Abstract
The objectives of this research was to evaluate if the effects of very fast hot water thawing method on the meat quality attributes of pork tenderloin steaks are influenced by anatomical location of steaks within the tenderloin. Thawing was performed using a hot water bath at 39°C for 7 ± 0.5 min. Frozen steaks were cut approximately 2.5 cm thick with their thickness measured and accounted for individually for each steak after cutting. Starting from the tail end, steaks were identified as being from either the anterior (A), middle (M) or posterior (P) portions of the tenderloins. Minor but significant differences in thawing, cooking, and texture attributes of the steaks from various anatomical locations within the tenderloins were observed. When adjusted for SV, medium parts of tenderloin exhibited highest thaw drip loss. Cooking yield was influenced by steak location only when adjusted for SV ratio and increased from the anterior to the posterior end of the tenderloin. Location within tenderloin also influenced steak tenderness measurements. Steaks from medium parts of tenderloin had higher WBSF values compared to anterior and posterior parts of the steaks. Color changes in thawed steaks due to either thawing treatment or steak location were minimal and not detectable visually.
