Potensi Ekstrak Biji Pangi (Pangium edule Reinw) sebagai Pengawet Alami Pada Ikan Mujair (Oreochromis mossambicus)

Abstract

Mujair fish (Oreochromis mossambicus) is a freshwater fish that is commonly consumed. This is due that they are easily found and obtrained and with a price in fresh markets that are relatively cheap. Unfortunately, this fish happens to be a very perishable commodity, due to it’s sensitiveness to spoilage because of its high protein content and moisture content. Pangi seeds (Pangium edule) is known to contain tanines, natural polyphenols that inhibits microorganisms through their cell wall permeability. The purpose of this research was to test the potential of pangi seeds crude extract as natural pangi seed toxiti preservatives on mujair fish, shelf life potential on mujair fish. This was achieved by marinating the fish in crude pangi seed extracts at concentrations of 0% (control), 5% and 10% and then store for 4 days at room temperature. Parameters tested on this research includes cyanide identification BSLT toxicity testing and fish spoilage (degradation) through protein changes and pH. Results of this research indicated that pangi seeds crude extract does not contain any cyanide of whatsoever, pangi seed crude extract toxicity testing indicated thatit was not toxic to a concentration of 128233mg/L, meanwhile protein analysis indicated that the optimum concentration of pangi seed crude extract to inhibit fish spoilage is 10% while in terms of pH degradation, the optimum concentration was 5%.

Antifungal Activity and Major Bioactive Compounds of Water Extract of Pangium edule Seed against Aspergillus flavus

“…The toxicity test of the seed water extracts against A. salina larvae has not been reported before, though Sudjana et al [ 46 ] and Simanjuntak et al [ 47 ] have described the toxicity of P. edule seed extract with other solvents. The methanolic and chloroform extracts of P. edule seed had LC 50 of 274.26 μ g/mL and 916.13 μ g/mL, respectively, while the n-hexane extract was nontoxic since it had LC 50 > 1000 μ g/mL [ 46 ].…”

Furthermore, the ethanolic extract of fresh P. edule seed was also considered as nontoxic against A. salina larvae (LC 50 > 1000 μ g/mL) as reported by Simanjuntak et al [ 47 ]. The differences in the LC 50 value can be due to different type of P. edule used which cause differences in the secondary metabolites produced.…”

Meningkatkan Keterampilan Bhakta Veda Poshana Ashram dalam Pembuatan Tum Vegetarian

“…Setelah matang dan diolah, biji keluak dimanfaatkan sebagai bumbu masakan dan memberikan warna hitam pada makanan (Hargreaves et al, 2020;Kirana et al, 2017). Penambahan keluak dalam masakan menghasilkan aroma dan cita rasa yang khas, membuat warna masakan menjadi coklat kehitaman, cocok untuk tum vegetarian, dan juga untuk mengawetkan makanan (Simanjuntak et al, 2020). Masakan dengan keluak memiliki rasa gurih yang khas.…”
