This study was undertaken to analyze the quality of goat milk based cheese particularly its potential high antioxidant content through fortification of goat milk with purple sweet potato extract. A completely randomized design was used to determine the characterization of goat milk based cheese quality through five levels i.e. 0% (A); 2% (B); 4% (C); 6% (D) and 8% w/v (E) of purple sweet potato extract fortification in goat milk. The results showed that the increased level of fortification by purple sweet potato extract in goat milk based cheese significantly increased the pH value of the cheese (P<0.05) where the highest pH was 6.20 at the level of 4%  w/v. Meanwhile, the yield and total of cheese acid were not affected by the fortification. The content of cheese protein significantly decreased (P<0.05) by the increasing level of fortification by purple sweet potato in goat milk. Goat milk-based cheese on the E treatment contained the lowest protein (19.42%). Functional potency of the cheese increased significantly (P<0.05) when the level of fortification was increased. The highest antioxidant content in goat milk based cheese was 114.47 mg/L. GAEAC at 8% w/v level. In conclusion, by increasing fortified goat milk by purple sweet potato extract up to 8% w/v was able to potentially produce cheese containing a high antioxidant.

Goldfish is one of the freshwater cultured fish that is favored by the community both for consumption and as ornamental fish. Sweet potato (Ipomea batatas L.) is a plant that can be used as a prebiotic in fish feed. Sweet potato (I. batatas L.) is an annual plant that grows in the tropics. Sweet potatoes contain lots of carbohydrates, provitamin A, B vitamins, vitamin C, minerals, and a little fat and protein. This research is an experimental study using Completely Randomized Design (CRD) with 4 treatments and 3 replications each, so the number of experimental units is 12 units. P1 : commercial feed (control), P2: purple sweet potato extract 4 ml / 100 g feed, P3: purple sweet potato extract 8 ml / 100 g feed, P4: purple sweet potato extract 12 ml / 100 g feed.

Retnati, Andriani MAM, Fauza G. 2009. The influence of addition of various sweet potatoes (Ipomea batatas) extract to total count of cells and antioxidant activity in yogurt. Biofarmasi 7: 68-76. The aim of this research was to determine the influence of addition of various sweet potatoes extract to the total count of cells and the antioxidant activity in yogurt. Yogurt was made from fresh milk, skim milk, white sweet potato, orange sweet potato, purple sweet potato, and pure culture of Streptococcus thermophilus 0040 and Lactobacillus bulgaricus 0041 in straight MRS agar. Fresh milk, skim milk powder (5%, b/v), and sweet potato extract (10%, v/v) was pasteurized at 90oC for 15 minutes, cooled to the temperature between 40-45oC, inoculated with 2.5% S. thermophilus and L. bulgaricus with a proportion of 1.4:1, and then incubated at a temperature of 40oC for 15 hours. Yogurt without an addition of sweet potato extract was used as control. The parameters measured in this experiment were the total count of cells with TPC (Total Plate Count) method and the antioxidant activity with DPPH (2,2- diphenyl-1-picrylhydrazyl) method. Samples were taken at one hour interval to examine the total count of cells, while the antioxidant activity was collected at three hours interval. The result of each analysis was plotted into graphics which describing the relation of total bacteria and antioxidant activity with fermentation time. ANOVA was employed to analyze the data. If there was a significant difference, it should be followed by Duncan Multiple Range Test (DMRT) at a significance level α=0.05. The result of this research showed that the addition of various sweet potatoes extracts increased the total count of cells and the antioxidant activity in yogurt. The total count of cells showed no significant different for each sample, it meant that the different colors in sweet potato did not influence the total count of cells. However, yogurt with orange and purple sweet potato extract addition had a significant difference on the antioxidant activity with control and yogurt with white sweet potato extract. In conclusion, the difference colors in sweet potato influenced in the antioxidant activity in yogurt significantly. Sweet potato is potential for milk substitute in yogurt production due to oligosaccharide content and antioxidant activity.

Tapai is one of the typical Indonesian fermented products. This research utilized Lactobacillus plantarum 1 RN2-53 and natural dyes made from plants in the production of cassava tapai. The objectives of this research were to improve the quality of probiotic cassava tapai and to obtain the chemical, microbiological and sensory characteristics of the cassava tapai. Natural dyes used were purple sweet potato extract, red dragon fruit extract and narrow-leaf pleomele extract. The results showed that cassava tapai made with the addition of Lactobacillus plantarum 1 RN2-53 and the addition of natural dyes from plants had different chemical and microbiological characteristics. Tapai made with the addition of red dragon fruit extract generally had a lower pH value and a higher total titrated acid compared to tapai made with the addition of purple sweet potato extract and narrow-leaf pleomele extract, but the alcohol content of tapai made with the addition of purple sweet potatoes extract was higher than the others. The number of lactic acid bacteria was around 109 and had met the probiotic food criteria.

The research aimed to determine the sucrose concentration as a cryoprotectant to obtain the chemical properties and the viability of Lactic Acid Bacteria (LAB) and Lactobasillus plantarum in the synbiotic yogurt. It adopted a one–factor Completely Randomized Design (CRD) by including sucrose in concentrations from 0 %, 2.5 %, 5 % to 7.5 %, three replications. The results showed various sucrose concentrations significantly affected the yields of the purple sweet potato extract– supplemented synbiotic yogurt, reduction–sugar level, the total of LAB, and the total of L. plantarum before and after the freeze–drying process, no significant impact on the moisture content and total quantity of LAB. The best treatment of the synbiotic yogurt was induced through the addition of sucrose with a concentration of 5 % as a cryoprotectant. The treatment signified the following characteristics: 14.797 % of yields, 7.51 % of water content, 14.59 % of reduction–sugar level, 1.98 × 109 CFU mL–1 of total LAB before the freeze–drying and 9.28 × 108 CFU mL–1 after the freeze–drying, 8.23 × 108 CFU mL–1 of total L. plantarum before the freeze–drying and 6.81 × 108 CFU mL–1 after the freeze–drying.

The Stability

Because of the high nutritional value of anthocyanin in purple sweet potatoes (TN57), the stability and quality of anthocyanin in purple sweet potatoes during and after the processing were investigated in this study. First of all, the extraction methods with different parameters, such as temperature, time, solid-liquid ratio, pH value, and solvent were employed to get better extraction efficiencies. After that, DPPH (1,1-diphenyl-2-picrylhydrazyl) and ABTS (2,2′-azino-bis (3-ethylbenz thiazoline-6-sulphonic acid) were used to evaluate the anti-oxidation ability of the extracts. Lastly, the thermal degradation kinetics and photodegradation were used to obtain important degradation factors including the content of anthocyanin residue, degradation index (DI), color parameters, reaction rate (k), and chromatic aberration (ΔE). We found that the extraction condition as using 60% ethanol with 1% citric acid under 80 °C for 40 min was optimal for purple sweet potatoes, which obtained antioxidant capacity as 333 μM TE DPPH, 376 μM TE ABTS+, and 593.6 μM TE ferric ion reducing antioxidant power (FRAP). The results indicate that the most important parameter for the stability of anthocyanin in the purple sweet potato extract (PSPAE) was the pH value rather than temperature. In addition, there was no significant difference in chromatic aberration between the light and dark storage conditions under 37 °C. Thus, PSPAE has the potential to be developed as health foods and drinks rich in anthocyanin.
