Abstract

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.

Abstract

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.

Abstract

Indonesia is a country with a high consumption of coffee, which is in direct comparison with the increased production of coffee waste. Arabica coffee husk (cascara) is coffee industry waste that has not been utilized optimally, which is only 0.76% of the existing potential. Cascara is known to have a secondary metabolite compound that can be utilized as a good product for human health. The effects of Arabica cascara fermentation time on the antioxidant and antibacterial activity of cascara beverage were studied in this study. This research is using a completely randomized non-factorial design. Cascara was obtained from Puntang Mountain, West Java, and was fermented with Lactiplantibacillus plantarum (previously known as Lactobacillus plantarum) for 10, 14, and 18 days. pH value was measured with a pH meter, total sugar content with phenol sulfuric acid method, caffeine content with high performance liquid chromatography (HPLC) method, total lactic acid bacteria (LAB) with drop plate method, total flavonoid and phenolic content with UV-Vis spectrophotometry method, antioxidant activity with 2,2-diphenyl-1-picrylhydrazyl (DPPH) method, and antibacterial activity against Helicobacter pylori with disc diffusion method. Data were analyzed using One-Way ANOVA and DMRT test at the significance level of 0.05. The results showed that prolonged fermentation times reduce the quality of Arabica cascara beverage. The optimal fermentation times were found to be 10 days producing the best balance of pH (3.66), total sugar content (1.29%), caffeine content (0.043%), total LAB (1 x 107), total phenols (12.74 ppm), total flavonoids (3.40 ppm) and highest antioxidant IC50 activity (215 ppm) while for antibacterial activity has not been able to inhibit the growth of Helicobacter pylori.

Abstract

Soymilk is a widely popular beverage and often regarded as a dairy alternative. One option to increase the shelf life of soymilk is by converting it into soy milk powder. Foam mat drying technique offers faster drying process due to larger surface area and better rehydration due to more porous agglomerates. This research aims to determine the effects of egg white addition as a foaming agent in the foam-mat drying process of powdered soymilk on the water content, protein, solubility and hedonic quality. The research employed a completely randomized design with 4 treatments and 5 replications, i.e., addition of egg white as a foaming agent at different concentrations: 25%, 30%, 35%, and 40% (w/v). The results showed that the increasing egg white concentration significantly increases protein content and reduces both solubility and hedonic quality of the powdered soymilk product. However, egg white addition has no significant effect on water content. The best powdered soymilk product was observed at 25% egg white addition, which gave a water content of 3.88%, protein content of 23.61%, and solubility of 61.06%.

Abstract

Probiotics are beneficial bacteria found in probiotic products that can maintain the balance of microflora in the gut. Peanut chocolate jam has the potential to be developed into a probiotic food product. However, the shelf life of this product has not been determined so it is necessary to determine the shelf life using the Accelerated Shelf Life Testing method. This method uses the Arrhenius approach. Determination of shelf life through the calculation of total lactic acid bacteria, aw value, pH value, and total acid during storage. The storage of probiotic peanut chocolate jam used three temperature treatments: 4 ℃, 30 ℃, and 37 ℃. Observations of samples stored at 4 ℃ were made every 5 days until day 25, while samples at 30 ℃ and 37 ℃ were made every 3 days until day 15. The data were analyzed using Microsoft Excel 2016 through the presentation of data in the form of a scatter diagram accompanied by a trendline and then described descriptively. The shelf life of probiotic peanut chocolate jam based on best before stored at 4 ℃, 30 ℃, and 37 ℃ were 49.52 days; 10.98 days; and 7.64 days, respectively. The jam can still be consumed up to 255.29 days; 86.73; and 66.89 days but no longer has the benefits of the probiotics.
