The experimental method of research was used with survey questionnaire as the data gathering instrument. The results revealed that the three groups of respondents, namely Food Experts, Sellers, and Consumer had different evaluation as regards the level of acceptability of the 25g and 75g proportion, while the 50g proportion was evaluated as Very Acceptable by the three groups. In addition, the respondents evaluated the level of marketability of the product as to Consumer Demand, Production Cost and Supply Availability as More Preferred. Comments and suggestions were provided by the respondents to further improve the product.","abstract_source":"original","authors":["Thommy Laurence Dela Paz Esteron"],"date":"2023-10-13","doi":"10.5281/zenodo.8437372","id":2121,"issue":4,"journal":{"issn":"2822-4353","name":"Psychology and Education: A Multidisciplinary Journal"},"pdf_sha256":"9a6336b993d17eb3b57f21180506feb2fab02e4e513768c135784b0044812766","schema":"scimatic-article/1","title":"Acceptability and Marketability of Tomato, Carrot and Moth Beans as Flavors of Ice Cream","volume":14}
