Abstract

Pasteurized milk stored at cool temperatures generally have a relatively short shelf life. Antibacterialactivity of noni juice in maintaining the quality of pasteurized goat's milk stored at cold temperatures wasinvestigated. Characteristics of pasteurized goat's milk examined were organoleptic performances, microbialgrowth (total plate count and psychotrophic bacteria), chemical characteristics (protein, pH and acid total) withthe addition of noni juice at variation concentrations) (0%, 5%, 7.5%, 10%, and 12.5%) and times of storage(0.5, 10, 15 and 20 storage days). The results showed that the concentration of noni juice addition of 0 % -7.5 %on the parameters of colour, flavour, taste and homogenity and still were acceptable by consumers. Theinhibitory effects of TPC amount of growth were shown in 12.5% (2.8x101-3.3x101cfu/ml), and this inhibitoryeffects weren’t significantly different between each other of concentrations) (α> 0.05). The low decrease ofprotein content was indicated at concentrations of 7.5 % and still with the value of under SNI up to 20 days ofstorage (from 3.48 to 3.19%). The lowest decrease of pH and the increase acid total titration were shown atconcentrations of 5% with the values of pH (6.40 to 6.17) and acid total (0.20 %-0.22%). Based on organoleptic,microbial and chemical characteristics, it can be concluded that the best concentration of noni juice than that theothers can be added to the pasteurized goat milk during storage was 5%.

Abstract

Patin is a type of fish commonly processed into fillets for export purposes. Patin fillets are prone to deterioration during cold storage. Nisin is a natural preservative that inhibits microbial growth, particularly Gram-positive bacteria; however, it remains ineffective against Gram-negative bacteria. A combination of nisin and chitosan has been reported to inhibit Gram-negative bacteria. This study aimed to analyze the effect of combining nisin from Lactococcus lactis subsp. lactis and chitosan, applied by bottle-spraying, on the quality parameters (total plate count/TPC, pH, total volatile base nitrogen/TVB-N, and thiobarbituric acid/TBA) of patin fillets during cold storage (4±1 °C) for 16 days. The treatments consisted of 2% chitosan, combinations of nisin–chitosan (125 IU ml-1 nisin and 1.5% chitosan, 250 IU ml-1 nisin and 1% chitosan, 500 IU ml-1 nisin and 0.5% chitosan), and 1,000 IU ml-1 nisin. The results showed that both the combined treatments of nisin and chitosan, as well as the individual applications of 1,000 IU ml-1 nisin and 2% chitosan, slowed the increase in TVB-N and TBA values. However, these treatments did not significantly affect pH or microbiological quality (TPC). The combination treatment effectively delayed chemical spoilage (TVB-N, TBA) during cold storage; however, microbial limits (TPC) were reached by day 12, indicating that the overall shelf life of patin fillets could not be extended beyond this period.
