The purpose of this study was to develop a commercially viable method for synthesis of conjugated linoleic acid (CLA) using the linoleic acid fraction obtained from six pork by-products (liver, lung, heart, stomach, small intestine, and large intestine). The workflow of CLA synthesis from each by-product was as follows: washing→crude fat extraction→fractionation into saturated and unsaturated fatty acids→repeat unsaturated fatty acid fractionation→CLA synthesis. -9, -11, and -10, -12 CLA was synthesized from pork by-products.

Article Synopsis
- The study aimed to assess how human digestion affects the effectiveness of antibiotics (tetracycline, ofloxacin, and penicillin) and the resistance levels of Staphylococcus aureus RN4220 and methicillin-resistant S. aureus (MRSA) to these drugs.
- A model simulating the human gastrointestinal tract was used to observe changes in antibiotic concentrations and bacteria resistance during digestion, revealing that antibiotic levels decreased significantly and resistance increased.
- The findings suggest that digestion alters both the efficacy of antibiotics and the resistance of certain bacteria, highlighting important factors in antibiotic treatment effectiveness within the human body.
