Effect of packaging materials on quality of fish protein concentrate extracted from ribbon fish, Lepturacanthus savala (Cuvier, 1829)
Bibliographic record
Abstract
Fish protein concentrate (FPC) is a healthy and highly nutritive product produced hygienically from fishes in which, protein and other nutrients are more concentrated than fresh fishes. In the present study an attempt was made to study the functional properties of FPC derived from ribbon fish, Lepturacanthus savala were investigated in HDPE packaging materials and their shelf-life. The changes in chemical analysis of FPC powder prepared by Canadian process and stored at room temperature were investigated. Moisture content was increased in the range from 10.78 to 12.72 per cent, whereas the ash content was decreased in the range from 1.87 to 1.08 per cent, protein content was decreased in the range from 86.80 to 83.04 per cent and also, the fat content was decreased in the range from 0.55 to 0.40 per cent during the storage period of 180 days. The changes in functional properties of FPC powder prepared by Canadian process stored at room temperature were also investigated. The viscosity was decreased in the range from 114.00 to 100.00cP; solubility was decreased in the range from 88.92 to 83.78 per cemt, emulsification capacity was decreased in the range from 67.66 to 65.08 per cent, emulsification stability was decreased in the range from 58.84 to 56.02 per cent foaming capacity was decreased in the range from 42.50 to 32.64 per cent foaming stability was decreased in the range from 26.50 to 22.56 per cent gelation was decreased in the range from 26.50 to 20.25g. cm and also, the water holding capacity was decreased in the range from 4.27 to 3.86ml/g during the storage period of 180 days. The TPC (Total Plate Count) of the FPC powder showed increasing trend throughout the shelf-life study. The TPC of the FPC powder in storage at ambient temperature was increased from 0.42x10 2 to 1.48x10 3 cfu/g. As per microbiological quality of FPC extracted from ribbon fish, TPC value was within the acceptable limit during storage period of 180 days. The sensory qualities of FPC powder during storage at ambient temperature for 180 days were observed. For the FPC powder gradual reduction in the scores were observed with increase in the storage period. But, during storage period the sensory evaluation score indicated that the FPC extracted from ribbon fish was within the acceptable limit.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
