Course description:
The commercial success of a given cheese and its acceptability by consumers are critically dependent on its quality attributes. Cheese consumption, and thus the success of cheesemakers, is greatly governed by the profile of quality attributes manifested by a given cheese. Cheese quality attributes include: flavor, aroma, texture, appearance, functionality, composition, nutritional value, etc. Among the keys to success in cheesemaking is the ability of cheesemakers to design, introduce, modulate, and control the evolution and manifestation of desired quality attributes in a given cheese. Meeting the latter goal requires cheesemakers to acquire understanding and practices that draw on a broad array of disciplines. Among these are microbiology, chemistry, enzymology, biochemistry, physics, dairy science, technology, engineering, and many more. Perceived cheese quality, at the time of consumption, is determined and governed by the process history of the cheese. The latter spans from milk production and handling, through cheese-milk treatments, curd making, cheese aging, storage, and delivery. Designing cheese quality attributes is dependent first, on understanding what profile of cheese quality attributes are desired by consumers, and then, on wisely introducing and controlling the evolution and manifestation of the desired cheese quality attributes during cheese making and cheese aging.
Topics covered in this course:
Understanding cheese quality attributes
Quality and properties of raw milk and their impact on cheese quality attributes
Setting the physical stage – designing and constructing the curd
Introducing the desired microbiological populations and biochemical cascades that, collectively, govern the evolution of cheese quality attributes
The manifestation of the potential – the actual evolution of cheese quality attributes and how to control and modulate them
Introducing and controlling cheese flavor
Introducing and controlling cheese functionality
Introducing and controlling cheese texture and structure
The dynamic nature of cheese quality attributes
Assessing and quantifying cheese quality attributes
This remotely-instructed class will introduce and discuss the multitude of concepts, phenomena, mechanisms and practices that cheesemakers have to understand and implement in order to successfully design, introduce and control cheese quality attributes.
Who should attend?
The class is designed for cheese professionals with a basic understanding and knowledge in the concepts of dairy chemistry and microbiology as well as in the unit operations that are associated with cheesemaking and aging.

If all cheese has the same basic ingredients, how can there be a wide variety of flavors? What is “sharp”? How can cheese be sweet? Join Jess Perrie for this virtual class as she breaks down the key reactions of flavor chemistry, what influences these reactions, and how regional environments have developed the flavors of the iconic cheeses we know today.

The class is 90 minutes plus 30 minutes of Q&A and will be held via ZOOM. The link to join will be emailed to all participants the week of May 29.
