Ready-to-Serve Crab Sandwich Spread in Retort Pouch: Product Development and Process Optimization

Abstract

A ready-to-serve sandwich spread was developed from the meat of mud crab, Scylla serrata, by thermal processing in retortable pouches in an overpressure retort at temperatures 111.1, 116.1, and 121.1°C; and F0 values 5, 6, and 7 min. Process optimization was done by evaluating the samples for texture, color, commercial sterility, thiobarbituric acid (TBA) value, and sensory evaluation. All samples were found to be acceptable based on these quality evaluations, and together with principal component analysis (PCA), the sample processed at 116.1°C, 6 min was found to be the best, with cook value of 84.29 and total process time of 42.59 min.
