Basic Information


The course is based on the study of food conservation and cooking techniques, including the techniques used at an industrial level and that will help the student to acquire the theoretical-scientific foundations on which the different techniques are based, which will allow them to improve the skills in the exercise of their profession, improving both the quality and safety of processed foods. The contents include basic contents of food microbiology, preservation techniques by cold, heat, drying and dehydration, as well as in protective vacuum, modified and controlled atmospheres. In addition, it includes culinary techniques for preserving and preparing food from the traditional to the avant-garde, with special emphasis on the vacuum technique.  

The vacuum technique has been an effective way of preserving for years, but over the years and thanks to research, we have not only discovered a great way to control culinary processes, but also an exceptional system to comply with hygienic regulations. current health. 

Mastering all these techniques allows us to extend best-before dates, control shrinkage and stocking, and greatly facilitate catering services thanks to the controlled regeneration of food that has been prepared in a production kitchen. All of this enables costs to be controlled and helps to make purchases and orders, facilitating organization in warehouses. 

The course also includes notions about the hygienic-sanitary standards that must be complied with in the hotel industry, which will help us, together with the knowledge about the different preparation and conservation techniques, to improve the safety of food throughout its useful life, avoiding the development and proliferation of bacteria, as well as the toxic content of processing, offering customers a service of the highest quality. All this will allow improving the management of a gastronomic business, even allowing the optimization of the work of the staff and the standardization of processes.  

An extensive knowledge of the vacuum technique also allows the production of fifth-range products, giving the possibility of creating an own brand and avoiding having to acquire this type of food through third parties, reducing costs. In addition, it should be noted that Aranjuez has an exceptional raw material with which students will be able to apply this innovative culinary technique in a practical way in the development of menus.


Master all the concepts derived from food preservation and preparation techniques used both at an industrial and culinary level, from the traditional to the avant-garde, with special emphasis on the use of the vacuum theory in its two aspects of preservation and cooking of food.
