Agricultural and Biosystems Engineering Conference Proceedings and Presentations

In the industry, expelling and hexane extraction are the two typical processes for soybean oil production. However, the low efficiency and hazardous chemical problem are the main issues for these two processes respectively. Enzyme assisted aqueous extraction process (EAEP) is applied to increase the efficiency without using organic solvent, which is replaced by water. The environmental impact analysis of these three processes are based on their mass flows, energy consumption and global warming potential. For mass flows, the environmental impact indices were calculated based on mass balance of input and output components. Energy consumption was used to evaluate the carbon ...


Antioxidant Peptides In Commercial Dry-Cured Hams, Chao-Zhi Zhu, Joseph G. Sebranek, Dong U. Ahn 2016 Nanjing Agricultural University

Antioxidant Peptides In Commercial Dry-Cured Hams, Chao-Zhi Zhu, Joseph G. Sebranek, Dong U. Ahn

Animal Industry Report

Measurement of the antioxidant peptide content of six commercial dry-cured hams each from a different processor showed a wide range of peptide concentrations and antioxidant activity, but no clear association with processing variables such as drying and aging time, smoke application or cooking treatments. Thus, while the dry-curing process for hams has potential to result in significant production of antioxidant peptides, specific processing conditions considered in this study do not appear to affect production of these peptides.
