters. However, we here report for dive data acquired from a large yellowfin tuna which demonstrate for the first time that this species is indeed capabl...
متن کاملMethodological assessment of 2b-RAD genotyping technique for population structure inferences in yellowfin tuna (Thunnus albacares).
Global population genetic structure of yellowfin tuna (Thunnus albacares) is still poorly understood despite its relevance for the tuna fishery industry. Low levels of genetic differentiation among oceans speak in favour of the existence of a single panmictic population worldwide of this highly migratory fish. However, recent studies indicated genetic structuring at a much smaller geographic sc...
متن کاملEnvironmental preferences of yellow ® n tuna ( Thunnus albacares ) at the northern extent of its range
We used acoustic telemetry to examine the small-scale movement patterns of yellow®n tuna (Thunnus albacares) in the California Bight at the northern extent of their range. Oceanographic pro®les of temperature, oxygen, currents and ̄uorometry were used to determine the relationship between movements and environmental features. Three yellow®n tuna (8 to 16 kg) were tracked for 2 to 3 d. All three...

Recent developments in the field of genomics have provided new and powerful insights into population structure and dynamics that are essential for the conservation of biological diversity. As a commercially highly valuable species, the yellowfin tuna (Thunnus albacares) is intensely exploited throughout its distribution in tropical oceans around the world, and is currently classified as near th...
