| This study was carried out to study the alcoholic extract of plants Lorestan province (Allium jesdanum), Sheng (Tragopon carcifolus) and Shatrah (Fumaria parviflora) at three concentrations of 250, 500 and 750 mg/L on the chemical and microbial characteristics of the Kutum fillets. The pH, TVB-N (total nitrogen-volatile bases), TBA (thiobarbituric acid), PV (peroxide), TMA (trimethylamine) and total viable count (TVC) on days 0, 3, 6, 9, 12 and 15 were examined. Neophytadiene in Sheng and Shatare and Di-Methyl-Tri Sulfide, in redbin extract main ingredient contained. pH, TVB-N, TBA, PV, TMA and microbial load increased with increasing storage time in all three treatments and at all concentrations of binred, Sheng and Shatare extract. The microbial load in the treatment of 250 mg/L for all three extracts was in the range (3.24-5.07 log cfu/g) and was within the allowable limit until the ninth day, but in the treatment of 750 mg/L for three was within the permissible range (7 log cfu/g) until the fifteenth day (5.29-6.22 log cfu/g). The highest antimicrobial activity was related to binred alcoholic extract, followed by Sheng and Shatreh alcoholic extracts. |
