Abstract

Red rice crackers are a type of snack made from red rice and tapioca, with additional nutrients derived from substandard carrots. Substandard carrots that can still be utilized include broken carrots, irregular sizes, post-harvest defects, and branched roots, which are processed into flour to facilitate their use. This research aims to determine the effect of the addition of carrot flour on the chemical properties, and acceptability of red rice crackers, and the best treatment based on chemical properties and acceptability. The method used is a Completely Randomized Design (CRD) single factor with treatments using red rice flour compared to carrot flour P1 (90%:10%), P2 (80%:20%), P3 (70%:30%), P4 (60%:40%). Based on the research results, the addition of carrot flour significantly affects the ash content, fat content, protein content, color, aroma, taste, texture, and total acceptance but does not significantly affect the water content and carbohydrate content. The best red rice crackers are obtained from treatment P1 (90% red rice flour: 10% carrot flour) with chemical values of water content 2.06% (db), ash content 3.16% (db), fat content 2.97% (db), protein content 9.65% (db), carbohydrate content 84.22% (db), and acceptability values of color 1.57 (very like), aroma 1.87 (very like), taste 1.53 (very like), texture 1.80 (very like), and total acceptance 1.47 (very like).

Abstract

Synbiotic set yogurt with the addition of mung bean extract has the potential as an alternative functional food that can meet the needs of people who want to have a healthy life. Mung beans are a source of prebiotics because they contain oligosaccharides in the form of raffinose and stakiose. The addition of mung bean extract concentration in the synbiotic set yogurt aims to determine the effect of increasing the concentration of mung bean extract on the microbiological, chemical, and acceptability characteristics of the synbiotic set yogurt and determine the concentration of mung bean extract that produces the best synbiotic set yogurt based on SNI. This study used a completely randomized design (CRD) with four treatments, namely P1 (15% mung beans extract), P2 (20% mung beans extract), P3 (25% mung beans extract) and P4 (30% mung beans extract). Based on the results of the research that has been done, it can be concluded that the addition of mung bean extract to the synbiotic set yogurt has a significant effect on microbiological values (prebiotics, pH, and total lactic acid bacteria), acceptability values (taste, color, texture, and overall attributes) and chemical values (ash and lactic acid content). But not significantly different from the aroma attribute. The best concentration of synbiotic set yogurt with the addition of varying concentrations of mung bean extract is found in treatment P1 (mung bean extract 15%), namely prebiotic levels of 2.6 x 108 CFU/ml, pH 3.83, total Bal 3.2 x 107 CFU/ml, ash content 0.73%, total lactic acid 0.54%, taste 1.84, aroma 2.16, color 1.60, texture 1.72 and overall 1.84

Abstract

Persimmon fruit is a source of nutrients that are beneficial for the body's health and energy. However, because its use is not optimal, this fruit is susceptible to damage and rot, causing prices to fall and lack of market appeal. However, the pectin content in persimmons is not sufficient for making sheet jam, so it is necessary to add pectin. This research aimed to evaluate the effect of different pectin concentrations on the chemical and organoleptic characteristics of persimmon jam, as well as determine the best pectin concentration. This research used a Completely Randomized Design (CRD) method with four single treatments, namely the addition of pectin with a concentration of T0 (0%), the concentration of T0 (0%), T1 (0.5%), T2 (1.0%), T3 (1.5%). The results showed that the addition of different concentrations of pectin significantly influenced the value of vitamin C, water content, antioxidants, total soluble solids, as well as organoleptic attributes of texture and overall persimmon sheet jam. However, there was no significant effect on the organoleptic attributes of taste, aroma and colour. The best pectin concentration for persimmon sheet jam is the T3 treatment (1.5% pectin), which has the following characteristics: water content 36.13%, Vitamin C 3.10 mg/100 grams, antioxidant activity (IC50) 93 .70 ppm, total dissolved solids 66.1˚Brix, and organoleptic assessments for taste, aroma, colour, texture and overall attributes were 2.52, 2.24, 2.60, 2.88 and respectively.
