Covalent Immobilization Of Lysozyme On Ethylene Vinyl Alcohol Films For Nonmigrating Antimicrobial Packaging Applications, V. Muriel-Galet, Joey N. Talbert, P. Hernandez-Munoz, R. Gavara, J. M. Goddard

The objective of this study was to develop a new antimicrobial film, in which lysozyme was covalently attached onto two different ethylene vinyl alcohol copolymers (EVOH 29 and EVOH 44). The EVOH surface was modified with UV irradiation treatment to generate carboxylic acid groups, and lysozyme was covalently attached to the functionalized polymer surface. Surface characterization of control and modified films was performed using attenuated total reflectance Fourier transform infrared spectroscopy (ATR-FTIR) and dye assay. The value of protein loading after attachment on the surface was 8.49 μg protein/cm2 and 5.74 μg protein/cm2 for EVOH 29 and EVOH 44, respectively, …

A system and method capable of hydrolyzing lactose, where the system includes a support formed from a functionalized hydrophobic polymer that is covalently linked to a hydrophilic molecule covalently that is, in turn, covalently linked to an enzyme such as lactose. The method includes the steps of functionalizing a hydrophobic polymer support, covalently linking a hydrophilic molecule to said functionalized polymer support, and covalently linking an enzyme such as lactase to said hydrophilic molecule. The system and method generally relate to the field of food science and engineering and, more particularly to dairy-based food products and their production including solutions …
Phaseolus Beans: Impact On Glycaemic Response And Chronic Disease Risk In Human Subjects, Andrea M. Hutchins, Donna M. Winham, Sharon V. Thompson
Phaseolus Beans: Impact On Glycaemic Response And Chronic Disease Risk In Human Subjects, Andrea M. Hutchins, Donna M. Winham, Sharon V. Thompson

Consumption of Phaseolus vulgaris bean species such as pinto, black, navy or kidney may be beneficial in the prevention and treatment of chronic diseases. In particular, conditions that are promoted by increased glycaemic stress (hyperglycaemia and hyperinsulinaemia) including diabetes, CVD and cancer seem to be reduced in individuals who eat more of these beans. The present paper discusses the influence of P. vulgaris species on glycaemic response and the impact that relationship may have on the risk of developing diabetes, CVD and cancer.

Background: African Americans have higher rates of cardiovascular disease (CVD) mortality than other ethnic groups. Young adults are prime targets for intervention strategies to prevent and reduce disease risk. The study purpose was to determine the level of knowledge of lifestyle risk factors for CVD among young African American adults in Phoenix. The results will be used to guide the development of CVD outreach programs targeted to this population. The Health Belief Model was used as a conceptual framework. Methods: A convenience sample of 172 African American men and women aged 18-26 years completed a questionnaire adapted from the American …

High hydrostatic pressure (HHP) at 500 MPa and 50 °C induces β-LG into the molten globule state. Retinol, cis-parinaric acid (CPA), and 1-anilino-naphthalene-8-sulfonate (ANS) fluorescence from pH 2.5 to 10.5 in the presence of the native and molten globule states of β-LG indicate that retinol binds to β-LG in the calyx, CPA at the surface hydrophobic site, and ANS in multiple hydrophobic sites. HHP treatment results in a decrease of β-LG affinity for retinol and CPA, suggesting conformational changes in the calyx and surface hydrophobic site of β-LG during HHP treatment. β-LG treated by HHP in the presence of N-ethylmaleimide …

Beta-lactoglobulin (beta-LG) was treated with high hydrostatic pressure (HHP) at 600 MPa and 50 degrees C for selected times as long as 64 min. The intrinsic tryptophan fluorescence of beta-LG indicated that HHP treatment conditions induced a conformational change. HHP treatment conditions also promote a 3-fold increase in the extrinsic fluorescence of 1-anilinonaphthalene-8-sulfonate and a 2.6-fold decrease for cis-paraneric acid, suggesting an increase in accessible aromatic hydrophobicity and a decrease in aliphatic hydrophobicity. Far-ultraviolet circular dichroism (CD) spectra reveal that the secondary structure of beta-LG converts from native beta-sheets to non-native alpha-helices following HHP treatment, whereas near-ultraviolet CD spectra reveal …
