Milk component retention is not just a way to make dairy processing more sustainable and to provide consumers with a wider range of foods. It has to do with efficiency. Therefore, optimizing cheese yields is a matter of economic sustainability for the plant and can be achieved by retaining the milk components in the most efficient way in the finished product.
In the current complex scenario, characterized by high competition in the dairy market, more demanding consumers, and environmental and market challenges, measuring and maximizing yield efficiency becomes a must. Thus, predicting cheese yield is the most effective way to foretell costs, estimate the budget and define pricing. Moreover, it offers multiple advantage in terms of plant and process management.
The first practical consideration should be made on inputs (from raw milk, to cream and whey) and outputs (cream recovered from standardization, whey from processing operations, etc.) of the cheese making process: processors will immediately understand how the determination of mass balance is a complex operation.
The highest benefit from all milk components is achieved with maximized retention in dairy products, especially if we consider that, with respect to cheese yield, producers’ goals are in general:
During cheese processing, in addition to the effects of salt and moisture, some operations influence the retention of milk components in the finished product. Taking process parameters under control is critical, as deviation from the optimum may dramatically impair both success of the operations and cheese yield. Here some examples: careless cutting may lead to loss of fat and proteins in the whey and to fines; fast heating at early stages of curd cooking may generate a higher tendency to break up and release fat and protein in the whey; protein loss are caused by proteolytic cultures or coagulating enzymes before and after cutting.
To predict cheese yields, many formulas exist and can be used in different ways. As reported by Emmons and Modler (2010), formulas can be applied to predict cheese yield from new recipes, but to understand the yields in cheeses of different composition as well. Formulas can be useful to adjust the observed yield to a standardized one. They can be strategic tools to assess accuracy of analysis, measurements, sampling. They would be able to suggest that a problem exists rather than identifying the problem.
For effective prediction of cheese yield, experience is important as it allows to have a solid general understanding of the specific process, best guiding the prediction and interpretation of formula results.
