Lutgada S. Palomar and Lloyd B. Bullerman ABSTRACT Binagol (pH 6.3) was reformulated using lemon juice to lower the pH to 5.5, 5.0 and 4.5. Sensory evaluation was done to determine the acceptability of the binagol with lower pH, using the original binagol at pH 6.3 as the control. Sensory evaluation showed binagol can be …

Lemuel M. Diamante1, Jesebel P. Rosillo1and Remberto Patindol2 ABSTRACT This study was conducted to determine the effect of temperature on the drying rates and sensory qualities of sweetened maturing coconut meat called coco-crisps at ambient humidity, constant air velocity and tray density. The drying of sweetened maturing coconut meat at different temperatures (62-90°C) using an …
M.S. Nagaraja1 and V.R. Ramakrishna Parama2 ABSTRACT Evaluating the sustainability of any land use system poses challenging methodological questions. The study conducted at the University of Agricultural Sciences, Bangalore, India revealed that management practices under different land use systems have altered soil functions and processes. The biological changes observed in man-made systems relative to the …
Sabine Zikeli1, Victor B. Asio2 and Reinhold Jahn1 ABSTRACT Soils under rain forests are until now poorly understood. This study was conducted to determine if nutrient status is a limiting factor in the rain forest soils of Mt. Pangasugan in Leyte, Philippines. Four sampling sites at varying elevations in a representative catena were studied. In …
