Abstract

This research which had a purpose for studying a potency of lime juice as acidifier in the making of Mozzarella cheese was done to know its influence on Mozzarella cheese physical quality. The method used in this research was Completely Randomized Design. Optimum concentration lime juice as acidifier for making Mozzarella cheese repeated 6 times had variation treatment, including : P1 = 0.5%, P2 = 1.0%, P3 = 1.5%, and P4 = 2.0% (w/v). All variables examined were rendement, meltability, stretchability, and elasticity. Variation analysis on rendemnet and strechability of Mozzarella cheese showed that those variation  of lime juice gave no significant difference effect (P>0,05) on Mozzarella cheese physical quality. But, those treatments gave very significant difference effect (P<0,01) on meltability and gave significant difference (P<0,05) on elasticity Mozzarella cheese. The range of result of cheese rendement was about 11,76-12,17%. The highest meltability was resulted from the use of 2.0% lime juice and its value was 8,57. The highest elasticity was from the highest concentration of lime just 2,0% and its value was 63,64% and based on statistic gave significant defference (P<0,05) compared with other concentration.   Keywords : lime juice, Mozzarella cheese, acidifier

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.
