An improved extraction and HPLC method for the simultaneous extraction and quantitation of retinol, α-tocopherol, α-tocotrienol and β-carotene was developed to analyze commercial whole/semi-skim/skim samples of raw/pasteurized/UHT milk in transparent plastic/glass bottles and Tetra Brik containers. The sample preparation method required prior saponification at 40oC for 15 min followed by n-hexa...

Forty midlactation Holstein cows averaging 635 kg of body weight (SE = 8) were allotted at wk 25 of lactation to ten groups of four cows blocked for similar calving dates to determine the effects of formaldehyde treatment of flaxseed and sunflower seed on fatty acid composition of blood and milk, milk yield, feed intake, and apparent digestibility. Cows were fed a total mixed diet based on gras...

Purpose There is an apparent convention within both consequential and attributional life cycle assessment (LCA) to assume a 1:1 substitution ratio between functionally equivalent product systems. However, this convention may not be compatible with the purpose of consequential LCA, which is to model the actual consequences of the decision at hand. This paper explores the implications of the conv...

The antimicrobial properties of essential oils, terpineol, and orange oil, in particular, varied according to the type of bacteria tested. Terpineol and other terpeneless fractions of citrus oils appeared to have greater inhibitory effect on food-borne bacteria than the other citrus oils or derivatives. Gram-positive bacteria were, in general, more sensitive to essential oils than gram-negative...

The cholesterol content in cow milk is influenced by both genetic and environmental factors. Despite the fact that the main part of cholesterol contained in milk is synthesised endogenously, via process independent of the offered diet type, the chemical composition of feed (especially fat) affects the content of this sterol in cow milk (Precht, 2001). The content of cholesterol in cow milk is r...

Abstract As a widely consumed foodstuff, milk and dairy products are increasingly studied over the years. At present time, profiling is used as benchmark to assess properties of milk. Modern biomolecular mass spectrometers have become invaluable fully characterize composition. This review reports analysis its components using liquid chromatography coupled with spectrometry (LC–MS). LC–MS whole ...

OBJECTIVE To compare iron absorption from infant formula and iron-fortified cow's milk. METHODS Twenty-four weanling Wistar rats were maintained in metabolic cages during the whole experiment (10 days). On the first day, the animals were divided into three similar groups according to their weight, length, hematocrit and hemoglobin levels: 1) infant formula; 2) powdered whole cow's milk fortif...

This chapter describes market developments and medium-term projections for world dairy markets the period 2022-31. Projections cover consumption, production, trade prices milk, fresh products, butter, cheese, skim milk powder whole powder. The concludes with a discussion of key risks uncertainties which could have implications over next decade.
