Abstract

The research aims to analyze the chemical and organoleptic properties of sorghum flour fermented by the addition of lactic acid bacteria. The study consisted of three stages, namely the preparation phase for the bacterial starter, the stage of making fermented sorghum flour and the analysis stage. The study consisted of four treatments namely one treatment of sorghum flour which was fermented spontaneously as a control and the other three sorghum flour fermented by the addition of Lactobacillus plantarum lactic acid bacteria, Lactobacillus fermentum and Lactobacillus paracasei. The fermentation process was carried out for 5 days, then the data were analyzed using one-way analysis of variants (ANOVA) at the 95% level with Duncan's further test. The results showed that the addition of lactic acid bacteria had no effect on water content, crude fiber content, tannin content, acidity (pH) value, panelist preference level on color, aroma and texture but had a significant effect on the level of panelist preference on overall sorghum flour resulting from.

Abstract

Deep fat frying is a popular frying method in the world. There are several chemical reactions that occur during the frying process, namely oxidation, hydrolysis and polymerization. These reactions will influence to the physicochemical properties of the oil, such as increasing-decreasing in the peroxide value, an increasing in free fatty acids, a decreasing in the iodine value, an increasing in viscosity and a decrease in the smoke point. The types of oil will affect to the stability of physicochemical properties. Oils rich in unsaturated fatty acids tend to have low heating stability. The type of fried food will also affect the stability of the oil used. Animal-based food (chicken, chicken nuggets and cod) tend to cause oil deterioration more quickly than plant-based foods (potato and banana).

Abstract

The aim of this research is to find out the physical, chemical and organoleptic characteristics of cookies substituted by fermented sorghum flour and to determine the characteristics of the best cookies so that they can be used as alternative products based on local cereals. The study consisted of two stages, namely the manufacture of cookies and analysis. This study uses a completely randomized design with a combination of 50:50 flour and sorghum fermented flour and 100% wheat flour as a control. Data were analyzed using one-way analysis of variants (ANOVA) at 95% level and Duncan's continued test. The results showed that the used of fermentated sorghum flour as a substitute for flour making cookies had a significant effect on color, texture (level of hardness), moisture content and the level of panelist preference on cookie texture, but had no significant effect on protein content and the level of panelist freference on color, aroma, taste, aftertaste and overall of cookies produced.

Abstract

Nori is one of the products that are in demand by the people of Indonesia. Nori is mostly a product that is imported and produced by foreign companies. The price of seaweed, the raw material for making nori, is relatively expensive, so it is necessary to diversify the raw materials for making nori. This study aimed to determine the effect of thickener concentration on the organoleptic properties, chemical properties and physical properties of nori analog from binahong leaves. Organoleptic tests yielded the two best formulas, namely F3 (80% binahong leaves and 20% sago) and F6 (85% binahong leaves and 15% sago). Furthermore, chemical and physical analysis was carried out. The results of chemical analysis on the nori analog showed that analog nori F3 and F6 had a moisture content of 5.72% and 6.84%, an ash content of 4.27% and 5.21%, protein content of 3.66% and 4.60 %, fat content of 9.06% and 8.90% and carbohydrate content values of 77.29% and 74.45%. Physical analysis of analog nori included analysis of texture, color, and thickness. The hardness value of nori on F3 was 2.13 gf, while on F6 it was 2.15 gf. Color of nori analog of F3 and F6 obtained 50.44 and 49.38, with a lighter green color for F3 compared to F6, which produced a darker green color. The thickness values of the F3 and F6 analog nori obtained were 0.92 mm and 0.64 mm.
