Abstract

Drono Village, Klaten Regency, Central Java, has the potential as a tempe-producing center. Unfortunately, the skills possessed by tempeh artisans are still limited, and they can only make tempeh withouth further processing diversification. Community Service Activities (PkM) are aimed at PKK members who are tempeh artisans to gain knowledge and skills regarding several types of processed tempeh, namely tempeh katsu and tempeh brownies. The activity method was carried out by providing modules several weeks before the training, distributing questionnaires regarding tempeh processing before the activity, carrying out tempeh processing practices, and assessing participants' understanding and satisfaction by distributing surveys. The activity ended with tasting the processed tempeh products that were produced together. Based on the questionnaire distributed, the participants agreed that they had gained additional knowledge regarding tempeh processing. This activity was also considered beneficial, and all participants were satisfied with their community service activities. The PKK community considers this activity essential and can be repeated with other tempeh-processing food training. They also want to apply the knowledge gained as processed products that can be sold or for family consumption.

Abstract

The global demand for plant-based dairy alternatives is driven by health, environmental, and food allergy or intolerance concerns.  This movement has promoted plant-based yoghurts, which are nutrient-rich and non-dairy. This study examines the physicochemical and sensory characteristics of yogurts made from peanut milk and soy milk, both with and without the presence of filler, a prebiotic polysaccharide. Peanut milk yogurt exhibited a greater fat content of 11.2% wb, protein levels at 6.2% wb, and increased viscosity when compared to soy yogurt. However, soy yogurt exhibited elevated microbial loads (1.5 × 10¹¹ CFU/mL) and protein content when supplemented with inulin, suggesting improved fermentation activity. Both yogurts displayed pH levels appropriate for consumption (4.1–4.6), with peanut milk yogurt demonstrating a marginally higher acidity compared to soy yogurt. The addition of filler had a notable effect on the sensory profile, enhancing texture, taste, and overall acceptability for both peanut milk yogurt and soy yogurt. It is noteworthy that filler-enriched peanut milk yogurt exhibited diminished microbial loads and decreased viscosity, probably as a result of unutilized carbohydrate content and the presence of inhibitory metabolites from fermentation. Proximate analysis indicated that peanut milk yogurt has the potential to function as an effective plant-based yogurt alternative, exhibiting quality comparable to soy yogurt. Organoleptic testing revealed a clear consumer preference for formulations supplemented with inulin, resulting in ratings ranging from "like slightly" to "like extremely." This thorough examination offers significant perspectives on the possibilities of legume-based yogurts in addressing the increasing consumer interest in healthy, plant-derived dairy substitutes

Abstract

Kimpul (Xanthosoma sagittifolium) tubers containing a lot of starch can be processed into modified starch with better characteristics. Reaction time is one factor determining the characteristics of acetylated modified starch. The purpose of this study was to assess the effect of reaction time on the characteristics of modified starch of kimpul tubers by acetylation using acetic acid. The research used a Simple Randomised Complete Design (CRD) with 3 types of treatment and 3 replications, namely 110 minutes, 115 minutes, and 120 minutes. Data analysis used One Way ANOVA followed by Duncan’s test with 5 % confidence interval. The research began with the extraction of kimpul starch, modification of starch by acetylation, and then testing the degree of substitution, swelling power, solubility, and clarity of the paste. The length of the reaction will increase the degree of substitution (0,2400-0,6460) but tends to decrease the solubility (0,0171-0,0123 %) and clarity of starch paste (0,852-0,915) and produce a stable starch (2,4996-23535 g/g). Acetylated kimpul tuber starch with a reaction time of 110 minutes can be applied as a thickener for liquid food.

Abstract

The trend of low-fat consumption is not only limited to main meals, but also to desserts. Ice cream, which is usually made from milk, is replaced by plant-based ingredients that have low fat content but high protein such as soybean juice and sorghum juice. The purpose of this study was to obtain the best plant-based ice cream formulation with the ratio of soybean juice and sorghum juice and the use of xanthan gum as a stabilizer. The method in this study was a completely randomized design with two treatments, namely three ratios of soybean juice and sorghum juice (30:70; 50:50; 70:30) and two concentrations of xanthan gum (0.3% and 0.5%). Physical quality parameters observed were overrun and melting time, chemical quality parameters were proximate and sensory quality parameter which were taste, aroma, texture and overall acceptance. The three best treatments were then analyzed for functional value in the form of total phenolics, flavonoids and antioxidant activity. Statistical analysis used One Way ANOVA with Duncan's difference test. The results showed that the ratio of soybean juice and sorghum juice and the concentration of xanthan gum had a significant effect on physical, chemical and sensory parameters. Ice cream with a ratio of 30:70 and a concentration of 0.3% xanthan gum produced the highest overrun value of 39.71% but the longest melting time was obtained in the treatment of a ratio of 50: 50 and 0.5% xanthan gum concentration of 1005.98 seconds or 16.77 minutes. Based on functional analysis, the highest total phenolics, flavonoids and antioxidant activity were obtained in the ice cream treatment of soybean juice and sorghum juice 50:50 with the addition of xanthan gum as much as 0.5% as a stabilizer.

Abstract

Duwet adalah buah tropis berwarna ungu kehitaman saat masak, yang menunjukkan kadar antosianin yang tinggi. Antosianin dapat dimanfaatkan sebagai pewarna makanan maupun sebagai antioksidan alami. Antosianin mempunyai banyak potensi untuk kesehatan manusia, namun stabilitasnya rendah. Penelitian ini mendesain serbuk ekstrak duwet menggunakan maltodekstrin sebagai penyalut dan menentukan konsentrasi maltodekstrin yang tepat dalam mempertahankan stabilitas warna antosianin ekstrak. Hasil penelitian menunjukkan bahwa makin tinggi konsentrasi maltodekstrin, warna serbuk yang dihasilkan menjadi pucat (pink muda), serta kadar antosianin total dan aktivitas antioksidannya menurun. Berdasarkan pertimbangan yield dan aktivitas antioksidannya, penelitian ini merekomendasi menggunakan 10% maltodekstrin untuk memproduksi serbuk antosianin buah duwet. Karakteristik serbuk yang dihasilkan adalah mempunyai kadar antosianin 8,70 mg/100 g, aktivitas antioksidan 72,94%, kadar air 3,75%, tidak menggumpal, berwarna pink muda (L*=81,75, a*=14,74, b*=2,81) dan menghasilkan yield 7,27%. Serbuk yang dihasilkan memenuhi syarat sebagai serbuk minuman tradisional menurut SNI 01-4320-1996.
