Abstract

Collagen-supplemented milk products are susceptible to damage due to high-temperature processing Pulsed Electric Field (PEF) pasteurization is carried out with a pretreatment temperature of <65oC to maintain quality. This study aims to determine the total microbe, the level of microbial decline and the intensity of the sensory profile of milk supplemented with collagen by pretreatment in the PEF pasteurization process. This study used a completely randomized design with a factorial pattern of 2 factors and 3 replications, the first factor was the pretreatment temperature (30, 45 and 60oC), and the second factor was the pretreatment time (10, 20, 30 minutes) which was then pasteurized using the PEF method with a voltage of 15 kv/cm for 120 seconds. Furthermore, these 9 treatments were compared with PEF pasteurized milk without pretreatment and Low Temperature Long Time / LTLT pasteurized milk (pasteurized at 65oC for 30 minutes). The results showed that pretreatment with a temperature of 60oC for 20 and 30 minutes resulted in a total microbial count of 3.406±0.19 CFU/mL and 3.395±0.146 log CFU/mL, respectively. The average total microbe of milk supplemented with collagen in the combination of PEF pasteurization with pretreatment is smaller than the pretreatment process alone with a value below the SNI standard so it is safe for consumption. The average microbial decrease was 2.88 log cycles and was not significantly different (P<0.05) with LTLT thermal pasteurization. The results of the sensory profile intensity test showed that the pretreatment with a temperature of 60oC for 10, 20 and 30 minutes had a sensory profile value that was closest to LTLT pasteurization on the attributes of fishy aroma, milk aroma, and milk taste.

Abstract

Vermicelli, a form of food diversification from rice, was investigated in this study using modified rice flour and white corn flour (Zea mays L). The modification of white corn flour, employing the BIMO-CF starter containing various lactic acid bacteria, aimed to increase amylose levels. Sodium Tripolyphosphate (STPP) was added to improve the vermicelli's physical properties, including stickiness, color, hardness, and chewiness. A 2-factor Complete Randomized Design (CRD) with two replicates was utilized. Data were analyzed using ANOVA at a 5% significance level, followed by a DMRT 5% post-hoc test if significant effects were observed. Results demonstrated significant interactions between the proportions of rice flour, modified white corn flour, and STPP on vermicelli’s water content, ash content, protein content, starch content, amylose content, elasticity, and rehydration power. The optimal treatment was a combination of rice flour and modified white corn flour in a 50:50 ratio with 0.3% STPP, resulting in vermicelli with 8.65% water content, 0.72% ash content, 5.60% protein content, 52.5% elasticity, 127.5% rehydration power, and average sensory scores of 4.04 for color, 4.20 for aroma, 3.88 for taste, and 4.16 for texture, indicating favorable consumer acceptance.

Abstract

Because about 95% of polyphenols do not absorb in the small intestine and instead enter the large intestine, they can provide calming or anti-stress benefits. Therefore, we developed Fruit Bar products using phenol-rich food ingredients like green tea, dried moringa, and dried bay leaves. This study aims to determine the effect of adding different infusions and types of tea on the quality of Fruit bars. This study used a Completely Randomized Design (CRD) with two factors: the type of tea (green tea, moringa leaf tea, bay leaf tea) and the amount of infusion added (40%, 50%, 60%), and the results were analyzed using 5% ANOVA. The best result came from adding 60% green tea infusion, which led to a water content of 23.00%, a pH of 3.5, crude fiber of 0.93%, a polyphenol content of 25.83 mg GAE/g, and an antioxidant activity of 78%.Contribution to Sustainable Development Goals (SDGs):SDG 3: Good Health and Well-beingSDG 12: Responsible Consumption and Production

Abstract

Pectin, a natural polysaccharide, is widely utilized in the food industry, particularly as a base material for edible coatings due to its film-forming ability. Pedada fruit (Sonneratia caseolaris), a mangrove species rich in pectin, remains an underutilized resource despite its potential. This study aims to explore the application of pectin extracted from pedada fruit as a component of edible coatings, with the addition of glycerol as a plasticizer to enhance flexibility and reduce brittleness commonly observed in pure pectin films. A completely randomized design (CRD) with a factorial pattern was employed, consisting of two factors: pectin concentration (1%, 2%, and 3%) and glycerol concentration (1%, 2%, and 3%), each replicated three times. The data were analyzed using Analysis of Variance (ANOVA) at a 5% significance level, followed by Duncan's Multiple Range Test (DMRT) for treatments showing significant differences. Results indicated that increasing concentrations of pectin and glycerol significantly affected the water vapor transmission rate, film thickness, and viscosity of the edible coating. The optimal formulation was achieved with 3% pectin and 2% glycerol, yielding a water vapor transmission rate of 4.083 g/m²/day, film thickness of 0.128 mm, and viscosity of 1022.23 mPa·s. These findings highlight the potential of pedada-based pectin as an eco-friendly alternative for sustainable food packaging solutions.

Abstract

Siwalan sap is highly perishable due to its elevated sugar content, which promotes spontaneous fermentation shortly after collection. Converting siwalan sap into a probiotic beverage offers a promising alternative for extending shelf life and diversifying its utilization. This study aimed to see how different fermentation times and amounts of starter affect the physical and taste qualities of probiotic siwalan sap and to find the best combination of these factors. A factorial completely randomized design (CRD) was applied, comprising two factors: starter concentration (3%, 6%, and 9%) and fermentation time (16, 20, and 24 hours), with three replications. Data were analyzed using Analysis of Variance (ANOVA) at a 5% significance level, followed by Duncan’s Multiple Range Test (DMRT) for significant results. Both factors significantly influenced total lactic acid bacteria (LAB), total titratable acidity, pH, reducing sugar content, total soluble solids, and organoleptic attributes (taste, aroma, and color). The best formulation was achieved with a 3% starter concentration and 20 hours of fermentation, yielding an LAB count of 8.751 log CFU/mL, pH of 4.07, a titratable acidity of 0.750%, a reducing sugar of 1.39 mg/100 mL, and total soluble solids of 17.167°Brix. Sensory evaluation indicated moderate acceptance with scores of 3.2 (taste), 3.35 (aroma), and 3.6 (color) on a 5-point hedonic scale.

Abstract

Rambutan (Nephelium lappaceum L.) is a tropical fruit commonly grown in Southeast Asia, particularly Indonesia and Malaysia. High consumption of rambutan generates large amounts of peel waste, which remains underutilized despite its potential. Rambutan peel contains approximately 26% pectin and hemicellulose, making it a potential alternative source of pectin to reduce dependence on imports. This study aimed to utilize rambutan peel as an alternative source of pectin. The research investigated the effect of extraction temperature (70, 80, 90 °C) and extraction time (60, 90, 120 min) on the characteristics of pectin using a conventional acid extraction method with a completely randomized design (CRD). Temperature and time variables shows significant effects (P ≤ 0.05) on yield, moisture content, ash content, equivalent weight, methoxyl content, galacturonic acid content, and degree of esterification. Pectin extraction from rambutan peel at 80 °C for 120 min produced the optimal pectin yield (7.34%), meeting both SNI and IPPA standards.   Abstrak Rambutan (Nephelium lappaceum L.) adalah buah tropis yang banyak tersebar di Asia Tenggara, utamanya Indonesia dan Malaysia. Tingginyakonsumsi rambutan menimbulkan limbah kulit dalam jumlah besar, namun pemanfaatannya masih belum maksimal. Kulit rambutan mengandung 26% pektin dan hemiselulosa, berpotensi sebagai sumber pektin alternatif untuk mengurangi ketergantungan impor. Tujuan penelitian ini untuk memanfaatkan kulit rambutan sebagai sumber pektin alternatif. Penelitian ini mengkaji pengaruh suhu (70, 80, 90 °C) dan waktu ekstraksi (60, 90, 120 menit) terhadap karakteristik pektin menggunakan metode konvensional dengan ekstraksi asam serta rancangan acak lengkap (RAL). Variable suhu dan waktu menunjukkan pengaruh signifikan (P≤0,05) terhadap rendemen, kadar air, kadar abu, berat ekuivalen, kadar metoksil, kadar asam galakturonat, dan derajat esterifikasi. Ekstraksi pektin kulit rambutan pada suhu 80 °C dan selama 120 menit dapat menghasilkan rendemen pektin yang optimal (7,34%) sesuai dengan SNI dan IPPA.
