چکیده

This study authenticated fish feed sources and determined lard adulteration using dataset pre-processing, principal component analysis (PCA), discriminant (DA) partial least square regression (PLSR) on 19 triacylglycerols (TAGs) 16 thermal properties (TPs). At cumulative variability (90.625%) Keiser-Meyer Olkin (KMO) value (0.811), the PCA identified 10 TAGs 3 TPs with strong factor loading. The dioleoyl-1-palmitoyl glycerol (POO), dipalmitoyl-3-oleoyl (PPO) dipalmitoyl-1-linoleoyl (PPL) characterized feeds containing palm oil while dilinoleoyl-1-oleoyl (OLL), dilinoleoyl-1-palmitoyl (PLL), dioleoyl-3-linoleoyl (OOL), initial cooling temperature (ICT), palmitoyl-oleoyl-linoleoyl (POL), palmitoyl-stearoyl-oleoyl (PSO) final heating (FHT) lard-containing feeds. DA had successfully classified selected PPL, POL, PPO, OOL, ICT, PLL, FHT, POO OLL as most influential biomarkers for authentication purpose. Z-test result (p>0.05) indicated that PLSR could determine percentage of in feed. Hence, incorporating multivariate instrumental analyses authenticate sources.

ganisms which are continually present in the water, soil, and air. Most bacteria are beneficial (e.g., they help digest foods and break down ammonia, nitrite, and organic debris in the environment). There are a number of different bacteria that cause disease in cultured freshwater food fish such as catfish, salmon, and trout. In aquaculture, many bacterial diseases of fish can be successfully t...
