Supercritical CO2 extraction in chia oils production: impact of process duration and co-solvent addition

This study was conducted to show impact of supercritical fluid extraction using pure SC-CO2 or SC-CO2 enriched by 2, 6, and 10% of acetone, simultaneously varied by the extraction time (1 vs. 5 h), on the quality of chia seed oils. Obtained oils were relatively similar in the fatty acid composition, but they differed in total content of phytochemicals (from 4956 to 6391 mg/kg of...

Transfer of Listeria monocytogenes between abiotic surfaces under different weights

Cross contamination of Listeria monocytogenes from two different surfaces (plastic wrappers and stainless steel coupons) was simulated using a series of different weights. Enumeration of transfer was based on surface bacterial counts of biofilm stained surfaces. Direct contact between 2 surfaces has a constant rate of transfer that is independent of the pressure applied. This is...

Molecular cloning and anti-fungal effect of endo-β-1,3-glucanase from Thermotoga maritima

A gene encoding an endo-β-1,3-glucanase from Thermotoga maritima MSB8 (TmβG) was cloned and expressed in Escherichia coli. The purified enzyme produced various β-1,3-glucooligosaccharides from soluble laminarin, and mainly β-1,3-glucooligosaccharides smaller than laminaritetrose from insoluble curdlan. The optimum pH and temperature of the enzyme were 5.0 and 80°C, respectively...

Physical properties and antimicrobial activities of a persimmon peel/red algae composite film containing grapefruit seed extract

As a by-product of dried persimmon production, persimmon peel (PP) can be utilized as an edible film base material. In this study, PP/red algae (RA) composite films were prepared, and their physical properties were determined. Among the PP composite films, the 4% PP/1% RA composite film had the best physical properties (7.31 MPa, 8.16%, and 4.99 ng m/m2s Pa for tensile strength...

Two novel glycosyl cinnamic and benzoic acids from korean black raspberry (Rubus coreanus) wine

Korean black raspberry (Rubus coreanus) wine was solvent-fractionated with n-hexane, ethyl acetate, and n-butanol and the n-butanol layer was purified by various column chromatographic procedures, including Amberlite XAD-2, Sephadex LH-20, and octadecylsilane resins as well as high performance liquid chromatography. Two novel glycosyl cinnamic and benzoic acids were isolated and...
