Abstract

The aim of research was to determine the effect of egg white concentration on physicochemical and sensory properties of nutmeg fruit juice. Randomized Block Design was used in this research with factor namely egg white concentration that consisted of six levels (0%, 1%, 2%, 3%, 4%, 5%). Each level was replicated four times. Parameter tested were pH, titratable acidity, precipitate percentage and sensory (preference of appearance, colour, and taste). Data were be analyzed with Analysis of Variance (ANAVA) (α= 5%). If ANAVA showed a significant effect, it was followed by Duncan’s Multiple Range Test (α= 5%). The results showed that egg white concentration significantly affected on pH, titratable acidity and precipitate percentage. The higher egg white concentration, pH value and the percentage of precipitation increased, but titratable acidity decreased. pH value ranged from 3.20- 3.32, titratable acidity value ranged from 71 mL NaOH 0.1N/ 100 mL – 80.92 mL NaOH 0,1N/ 100 mL, the percentage of precipitation ranged from 2.09% - 14.73%. Egg white concentration also significantly affected on the appearance that ranged from 4.71-5.87 (rather do not like – rather like) and taste preferences ranged from 5.09-5.79 (neutral – rather like), but did not significantly affect colour preferences thar ranged from 5.02- 5.33 (neutral – rather like).

Abstract

Yoghurt is a fermented milk product with activity of Lactic Acid Bacteria (LAB), Streptococcus thermophilus (ST) and Lactobacillus bulgaricus (LB). Red beet juice has attractive purplish red color which is a betalain pigment so it can be an alternative natural dyes for yoghurt products. The purpose of this research is to determine the effect of variation proportion of red beet juice and UHT milk on the physicochemical, microbiological and sensory properties of yoghurt. The experimental design used Randomized Block Design (RBD) with one factor namely proportion of red beet juice and UHT milk which consists of 6 treatments is 0%: 100%, 2%: 98%, 4%: 96%, 6%: 94%, 8%: 92% and 10%: 90% with four replications for each treatment. The parameters observed are acidity, pH, syneresis, total LAB and sensory (preferences of color, aroma and taste). The results of this study showed that the variation proportion of red beet juice and UHT milk affected the physicochemical, microbiological and sensory properties of yoghurt. Increased proportion of red beet juice reduced pH of yoghurt meanwhile acidity, syneresis and total lactic acid bacteria in yoghurt produced increased. The results of weighting test showed that best treatment of red beet yoghurt is 6% red beet juice and 94% UHT milk with a pH value of 4,53, total acid 1,18%, syneresis 0,08%, total LAB 10,5212 log cfu/mL, preference consumer for color 7,29 (like), aroma 7,80 (like) and flavor 7,99 (like).

Abstract

Soymilk has beany flavor and lack of calcium content which can be improved by fermentation of soymilk becoming set soygurt and calcium fortification using calcium carbonate or tricalcium phosphate. The differences of calcium salts may affect the soymilk colloid system, therefore it needs a stabilizer, for example agar. Then, a study of the use of calcium salts and appropriate agar concentration to produce a high calcium set soygurt is needed. The experimental was Randomized Block Design using factor Agar Concentrations on (A): 0,0% (0); 0,1% (1) and 0,2% (2) nested to the of Calcium Salts: Calcium Carbonate (C) and Tricalcium Phosphate (F). Parameters observed were syneresis, calcium content, and sensory characterisitics (preferences to texture and taste of the soygurt). The complement analysis were pH, acidity and protein content of soygurt. The data were analyzed using ANOVA at α = 5%, continued by DMRT test to determine the level of treatment that gives the significant effects. The result show significant difference of agar concentrations nested to the calcium salts gave significant effects to texture & taste of soygurt, but no siginificant effect to calcium content and syneresis of soygurt. Soygurt with 0,0% concentration of agar gave the highest score of texture preference at both kind of calcium salts. Agar concentration at 0,1% and 0,2% gave no significant difference on texture. Kind of calcium salts gave significant effect on taste preference on which soygurt with Tricalcium Phosphate gave higher score than Calcium Carbonate. The preference of taste of soyghurt treated with Tricalcium Phosphate was higher than The Calcium Carbonate, showed by score 4.3-4.4 compared to 3.2-3.8, on scale 1-7.

Abstract

The increasing of health awareness in the society motivated them to consume food that gives values in health, such as organic rice (Oryza sativa L.). Nowadays, red rice became very popular because of their healthy benefit as source of antioxidant. Red rice Saodah variety is the most developed colored rice in Sleman, Yogyakarta. The shelf life of colored rice is around six months. During storage the bioactive compounds and antioxidant activities of the red rice will be changed. One way to inhibit that changes is by using polypropilen (PP) as packaging. The results showed that storage time increased the yield, bioactive content, and antioxidant activity of red rice, but decreased the total anthocyanin. The highest yield of the red rice is in the 4th month (11.86±0.04%) but after that will be decreased. The highest total phenolic (21.49±1.21 mg GAE/g) and total flavonoid (4.38±0.29 mg CE/g) is in the 5th month and decreased in the 6th month. The highest iron reducing power (39.53±6.05 mg GAE/g) is in the 4th month and decreased in the 5th and 6th month, and free radical scavenging activity increased until the 3rd month (1.81±0.16 mg GAE/g) and after that will be decreased.
