AI Article Synopsis
- The fish processing industry waste can be transformed into valuable products like fish feed to reduce its negative environmental impact.
- The research aimed to find the best dose of RGL.1.1 enzyme for breaking down protein from catfish waste and to test the effectiveness of the resulting protein hydrolysate in snakehead fish feed.
- Findings indicated that a 6% enzyme concentration increased protein availability and that including up to 45% protein hydrolysate in the feed improved growth performance and feed efficiency in snakehead fish.
Article Abstract
The negative impact of fish processing industry waste needs to be minimized, by processing it into valuable products, one of which is fish feed. The objectives of this research were to determine the optimum dose of crude extract of RGL.1.1 enzyme in hydrolyzing protein from the waste of catfish () fillet processing and to evaluate the effectiveness of using protein hydrolysate in snakehead fish () feed. There were four doses of enzyme treatment for protein hydrolysis designed in a completely randomized design, namely, 0, 4, 6, and 8% (v/w) with three repetitions. Furthermore, to assess the quality of protein hydrolysate, an analysis of soluble protein level, hydrolysis degree, amino acid content, fatty acid content, and digestibility was carried out. The percentage of protein hydrolysate applied in the feed formula was 0, 15, 30, and 45% (v/w), which was designed in a completely randomized design with three replications. Absolute weight growth, specific growth rate, protein efficiency ratio, feed efficiency, and snakehead fish survival were measured to evaluate the effects of the feed formula. Results showed that the crude extract of RGL.1.1 enzymes at a concentration of 6% (v/w) enhanced the availability of soluble proteins, amino acids, fatty acids, and feed digestibility. Protein hydrolysate application in snakehead fish feed formula up to 45% (v/w) can improve the growth performance (8.03%), protein efficiency ratio (25.66%), and feed efficiency (23.41%).

Erectile dysfunction (ED) is a male sexual disorder mainly caused by a reduction in the cellular concentration of cyclic guanosine monophosphate (cGMP), which is degraded by phosphodiesterase type-5 (PDE-5). Oyster protein (OP) and its hydrolysates have been used for centuries to address male erectile dysfunction, however the mechanisms and evidence supporting their efficacy remain unclear. In this study, OP was hydrolyzed using trypsin to produce peptides that inhibit PDE-5.

Background: Consuming collagen hydrolysate (CH) may improve symptoms of exercise-induced muscle damage (EIMD); however, its acute effects have not been compared to dairy protein (DP), the most commonly consumed form of protein supplement. Therefore, this study compared the effects of CH and DP on recovery from EIMD.
Methods: Thirty-three males consumed either CH ( = 11) or DP ( = 11), containing 25 g of protein, or an isoenergetic placebo ( = 11) immediately post-exercise and once daily for three days.
