dc.description.abstractTHIS STUDY AIMED TO EVALUATE THE EFFECT OF HIGH PRESSURE IMPREGNATION (HPI) (PRESSURE: 350, 450, AND 500?MPA; TIME: 5 MIN; OSMOTIC SOLUTION: 15% NACL) AS A PRETREATMENT TO THE DRYING PROCESS OF ABALONE SAMPLES (TEMPERATURE: 60°C) AND SUBSEQUENT EVALUATION OF PHYSICOCHEMICAL PROPERTIES THEREOF. THE PROTEIN CONFORMATIONAL CHANGES OF HPI-DRIED SAMPLES WERE EVALUATED BY FOURIER TRANSFORM INFRARED (FT-IR) SPECTROSCOPY. THE MOLECULAR WEIGHT PROFILE AND AMINO ACID COMPOSITION WERE DETERMINED. THERMAL ANALYSIS WAS PERFORMED BY DIFFERENTIAL SCANNING CALORIMETRY (DSC). PROCESS DRYING RATES WERE REDUCED UP TO 33%, AND DRIED ABALONES HAD LOWER MOISTURE CONTENT AND WATER ACTIVITY AS THE PRESSURE LEVEL INCREASED. IN ADDITION, LESS DEGRADATION EFFECTS WERE FOUND IN AMINO ACID COMPOSITIONS. IN THE ?-SHEET STRUCTURE, HPI-ASSISTED DRYING PROCESS CAUSED PARTIALLY FOLDED CONFORMATIONS AT 350 AND 450?MPA, AND AGGREGATION AT 500?MPA. A COMPACTED STRUCTURE WAS IDENTIFIED AS PRESSURE INCREASED (350 ? 500?MPA), CONFIRMING THAT THE STRUCTURE OF ABALONE MUSCLE TREATED WITH HPI-ASSISTED DRYING DIFFERED SIGNIFICANTLY FROM RAW MATERIAL. THE RESULTS PRESENTED IN THIS RESEARCH COULD SUPPORT THE POTENTIAL APPLICATION OF HIGH HYDROSTATIC PRESSURE TREATMENT AS COMBINED TREATMENTS FOR OTHER COMPOUND IMPREGNATION UNDER HIGH PRESSURE. IN ADDITION, HPI TECHNOLOGY COULD BE USED TO ENHANCE THE QUALITY PROPERTIES OF DRIED ABALONES AND DRIED MARINE PRODUCTS OF THE AQUACULTURE AND FISHERY INDUSTRY.
