ABSTRACT MADRIAGA, REINA MAE A, 2021. Effects of Freeze Drying on the Acceptability of Powdered Bagoong and Garlic (Allium sativum) in Pakter Dish Mariano Marcos State University City of Batac 2906, Ilocos Norte. 44pp Undergraduate Thesis. College of Agriculture, Food and Sustainable Development Adviser Prof. Efren T. Renon Jr. The study was conducted at the Food Products and Innovation Center of the Mariano Marcos State University, City of Batac, Ilocos Norte from March 2021 to September 2021. The study generally aimed to develop an instant pakbet seasoning mix formulated from garlic and bagoong. Specifically, it aimed to: 1) compare the acceptability of the pakbet by using powdered hagoong and garlic against the original pakbet dish through sensory evaluation and 2) determine the cost of production of the instant seasoning mix. Two treatments were used: control - original pakhet dish (OPD), and treated pakbet dish with powdered (PDWP) bagoong and garlic. The sensory acceptability of the product was evaluated by panelists from all walks of life. Scorecard that described the color, aroma, taste, and overall acceptability was used during the sensory evaluation. Results of the study indicates that freeze drying affects the sensory acceptability of powdered bagoong and garlic as applied to pakbet dish. Furthermore PDWP with 4 8% concentration (w/v) is more preferred and acceptable among the panelists (n=30) than the control (OPD). Calculated production cost is at Php 82.91, which is significantly higher than the locally available instant seasoning mix. The cost of production was affected by the laboratory scale production, however, the price could go down if it will be the production will be produced in very large amount per batch. Hence, the product may have a potential for commercialization As a recommendation, conduct of physico-chemical analyses and exploration of the feasibility of other drying techniques such as air drying and spray drying to have a comparison in terms of acceptability and cost production to determine which one is the most advantageous.
