Abstract

This study aimed to determine the effect of storage time for fortified goat's milk yogurt white rice bran flour on organoleptic physical characteristics, pH value, amount of coliform and Salmonella sp. contamination. A total of 20 samples were divided into five treatment groups, based on storage time of 0, 1, 2, 3, 4 weeks, and 4 replications. Every week, tests for organoleptic physical characteristics were carried out using 20 semi-trained panelists, measuring pH values using a pH meter, evaluating the amount of coliform contamination using the MPN method, and Salmonella sp. using SSA media, Gram stain, and TSIA media. Data of organoleptic physical characteristics was analyzed using Kruskal-Wallis followed by Mann-Whitney, data on the amount of coliform contamination and pH values were analyzed using OneWay ANOVA followed by Tukey. Qualitative data on contamination of Salmonella sp. descriptively. The results showed that storage time had a significant effect (p<0,05) on organoleptic physical characteristics, appearance, taste and aroma criteria, but had no significant effect (p>0,05) on color criteria. The results on the amount of coliform contamination and the pH value showed a significant difference (p<0,05). Results on contamination of Salmonella sp. no effect on storage time. In conclusion, a maximum shelf life of two weeks can still be recommended for consumption.

Abstract

Lead (Pb) is one of the heavy m metals polluting the environment which is harmful to t the organism. Pb accumulation triggers free radic cals and disrupts the body's metabolism. Pluche indic ca leaf extract is reported contain flavonoids whiich act as antioxidants and can counteract free radiccal attacks. The purpose of this study was to de etermine the role of Pluchea indica leaf extract preve entive therapy in counteracting free radicals due too exposure to Pb in rats (Rattus norvegicus). Wistar mmale rats aged of 8-10 weeks with a body weight of about 200-250 grams. Rats were divided into 5 tr reatment groups, were group A as negative contr rol, group B as positive control induced by lead (Pb)) 10 mg/rat/day, groups C,D,E given with ethano olic extract of Pluche indica leavesof 200 mg/kgBW, , 400 mg/kgBW, and 600 mg/kgBW and lead (Pb b) exposure of 10mg/ rat/day. Kidney, liver and jejunaal histopathology using HE staining was observed microscopically. The results showed that the administtration of Pluche indica leaves extract could preve ent tissue damage to the kidney, liver and jejunum in rats exposured to Pb. Dose of 600 mg/kgBW show wed histopathological improvement in kidney, liver annd jejunum. The greater the dose, the better prev ention of tissue damage as indicated by tissue condition resembling those of control rats. The conclusion of this study, the Pluchea indica leaf extract has the potential to prevent organ damaged exposed to lead.
