The digestive process transforms nutrients and bioactive compounds contained in food to physiologically active compounds. In vitro digestion systems have proven to be powerful tools for understanding and monitoring the complex transformation processes that take place during digestion. Moreover, the investigation of the physiological effects of certain nutrients demands an in vitro digestive pro...

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...

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...

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% ...

A simple, precise, accurate, and validated reverse-phase HPLC method was developed for the determination of melamine in milk (pasteurized and UHT milk) and dairy products (powdered infant formula, fruit yogurt, soft cheese, and milk powder). Following extraction with acetonitrile:water (50:50, vol/vol), samples were purified by filter (0.45 μm), separated on a Nucleosil C8 column (4.6 mm × 250 ...

The organoleptic quality and stability of pasteurized milk are closely related to consumption choices. Our study investigated the effects different homogenization pressures on during shelf life. three used in this work were 0, 150, 300 bar. times 40 s, 56 60 s respectively. sensory after storage for 8, 72, 168 h by description experiment, electronic nose technology, physical properties (such as...

Although a causal link between Mycobacterium avium subspecies paratuberculosis (MAP) and Crohn's disease has not been proved, previous studies suggest that the potential routes of human exposure to MAP should be investigated. We conducted a systematic review of literature concerning the likelihood of contamination of food products with MAP and the likely changes in the quantity of MAP in dairy ...
