Factors Affecting Separation of Low Fat Flesh from Fatty Fish by Cryo‐shattering

摘要

ABSTRACTOur previous report on separating low fat flesh from fatty fish by cryo‐shattering indicated that at appropriate temperatures, fat content in particles increased with particle size. The effect was temperature dependent; that effect of low temperature on fracture stress and elastic modulus of model fish flesh was further examined at ‐ 60°C to ‐ 196°C. The fish flesh showed abrupt changes in compression and tensile fracture stress at about ‐ 90°C and ‐ 150°C; such changes strongly affected fat content‐particle size relations (FCPSR). Using measured fracture stress and elastic modulus values, FCPSR was successfully simulated when Bond's equation was linked with an empirical equation to estimate wo
