The effect of selected processing parameters on viscoelastic properties of model processed cheese spreads. In their study, they used 3 sources of rework at 20% of the final PCF: fresh rework (quickly frozen PCF emulsion right after manufacture), regular PCF slices from older processing runs, and overcooked process cheese mass to simulate process cheese that had undergone excessive processing (which they referred to as “hot melt”). A few years later, in the United States, the development of process cheese was brought about by J. L. Kraft in 1916, when he preserved natural cheese in cans by heating and mixing it in order to increase its shelf life. Effect of emulsifying salts and NaCl Numerous researchers have shown the inhibitory effect of phosphate‐based emulsifying salts on the growth of various microbes and their antibotulinal effects in PCS (Tanaka and others 1979, 1986; Eckner and others 1994; ter Steeg and others 1995; ter Steeg and Cuppers 1995; Loessner and others 1997). The use of emulsifying salts such as disodium phosphate and trisodium citrate in process cheese manufacture aids in improving the emulsification properties of caseins by displacing the calcium phosphate complexes in the insoluble calcium–paracaseinate phosphate network present in natural cheese (Ellinger 1972; Gupta and others 1984; Caric and others 1985). Strategies to develop healthier processed cheeses: Reduction of sodium and fat contents and use of prebiotics. Prediction of total protein and intact casein in cheddar cheese using a low-cost handheld short-wave near-infrared spectrometer. Rework “Rework” is a term used to describe process cheese produced in a manufacturing facility that cannot be sold for a variety of reasons. Jacqueline B.

Impact of Myrrh Essential Oil as a Highly Effective Antimicrobial Agent in Processed Cheese Spreads. A significant portion of process cheese research remains as trade secrets within the industry and, consequently, has not been published. The levels of dairy‐based ingredients other than natural cheese used in PC are specifically defined by the CFR (Table 1). They found that as the final pH of the process cheese increased from 5.0 to 6.2, its firmness initially increased up to approximately pH 5.8 (where it had the highest firmness); however, with a further increase in pH (5.8 to 6.2), the firmness began to decrease. There have been various studies using different model systems to answer these questions (Cavalier‐Salou and Cheftel 1991; Guinee and others 2004; Mizuno and Lucey 2005). During the manufacture of natural cheese, rennet is used to cleave κ‐casein at the Phe105 and Met106 position, thereby dislodging the glycosylated hydrophilic region (glycomacro peptide). Ability to maintain identity when shredded for preparing shredded cheese for retail and other food preparations. They further indicated that use of alkaline extracts of annatto in process cheese showed a higher propensity to cause pink discoloration in process cheese. Acharya and Mistry (2005) manufactured PC using 5 different cheddar cheese treatments that were manufactured from cheese milk concentrated with different concentration techniques at different levels. Least cost formulation simply utilizes the cost and composition of an ingredient as a criterion for developing a formulation. Hence, there is a focus on the capacity of whey protein particles/aggregates to interact and form larger particles or a network in the processed cheese environment at typical cooking temperatures (80–100°C) during manufacture or later at the point of food service. As discussed previously, natural cheese has a marked influence on total calcium, intact casein, and pH and, hence, the final functional properties of process cheese. Trisodium citrate has been found to be less effective than disodium phosphate in preventing bacterial spoilage in PCS (Tanaka and others 1979; ter Steeg and others 1995). The earliest method to measure process cheese melted texture was the Arnott Test (Arnott and others 1957). Natural cheeses require size reduction prior to their use in these applications. On another note, fluorescence spectroscopy has also been used to evaluate Maillard browning and oxidative stability of process cheese during storage (Christensen and others 2003). “Thumb print” test2. We found a significant effect of the mixing speed on the viscosity immediately after manufacture, on firmness, on flow properties, and on the meltability of the PCF at all natural cheese ripening and all trisodium citrate levels. Process cheese (243 million kg) was the leader in total supermarket cheese sales followed by cheddar (240 million kg) and mozzarella (120 million kg) (IDFA 2006). pH The final pH of a process cheese has been found to have a significant effect on the quality, microstructure, and the type of protein interactions in the resulting process cheese emulsion (Palmer and Sly 1943; Meyer 1973; Marchesseau and others 1997). When these natural cheeses were used to make PC, the hardness of PC increased and the melt and the flow properties of PC decreased, as the level of concentration of the cheese milk to manufacture the natural cheese increased (in both the concentration techniques). The melted cheese after the pizza bake is extended/pulled into a string vertically off the pizza using a fork and the length of stretch before the string breaks is evaluated.
