Abstract:
Five different vegetable oils were used in the production of fresh cheese to increase the concentration of polyunsaturated fatty acids (PUFAs), particularly α-linolenic acid (ALA), the most important omega-3 fatty acid of vegetable origin. Physico-chemical and microbiological characteristics of functionalized cheeses were evaluated after 1 and 3 days of ripening at 4 °C while the consumer appreciation was evaluated in the final product at 3 days of ripening. After 3 days, the cheeses with Camelina sativa and Echium plantagineum oils added exhibited the highest retention of PUFAs (mostly ALA) compared to those with flaxseed, raspberry and blackcurrant oils. The addition of oil showed little effects on physico-chemical characteristics and also consumers' evaluation highlighted that all of the fresh cheeses were considered acceptable although those with flaxseed and raspberry oils were the most appreciated.

Mechanical and Chemical Digestion in the Small Intestine
Mechanical digestion in the small intestine involves movements such as segmentations and migrating motility complexes (MMCs), primarily controlled by the myenteric plexus. Segmentations are localized contractions occurring in areas of the intestine distended by chyme—a mixture of partially digested food. These contractions mix chyme with digestive juices, facilitating...

Overview of Fatty Acid Metabolism
Fatty acids are catabolized in a process called beta-oxidation, which takes place in the matrix of the mitochondria and converts their fatty acid chains into two-carbon units of acetyl groups. The acetyl...
