13. Energy utilization of by-products from the soybean oil industry by broiler chickens: acidulated soapstock, lecithin, glycerol and their mixture
Acidulated soy soapstock (ASS) and lecithin (LEC) are by-products from processing soy oil (SO) for human consumption, whereas glycerol (GLY) can be obtained through the transesterification of vegetable oils during the production of biodiesel. These are valuable by-products for poultry feeds that have been underutilized in many parts of the world. One study w

15. Physicochemical properties of lecithin-based nanoemulsions obtained by spontaneous emulsification or high-pressure homogenization
Nanoemulsions composed of a medium-chain triglyceride oil core stabilized by rapeseed or sunflower lecithins were prepared by spontaneous emulsification and high-pressure homogenization. These nanoemulsions are compared with formulations stabilized by egg lecithin. Nanoemulsions obtained by high-pressure homogenization display larger droplet size (230 to 440

16. Assessing the growth and recovery of Salmonella Enteritidis SE86 after sodium dichloroisocyanurate exposure
The objective of the present study was to assess the growth and the recovery of Salmonella (S.) Enteritidis SE86 in different diluents, culture media and using different plating methods after the exposure to 200 mg/kg sodium dichloroisocyanurate (NaDCC). Before and after NaDCC exposure, SE86 was cultured at 30 °C and 7 °C in the following diluents: Peptone

17. Effect of the addition of soy lecithin and Yucca schidigera extract on the properties of gelatin and glycerol based biodegradable films
Gelatin-based films containing soy lecithin or Yucca schidigera extract and glycerol as plasticizer were produced by casting and characterized for their mechanical properties, water vapor permeability (WVP), water solubility, opacity and morphology. The addition of glycerol reduced the tensile strength, with a difference of ~ 68% between the values for the m

18. Utilização da lecitina de soja para a refrigeração e criopreservação do sêmen de cães / Effect of soy lecithin on dog semen refrigeration and cryopreservation
Sabe-se que a criopreservação do sêmen provoca uma perda significativa na qualidade espermática. Apesar de diversos estudos visando à melhora na qualidade do sêmen pós-descongelamento, é de consenso geral que a gema de ovo apresenta uma significante capacidade em evitar as crio-injúrias. No entanto, a grande variação na sua composição, assim com

19. Inhibition of listeria monocytogenes in minas frescal cheese by free and nanovesicle-encapsulated nisin
The effectiveness of free and nanovesicle-encapsulated nisin to control Listeria monocytogenes in Minas Frescal cheese was investigated. Commercial nisin was encapsulated into liposomes of partially purified soy lecithin. Free (0.1 mg/mL and 0.25 mg/mL) and nanovesicle-encapsulated nisin (0.25 mg/mL) were applied onto the surface of cheese samples, and L. mo

20. Characterization of lyophilized liposomes produced with non-purified soy lecithin: a case study of casein hydrolysate microencapsulation
A commercial casein hydrolysate was microencapsulated in liposomes produced with non-purified soy lecithin, cryoprotected with two different disaccharides and lyophilized. The encapsulation efficiency of casein hydrolysate ranged from 30 to 40%. The powders were analyzed by differential scanning calorimetry (DSC), scanning electron micrography (SEM), infrare

21. Desenvolvimento, caracterização físico-química e avaliação farmacocinética de nanopartículas auto-organizadas de quitosana / Development, physico-chemical characterization and pharmacokinetic evaluation of self-assembly chitosan nanoparticules
Objectives: Nanoparticles (NP) are useful to modulate the pharmacokinetics (PK) of drugs. The aim of this study was to develop innovative self-assembly nanovesicles (NV) constituted of chitosan and lecithin with isopropyl myristate (IPM) as oil core, able to modify the PK plasma profile of clozapine (CZP) and valproic acid (VPA). Methods: The NV were obtaine

22. Influência de lecitina e PGPR no processo de microestruturação de chocolate amargo / Influence of lecithin and PGPR in the microstructuration process of dark chocolates
Chocolates são produtos compostos por uma fase lipídica com predominância de manteiga de cacau, e que contem liquor, açúcar emulsificantes e eventualmente leite em pó (ou derivados lácteos) e aromas. As características físicas dos chocolates como brilho, dureza, fusão a temperaturas da boca e estabilidade térmica são conseqüências da estrutura�

24. Preparação e caracterização de suspensões coloidais de nanocarreadores lipídicos contendo resveratrol destinados à administração cutânea
Solid lipid nanoparticles (SLN), nanoemulsions (NE), and microemulsions (ME) were prepared by the hot solvent diffusion method, using tristearin or castor oil as oily phase, and soy lecithin and Solutol HS 15 as surfactants. Mean particle sizes ranged from 20 to 215 nm and negative zeta potentials were obtained for all nanocarriers. A HPLC method used to det
