Abstract

This research aims to find out and determine the proper concentration of beef gelatine which used to produce high quality of frozen yoghurt based on the water holding capacity, melting time and organoleptic quality (texture and taste). The frozen yoghurt was made from fresh milk, sugar, beef gelatine, and yoghurt starter (L. bulgaricus and S. thermophillus). The method which used an experiment with Randomized Block Design (RBD). The treatment consist of 4 level of gelatine concentration and 3 groups, i. e; P0 (0%), P1 (0.2%), P2 (0.4%), P3 (0.6%). Data analysis by analysis of variance and followed by Duncan’s Multiple Range Test (DMRT) if there was any significant effect. The result of study showed that gelatine addition in frozen yoghurt gave water holding capacity average to treatment P0, P1, P2, P3 was 37.678%; 38.172%; 43.747%; melting time 126.000; 133.000; 147.333; 147.667 (minutes).The result of hedonic test to the frozen yoghurt texture was 5.750; 5.933; 6.167; 6.467 and taste was 6.583; 6.417; 6.417; 6.683; 6.950. It concluded that increasing of gelatine concentration gave significant effect on frozen yoghurt texture (P<0.05), did not gave the significant effect (P>0.05) on water holding capacity, melting time and taste of frozen yoghurt. It suggested to use 0.6% gelatine. Key words : frozen yoghurt, water holding capacity, melting time, gelatine.

Abstract

This study was conducted to investigate physical characteristics of various pig breed.  The materials used in this study were nine pigs (three Yorkshire, three Landrace, and three Duroc), and they were about 7 – 8 months old, weighing 90 – 100 kg. The meat examined, was  Longissimus dorsi muscle.  They were heated of 50oC, 75oC, 100oC. This study applied a Completely Randomized Design with a 2-factor nesting pattern using cooking repeatition for three times. The factors were pig breed and the cooking temperature degrees. The treatment indicating differences were examined by using Duncan Multiple Range Test (DMRT). The differences of pig breeds did not provide differences on quality for pH, WHC, cooking loss and Aw. Within quality differences (P<0.01), there would  be tenderness, elasticity, shear force, and meat water content. Cooking gave quality differences (P<0.01) on pH, tenderness, elasticity, shear force, WHC, cooking loss, Aw and water content. Cooking loss and water content decreased with the increase of cooking treatment temperature. Meat pH on the temperature of 50 oC decreased in comparison with raw meat and it would increase with the enhancement in cooking treatment. Tenderness, elasticity, shear force, and WHC of the meat decreased at 75 oC and they could get enhancement as the temperature achieving 100 oC. Duroc tended to have more tenderness, elasticity, and higher shear force rates in comparison with Yorkshire and Landrace. Keywords: Pig breed,  Cooking, Physical quality

Abstract

The objective of study was to investigated the number of bacteria in pasteurized milk packed by plastic and distributed in Malang Municipality. The results were compared with the standards, then. The material consisted of six different products obtained from six milk pasteurized agents. A survey research was carried out, and sampling of pasteurized milk was taken by simple random sampling and the agent was taken as total sampling. The number and type of bacteria were determined in the laboratory. TPC method was used to test the number of bacteria, MPN method on coliform bacteria, Gram colouring on bacterial identification, and TPC method on the number of bacteria in plastic packaging. Data were descriptively analysed. Compared with standard of pasteurized milk quality according to the standard regulated by government. The results showed the pasteurized milk packed by plastic distributed in Malang Municipality was unsuitable according to the standards with bacterial content and still found the coliform bacteria. It is recommended the need of agency which enable to control and testing for the products in Malang Municipality to keep quality and safety for the consument.   Keywords : bacterial count, pasteurized milk, plastic packaging.

Abstract

The materiasl used were duck eggs and curing agent. The research method used was factorial experiment (2x4) Randomized  Block Design with two treatment factors. The first factors was preservation which consisted of two levels namely : with (P1) and without (Po) dipping in water glass as preservative. The second factor was the length of storage which consisted of four levels namely : 0 day (L0), 14 days (L14), 28 days (L28) and 42 days (L42). Each treatment was devided into three groups based on the time of salting. The variables measured were microbial load, protein content and organoleptic qualities (flavour, colour of yolk and texture) of salted eggs. The result of statistical analysis showed that a highly significant different effect (P<0.01) of the length of storage on the microbial load, preservation and the length of storage on protein content and a significant effect (P<0.05) of the preservation and the combination treatments on the microbial load, the flavour and colour of yolk of salted eggs. The salted eggs experienced off flavour, changed yolk colour, and texture while storage for 28 days, neverthless panelist prefered its. The conclusion that the dipping in water glass as preservative and the different length of storage in room temperature affected on  microbial load, protein content and organoleptic qualities (flavour, the colour of yolk and the texture). Dipping in water glass as preservative would make salted egg's microbial load lower than the ones without preservative. A longer storage could increase the microbial load and decrease protein content. After 28 days of storage the egg's flavour and texture as well as yolk colour started to change, however, the panelist preferred its. It was suggested that never keep the salted egg preserved with water glass solution more than 28 days at room temperature.   Keywords: salted egg, water glass

Abstract

The objective of this study to find out the effect of gelatine addition as a stabilizer on acidity, pH, water holding capacity, and syneresis of yogurt. The material of these research were yogurt made from skim milk with 14% of total solid, yogurt starter which combination of Lactobacillus bulgaricus and Streptococcus thermophillus (1:1), and gelatine as a stabilizer. The method was experiment using Randomized Block Design, which the factor was the gelatine percentage (w/v) of 0 % (G0), 0.2% (G2), 0.4 % (G4), and 0.6 % (G6). The observed variables were syneresis, water holding capacity, acidity, and pH. Data was subjected to analysis of variance followed by Duncan’s Multiple Range Test. The result of analysis variance showed that the addition of gelatine did not gave  a significant effect (P>0.05) on acidity, significant effect (P<0.05) on pH and highly significant effect (P<0.01) on syneresis and water holding capacity of yogurt. It was concluded that the addition of gelatine as a stabilizer influences pH, water holding capacity and syneresis but gave no influence acidity of yogurt. The addition of 0,6% gelatine as a stabilizer could produce yogurt with low syneresis, high water holding capacity, and the normal pH.

Abstract

The purpose of this research was to find out physical properties of yogurt during storage at 4ºC. Yoghurt starters were using Lactobacillus bulgaricus FNCC 0041 and Streptococcus thermophilus FNCC 0040 (1:1). Yoghurt starter was inoculated on 10% (w/v) of skim milk and 10% (w/v) of skim milk which contained 5% (w/v) of sucrose, incubated at 42ºC for 6 hours then storage at 4ºC for 30 days. The result showed that posacidification until 6 days storage, pH tend constant between 6 days and 30 days. Until 9 days texture tend constant, but after 9 days storage texture tend decreasing. Storage yogurt at 10˚C for 12 hours before 4˚C gave higher viscosity, viscosity tend constant until 30 days storage. Water Holding Capacity increasing until 6 days storage, after 6 days tend constant. Sineresis increasing until 6 days storage, after 6 days tend constant. It concluded that physical properties of yogurt gave a little changes on first week storage, after that tend constant until 30 days storage.   Keywords: yogurt, pH, Texture, Viscosity, Water Holding Capacity, Sineresis
