Iced Storage

Lipid damage of farmed spotted Babylon snail muscle stored in ice for 7 days was evaluated by determining changes of lipid composition, fatty acid composition, peroxide value (PV), and p-anisidine value (p-AV). During 7-day iced storage, triglyceride, and phospholipids contents decreased but free fatty acid increased with storage time (p ≤ 0.05). Changes in saturated and polyunsaturated fatty acid were observed at extended storage time (p ≤ 0.05). No changes in PV and p-AV of snail muscle were found during the first 4-day iced storage (p > 0.05). However, PV and p-AV of snail lipid increased during 4-day and 7-day iced storage (p ≤ 0.05). Rancid odor assessment of snail muscle exhibited a significant increase in rancidity (p ≤ 0.05) after 3 days of storage. Bacteria counts of snail muscle exceeded 7 log CFU/g, which was considered as the limit for acceptability after 7 days of iced storage. In conclusion, these results revealed that lipid damaged by hydrolysis and oxidation occurred in snail muscle during iced storage.

A large quantity of triglyceride was detected histochemically in nutrient-deposit cells of the trophosome in the beard worm (Oligobrachia mashikoi). The lipid extracted from the trophosome was composed of triglyceride, several kinds of phospholipid, free fatty acid, cholesterol, and cholesterol ester. The fatty acid of the triglyceride was comprised mainly of a monoenoic type, such as palmitoleic acid (16:1) and oleic acid (18:1), which accounted for 31% and 37% of the total fatty acids, respectively. In addition, in blood triglyceride, the fatty acid composition was almost the same.

This report from Golembeski and Emery adds to the small quantity of literature in this field. Drs Golembeski and Emery claim that they are presenting information that counters our statement,"The abnormalities in fatty acid composition of the cystic fibrosis milk may contraindicate its use for the nursing infant." However, no data regarding fatty acid composition were presented. In their Table, only total lipids are shown. In our study, we acknowledged that mean total lipids were sufficient to supply the energy needs of the nursing infant.

The sensitivity of Listeria monocytogenes Scott A and ATCC 19114 to antimicrobial compounds was altered when bacterial membrane lipid composition was modified by growth in the presence of added fatty acids. Analysis of cellular fatty acid composition by gas-liquid chromatography indicated that L. monocytogenes Scott A cells contained 0.97, 2.32, 0.81, and 0.72% (relative) of C14:0, C16:0, C18:0, and C18:l, respectively. In the presence of exogenously supplied C14:0, C16:0, C18:0, and C18:l, the percentages increased to 14.03, 30.92, 16.30, and 27.90%. Average MICs for L. monocytogenes Scott A and ATCC 19114 to sodium chloride, tertiary butylhydroquinone, methyl paraben, and propyl paraben were 10.0%, 81, 1406, and 544 μg/ml, respectively. Growing either strain in the presence of 50 μg/ml of either exogenously added C14:0 or C18:0 fatty acids increased their resistance to the four antimicrobial compounds. However, growth in the presence of C18:1 led to increased sensitivity to the antimicrobial agents. The results indicate that the susceptibility of L. monocytogenes to antimicrobial agents is related to the lipid composition of the cell membrane. Consequently, food preservation processes which alter fatty acid composition of L. monocytogenes could result in changes in antimicrobial susceptibility.
