Nanoemulsions of β-carotene using a high-energy emulsification-evaporation tech...

Nanoemulsions of β-carotene were prepared using a high-energy emulsification-evaporation technique based on a 23 level factorial design. Results show that it is possible to obtain dispersions at a nanoscale range. Process parameters such as time and shear rate of homogenization affected significantly particle size distribution in terms of volume-weighted mean diameter and surface-weighted mean diameter. The obt...

Physico-chemical characterization of chitosan-based edible films incorporating ...

Chitosan packaging films containing different bioactive compounds (a peptide fraction from whey protein concentrate (WPC) hydrolysate, glycomacropeptide (GMP) and lactoferrin) were produced and their mechanical and barrier properties were evaluated. The molecular weight of protein-based compounds was determined using SDS–PAGE. The addition of GMP and lactoferrin to chitosan film caused a significant reduction o...

Shelf life extension of Ricotta cheese using coatings of galactomannans from no...

Shelf life extension of Ricotta cheese was evaluated at 4 °C upon the use of edible coatings made of galactomannans from Gleditsia triacanthos incorporating nisin against Listeria monocytogenes. Three different treatments were tested in cheese: samples without coating; samples with coating without nisin; and samples with coating containing 50 IU·g−1 of nisin. To test the effectiveness of the treatments against ...

Nano structures for food applications

Effect of the application of a galactomannan coating incorporating nisin on the...

Antimicrobial packaging, besides protecting the product from the external environment, inhibits or delays microorganism growth in foods and meets the actual demand of consumers for healthier foods, containing less additives (Lopez‐Rubio, Gavara, & Lagaron, 2006). Cheese is a ready‐to‐eat type of food that has been associated with foodborne listeriosis. Listeria monocytogenes is an important ubiquitous foodborne...

Differentiation of human pre-adipocytes by recombinant adiponectin

Obesity has become a global health problem and it is linked to a higher risk of diseases and metabolic disorders such as diabetes, cardiovascular disease, and cancer. The adipose tissue plays an important role in monitoring and controlling whole-body metabolism by secreting a variety of bioactive molecules such as adiponectin. Deficiencies of this hormone can cause type II diabetes and cardiovascular disease bo...
