This research was investigated the effect of different kefir grain starter concentration on yield, pH, carbon dioxide (CO2) content, and organoleptic properties of buffalo milk kefir, and to investigated the ideal kefir grain concentration for good quality of kefir. Complete randomized design used in this research with 4 treatments and 5 replications in concentration 2.5, 5, 7.5, and 10% g/v kefir grain. Buffalo milk, kefir grain, Na2CO3 solution, 1% PP solution, pH meter, burette, and analytical balance were used in this research. The yield and pH of kefir was measured. Carbon dioxide (CO2) content was measured by Na2CO3 titration, while the organoleptic properties that included level of sourness, sour aroma, texture, and overall acceptance were done by 25 panelists. The results indicated that different kefir grain starter concentration significantly affected to the yield, pH, CO2 content, and organoleptic properties (p<0.05). The most optimal kefir grain concentration was 5% proved by yield 81.81%, pH value 4.20, CO2 content 0.43%, and proper organoleptic properties which were low level of sourness, acceptable aroma of kefir and texture. As conclusion, the concentration of grain relied on the kefir properties that may achieve in the optimum quality of kefir.

This research was done to detect total yeast on small scale kefir industry in Semarang, Central Java, Indonesia. The total plate count method was used to analyze total yeast in mango flavored kefir. This research used mango flavored kefir since this products was the top demand by consumer among kefir flavored products that was produced in this manufacture. Kefir from manufacture was transferred to laboratory using container box to provide buffer in the temperature decrease. As result, total yeast in mango flavored kefir was 1,21±0,06x105 CFU/ml. This total yeast was in the range of the Standard Codex 243-2003 which required a minimum total of 104 CFU/ml. The 1 log unit differences should provide the awareness to manufacture to maintain kefir in low temperature to minimise the multiplication of total yeast resulting the appearance of unwanted flavor. As conclusion, the mango flavored kefir was analyzed in total yeast successfully and in the range of Standard Codex of kefir

This research aimed to determine the addition of lesser yam flour on water content, texture, crude fiber content, and reducing sugar content of donut made from wheat flour. This research was arranged using completely randomized design with 5 treatments and 4 replications consisted of 5 different lesser yam flour concentrations (0–30%) from total flour that had been used. Water content, texture, and crude fiber content were analyzed using Analysis of Variance (ANOVA) at 5% significance level and reducing sugar content was analyzed using regression equation. The result showed the addition of lesser yam flour can reduce water content. However, it can increase texture, crude fiber content, and reducing sugar content. As conclusion, the concentration of lesser yam flour affected the water content, texture, crude fiber, and reducing sugar in donut.

The study was investigated the functional properties of buffalo skin gelatine. Gelatine was extracted from swamp buffalo skin using crude acid protease from cow’s abomasum (CAPC) in concentration variation 0; 2.5; 5; and 7.5 U/mg. The temperature to hydrolysis included at 28 °C, 37°C and 40°C. The emulsion activity index (EAI), Emulsion stability index (ESI), foaming expansion (FE) and foaming stability (FS) were investigated. The interaction between CAPC concentration and hydrolysis temperature has a significant effect (P <0.05) on the emulsion activity index (EAI), emulsion stability index (ESI), foaming expansion (FE) and foaming stability (FS). The highest EAI was obtained in CAPC concentration of 5 U /mg, hydrolysis temperature of 40°C, which was 12.04 m2/g. The higher concentration of CAPC decreased the ESI. The hydrolysis temperature of 40°C produces higher FE than 28°C and 40°C. The highest FE is obtained at CAPC 5U/mg, 37°C hydrolysis temperature, which is 102.93%. The FS values range from 44.91-55.00%. This value is higher than commercial gelatin (bovine skin gelatin) which is 34.90%. The conclusion of this study is that buffalo skin gelatin with the best functional properties was obtained using CAPC 5 U/mg, the hydrolysis temperature of 40°C.

A study was conducted to review on pathogenic bacteria Listeria monocytogenes, the detection and the sequencing gene methods isolated from meat products, compare selected methods that detect the presence of Listeria monocytogenes in selected raw and processed meat products. Results indicate that Listeria monocytogenenes (originally named Bacterium monocytogenes) is a gram-positive, non-sporeforming, highly mobile, rod-type, and facultative anaerobic bacterium species. It can grow under temperatures between -1.5°C to 45°C and at pH range between 4.4 and 9.4, with the optimum pH of 7. Rapid methods (PCR based and VIDAS-LDUO®) detected Listeria monocytogenes faster than the conventional method. It was also gathered that Phenotypic identification and Genotypic identification are two types of confirmation test for Listeria monocytogenes. Listeria monocytogenenes can be found in raw meat and meat product because of environmental contamination, cross contamination or error process.

This study aims to assess the probiotic properties of Lactic Acid Bacteria isolated from the traditional sourdoughs used for bread making in Turkey against some gut conditions. A total number of 29 samples from twelve provinces of Turkey were collected, and screened for the presence of lactic acid bacteria using microbiological methods. The microbiological screening yielded 148 presumptive isolates. Of them, 62.8% were characterized as lactic acid strains by VITEK® MS. Following that, the characterized isolates were subjected to probiotic property testing, including gastric acid resistance, bile resistance and hydrophobic ability. The results showed that 44.1% exceeded gastric pH resistance, 33.3% survived under gastrointestinal system bile salt conditions, and 10.8% exhibited high hydrophobicity ability. In conclusion, our study revealed that only 4.3% (1 Enterococcus faecium, 1 Lactobacillus brevis, 1 Lactobacillus pentosus, and 1 Lactobacillus plantarum) out of 93 lactic acid bacteria isolated from the traditional sourdoughs could meet all probiotic requirements against some gut conditions.

Dadih is a traditional fermented food of West Sumatra, Indonesia that is considered being able to provide health benefits. Fermentation starter used a combination of L. casei and L. plantarum used proper fermentation length is expected to generate optimal antioxidant activity which increases the functional properties of the dadih, it can be classified as a functional food. The purpose of the research was to find out the total lactic acid, pH values, soluble protein, and antioxidant activity using different length of fermentation with a combination starter L. casei and L. plantarum. Complete Random Design with 5 treatments and 4 replicates was used as the experimental design. The treatments given consists of T0 = incubation of dadih for 48 hours, T1 = incubation for 60 hours, T2 = incubation for 72 hours, T3 = incubation during the 84 hours, T4 = incubation for 96 hours. The results showed that long fermentation resulted in the significant changes on the total lactic acid bacteria (LAB), pH values, protein soluble, and antioxidant activity (P<0.05). As conclusion, different length of fermentation increased lactic acid bacteria and total antioxidant activity in dadih. Optimum fermentation in 72 hours length of time, this corresponds in order to produce dadih with antioxidant activity and optimal total lactic acid, pH values and protein soluble.

This study was done to preserve snake fruit cultivar Pondoh cold temperature storage. Snake fruits was obtained from Turi, Sleman, Yogyakarta and transferred to the laboratory with the aseptic condition. The sortation based on the visual method was used to collect the proper snake fruit. The cleaning using aseptic cloth was done prior to storage. The snake fruit was collected individually in refrigeration containers at temperatures of 10±5˚C. The storage was done for 30 days and it was stopped until appearance of physical damage in snake fruit. The result indicates that the storage using this method might extend the shelf-life of snake fruit until 28 days. However, snake fruit was hardly to peeled and dry. It can be concluded that cold temperature might extend the shelf-life of snake fruit.
