however, proved that there were no significant differences between the amounts of gas produced by the experimental groups. #42 Horse manure as a substitute for wood charcoal Dante del Rosario, Andrew Fañega, Farley Aguila, Raymond Santiago, Carlos Espiritu ABSTRACT The study aimed at the technical feasibility of producing charcoal from horse manure using locally available binder-corn starch. Briquettes with cornstarch mixture binder had higher crushing strength compared to briquettes can then be made into charcoal by simply drying the materials to constant weight. The amount of heat emitted per volume results indicated that the production of charcoal briquettes from horse manure is feasible using cornstarch. But the heating capacity of pure manure is greater than the heating capacity of the manure with cornstarch as binder. The product can only be used as a source of energy for incubators. #43 Improving the quality of cheese made from mixed mold rennet extracts Lani Rose San Mateo, Joey Roque Boiser, Afzelia Thersa Busa, Abelardo Perez Jr, Lynn Redoble ABSTRACT Mold extracts from Aspergillus niger (strain 3704) cultured in potato dextrose agar (PDA) and Czapek-dox agar (CDA); and Rhizopus oryzae (strain 3356) cultured in rice bran (RB) and copra meal (CM) were combined in five different ratios, producing 16 combinations of mixed mold rennet extract. These 16 combinations were reduced to two best combinations for cheesemaking based on milk clotting activity (MCA) milk clotting time (MCT) and percentage yield, namely: 5.0 Cm : 5.0 CDA and 5.0 CM : 5.0 PDA. Cost analysis showed that the experimental samples at P14.64/100 g and 13.74/100 g (treatments with and without lactic acid, respectively were more expensive than the control at 8.00/100g. However, with the use of carabao’s milk, costs may be substantially reduced. Addition of lactic acid from Streptococcus sp. showed no effects on shelf life and did not significantly affect the percentage yield. Furthermore, there was no recognizable trend in terms of crude protein and fat content, but the general acceptability of cheese made from mixed mold rennet extracts was improved. The Wilcoxon’s signed-rank test showed that the most acceptable proportion for cheesemaking is 5.0 CM: 5.0 CDA with lactic acid. Its crude fat content (9.42%) ranked highest among the experimental samples and only
two percentage points lower than the fat content of DTRI-made cheese. It crude protein content is 15.18% compared to the DTRI-made cheese having 18.80% crude protein. #44 A comparative study of the lipid content of leaves from selected species of the malvaceae family Claudine Tanbuatco, Jeanne Bernardino, Eric Domingo, Cielo Echevarria, Rommel Galsim ABSTRACT Lipids extracted from Urena lobata, (dalupang); hibiscus rosasinensis, (gumamela); Abelmoschus esculentus, (okra); and abelmoschus moscatus, (kastuli) were subject to a comparative analysis in terms of lipid percentage yield were: okra, 13.7%; kastuli, 12.3%; dalupang, 10.5% gumamela, 19.3%. The values obtained for iodine number were : okra, 105.08; dalupang 95.02; gumamela, 95.91; kastuli, 117.40. Results of the t-test on the percentage yield of lipid showed that there was a significant difference between the percentage yields of gumamela and dalupang, in favor of gumamela; kastuli and gumamela, in favor of gumamela. No significant difference in terms of lipid percentage yield was found between okra and dalupang, okra and gumamela, okra and kastuli, dalupang and kastuli. Gumamela was found to have highest lipid percentage yield. Results of the ttest of the iodine values obtained showed that there was a significant difference between iodine numbers of okra and dalupang, in favor of dalupang; kastuli and dalupang, in favor of dalupang; okra and gumamela, in favor of gumamela; kastuli and gumamela, in favor of gumamela. No significant difference in terms of iodine number was observed between okra and kastuli; dalupang and gumamela. Based on the range of iodine values of common lipids with known uses, dalupang and gumamela may used as salad oil, vegetable shortening, soap, and in the manufacture of margarine; okra maybe used as shortening, margarine, salad oil, cooking oil, and in fatty acid production; kastuli may used as salad oil. However, confirmatory tests as to the actual use and efficiency of these lipids must first be conducted. #45 Utilization of oyster shells in block making Lloyd Tronco, Emmanuel Magboo, Ramil Andaya, Archemedes Quirante ABSTRACT Briefly discussed is how oyster shells were utilized in block making as to improve certain properties of the block, specifically the compressive strength and water absorption. The results of the analysis made on the blocks showed that the block containing 20% oyster shells yielded the highest mark in the test for compressive strength with a rating of 213.84 kg/cm 2 .
