Abstract

White bread is the kind of food which contains high carbohydrates content, but it does not have omega-3 fatty acids.  The composition of omega-3 fatty acids can be increased by fortification with fish oil, as a source of omega-3 fatty acids.  However, the fish oil is very susceptible to oxidation, which causes changes in aroma and flavor, as well as affect the shelf life of the bread.  Therefore, addition of antioxidants into white bread fortified with fish oil is needed to maintain the sensory properties and extend the shelf life of the bread.  This study aimed to get the right combination of adding antioxidants to maintain the sensory properties and extend the shelf life of the white bread fortified with fish oil.  The research was arranged in Randomized Block Design Complete (RBDC) with two factors, that were combination of ascorbic acid and BHA (0% and 0,02% w/w; 0,005% w/w and 0,015% w/w; 0,01% w/w and 0,001% w/w; 0,0015% w/w and 0,005 w/w; and 0,02% w/w and 0, respectivelly), and storage time (0, 3, and 6 days).  All the data from the experiment were analyzed by Bartlett Test for equality of variance and Tukey Test for data additivity.  The data were analyzed by Analyzed of Variant to get the error variance estimators and differences between treatments.  The data were analyzed further by LSD Test to determine the best treatment.  The result showed that addition of the 0,010% w/w of ascorbic acid and 0,010% w/w of BHA into fortified bread produced the bread that had the best organoleptic properties and the lowest peroxide value.  Additionally, such treatment produced the bread that  could be stored for 3 days without changing its organoleptic properties significantly.Key words:  fish oil, fortification, omega-3, white bread.

Abstract

Trash fish is a fish with low selling value that needs an increased value by processing it into rusip (fermented fish) products. The research objective was to determine the effect of liquid palm sugar and salt concentrations on the physical, chemical, and microbiological properties of trash fish rusip. The research was arranged factorial in a completely randomized block design. The concentrations of liquid palm sugar were 5%, 10%, and 15% (v/w), while concentrations of salt were 20%, 25%, and 30% (w/w).  Using LSD at level 5% showed that the concentration of liquid palm sugar had a significant effect on total lactic acid bacteria and total lactic acid, while the salt concentration had a significant effect on pH and salt content. There was an interaction between two factors on the trash fish rusip water content, where the significant effect of liquid palm sugar concentration on water content was salt concentration-dependent.Keywords: chemical, microbiological, physical, rusip, trash fish.
