Efficient monitoring is an open problem in the operation of anaerobic digestion processes, due to lack accurate, low-cost, and proper sensors for on-line key process variables. This paper presents two approaches indirect cheese whey wastewater. First, observability property addressed using conventional nonconventional techniques, including index. Then, model-based observer extended Luenberger o...

From 1948 to 1988, there were 6 confirmed foodborne disease outbreaks in the U.S. transmitted with domestically produced hard cheeses as the food vehicle. Various research reports have raised concerns about the public health protection provided by the current 60-day aging period in the manufacture of hard cheeses made with unpasteurized milk. The objective of this study was to investigate the a...

Whey cheeses have been produced from the very early steps of cheesemaking practices as a sustainable way to utilize whey, which is main by-product cheesemaking. Traditional whey cheeses, manufactured with similar processes, are Ricotta, Ricotta salata or Ricottone, and fresca in Italy; Anthotyros, Myzithra, Manouri, Xynomyzithra, Urda Greece; Serbia Romania well other countries such Israel; Lor...

A study was conducted with a pilot-scale sterilization system based on 27-MHz radio frequency (RF) energy to investigate the effectiveness in shortening process time and in improving quality for foods sealed in 6pound military-ration polymeric trays. Chemical marker M-1 was used to evaluate heating uniformity in 20% whey protein gels as a model food, and macaroni and cheese was processed to ass...

Whey, a valuable by-product of cheese manufacture, is the liquid fraction drained from the curd. Recently, the biological properties of individual whey constituents, such as a-lactalbumin (a-La) and b-lactoglobulin (b-Lg), lactoperoxidase (LP), lactoferrin (LF), glycomacropeptide (GMP) and immunoglobulins (IgGs), have become a focus of commercial interest as potential ingredients of so-called f...

The production of value-added products could be a valuable option for cheese wastewater management. However, this kind of study cannot just focus alone on getting the final product. This also necessitates studies on the dynamics of bioprocesses. With these as background, the present investigation aimed at evaluating the buffering capacity of deproteinized whey and effect of temperature and nitr...

This work presented the results of the implementation of an off-line smoothing algorithm in the monitoring system, for the partial hydrolysis of cheese whey proteins using enzymes, which used penalized least squares. Different algorithms for on-line signals filtering used by the control were also compared: artificial neural networks, moving average and smoothing algorithm.

BACKGROUND This study aimed to estimate the effect of the season of milk production and the packaging method on sensory characteristics and some physicochemical indices of fresh curd cheese stored in cooling conditions. MATERIAL AND METHODS This study covered three seasons: autumn (October), winter (January) and spring (March/April). The experimental samples were vacuum packed in 50 or 100 μm...
