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

Sorghum contains nutrients and has the potential to become functional food. The purpose of the research is to know sensory, physicochemistry, and it’s potency as functional food of noodle made from wheat flour substituted by sorghum flour from Numbu and Super 2 variety. The comparison of wheat and sorghum flour used in this research are 35:65; 50:50 ; and 65:35. This research used sorghum flour used to make the noodle comes from two different variety, Numbu and Super 2. Anova was used to analyze the difference between groups and DuncanMultiple Range test for within groups. Sensory analysis was done using 40 untrained panelists shows that there was significant difference based on formulation on the color, aroma, flavor, texture, elasticity, and overall parameters, but there was no difference based on sorgum variety. Noodle samples with higher proportion of sorghum has lower score. The highest sensory value was obtained by wet noodle made from 35% soghum fluor from Numbu variety. Wet noodle resulting from wheat flour and sorghum flour have elongation score range from 10.5833–40.0000%. Water content of the noodle samples range from 33.3731–38.4184%, ash content range from 0.4799–0.8670%, protein content range from 6.2080–8.1109%; fat content range from 1.1250–2.5684%; meanwhile carbohydrate contain range from 51.9081–57.1975%. The noodle has potential to be functional food product due to high antioxidant activity (84.32–89.12%) and the dietary fiber content (2.540–4.370%).
