Abstract

The aim of this study was to evaluate the effect of the types of encapsulation materials, that is skimmed milk and Arabic gum on two probiotics Lactic Acid Bacteria (LAB), including L. plantarum DJ2 and L. plantarum DJ3. The methods of this study were separated into two stages that is probiotic resistance testing during the spray drying process and the viability of LAB after spray drying during storage of probiotic powder for one month at 4oC. Changes in the viability of LAB probiotics before and after the drying process using spray drying were determined by the total plate count. The viability of lactic acid bacteria (LAB) was observed every week for one month of storage at 4oC. The results showed that different encapsulation materials had significant different (P ≤ 0.05) on changes in resistance of probiotics powder during spray drying process. The use of Arabic gum could increase the resistance of probiotics during the spray drying process, meanwhile, the use of skimmed milk was better to be able to maintain the viability of dry probiotic powder both on L.plantarum DJ2 and L.plantarum DJ3 during storage. After four weeks of storage, there was mold and yeast in the skimmed milk and Arabic gum materials. In conclusion, both Arabic gum and skim milk could be used for encapsulation where storage of dry probiotic products is recommended during one month at 4 oC.

Abstract

The purpose of this study was to determine the quality of dadih with bamboo in Taiwan, namely Thorny bamboo (Bambusa stenostachya Hackel) with different incubation times. The materials used are bamboo tubes, banana leaves and Alpine goat's milk from the National Pingtung University of Science and Technology (NPUST) Taiwan. Dadih is made by pasteurizing goat's milk at a temperature of 65oC for 30 minutes, allowed to stand until a temperature of 30oC, the milk is poured into a bamboo tube and covered with banana leaves, then fermented in an incubator at 37oC with time variations (0, 24, 30, 36, 42, and 48 hours). The results showed that the difference in incubation time significantly (p<0.05) on pH, total acidity, syneresis, and general characteristics of dadih. The conclusion of this study is 24-hours incubation is the best time to make dadih because the taste is similar to dadih in West Sumatra.

Abstract

Development of traditional food including dadih to be commercial fermented milk was needed to achieve efficiency and effective of products. Dadih with natural starter needs to be changed with starters because starters can be produced commercially. This study aims to evaluate physicochemical characteristic of fermented goat milk that added with different starters Lactic Acid Bacteria (LAB) isolated from dadih. The materials used for this research were starters LAB that isolated from dadih. In this experiment, treatments were used different starters that namely starter 11, starter 21, starter 25, starter 29, and starter 41 then analized about water content, ash content, fat content, syneresis, and viscosity. The experiment was carried out with three replications. The data were analyzed by ANOVA using the basic design of Completely Randomized Design (CRD) and continued by Duncan's Multiple Range Test (DMRT) if there was a significantly different. The results showed that different starters had influence on water content, ash content, fat content, syneresis, and viscosity. It could be concluded that starters 11 and 41 were the best starter that can be applied in fermented goat milk product based on physical quality with lower syneresis and higher viscosity. But based on chemical quality, starter 11 was the best starter with lower water content and higher ash content.
