Membrane fractions from seedlings of four soybean [Glycine max (L.) Merr.] lines were examined by radioimmunoassay and hemagglutination assay for the 120,000 dalton soybean lectin. Two of the lines (Sooty and T-102) are genotypically lele and lack buffer-soluble soybean lectin; the remaining two lines (Beeson and Harosoy 63) are Le and produce seeds that contain the lectin (Su et al. 1980 Bioch...

INTRODUCTION Soybean allergy is one of the most common food allergies especially among children. The Food Allergen Labeling and Consumer Protection Act (FALCPA) in the US requires the labeling of soy lecithin because it is derived from soybeans and may contain a number of IgE-binding proteins, possibly representing a source of hidden allergens. Here we describe a pediatric case of soy allergy m...

Chemiluminescence (CL) that appears during oxidation of lecithin and ascorbate has been studied. A simple system consisting only of purified lecithin, which has one double bond, and ascorbate as a physiological reductant with a low redox potential, was used. The CL spectrum of lecithin contain a strong band lying in the near infrared, and three bands at 20 900 cm-1, 17 700 cm-1 and 15 800 cm-1,...

Lecithins are widely used in the food industry as additives. In this regard, requirements for lecithins quality quite high, and development of rapid determination methods their indicators, including acid value, is an urgent task. The article presents research peculiarities vegetable chemical composition a method determining value using pulsed nuclear magnetic relaxation (NMR) method. It was fou...

The purpose of this research is to formulate and evaluate the suitability of pluronic lecithin organogels containing flurbiprofen for topical application. Four formulations were developed using flurbiprofen, lecithin, Pluronic F127, isopropyl palmitate, water, sorbic acid and potassium sorbate were coded as FL1, FL2, FL3 and FL4. All the formulations carried 30% w/w of lecithin phase and 70% w/...

Propofol is an anesthetic agent suspended in an emulsion system that includes egg yolk lecithin and soybean oil, because of which, there is concern about the use of propofol in patients allergic to these substances. We examined the association between propofol administration and incidence of adverse events in dogs with allergy to egg yolk lecithin and soybean oil. On the basis of the findings o...

Acoustic technology shows the capability of protein pellet homogenization from different tissue samples of soybean and rice in a manner comparable to the ordinary mortar/pestle method and far better than the vortex/ultrasonic method with respect to the resolution of the protein pattern through two-dimensional polyacrylamide gel electrophoresis (2D-PAGE). With acoustic technology, noncontact tis...

We have shown previously that ox and pig bile accelerate in vitro growth of Giardia lamblia. We have now investigated the possible mechanisms by which mammalian biles promote parasite growth. Growth effects of (a) ox, pig, guinea pig, and human biles, (b) pure bile salts, and (c) egg and soybean lecithins were studied in the presence of a lecithin-containing growth medium. Individually, dilute ...

Two hundred twenty-eight crossbred steers (304 kg) were used in a 125-d comparative slaughter trial to evaluate the influence of level and source of supplemental fats on their feeding value for feedlot cattle. Dietary treatments consisted of a steam-rolled, barley-based finishing diet containing 1) no supplemental fat; 2) 4% yellow grease (YG); 3) 4% blended animal-vegetable fat (BVF); 4) 8% YG...
