Abstract

Ice cream is a popular food product, but innovation using local ingredients remains limited. This study evaluates the effect of winter melon (Benincasa hispida) addition on the physicochemical and organoleptic qualities of ice cream to support product diversification and enhance nutritional value. The research employed a Randomized Block Design (RBD) with variations: 10% and 25% winter melon in diced or puréed forms. Parameters analyzed included melting rate, Overrun, crude fiber content, vitamin C levels, and organoleptic tests (taste and mouthfeel) using a hedonic scale (25 panelists). Results showed that P1 (10% diced winter melon) yielded the best performance with the highest organoleptic scores (taste: 4.08; mouthfeel: 4.29) and the highest total effectiveness (0.720). P2 (25% diced winter melon) recorded the highest vitamin C and crude fiber content but had lower organoleptic acceptance. Formulations P3 and P4 (puréed winter melon) showed balanced results but did not surpass P1. The P1 formulation, combining whipped cream, low-calorie sugar, and 10% diced winter melon, was the best combination, meeting physical, chemical, and organoleptic quality standards. The use of winter melon not only enhances the nutritional value of ice cream but also supports diversification based on local resources.Keywords - Ice Cream, Wax Gourd, Benincasa hispida, Physicochemical Quality, Organoleptic.

Abstract

Java Ijen robusta coffee is one of the potential coffee types to be developed as a low-caffeine product for sensitive consumers. The decaffeination process aims to reduce caffeine levels without eliminating the sensory characteristics of coffee. This study aims to determine the effect of variation in extraction time using the Microwave-Assisted Solvent Extraction (MASE) method on caffeine recovery, chlorogenic acid content, and organoleptic quality of coffee drinks. The extraction process uses water solvent and microwave power of 450 watts with time variations R1 = 4 minutes, R2 = 8 minutes, R3 = 12 minutes, R4 = 16 minutes, and R5 = 20 minutes. Analysis of caffeine content was carried out using a UV-Vis spectrophotometer, while chlorogenic acid content was determined by the titration method. Organoleptic assessment included colour, acidity and aroma attributes by 25 untrained panelists using median scores. The results showed that extraction time significantly affected caffeine recovery and chlorogenic acid content. The highest caffeine recovery of 57.34% and chlorogenic acid content of 19.19% were obtained at an extraction time of 20 minutes. The most preferred colour and acidity were also found in the 20-minute treatment, while the best aroma was at 12 minutes. Increasing extraction time increased colour intensity, acidity, and caffeine and chlorogenic acid concentrations. These results demonstrate the potential of the MASE method as an efficient alternative in decaffeinating robusta coffee while maintaining sensory quality.

Abstract

Avocado juice is one of the most popular preparations in the community, but avocado fruit is seasonal so that when it is not in season it becomes difficult to obtain or even unavailable, so it is necessary to seek alternative juices with flavors similar to avocado juice. One alternative is juice made from a mixture of cassava tape and pakcoy leaves. This study aims to determine how the proportion of cassava tape and pakcoy affects the chemical and organoleptic quality of the resulting product, and to determine the most optimal proportion to produce the best juice product similar to avocado juice. This study used a quantitative experimental laboratory method with a research design using a Completely Randomized Design with four treatments and three repetitions. Chemical test parameters include reducing sugar reduction with luff-schrool test method, crude fiber with gravimetric test method, vitamin C with iodimetry test. The organoleptic test (taste, aroma, and color) using 25 panelists. Data analysis used Duncan test for lab test results and Kruskal Wallis for organoleptic test. The results showed that (1) the proportion of cassava and pakcoy tape had a significant effect on reducing sugar content, fiber content, and vitamin C content. (2) Reducing sugar content, fiber content, and vitamin C content in cassava and pakcoy tape juice were higher than avocado juice. (3) Organoleptic test showed the best value in treatment J3 in the aspects of taste and color, and treatment J0 in the aspect of aroma. (4) The effectiveness test showed that treatment J3 had the highest value which was the best treatment of this study.

Abstract

This study aims to determine the effects of temperature and Aloe vera concentration on the physicochemical and organoleptic properties of mixed mulberry (Morus alba) jam. Jam is a semi-solid fruit and sugar-based product that requires a thickening agent to achieve optimal texture. Aloe vera was selected as a natural thickening alternative due to its polysaccharide content, such as acemannan and glucomannan, which can form gels, replacing expensive and import-dependent commercial pectin. The research employed a quantitative experimental method with a Completely Randomized Design (CRD), involving four treatment combinations of Aloe vera concentration (75 g and 100 g) and cooking temperature (70°C and 85°C). The parameters tested included physicochemical properties such as viscosity, fiber content, and vitamin C levels, along with organoleptic evaluations involving 25 panelists to assess viscosity and taste. Data were analyzed using analysis of variance (ANOVA) and an effectiveness test to identify the best treatment. The results showed that the combination of 100 g Aloe vera concentration and a cooking temperature of 85°C produced the best-quality jam, characterized by optimal viscosity, high fiber content, preserved vitamin C levels, and high panelist preference for viscosity and taste. This conclusion highlights the potential of Aloe vera as a cost-effective and value-added natural thickening agent for the food industry.

Abstract

Kombucha is a health drink that has good benefits for the body, contains polyphenols and is antioxidant so it is said to be a functional drink. Chamomile positively contains flavonoid compounds, polyphenols, and tannins as antioxidants to ward off free radicals. The purpose of this study was to determine the effect of fermentation duration and concentration of chamomile flowers (Matricaria recutita) to produce kombucha drink with the best physicochemical and organoleptic quality. This study used a one-factorial Completely Randomized Design consisting of four treatments of a combination of fermentation duration (5 days and 7 days) and chamomile concentration (0.5% and 1%), each treatment was carried out three times. Parameters analyzed included color (L*a*b*), pH, antioxidant activity and organoleptic (taste, color, and aroma). The results showed that the length of fermentation and chamomile concentration had a significant effect on color (L*a*b*), pH, antioxidant activity and organoleptic parameters (taste and color). On organoleptic parameters (aroma) did not have a significant effect. The best treatment with antioxidant activity value of 67.09% in treatment F2C2 (7 days fermentation time and 1% chamomile concentration). The highest organoleptic quality was in the F1C1 treatment (5 days fermentation and 0,5% chamomile concentration).
