Karakteristik Fisiko-Kimia Dan Mutu Sensoris Skin Lotion Rumput Laut (Eucheuma Cottonii) Dengan Penambahan Kolagen Ikan Komersil

The purposes of this research were to know the physicochemical characterirics and sensory quality of seaweed skin lotion (Eucheuma cottonii) by adding fish commercial collagen. This research used a factorial randomized block design (RAKF). Treatments this research were by combining of seaweed (0%, 2,5%, and 5%) and fish commercial collagen (0%, 2,5%, and 5%). The parameters in this research were the analysis of physical, chemical, and sensory. For sensory analysis using Friedmen test. The results of this research on pH and color parameters have a significant effect only when the addition of collagen with different concentrations, whereas the viscosity parameter and weight shrinkage give significant effect with addition on of seaweed and collagen with different concentrations. For pH values 6,50-7,41; viscocity 6000 cp – 9000 cp; whiteness 65,30%-76,77%; weight shrinkage 1,78%-5,95%; emulsion stability 100% and sensory assessment on all the attributes was ranged between kind of like to like by doing. The best treatment to the addition of seaweed 5% and collagen 5% (R2K2)

Pengaruh Suhu Dan Lama Perendaman Dalam Air Dingin Pada Praperebusan Terhadap Kualitas Bakso Ikan Patin (Pangasius Pangasius)

This research studied about the effect of temperature and immersion time in cold water to the quality of catfish (Pangasius pangasius) meatball. This study used a factorial randomized block design models with two factors that were the temperature of water immersion (4 °C, 16 °C, 26 °C) and the immersion time (5, 15) minute. Each treatmens were repeated twice. Parameters observed were chemical analysis that includes moisture content, fat content, protein content and physical analysis that includes the gel strength, expressible moisture, microstructure and sensory analysis in the form of hedonic quality test. The results showed that the treatment temperature and immersion time significantly (p<0.05) affected the water content, gel strength, expressible moisture and sensory, while the levels of protein and fat were not significant. Based on microstructural observations using a SEM (Scanning Electron Microscope) show the structural differences between the samples treated and treated not. The best treatment is the treatment temperature of 4 °C and immersion time of 5 minutes
