ATP-bioluminescence assay was used to evaluate the cleaning and sanitizing procedures of stainless steel milk contact surfaces. Surfaces of a raw milk transportation tank, a raw milk cooling storage tank, an equalization pasteurizing tank, a pasteurized milk storage tank and a pasteurized milk packaging tank, as well as a milk centrifuge were evaluated. The Relative Light Unit (RLU) using a com...

Background and Objectives: Pre-requisite programs (PRPs) are “primary conditions and requirements essential for HACCP operations, which are crucial in food safety programs”. The present study was conducted to evaluate the impact of implementation of PRPs on the microbial parameters of pasteurized milk (according to the National Standard of Iran). Effectiveness of HACCP operation req...

Model Cheddar cheeses were prepared from pasteurized milk artificially contaminated with high 10(4) to 10(5) CFU/ml) and low (10(1) to 10(2) CFU/ml) inocula of three different Mycobacterium paratuberculosis strains. A reference strain, NCTC 8578, and two strains (806PSS and 796PSS) previously isolated from pasteurized milk for retail sale were investigated in this study. The manufactured Chedda...

There is little doubt that raw milk is the most scrutinized agricultural commodity. Appendix N of the Pasteurized Milk Ordinance requires that all bulk tank milk be tested for beta-lactam antibiotics. This document also sets the regulatory levels for somatic cell counts (SCC) and bacteria levels in raw bulk tank milk. Milk processors are required to perform the regulatory testing. Many progress...

the use of bacteriocins, mainly nisin, is one of the most significant preservation technologies in the food industry. nisin encapsulation can improve stability and homogenous distribution in food matrices. in this study, liposomes of four various lipids (lipoid s 100, lipoid s pc-3, lipoid s pc, and lipoid pc (dppc)) were prepared by dehydration-rehydration method, and compared for entrapment e...

OBJECTIVE To compare an alternative method to the most probable number (MPN) test for the detection of total coliform present in manually expressed human milk. METHODS 343 samples of manually expressed human milk from flasks donated to the Human Milk Bank of Instituto Fernandes Figueira--IFF were sent to the Laboratory of Food Control of IFF. The samples were used for comparing both methods, ...

Certain types of goat's cheeses are produced using unpasteurized milk, which increases the food safety concerns for these types of products. Popularity and consumption of goat's milk products have increased, and the niche market includes gourmet goat's cheeses. The U.S. Code of Federal Regulations and the Pasteurized Milk Ordinance both address the possibility for processing alternatives to hea...

Bronchopulmonary dysplasia (BPD) is the most common complication after preterm birth. Pasteurized donor human milk (DHM) has increasingly become the standard of care for very preterm infants over the use of preterm formula (PF) if the mother's own milk (MOM) is unavailable. Studies have reported beneficial effects of DHM on BPD. We conducted a systematic review and meta-analysis of randomized c...

The most important products of the dairy industry are: pasteurized liquid milk, casein and products derived by casein, and whey protein concentrates. Among the different advanced processes developed for getting better quality products in comparison to those obtained with traditional technologies, the processes based on the use of dense carbon dioxide are preferable from many points of view. In ...

The objective of this study was to determine the effect of increased vitamin D fortification (250 IU/serving) of high-temperature, short-time (HTST)-processed 2% fat milk, UHT-processed 2% fat chocolate milk, and low-fat strawberry yogurt on the sensory characteristics and stability of vitamin D during processing and storage. Three replicates of HTST pasteurized 2% fat milk, UHT pasteurized 2% ...
