The objective was to evaluate the effect of beta-lactoglobulin (beta-lg) polymorphism and seasonality on milk composition (fat, lactose, total solids, milk urea nitrogen, total protein, true protein, casein and somatic cell counts) of Holstein and Girolando cows. Milk and blood samples from 278 Holsteins cows and 156 Girolando cows were taken during two dry seasons and two rainy seasons, for mi...

Background Atopic dermatitis is a multifactorial disease associated with elevated production of IgE and sensitization to multiple food and inhalant allergens.The aim of this study was to assess the levels of total serum IgE (IgE) and specific IgE (sp IgE ) for Dermatophagoides pteronyssinus (Dp), Blomia tropicalis (Bt), egg white, casein, alpha-lactalbumin and beta-lactoglobulin in patients wit...

OBJECTIVE Little is known about cow's milk protein intolerance (CMPI) in India. This study was aimed at finding CMPI cases and determining the role of IgG anti-beta-lactoglobulin antibody in the diagnosis of this condition in India. METHODS From June 2004 to December 2005, 30 children with presumptive diagnosis of CMPI, based on endoscopic rectal or duodenal biopsy showing excess eosinophils ...

Plasticizer effect on oxygen permeability (OP) of beta-lactoglobulin (beta-Lg) films was studied. Propylene glycol (PG), glycerol (Gly), sorbitol (Sor), sucrose (Suc), and polyethylene glycol at MW 200 and 400 (PEG 200 and PEG 400, respectively) were studied due to their differences in composition, shape, and size. Suc-plasticized beta-Lg films gave the best oxygen barrier (OP < 0.05 cm3 x micr...

cow’s milk allergy is one of the most common food allergies in childhood. beta- lactoglobulin (β-  lg) is  a dominant  allergen in  cow’s milk. hydrolysis is  known as  an effective method to reduce the allergenicity of proteins. thus, the objective of this study was to compare the allergenicity of β-lg and its hydrolysates using an animal model. twenty four balb/c mice were divided into three ...
