Abstract

Rembiga satay is an indigenous processed beef product from West Nusa Tenggara. It undergoes marination with distinctive spices before grilling, contributing to its unique flavor profile. The product's specialty lies in its sensory attributes, distinctly reflecting the characteristic traits of the Lombok region, making it irreplaceable by comparable products from other regions. This study's objective was to thoroughly examine the sensory profile attributes of Rembiga satay using Quantitative Descriptive Analysis. Two methods, namely Rate All That Apply and Flash Profile, were employed for this evaluation. The research involved the engagement of 100 consumer panelists assigned to evaluate the sensory characteristics of four different Rembiga satay products, considering aspects such as taste, aroma, flavor, and texture. Results from the Flash Profile and Rate All That Apply methods consistently indicated that panelists discerned analogous sensory attributes in Rembiga satay. Specifically, Rembiga satay Ririn showed a sensory profile characterized by grilled meat flavor, Rembiga satay Lomboku featured grilled meat flavor, grilled meat aroma, and smoky aroma, and Rembiga satay Napisah presented attributes such as fibrous texture, sweetness, juiciness, spicy aroma, and meat flavor. Meanwhile, Rembiga satay Sinasih exhibited a sensory profile inclusive of umami, chili spiciness, black pepper spiciness, smoky flavor, grilled meat aroma, and chewiness

Abstract

Cascara is a beverage derived from dried coffee cherry pulp, known to have good functional value but with a short shelf life. Fermentation is a technique that can enhance cascara beverages' shelf life and quality and their functional value due to the presence of probiotics and increased antioxidant compounds. The study aimed to optimize the fermentation conditions of cascara tea with water kefir seeds to improve the microbiota content of Lactobacillus sp, Bifidobacterium sp, and Saccharomyces cerevisiae and the antioxidant activity of the beverage. The method in this study used Response Surface Methodology (RSM) with a design selection of Central Composite Design (CCD), using two independent variables, namely fermentation time (X1) and Grain Concentration (X2), with a response of antioxidant activity (%). The findings indicated that a fermentation period of 48 hours and a grain concentration of 8.58% resulted in a probiotic drink exhibiting the maximum antioxidant activity of 65.53%. This optimum treatment resulted in a drink with IC50 antioxidant activity of 173.66 ppm, total phenol 477.24 mg GAE/mL, brightness value (L*) 30.69, redness (a*) 14.06, yellowness (b*) 29.57, pH 3.57, TPT 8.80 (ᵒBrix), viscosity 1.62 mPa.s, total LAB 8.54 log CFU/ml, and total yeast & mold 10.93  log CFU/ml.
