Abstract

Jelly candy is a candy consist of sucrose, glucose, acid and gel performing material with a texture and certain elasticity. Calcium fortification will become added value on the product. Calcium needed on the bone performing and to prevent the osteoporosis. Protein and vitamin D contain from milk in milk jelly candy will increace the absorption of calcium on the body. The calcium carbonate adding will affect on jelly candy pH. pH will affect on the jelly performing which it can affect texture. Calcium can bound with protein perform calcium bridge which is strenghten texture. Unsolved of calcium will produce “chalky mouthfeel”, gritty in the mount and opaque appearance. This study will examine the effect of the difference of the adding calcium carbonate toward physic, chemical and sensory characteristic on the milk jelly candy and can be accepted by consumers. Milk jelly candy contain calcium which it made from gelatin mix, sucrose, glucose syrup, water, full cream powder milk and calcium carbonate. This study had done by the making of the milk jelly candy with variation on the adding of calcium carbonate. The study design were used is Group Randomized Design with single factor contain one factor: 4 level of calcium carbonate concentration (0,77%; 1,53%;2,30%;3,06%) with 6 replication. The examination including physical characteristic (texture, color), chemical characteristic (water content, pH, calcium content) and organoleptics (texture, taste, mouthfeel, colour). Organoleptics test using Completely Randomized Design contain 4 level of calcium carbonate concentration (0,77%; 1,53%;2,30%;3,06%) with 80 panelis. The obtained data came from the observation results then had been analyzed statistically by NOVA test α=5%. If the ANOVA shows the difference, then would be continued by Duncan Multiple Range Test. The best optional with weighing test. The parameter have been choose for the weighing test is organoleptics (texture, taste, mouthfeel, color). The result shows that different level of calcium carbonate gave significant differences of moisture content, pH, elasticity, compresibility, brightness, hedonic range of colour, taste, texture milk jelly candy, but did not gave significant differences of hedonic range of mouthfeel. The higher level of calcium carbonate, decreased moisture content of milk jelly candy, while pH, elsticity, compresibility, brightness were increase. The best fortification level of milk jelly candy was 3,06%, which gave hedonic score (organoleptics) of colour 5,77; taste 5,20; texture 5,20; mouthfeel 5,18; moisture content 15,85%, pH 7,80, compresibility 270,58 N/20mm, elasticity 4,92 N/50mm, brightness 59,15, calsium level 1,22%.

Abstract

Fungi merupakan mikroorganisme yang berperan dalam kehidupan manusia, organisme ini dapat menguntungkan maupun merugikan manusia, hewan, tumbuhan, dan lingkungan. Dalam industri pangan kapang dan khamir diaplikasikan untuk produksi pangan dengan fermentasi seperti tempe, kecap, bir, koji, sake, miso dan produk pangan yang lain. Dengan perkembangan ilmu bioteknologi fungi juga dieksploitasi untuk produksi enzim, anti bakteri, dan anti jamur, serta dipergunakan untuk produksi asam-asam organik. Dengan melihat peranan fungi yang besar dalam kehidupan manusia, penelitian tentang fungi berkembang dengan pesat. Salah satu penelitian yang banyak dilakukan adalah proteomik. Proteomik merupakan suatu penelitian identifikasi, separasi, maupun kuantitatif dari protein yang dihubungkan dengan gen yang bertanggung jawab akan pembentukan protein secara spesifik. Cara pemisahan yang paling banyak dilakukan adalah dengan gel elekroforesis SDS PAGE, untuk kemudian dianalisis dengan spektrometri massa MALDI TOF. Hasil yang didapatkan dari spektrometri ini kemudian diidentifikasi dengan darta-data genome yang telah tersedia. Faktor yang harus diperhatikan adalah ekstraksi protein yang tepat, prosedur elektroforesis yang benar, serta identifikasinya. Proteomik merupakan teknologi baru yang masih berkembang, teknik ini penting karena dapat mengetahui gen yang berpengaruh terhadap sekresi metabolit sekunder protein yang dapat berguna maupun membahayakan. Sehingga dengan mengetahui faktor yang berpengaruh, maka untuk produk sekresi yang berguna kita dapat meningkatkan produksinya dengan modifikasi gen maupun kondisi optimumnya.

Abstract

Bread is a cereal-based product, commonly from wheat flour and trough the process of mixing, fermentation, and baking steps until the changes in flavor, shape, and chemical composition occur. Wheat flour content gliadin and glutenin that form gluten which can cause an intestine inflammation in patients of celiac diseases. They should avoid to consume gluten so need gluten-free product such as gluten free bread. The Gluten-free bread made from rice flour, corn starch, and cassava starch with proportion of 74.2% cornstarch, 17.2% rice flour, and 8.6% cassava starch. In general gluten-free white bread has poor capability to retain gas from fermentation, so will has firm crumb, poor loaf and easy to be stahling. This condition can be improved by addition of hydrocolloid such as xanthan gum. Randomized Block Design (RBD) used in research. The treatment was concentration of xanthan gum 0.5%, 1%, 1.5%, 2%, and 2.5%. and repeated five times. Observation was done on water content, hardness, compressibility, specific volume, and preference tests for crumb pore, texture (mouthfeel), and moistness. The data were analyzed with Anova α = 5% and than continued with Duncan’s Multiple Range Test (DMRT) at α = 5% when the treatment gave significant influence. The best treatment is determined according to the Effectiveness Index. The result showed that the use of xanthan gum has no effect on the water content of bread, but influence the hardness, compressibility, specific volume, and sensory evaluation of gluten-free white bread made from cornstarch, rice flour, and cassava starch. The higher the concentration of xanthan gum results in higher value of hardness, compressibility, and specific volume of gluten-free bread. The treatment of 2% xanthan gum showed to give the best gluten free bread with 23.89% of water content, 23.8 N of hardness, 98.02% of compressibility, 2.1675 cm3/g of volume specific, and give the best score in preference test.

Abstract

The aim of this study is to know the effect of sodium alginate concentration in Lactobacillus acidophilus FNCC 0051 entrapment, refrigeration storage (±5oC) period and interaction of both factors on the number of released cells and carrier’s character (UHT milk). The experimental design used was factorial RBD (Randomized Block Design) design with two factors, sodium alginate concentration (1%, 1,5%, 2%) and storage period (0,10, 20 days). The parameters observed are the number of released cells (Total Plate Count / TPC), pH and total lactic acid of the carrier (UHT milk). The obtained data are statistically analyzed by ANOVA (Analysis of Variance) at α=5% and continued with Duncan’s Real Difference Distance test (Duncan's Multiple Range Test) to determine which level of the treatment that gives a significant differences. Sodium alginate concentration and storage period had significant effect on the number of released cells and carrier’s character (pH and total lactic acid of UHT milk) and there is interaction between both factors. The lower level of sodium alginate concentration increased the number of released cells, decreased pH value and increased total lactic acid. During 20 days storage, the amount of released cells and acidity of carrier increased than 0 and 10 days. Interaction between both factors which give the less number of released cells (3,7948 log cfu/ml) and carrier’s character changes (pH = 6,4767 and total lactic acid= 0,0741 %) is combination of 2% sodium alginate concentration in 0 days storage.
