QUALITY OF GIANT SWAMP TARO (CYRTOSPERMA MERKUSII) CORM JAM AS AFFECTED BY VARIOUS INGREDIENT PROPORTIONS

Abstract

The study aimed to investigate the quality of prepared giant swamp taro corm jam on various ingredient proportions. Modeling procedure were made for the ingredient proportion 1 and for the ingredient proportion 2 of GST corm jam and were evaluated using the 9-point Hedonic Scale Organoleptic test by panel of experts as evaluators. Linear Programming Method were utilized and Analysis of Variance were used to interpret the data gathered. Study revealed that as the evaporated milk ratio increases together with the ratio of all-purpose cream increases, the consistency of the jam becomes weak leading to non- sticky mixture that caused for the ingredient proportion 2 to be rated slightly like compared to the first ingredient proportion for the preparation of giant swamp taro corm jam which obtained the higher rating for acceptability using sensory test as rated by experts’ panel as evaluators. This finding implied that ingredient proportion 1 for making excellent jam for GST is best ingredient in preparing GST corm jam and could possibly earn more income as far as profit maximization is concerned. The optimizations were successful in fulfilling a model recipe for GST corm and provided a feasible and promising recipes that is acceptable with its appearance, taste, texture, color and odor. Finally, although making giant swamp taro corm jam was tedious due to the lack of technology for ease and convenience of the preparation, GST corm can be used for food consumption and income generating like other root crops. Therefore, proper formulation of ingredients can help control the quality taste of the product which can pave way to produce more GST Corm jams as evident in the linear programming methodology hence, provided a systematic tool for testing the level of acceptability. Study showed that there is a significant difference on the taste, color, odor, appearance. It can be concluded that ingredient proportion 1 be introduced in the market since it has a promising potential for food consumption, income generating paving way to counter hunger, for food safety and for poverty alleviation to attain improvement of quality life as our response to our quest for the “Ambisyon Natin 2040.”
