Title

Effect of High Fructose Syrup (HFS) Addition on Chemical and Organoleptic Properties of Green Coconut Water Kefir Lita Lusiana Surja; Bambang Dwiloka; Heni Rizqiati

This research aims to determine the effect of High Fructose Syrup (HFS) addition to carbon dioxide (CO2) content, ethanol content and organoleptic properties of green coconut water kefir, and to determine the ideal HFS concentration for green coconut water kefir. Complete Randomized Design is used in this research with 5 treatments and 4 replications i.e. T0 (0% v/v HFS), T1 (2.5% v/v HFS), T2 (5% v/v HFS), T3 (7.5% v/v HFS), and T4 (10% v/v HFS). The CO2 content is measured by sodium carbonate (Na2CO3) titration, ethanol content is measured by distillation, while the organoleptic properties that included level of sourness, level of sweetness, soda sensation, sour aroma, and viscosity are done by 25 panelists. The results show that the addition of HFS is statistically gave significant effect to the CO2 content and organoleptic properties (P<0,05). However, the ethanol content, which analyzed using empirical model of quadratic polynomial regression, show that the addition of HFS is incompatible to the ethanol content of green coconut water kefir. The most optimal HFS concentration is 7.5% v/v, resulting CO2 content of 0.096%; ethanol content 1.545%; and desirable organoleptic properties, which are low level of sourness, high level of sweetness, very high soda sensation, low sour aroma, and high viscosity.

Effect of Lesser Yam Flour Addition on Water Content, Texture, Crude Fiber Content, and Reducing Sugar Content of Donut Made from Wheat Flour Indri Iriana Putri; Bambang Dwiloka; Valentinus Priyo Bintoro

This research aimed to determine the addition of lesser yam flour on water content, texture, crude fiber content, and reducing sugar content of donut made from wheat flour. This research was arranged using completely randomized design with 5 treatments and 4 replications consisted of 5 different lesser yam flour concentrations (0–30%) from total flour that had been used. Water content, texture, and crude fiber content were analyzed using Analysis of Variance (ANOVA) at 5% significance level and reducing sugar content was analyzed using regression equation. The result showed the addition of lesser yam flour can reduce water content. However, it can increase texture, crude fiber content, and reducing sugar content. As conclusion, the concentration of lesser yam flour affected the water content, texture, crude fiber, and reducing sugar in donut.

Functional drinks are processed drinks that contain food components that are beneficial for body health and have good sensory evaluation. Functional drinks can be used to prevent degenerative diseases such as diabetes mellitus. Kombucha is a functional drink fermented from tea and sugar using a kombucha starter or Symbiotic Culture of Bacteria and Yeast (SCOBY). Kombucha has functions as an antioxidant, antidiabetic, anticancer and antimicrobial. A variety of leaves that include phenols and bitter leaves with components that are beneficial to the body can be used to make kombucha. Palm sugar can be used as alternative sugar for kombucha fermentation because palm sugar has a low glycemic index of 35. This study aims to determine the effect of using palm sugar concentration on total dissolved solids, viscosity, pH value, total flavonoids, total phenols, and reducing sugar content. The research results show that the use of palm sugar can increase total dissolved solids, viscosity, pH value, total flavonoids, total phenols and reducing sugars. The best treatment is the use of 25% palm sugar with a total soluble solids value of 18.38˚Brix, viscosity of 1.37 cP, pH value of 3.43, total flavonoids of 0.275 mg QE/g sample, total phenols of 0.99 mg GAE/ml, and reducing sugar of 9.24%.

Red Roselle (Hibiscus sabdariffa L.) is a plant known for its high antioxidant content, making it a suitable ingredient for probiotic water kefir beverages. This study aimed to investigate the impact of different sucrose concentrations in roselle water kefir on viscosity, pH, total yeast count, and hedonic quality. The experimental design used was a Completely Randomized Design. The treatments varied based on sucrose concentrations 6%, 9%, 12%, and 15% (w/v). The findings revealed that the addition of 12% sucrose resulted in a viscosity of 1.22 cP, pH of 2.93, total yeast count of 2.15 CFU/ml, and the highest hedonic quality. In conclusion, the addition of 12% sucrose (w/v) proved to be the optimal treatment, yielding a beverage with suitable viscosity, acceptable pH, favorable total yeast count, and an overall hedonic quality embraced by the panelists.

Mutton is a type of meat that is rarely consumed by the public because it has a high saturated fat content. Mutton has good quality and characteristics and can be used as a functional product to improve body health by adding probiotic bacterial cultures. Mutton jerky can be an alternative to functional meat products. Mutton jerky is fermented utilizing a probiotic starter Lactobacillus plantarum for 6 hours (T1), 12 hours (T2), 18 hours (T3), and 24 hours (T4). The fermented mutton jerky is then dried in a cabinet for 8 hours and then examine. Total lactic acid bacteria was examined by dilution, pH value by pH meter, water activity by aw meter, and organoleptic properties by sensory test. The data of total lactic acid bacteria were analyzed descriptively. The data of pH value and water activity is processed with the ANOVA test and the nonparametric test with the Kruskal Wallis method. The result of this research show fermentation time on lowering the pH value and water activity. At the same time, the total lactic acid bacteria experienced a decrease in value which was analyzed descriptively. The conclusion of this research is that the longer the fermentation will cause a decrease in total LAB, pH value, and water activity and affect the panelist's assessment of the organoleptic test. Mutton jerky with the addition of L. plantarum bacterial starter, which was fermented for 18 hours, had the best treatment to produce low pH values and water activity.
