The Effects of Processing on the Nutritional Benefits of Fruit: Grapes, Raisins, and Papaya
Each component of a food can serve a beneficial, neutral or harmful function within the food and after consumption. Changes that occur during food, digestive, or absorptive processing modify the human nutritional potential of a food by changing food components or interactions between food …

The Impact of Instrumentation Location and Reliability on the Performance of Operators Using an Ecological Interface for Process Control
… advocates displaying the higher-order relations and properties of a work domain so that adaptive operator problem solving is better supported for both normal and abnormal system conditions. Moreover, EID argues that this information should be represented through graphical visualizations. However, …

Variability in Starch Rheological and Thermal Properties From Commercial Corn Hybrids and Its Effect on Food Functional Properties
… in a sample set of commercial hybrids and then identify different hybrids to determine relationships between starch rheological characteristics and food characteristics. Fifty-nine commercial corn hybrids grown in the same year at the same location were wet milled using a 100g …

Evaluation of an Alkali Corn Wet Milling Process
… wet milling process saved 20% in equipment costs and 2% in total production costs. The return on investment for the alkali wet milling process was 17.8% compared to 14.1% for the SO$\sb2$ process.

Factors Affecting the Textural Properties of Pork
The D sire line had less fat depth and greater percent lean than the C line (P < 0.05). Barrows were fatter than gilts, as evident by more subcutaneous fat, lower percent lean, and more intramuscular fat (P < 0.05). Pork quality measurements were inconsistent over sire line, indicating no advantage …

Impact of Oxidized Corn Oil and Synthetic Antioxidant on Swine Performance, Antioxidant Status of Tissues, Pork Quality and Shelf Life Evaluation
… status of tissues, pork quality, shelf-life, and antioxidant activity of skeletal muscle of finishing pigs. The experimental design was a complete randomized block design (CRBD) in a factorial arrangement (2x2), with 2 levels of corn oil (fresh or oxidized corn oil) and 2 levels of antioxidant …

Phytase and 1(alpha)-Hydroxycholecalciferol: Their Role in Improving Nutrient Bioavailability in Chickens and Pigs
… In chicks fed vitamin D$\sb3$-adequate and P-deficient diets, supplemental 1$\alpha$-OH D$\sb3$ was unable to improve nonphytate-P utilization ($P<0.05$). In another assay, duodenal mucosal cells from chicks fed P-deficient diets, with or without supplemental 1$\alpha$-OH D$\sb3$, were …

Development of a Model System to Evaluate Ascorbic Acid Destruction at Various Time/microwave Power Levels
In conclusion, ascorbic acid retention and peroxidase destruction in all three vegetables was higher at longer times and higher power levels. Model developed to evaluate RAA preservation in broccoli was applicable to predict RAA preservation in green bean and asparagus. These findings are …

Analysis of Heated Chemically and Genetically Modified Lipids
This sample of PH-SBO is slightly more stable; however, the LL-SBO should provide an acceptable substitute for PH-SBO for pan-frying applications.

The Effect of Starch Microstructure on Glass Transition, Gelatinization, and the Elevation of the Gelatinization Temperature by Saccharides
The microstructure of starch and non-uniform distribution of water within starch granules affect how starch granules interact with water which in turn governs the magnitude, energy, and temperature of subsequent thermodynamic transitions.
