The present study was conducted to evaluate the effects of using raw or microwave irradiated safflower seed on dry matter intake, milk production and composition, milk fatty acid profile, blood parameters, and nutrient apparent digestibility in early lactation cows. Nine multiparous Holstein cows at early lactation were randomly assigned to one of three treatments based on 3 × 3 balanced latin ...

A lactose-hydrolyzed milk with low sweetness was developed using nanofiltration. Raw milk was treated with 0.03% β-galactosidase at 4°C for 24 h to hydrolyze lactose partially. The resultant lactose-hydrolyzed milk containing 0.43% lactose was then concentrated using a nanofiltration membrane to reach concentration factor of 2.13. The concentration factors and coefficients of retention of milk ...

Raw milk consumption in Italy has increased over the last few years and although raw milk is characterised by cold chain, short shelf-life and the duty of boiling before domestic consumption, it is still considered a hazard. From 2010 to 2013 a monitoring survey of raw milk sold through vending machines was carried out to investigate the occurrence of several foodborne pathogens stipulated in t...

Emerging economies have often poor hygiene practices in traditional milk and dairy production all over the world.

Escherichia coli and coliforms are often used as indicator microorganisms, so their presence in food implies poor hygiene and sanitary practices. The...

BACKGROUND:Due to the large proportion of iodine present in milk and dairy products, they have been one of the important sources of nutritional iodine in several countries. Information about variation in milk iodine concentration in Iran is limited. OBJECTIVES:The present study was conducted to determine the iodine concentration in Iranian milk and dairy ...

This study describes a multiplex PCR assay developed for the detection of Staphylococcus aureus enterotoxin types: SEA, SEB, SEC, SED, and SEE presented in the literature as classical. The method was then used to analyse the presence of genes encoding these enterotoxins in .S aureus strains isolated from raw milk. A total of 237 raw milk samples were used in the study and 77 (32.5%) of them wer...

Yersinia enterocolitica is a common food-borne pathogen involved in yersiniosis among humans. The present study aimed to isolate virulent Y. enterocolitica from small ruminant milk in Shahrekord, Iran. One hundred raw milk samples of 84 sheep and 16 goats were collected from different parts of Shahrekord, during fall 2015. The samples were studied by microbial method and the positive-culture sa...

milk and milk products containing antibiotics especially penicillin may present a health hazard to individuals who are super sensitized to penicillin. a total of 620 samples of raw milk which were delivered to tehran pasteurization plant were examined. 294 samples were antibiotic-negative and 326 samples showed to contain antibiotic. considering the results obtained, certain recommendations wer...
