Beef tenderness is an important factor contributing to consumer eating satisfaction of beef products. Tenderness is dependent on several factors including: breed-type, postmortem age time, myofibrillar muscle protein degradation, and collagen content. During the past 30 years, numerous studies have indicated steaks from cattle with a greater percentage of Brahman genetics are tougher than steaks from Bos taurus cattle. The cause of tougher steaks is commonly attributed to Brahman cattle having a greater calpastatin activity which inhibits calpains, the enzymes responsible for myofibrillar protein degradation during the postmortem aging process. Some researchers have reported calpastatin activity was poorly correlated to …

Consumers typically have the opportunity to select steaks from a variety of marketing categories that relate to quality, price, and expected tenderness. Research on quantifying characteristics of strip steaks from different marketing programs available in self-serve retail display cases and establishing benchmark data for strip steak comparisons for future years is needed. The purpose of this study was to determine mechanical tenderness as well as physical and cooking characteristics of strip steaks purchased from self-serve display cases in grocery store outlets throughout the year.


Freezing Improves Instrumental Tenderness Of Strip Steaks Purchased At Retail Grocery Stores, A. M. Collins, J. A. Unruh, T. A. Houser, S. Stroda Jan 2016

When meat is frozen cell membranes can be damaged, which may lead to lower water holding capacity and higher cooking losses. Several researchers have indicated that freezingLongissimusmuscle (strip loin) steaks may lower Warner-Bratzler shear force, a measurement to objectively measure beef tenderness, compared with steaks not previously frozen. The objective of this study was to determine the effect of freezing on beef tenderness and cooking characteristics of strip steaks purchased from grocery store outlets.


Freezing Strip Loin And Top Round Steaks Improves Warner-Bratzler Shear Force, R. Mcewan, J. A. Unruh, T. A. Houser, T. G. O'Quinn, N. Bloedow, Christopher Vahl, S. Stroda Jan 2016

Postmortem aging of steaks is a common practice used to improve tenderness of beef steaks. The impact of proteolysis and improvement in tenderness due to aging varies among muscles. When designing research protocols, samples for Warner-Bratzler shear force (WBSF) are often frozen for later analysis because of convenience and time limitations. Freezing stops postmortem aging and allows for storage until meat can be cooked for WBSF and/or sensory analysis. However freezing meat may cause damage to cell membranes resulting in lower Warner-Bratzler shear force (improved mechanical tenderness), lower water holding capacity, and greater moisture loss during cooking. Several researchers have …
