<p>Catfish is one of the main commodities in fresh water aquaculture. Indonesia catfish<br />production increased 37,49% in 2010 until 2014. Protein content of catfish is 17.7-26.7%<br />and fat about 0.95 until 11.5%. The objective of this study was to determine the best<br />organoleptic and to study the changes of tissue structure of catfish caused by process precooking<br />and smoking process. Precooked Catfish with variation 5, 10 and 15 minute;<br />temperature of 100oC, and smoked for 7 hours with a temperature of 90°C, analyzed in<br />laboratory.

The purpose of this research was to observe the effects of threadfin breams surimi (Nemiptarus nematophorus) and mussel (Pilsbryoconcha exilis) to physical, chemical and sensory characteristics of nugget. This research used randomized block design (RBD) consisted of one factor treatment and three replications. Factor treatment consisted of combination ratio threadfin breams surimi and mussel 100% : 0%, 75% : 25%, 50% : 50%, 25% : 75%, 0% : 100%. The variables observed were physical characteristics (elasticity), chemical characteristics (moisture content, ash, protein, fat, carbohydrate, and iron) and sensory analysis on appereance, flavour, taste and texture of the final products. Different combinations of threadfin breams surimi and mussel had significant effect on elasticity (222.53 gf, 278.33 gf, 300.66 gf, 312.13 gf, 452.86 gf), ash content (3.26%, 2.51%, 2.23%, 1.63%, 1.45%), protein content (8.27%, 12.11%, 14.8%, 17.14%, 20.73%), carbohydrate content (17.32%, 14.34%, 11.11%, 8.42%, 3.5%), and iron (23.61%, 18.56%, 12.77%, 7.24%, 1.54%). Based on the results, the greater addition of surimi concentration caused the increasing value of elasticity, protein, and water content. While the greater addition of mussel concentration resulted on the increased value of ash, fat and iron. This research showed that the combination of 75% threadfin breams surimi and 25% mussel produced on nugget with the best characteristics.

The aim of this study was to determine the characterization of shredded mureel fish with kluwih substitution on water content, protein content, fiber content and organoleptic (preference for crispness and taste). This study uses a simple Randomized Complete Design (RCD) with the substitution treatment of kluwih and mureel fish, with the following ratio: S1 (240g: 60g), S2 (210g: 90g), S3 (180g: 120g), S4 (150g: 150g), S5 (120g: 180g). Data were analyzed statistically by analysis of variance and if there was a significant effect, further testing was done with BNJ at the level of 5%. The results showed that kluwih substitution in the manufacture of mureel fish shredded had an average: water content of 8.33-10.62%, protein :16.83-22.00%, fiber : 6.79-6.99%, score crispness 2-6.12, taste score 2.6-6.6. Based on the results of the analysis of the variety of kluwih substitutes and mureel fish have a significant effect on water content, protein content and crisp organoleptic test, taste on mureel fish fillet, and no significant effect on fiber content. The best kluwih substitution in S3 treatment with 120 grams of substitute kluwih and 180 grams of mureel fish.

Background: Instant pumpkin cream soup enriched with tempeh had fulfilled 10% Recommended Dietary Allowances (RDA) for elderly so that it can be used as an easy-to-serve snack, but decreasing quality of instant cream soup will be happened if the instant cream soup was stored for a long time. Objectives: This study aimed to analyze quality of water content, water activity and lipid oxidation in instant pumpkin cream soup during storage and estimated the shelf life of pumpkin cream soup enriched with tempeh.Method:  Quality storage was analyzed using of water content, water activity (aw) and lipid oxidation. Estimation of shelf life was analyzed using Arrhenius Accelerated Shelf Life Testing (ASLT) model.Results: The results showed that the water content, aw levels and lipid oxidation of instant pumpkin cream soup increased during the storage period. The critical parameter used in this study was lipid oxidation. Instant cream soup without the addition of tempeh can last 447 days  while the cream soup with the addition of tempeh has a shelf life of 433 days.Conclusion: Quality of instant pumpkin cream soup decreased during the storage period and it would be expired over a year.

Transient water transport experiments on Nafion of different thicknesses were carried out in the temperature range of 30 to 70 °C. These experiments report on water transport measurements under activity gradients in the time domain for liquid and vapour equilibrated Nafion membranes. Using a permeability test rig with a gated valve, the water crossover was measured as a function of time. The typical response is shown as a time dependent flux, and it shows the dynamic transport from an initially dry condition up to the final steady state. Contrarily to previous reports from dynamic water transport measurements, where the activity gradient across the membrane is absent; in this work, the membrane was subjected to an activity gradient acting as the driving force to transport water from an environment with higher water activity to an environment with lower water activity through the membrane’s structure. Measurements explored temperature and membrane thickness variation effect on the transient response. Results showed dependency on temperature and a slower water transport rate across the vapour-membrane interface than for the liquid-membrane interface. These measurements showed the transport dependency on water content at the beginning of the experiment when the membrane was in a close-to-dry condition suggesting a transport phenomenon transition due to a reached critical water content value. The new protocol for transient measurements proposed here will allow the characterization of water transport dependency on membrane water content with a more rational representation of the membrane-environment interface.
