Abstract

The objectives of this research were to study the effect of storage temperature and pineapple extract on physicochemical, organoleptic, and total bacterial colony of curd. This study used factorial completely randomized design with 2 factors, with two replications. The results showed that storage temperature, pineapple extract and interaction affected significantly fat and protein content, total bacterial colonies, and organoleptis. Storage temperature significantly affected pH, while pineapple extract did not affect pH. The highest fat content wat at room temperature storage without the addition of pineapple extract, namely 12.91%, the highest protein content was at room temperature storage with the addition of 10% pineapple extract, namely 4.74%. Storage at cold temperatures with the addition of 2.5% pineapple extract produced the highest total colonies, namely 2.6 x 106 CFU. At room temperature storage, panelists tended to dislike the color, aroma, and texture of the curd. However, at refrigerator temperature storage, panelists preferred the color of the curd and really liked the taste. Panelists tended to like the curd both without pineapple extract and with pineapple extract. The addition of 7.5% pineapple extract and storage at cold temperatures resulted in a protein content of 4.78% and a fat content of 10.67% which met the National Yoghurt Quality Standard.

Abstract

Soyghurt is a fermented soy milk product using Streptococcus thermophilus and Lactobacillus bulgaricus bacteria. Efforts to enrich drinks high in antioxidants are carried out by combining food ingredients that can function as antioxidants such as soybeans and jicama. The combination of these two food ingredients and the assistance of the fermentation process by S. thermophilus and L. bulgaricans was expected to increase antioxidant activity in soyghurt production.This study used a completely randomized design (CRD) with 2 factors, namely: the first factor was the ratio of soybean juice and yam juice (S) which consisted of 4 treatment levels, namely: S0 = 100: 0, S1 = 75: 25, S2 = 50: 50, S3 = 25: 75, S4 0: 100. Meanwhile for the second factor was the duration of fermentation (F) which consisted of 3 levels of treatment, namely: F0 = 6 hours, F1 = 8 hours, F2 = 10 hours. The parameters observed were total solids, total acid, organoleptic value, antioxidant activity, and total lactic acid bacteria in jicama soyghurt on the best samples.The results showed that both treatment factors had a very significant effect (P <0.01) on total solids, total acid, and organoleptic tests of soyghurt. The study showed that the comparison of soybean juice and jicama juice and fermentation duration resulted a high protein content value of 9.18% and was in accordance with the SNI yoghurt protein content, namely minimum of 3.5%. Antioxidant activity of yam bean soyghurt obtained an IC 50 value of 18.110 mg / L and it was a very strong antioxidant. Total lactic acid bacteria on yam soyghurt was 108 CFU / ml and it was high.Based on this research results, it was suggested that soyghurt processing may use a combination with other types of fruits and use natural food coloring to give different flavors and increase the nutritional values of soyghurt.

Abstract

Hard candy is a solid and hard-textured snack, the main ingredients in the manufacture of hard candy are sucrose, water, glucose syrup, while the additives are flavor, coloring and acidifying. The ratio of the amount of sucrose and glucose syrup used in the manufacture of hard candy will determine the texture that is formed. In general, hard candy is only known as a source of calories and does not contain antioxidants. One type of plant that is rarely used is the fruit of Senduduk Bulu (Clidemia hirta L.), this fruit contains high levels of antioxidants that can ward off free radicals in the body. The aims of this research are to investigate the effect of sucrose and glucose syrup ratio and the addition of different concentrations of senduduk bulu extract on physicochemical and organoleptic properties of hard candy. This study used a Factorial Completely Randomized Design consisting of 2 factors, namely the ratio of sucrose and glucose syrup consisting of 3 levels (70%: 30%, 75%: 25% and 80%: 20%) and the concentration of senduduk bulu extract with 4 levels. (0%, 3%, 6%, 9%). The parameters observed were water content, reducing sugar, antioxidant activity, hedonic organoleptics (color, taste, and texture). The results concluded that the ratio of sucrose and glucose syrup had a significant effect on reducing sugars concentration (P< 0.05), and was very significant (P <0.01) on organoleptic (color, taste) but did not affect water content, and organoeptic texture of hard candy . The addition of senduduk bulu extract had a very significant effect (P <0.001) on water content, reducing sugar concentration, and organoleptics (color, taste, texture) on hard candy senduduk bulu. The hard candy formula most preferred by panelists based on the hedonic test was A1B4 treatment (the composition of the ratio of sucrose and glucose syrup 70%: 30% with 9% senduduk bulu extract). The average value of the panelists' preference level for the parameters of color 3.66, taste 3.54, texture 2.82 and the average value of the test results 1.98% water content, 6.26% reduction sugar and has a very strong antioxidant activity with IC50 value of 36.84 ppm. All analysis tests met the quality requirements of SNI3547.1: 2008 hard candy.

Abstract

Lactic acid bacteria involved in the food fermentation process generally take place spontaneously, especially in traditional Indonesian food processing. One of the local foods that is the traditional food of the people of Tapanuli, North Sumatra, is dengke naniura. This food is processed without cooking with fire only by giving utte (orange) jungga juice and spices left for a few hours. This study aims to obtain lactic acid bacteria isolates from dengke naniura. The first step of this research is to make dengke naniura; and followed by the isolation of lactic acid bacteria from dengke naniura using de Man Rogose and Sharpe media in order to obtain isolates of lactic acid bacteria with general characteristics; and characterization was carried out to determine the specific characteristics, of lactic acid bacteria isolates, which included the Gram stain test, motility test, catalase reaction test, shape, and ability to survive at various acids. The isolation results obtained as many as 10 isolates suspected of being lactic acid bacteria, as indicated by the presence of a clear zone around the isolates. The characterization of lactic acid bacteria showed that all isolates were Gram-positive, rod and spherical in shape, non-motile, and could grow at low acidity pH 3.0. The catalase test showed that eight isolates reacted negatively to catalase and two positively to catalase. Of the 10 isolates tested, as many as 8 showed characteristics of lactic acid bacteria.
