The Effects Of Sous Vide Cooking And Cysteine Proteases On Instrumental And Sensory Textural Properties Of Lower Value Cuts Of Beef, Ian Smith

All Theses

Sous vide cooking has the potential to increase the value of lower quality cuts of beef. Understanding the textural properties following a cook-chill sous vide process is crucial to maximizing this potential. The use of enzymes may further increase the value of these products if able to positively alter the texture of the final product.

The first research objective was to use instrumental texture analysis to evaluate potential relationships between enzymatic treatments and sous vide processing time of lower value cuts of beef. Three cuts were evaluated: infraspinatus (top blade), semitendinosus (eye of round), and beef tongue. Infraspinatus and semitendinosus …

Effect Of Forage Type And Corn Supplementation On Animal Performance And Meat Quality, Asher Wright

All Theses

Angus x Hereford steers (441 ± 24 kg; n = 32) were used in a 2-yr study (2011 and 2012) to examine forage type (legume species, alfalfa and soybeans LG vs. grass species, tall fescue and sudangrass, GR) and daily corn supplementation (0%, NS, vs. 0.75% BW, CS) on animal performance and carcass quality. Steers grazed (May-August) for a total of 98 d and 105 d in 2011 and 2012 respectively. Upon completion of the finishing period, steers were slaughtered and carcass data were collected. Steaks (2.5 cm thick) from the longissimus dorsi muscle (LM) were collected for measurement of …
