Characterizations of milkfish (Chanos chanos) meatballs as effect of nanoencapsulation liquid smoke addition

Milkfish meatballs are one of the value-added product that is potential to be developed because this product is favored by consumers. The aims of this study were mainly to evaluate the effect of nano encapsulation liquid smoke addition to the properties of milkfish meatballs. The different concentration (0%, 1%, 3% and 5%) of nano encapsulation liquid smoke was treated into milkfish meatballs with three replications. Test parameters used include texture (hardness, deformation and gel strength); proximate (moisture, protein, fat, ash and carbohydrates content); sensory (organoleptic and hedonic). Parametric data were analysis using ANOVA and non-parametric parameters using Kruskal Wallis test. Analysis of variant shows that nanoencapsulation gave significant effect on the hardness, deformation, and gel strength; protein, lipid, ash and water content(P 0.05). The best texture characteristic was obtained by milkfish meatball added with 1% of nanoencapsulation liquid smoke indicated by the moisture water; protein; fat; ash and carbohydrate content: 66,35%; 12,69%; 6,75%; 2,42% and 5,93% respectively. The best organoleptic and hedonic value of milkfish meatballs was achieved by a panelist at the sample with the addition of 1% liquid smoke, but this sample found gave no significance different to control in terms of sensory valle.

The Addition of Ammonia Solution with Different Concentrations in the Sperms on the Percentage Ovulation Egg of Abalone, Haliotis asinina

The aim of this research was to know the impact of addition of ammoniak in different concentration in the sperm on the percentage of egg ovulation. The research method was carried out by completely randomized design with four treatments and three replicates, respectively. Those treatments were the addition of ammoniac solution with concentration of 0% (treatment A), 0.005% (treatment B), 0.010% (treatment C), and 0.015% (treatment D). The data was analyzed by using ANOVA and Duncan’s Multiple Range Test to know the effect of between the other treatments. The results showed that was the highly significant difference effect (p<0.01) on the egg ovulation of Abalone (H. asinina). The highest egg ovulation rate was obtained in treatment B (94.67% ). The ovulation rate was significantly higher than those in treatments C, D, and A, respectively. According to the results, the best concentration of the ammonia solution to the abalone sperm added was 0.005%. Furthermore, the regression test also showed a positive, linear relationship between spermatozoa motility rate and egg ovulation rate. However, the analysis of orthogonal polymonial provided a ammonia solution with the highest ovulation rate of 0.0057%. Keywords: Concentration, ammonia solution, ovulation egg, abalone, H. asinina
