Molecular distillation of a crude soybean oil

Improvement in the Color of Peanut and Cottonseed Proteins

“…As the pigment concentration increases, there is a progressive shift to longer dominant wave lengths. This phenomenon was previously observed to occur at wave lengths longer than 570 millimicrons by Newhall and associates (IS) in the case of the Munsell colors and by Detwiler and associates (7) in the case of soybean oils containing varying concentrations of carotenoid pigments.…”

The influence of processing on the spectral properties of vegetable oils

“…Evans and Gillam (9) and Woodward (29) have shown that shifts accompanying changes in solvents do not exceed 7 m~. Detwiler et al (8) have pointed out that the positions of observed absorption maxima in the visible red spectra of soybean oil are in better agreement with the absorption of pheophytin A than with chlorophyll A.…”

Optimization of deacidification of low-calorie cocoa butter by molecular distillation

“…Especially, the separation and purification of this method are more efficient than the traditional methods and preserve the desirable components due to low pressure and low residence time (Batistella & Maciel, 1998;Chen et al, 2005;Martinello et al, 2007;Posada, Shi, Kakuda, & Xue, 2007;Shao, Jiang, & Ying, 2007). MD applications for removing FFAs from high acidity crude oils and fats have attracted great interest including corn oil (Rawlings, 1939), vegetable oil (Martins, Ito, Batistella, & Maciel, 2006), grape seed oil (Martinello et al, 2007), and crude soybean oil (Detwiler, Bull, & Wheeler, 1943). However, research on MD for deacidification of low-calorie CB is still less explored.…”
