Industry throughout the world is faced with a common problem that of the disposal of waste materials from manufacturing processes. In the case of the dairy industry, one such 'waste' which is produced in enormous quantities is the whey resulting from cheese and casein manufacture. In the 1996/97 season alone it is estimated that around five billion litres of whey were produced in New Zealand. I...

background and objective : mozzarella is a soft cheese belonging to the pasta filata family, containing 18-24 % fat. the objective of this study was to determine the effect lowering mozarella fat content to 6% and adding whey protein concentrate on the rheological properties of the low-fat cheese. materials and methods : low-fat mozzarella was produced using 3 fat replacers ( dairy-lo, 35% prot...

Supercritical Water Gasification is a promising approach to convert biogenic residues such as cattle manure, fruit/vegetable waste, and cheese whey into valuable biofuels.

Annatto is a yellow/orange colorant that is widely used in the food industry, particularly in the dairy industry. Annatto, consisting of the carotenoids bixin and norbixin, is most commonly added to produce orange cheese, such as Cheddar, to achieve a consistent color over seasonal changes. This colorant is not all retained in the cheese, and thus a percentage remains in the whey, which is high...

Milk processing industries and distributors have problems with adulteration of liquid milk by the addition of bovine cheese whey. Recently, the detection of fraudulent manipulation of milk with whey has focused on the identification of glycomacropeptide (GMP). Current non-immunological methods to detect GMP in dairy products are expensive and time-consuming or have low sensitivity. In this stud...

The milk whey remaining at the end of cheese-making process is main by-product dairy industries and it currently used as a source high added-value compounds by food pharmaceutical industries. aim this research was to study effects season on residual characteristics in Parmigiano Reggiano process. Over two years, total 288 trials PDO (Protected Designation Origin) cheese were performed three com...

Cheese whey, the main dairy by-product, is increasingly recognized as a source of many bioactive valuable compounds. Nevertheless, the most abundant component in whey is lactose (ca. 5% w/v), which represents a significant environmental problem. Due to the large lactose surplus generated, its conversion to bio-ethanol has long been considered as a possible solution for whey bioremediation. In t...

A rapid and accurate method to identify bovine and ewe milk adulteration of fresh water buffalo mozzarella cheese by using matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOFMS) is described. The differentiation among mozzarella made from water buffalo milk and from mixtures of less expensive bovine and, more recently, ewe milk with water buffalo milk is achi...

The main aim of this work was to evaluate the efficiency producing caproic acid and other volatile fatty acids using a co-digestion between cheese whey sewage sludge in continuous reactor. effect two different feeding regimes (one per day) three hydraulic retention times (HRT) (15, 10 6 days) on organic production were studied. optimal conditions for process days HRT, 2 cycles day, reaching max...
