Judul: Pengaruh Penggunaan Pati Sagu Resisten dan Enzim Lipase terhadap Karakterisasi Fisikokimia dan Organoleptik Keju Lunak Rendah Lemak
Abstrak: Low fat soft cheese usually have low textures and scents. Resistant starch as fat imitate can be used to improve the texture of cheese, while the enzyme lipase is known serves to break down or hydrolyze milk fat and give the flavor of cheese. The purpose of this research is to study the use of sago resistant starch and lipase enzymes for physicochemical and organoleptic characterization of low-fat soft cheese. In this study, the treatment was of cheese using sago resistant starch, cheese using lipase enzyme, cheese using a combination of increased sago resistant starch and lipase enzyme, and control cheese as a comparison. Hedonic test results for low fat soft cheese indicated that the percentage of acceptance the taste, the texture, the smell, the aroma of chewable, texture press, color, and general acceptance ranges between 22 %-94 % and the best treatment is cheese using lipase enzyme. The best low fat soft cheese had total lipid content is 21.9 % (dry basis), higher levels of unsaturated fatty acids linoleic (41.19 %) and linolenic (3.85 %), so that it have potential to decrease total trigliserida and cholesterol blood levels at who someone has lipid blood content syndrome (hyperlipidemic).

Abstrak: Milk with a high fat and protein content can be used in cheese production. Initially, cheese products in Indonesia are imported for supply the specific consumer. However, the cheese has become a kind of common food for Indonesian people. Cheese is usually consumed as a supplement and a flavor enhancer of food. This growing triggers some dairy-based food industry in Indonesia to produce cheese and its diversification. The diversifications are ranging from fresh to processed cheese. One of innovation product is the probiotic cheese products. This study used three different types of lactic acid bacteria: 1) Lactobacillus acidophilus RRM-01 (LA-RRM01), 2) Bifidobacterium longum RRM-01 (BL-RRM01) and 3) Lactococcus lactis DSB 42 (LL-DSB42) to produce a functional cheese product by fermentation of lactic acid bacteria. Analysis was performed on the quality of fresh milk using a pH meter and milko tester, bacterial culture are prepared by refreshment and propagation, soft cheese production by the addition lactic acid bacteria cultures. The analysis of the products includes physical (yield), chemical (pH, moisture content, protein rude, crude fat and ash) and microbiological (lactic acid bacteria). The research used the factorial completely randomized design in three replication. The parameters are pH value, carbohydrate, LAB population. Analysis of crude protein, crude fat, moisture content were performed by randomized block design (RBD). The data were collected from seven treatments of lactic acid bacteria culture (LA-RRM-01/LA, BL-RRM-01/BL, LL-DSB 42/LL, BL-LA, BL-LL, LA-LL and BL-LA-LL). The data were analyzed by analysis of variance (ANOVA) and followed by Duncan test for multiplication comparison test. The Sensory analysis was tested by non-parametric analysis. Fresh milk quality of FH cows with a fat content (4.9%), protein (3.8%), lactose (4.0%) and pH (6.7) is accordance with the SNI 314.1:2011 standard. The cheese was produced contain the yield ranging from 17.9% -22.5%, pH values from 5.10 to 5.79, and classified as soft cheese. The treatment did not effect in moisture content, crude protein and ash, but there were significant differences (P <0.05) in the carbohydrate and crude fat either in single culture or culture of the three bacteria. The use of single culture bacteria or in a mixture did not inhibit the other cultures. The population of lactic acid bacteria in the products is approximately 9 log10 cfu g-1. The hardness product cultured by mixed two bacterial cultures were significantly different (P <0.05) with that of three bacterial cultures. Fifty panelists gave neutral and like slightly assessment for the color, flavor, aroma and general preferences of soft cheese (value 3.6 to 5.3), dislike slightly for the appearance of texture (value 2.5 to 3.6). Panelists assessment of the hedonic quality were white-yellow (value 5.0 to 6.1), bitter-sour taste typical cheese-(value 4.4 to 5.0), the typical cheese-sour aroma (value 5.3 -5.6), texture (value 5.2 to 6.4) and consistency (value 5.3 to 7.1). Because of high water content in all the soft cheese products (> 55%) and looks watery consistency, the texture of the products is less preferred by the panelists. Panelists felt bitter and sour after taste. It was concluded that the milk used for cheese production meets
