PRIORITY: HU 83-2668 28 Jul 1983. DOCUMENT TYPE: Patent CA Section: 16 (Fermentation and Bioindustrial Chemistry) Section cross-reference(s): 17 Protectants against oxidn. and spoilage that form surface films on wine are developed. Thus, 10% K2S2O5, 4.5% stearin monoglyceride [31566-31-1] and stearin diglyceride [1323-83-7], 3% sorbitan monooleate [1338-43-8], and 82.5% paraffin oil were homogenized and then milled so that all solid particles were <10 mm in diam. The suspension formed stable 5-mm thick films on aq. surfaces.

Rapid determination of triglyceride polymers by exclusion chromatography

Rapid determination of triglyceride polymers by exclusion chromatography. I. Qualitative aspect. Perrin, J. L.; Redero, F.; Prevot, A. (Inst. Corps Gras, Pessac 33600, Fr.). Rev. Fr. Corps Gras, 31(3), 131-3 (French) 1984. CODEN: RFCGAE. ISSN: 0035-3000. DOCUMENT TYPE: Journal CA Section: 17 (Food and Feed Chemistry) High-performance gels (styrene-divinylbenzene copolymer) with pore diams. of 50 and 100 ? were used for rapid exclusion chromatog. anal. of sunflower oil subjected to 10 cycles of heating to 200°, then cooling (like frying oil). Columns were 300 mm long with an internal diam. of 7.7 mm, and THF (0.75 mL/min, inlet pressure 24 bars) was the mobile phase. The app. was equipped with a differential refractometer. Resoln. between polymers and monomers was incomplete with a pore diam. of 50 ?, whereas satisfactory resoln. between polymers and triglycerides was obtained with the 100 ? gel. The method was applied to the anal. of the polar and nonpolar fractions obtained by the method of G. Guhr and C. Waibel (1978). The polar fraction contained all of the polymers, the majority of the dimers, and all of the oxidized triglycerides; diglycerides interfered by forming a shoulder. Exclusion chromatog. could also be used for sepn. of tri- [555-43-1], di- [1323-83-7], and monostearin [31566-31-1] and stearic acid [57-11-4].
