Abstract

AbstractThis study aimed to determine the effect of different temperatures on the effectiveness of brown seaweed extract (Sargasum plagyophyllum) as an antibacterial agents for Staphylococcus aureus and Pseudomonas aeruginoosa. The treatment conducted was heating the extract with  varied temperatures (50, 60 and 70 ºC). The parameters assessed were the clear zone diameter on each medium for Staphylococcus aureus and Pseudomonas aeruginosa bacteria. The results showed that the extracting the brown seaweed at the temperature of 70 ºC was the most effective treatment to inhibit the growth of Staphylococcus aureus and Pseudomonas aeruginosa bacteria with an inhibition zone diameter of 4.31 mm of 8.30 mm, respectively. Keywords: Antibacterial, Pseudomonas aeruginoosa, Sargasum plagyophyllum and Staphylococcus aureus

Abstract

The aim of the research was to evaluate effect of soaking baraccuda fish stick into the liquid smoke at varied concentration on the consumer acceptance and to determine the optimum concentration of liquid smoke in the processing of smoked fish sticks. The treatment given was soaking the fish into the liquid smoke solution at varied concentration (0%, 4%, 8%, and 12%).  The parameters used to evaluate the product were sensory evaluation (appearance, aroma, texture and taste), water content, the content of total phenols, and total acids. The best product of smoked fish sticks was shown by the treatment of soaking the fish into the liquid smoke solution at the concentration of 8%.  It was indicated by the most number of panelist (95%) preferred to this product that characterized long flat appearance and a yellow-gold color (score 6.8), a distinctive smoky aroma suitable to the fish aroma (score 6.8), crunchy texture (score 6.8), and a distinctive taste of smoked fish (score 6.9). The product contained the water 1.68%, total phenols 12.8 ppm, and total acids 1.25%.

Abstract

ABSTRACTThis research was aimed to determine the effect of different ways of chitosan coatingon the quality of smoked catfish (Pangasius hypophthalmus) during room temperaturestorage. The method used in this research was experimental method, with coating of chitosanin different ways to smoked catfish; without treatment (K0), spraying with 2% of chitosanconcentration (K1), and brushing with 2% of chitosan concentration (K2). Smoked catfish wasobserved to organoleptic test appearance, odor, flavor, texture; moisture content, proteincontent, fat content, peroxide value; identification of fungi and bacteria Staphylococcusaureus. The results showed that smoked catfish (Pangasius hypophthalmus) was coated withbrushing 2% of chitosan concentration could slowdown the deterioration smoked catfishquality during room temperature storage, with organoleptic value of appearance, odor, flavor,and texture was 6.78, 6.74, 6.72 and 6.84 respectively. Proximate value, also could slowdownthe deterioration in protein content (34.44% to 29.97%) and fat content (31.60% to 24.39%).Its could inhibit the increasing of moisture content (10.09% to 15.37%) and peroxide value(0.00mg ek/1000g to 7.38mg ek/1000g); the fungus Aspergillus sp and Staphylococcusaureus were not found during room temperature storage.Keywords: smoked catfish (Pangasius hypophthalmus), chitosan liquid, storage.

Abstract

ABSTRACTThe objective of the research was to determine the effect of the different packaging materials on the quality of seaweed jelly candy during storage at room temperature. The method used was the experimental method and the design used was non factorial Randomized Block Design (RBD). The treatment conducted was packing the seaweed jelly candy with 2 varied packaging materials (HDPE and a combination of aluminum foil and HDPE). The results showed that the candy packed with HDPE obtained the score of appearance 6.62 (whole, neat and quite clear brownie), aroma 6.73 (slightly fresh typical of grass jelly candy), texture 6.64 (slightly chewy), taste 6.55 (slightly sweet and acidic). The candy contained moisture 17.64% and reducing sugar 16.97%. The value of folding test was 3.33 and the number of molds growth was 4.3 x 102 colonies/g). Meanwhile, the candy packed with combination of aluminum foil and HDPE obtained the score of appearance 6.32 (intact, neat and dark brown), aroma 7.34 (quite fresh typical of seaweed jelly candy), texture 6.70 (chewy typical of seaweed jelly candy), taste 6.95 (quite sweet and acidic). The candy contained moisture 17.48% and reducing sugar 20.37%. The value of folding test was 3.66 and the number of molds growth was 3.4 x 102 colonies/g). Thus, it can be concluded that aluminum foil combined with HDPE is the best packaging materials used for storing seaweed jelly candy for 28 days at room temperature.Keywords: Candy Jelly, Gracilaria sp., Packing, , Storage
