Application of Herbal Secondary Metabolite For Fish Preservation Under Laboratory Conditions

Ahirrao S. D.

Abstract :

The Punica granatum (Pomegranate) peel extract were studied as a natural preservative for extending the shelf life of fresh water fish Mastacembelus armatus for its proximate composition at the per storage and post storage conditions under the laboratory conditions using the distilled water as a solvent for extraction. The preliminary screening of peel extract is showing the presence of some important secondary metabolites such as Alkaloids, tannin, Phenolic compounds, saponins; steroid, Flavonoids, Free amino acids, and vitamin C. Among these number of secondary metabolite were found in the sample of Punica granatum peel, these preliminary phytochemical screening confirming the presence of bioactive potential of that particular plant. Similarly the proximate composition of control sets and experimental sets were also carried showing the measurable changes due to herbal preservation. In the experimental group of fishes the maximum stability of important nutritive compounds were found than the control sets. The crude protein was observed in the range of 17.30-18.80 %, Carbohydrate was recorded in the range of 2.73-2.93% while lipids were estimated in the range of 2.16- 2.26% during the storage period. The above estimated values were found more stable and higher than the control group of fishes. The protein eakdown and lipid oxidation of extract treated fishes were found significantly suppressed during the storage period. The moisture content was also estimated in both the sets of fishes. The moisture content was recorded in the range of 78.66-78.80% .During the storage period ph of both the samples were also recorded and the ph of control group of fishes found in the rapid increasing manner than the experimental group of fishes. Increasing ph of the samples may be due to microbial activity and basic nitrogenous and ammonia compounds. The overall acceptability of both the group of fishes ware also determined by Hedonic scale method and the Quality index method (QIM) by recording the physical, chemical and biological parameters. The overall acceptability score of treated fishes were found much higher than the control fishes therefore the extract of Punica garantum peel may have the preservative potential in its content for extension of shelf life of fishes. All the results of experiments were statistically analyzed and found significant at <0.001 level of significance.
