UNLABELLED Human milk provides crucial nutrition and immunologic protection for infants. When a mother's own milk is unavailable, donated human milk, pasteurized to destroy bacteria and viruses, is a lifesaving replacement. Flash-heat pasteurization is a simple, low-cost, and commonly used method to make milk safe, but currently there is no system to monitor milk temperature, which challenges q...

Botulinum neurotoxin (BoNT) is the most toxic substance known to man and the causative agent of botulism. Due to its high toxicity and the availability of the producing organism Clostridium botulinum, BoNT is regarded as a potential biological warfare agent. Because of the mild pasteurization process, as well as rapid product distribution and consumption, the milk supply chain has long been con...

The Holder method is the recommended pasteurization method for human milk banks, as it ensures the microbiological safety of human milk (HM). The loss of some biologically active milk components, due to the heat treatment, is a main limit to the diffusion of donor HM. High-temperature short-time (HTST) pasteurization may be an alternative to maintain the nutritional and immunological quality of...

ABSTRACT The effects of non-thermal and low temperature treatments on parasite elimination and chemical and sensory quality of raw oysters were evaluated using: low temperature pasteurization, cold pasteurization, individual quick freezing, ultra-low freezing, and blast freezing. C. parvum was inactivated by all experiments. The results on the effect of treatments on C. cayetanensis were inconc...

Thermal Pasteurization of Eggs, as a widely used nutritive food, has been simulated. A three-dimensional numerical model, computational fluid dynamics codes of heat transfer equations using heat natural convection, and conduction mechanisms, based on finite element method, was developed to study the effect of air cell size and eggshell thickness. The model, confirmed by comparing experimental a...

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...

Thirty-one batchor continuous-flow milk pasteurizers used on commercial dairy and custom calf-feeding operations were surveyed. One sample of raw waste milk (RWM) immediately prior to onfarm pasteurization and one sample of pasteurized waste milk (PWM) immediately after on-farm pasteurization from daily waste milk pools were evaluated. The RWM and PWM samples were evaluated for nutrient composi...

To investigate how B. anthracis Sterne spores survive in milk under heat (80 degrees C, 10 min), pasteurization (72 degrees C, 15 s), microfiltration, and pasteurization and microfiltration, the expression levels of genes related to sporulation and germination were tested using real-time PCR assays. Twenty-seven sporulation- and germination-related genes were selected for the target genes. Our ...

The effect of cream pasteurization on the composition and microstructure of buttermilk after pasteurization, evaporation and spray­ drying was studied. The composition of milk fat globule membrane (MFGM) isolated from buttermilk samples was also characterized. Pasteurization of cream resulted in higher lipid recovery in the buttermilk. Spray-drying of buttermilk had a significant effect on phos...
