No full textWhite bread is one type of bread that contains low amount of sugar and generally consumed daily. So far, white bread is used as a source of carbohydrates only, since other nutrients present in very small amounts. One effort to improve the nutritional value of white bread is fortified with omega-3 fatty acids, derived from fish oil. The purpose of this study was to determine the amount of fish oil added and storage time of white bread in order to produced white bread that contained high level of omega-3 fatty acid and good sensory properties. This research was arranged within a Complete Randomized Block Design in factorial with three replications. The first factor was the amount of fish oil added (0%, 1%, and 2%) and the second factor was the storage time (0, 1, 2, and 3 days). The data were analyzed using Bartlett test for homogeneity and Tuckey test for additivity. The data then were analyzed by using ANOVA to see the differences between treatments and analyzed further using LSD at 5% level to determine the best treatment. The results showed that the white bread obtained by adding 1% fish oil and 0 days storage time resulted as the best treatment with total omega-3 fatty acid 1.27%, aroma 4.43 (less fishy), taste 4.02 (less taste fish oil), texture 4.23 (soft), and the overall acceptance was 3.95 (like).Keywords: fish oil, fortification, omega-3, white brea

No full text ABSTRACTBagasse, solid waste by product of sugar cane industries, contains high lignocellulose consisting of 46.3% cellulose, 23.0% hemicellulose and 19.7% lignin. The bagasse can be converted into bioethanol after pretreating with base and acid and then fermenting with microbes. The objective of this study was to find out the effects of sodium hydroxide pretreatment and sulfuric acid hydrolysis on bagasse reduced sugar content. In this study, there were 2 treatments with 3 replications. The first treatment was submerssion bagasse into 1.0 NaOH solutions at a temperature of 121oC for 15 minutes. The second treatment was concentrations of sulphuric acid (H2SO4) that consisted of 5 levels, i.e. 0 M, 0.05 M, 0.10 M, 0.20 M, and 0.30 M. One and an half grams of dried and ground bagasse was put into 100 mL Erlenmeyer flash and then added with 30 mL 1.0 M NaOH solution. The flash was heated at a temperature of 121oC for 15 minutes. After filtering, the residue was hydrolyzed with H2SO4 solution. The residue as well as 1.5 g dried and ground bagasse without pretreating with NaOH was hydrolyzed with 15 mL H2SO4 at concentrations of 0, 0.05, 0.10, 0.20, and 0.30 M at a temperature of 121oC for 15 minutes. Filtrates of the solutions were taken to analyze their reduced sugar content. Reduced sugar content of the bagasse samples ranged from 0.05 to 4.20 mg/100 mL. The highest reduced sugar content (4.20 ml/mL) was yielded when bagasse was directly, hydrolyzed with 0.05 M H2SO4 at a temperature of 121oC for 15 minutes.Keywords : Bagasse, bioethanol, lignocellulose, sulphuric acid, reducing suga
