New research from California confirms the safety of pasteurized mother’s milk for HIV-exposed babies (Israel-Ballard, 2005). Two methods of heat-treatment, known as Flash-Heating and Pretoria Pasteurization, were compared to assess their impact on HIV and antimicrobial properties of breast milk, as well as on nutrient content.Milk samples were spiked with clade C HIV-1 (the sub-type found in ar...

Th e aim of this study was to analyze the chemical composition of apple purees of four diff erent apple varieties: ‘Golden Delicious’, ‘Idared’, ‘Jonagold’ and ‘Cripps Pink’, in the fresh state (FP) and aft er thermal treatment by process of pasteurization with added green (PG) or white stevia powder (PW) derived from the leaves of the stevia plant. Also, to determine whether there is a signifi...

this study aimed to examine the effectiveness of combined microwave-ultrasonic pasteurization system on escherichia coli and vitamin c content in sour cherry juice (scj). based on the findings, microwave output power, ultrasound power, and ultrasonic exposure time as well as the microwave-induced temperature were the most effective factors in reducing e. coli and vitamin c content. in addition,...

contamination sites of pseudomonas fluorescenswere traced in the production line for milk pasteurization in a large dairy plant in shiraz, iran. samples of raw and pasteurized milk were collected at six sites along the line. all milk samples were incubated at 7°c until the aerobic plate count had reached 10 6 -10 7 cfu ml-1. colonies were picked randomly and identified. no growth of gram negati...

Sodium salt of N-acetyl-DL-tryptophan (AT) and octanoic acid (caprylic acid CA) individually and in combination were studied as thermal stabilizer with different concentrations in heat treatment of human albumin solution. HPLC protein profiles before pasteurization of albumin showed less than 1% polymer. In free stabilizer albumin solution during pasteurization visible clot was formed. But by u...

D URING the investigation of a recent epidemic of septic sore throat' the writers of this article ook occasion to make a fairly extensive .urvey of the literature of the strepto:occi with special reference to their relaion to the spread of disease through milk. Che results of this survey, together with :ertain observations made in the course of he investigation, have impressed us with he fact t...

Loss of ordered molecular structure in proteins is known to increase their adhesion to surfaces. The aim of this work was to study the stability of norovirus secondary and tertiary structures and its implications for viral adhesion to fresh foods and agrifood surfaces. The pH, ionic strength, and temperature conditions studied correspond to those prevalent in the principal vehicles of viral tra...
