The effect of liquid smoke treatment from plant leaves materials for latex

Abstract

Abstract When materials high in carbon and other chemicals are burned, either directly or indirectly, the process of pyrolysis or steam distillation yields liquid smoke. Leaves, bark, stems and waste from wood processing industry can be used for liquid smoke as raw material. Several benefits of liquid smoke can be observed, such as its applications as food preservatives, plant fertilizers, increasing plant productivity and acting as rubber thickener. The aim of this study was to evaluate the effectiveness of plant-derived liquid smoke as a thickener for latex. The process of latex thickening involves the combination of 50 ml of latex and 5 ml varying concentrations (30, 40 and 50%) of grade 1, 2 and 3 liquid smoke. Subsequently, careful observations were made regarding the time required for thickening, the resulting texture and color, as well as the odor of the latex. The results showed that thickening of latex using grade 3 liquid smoke from Mango leaves had a shorter curdling time and better thickening conditions compared to other grades and control. Latex thickening using grade 1, 2 and 3 liquid smoke produced latex with a soft texture, white color and odorless.
