ABSTRACT Roasts were heat processed by infrared and convection to compare the effects of these alternate heating methods upon nutrient retention. In addition to proximate analyses, nutrients analyzed included: thiamin, riboflavin, seven fatty acids, 18 amino acids, ammonia, sodium, phosphorus and iron. Convective heating of turkey breast and corned beef produced a higher product yield. Few significant differences between heat processed samples were revealed. After convection heating of corned beef, riboflavin was significantly higher (P < 0.05) than after infrared heating. Similarly, arachidonic acid (C20:4) was higher in turkey breasts. After infrared heating of pork, aspartic acid, threonine, serine were lower than after convective heating; ammonia was higher.
