Successful Stories in Food Science in Spain

1.) Prof. Diego García-Gonzalo

This interview was recorded in 2011 at the University of Zaragoza in Zaragoza, Spain.

Candy

Candy is a confection made from a concentrated solution of sugar in water, to which flavourings and colorants are added. Other ingredients can be added like milk, to obtain caramel, or gelatins or other thickeners to obtain marshmallows or gummies. Candy Technology uses scientific knowledge drawn from chemistry, physics or material science to produce one of the world’s favourite treats.

Nanotechnology in Food

Nanotechnology is the study and application of materials at the nano scale. A nanometer is 0.0000000001 of a meter. Over the past few years, the development of nanosciences and nanotechnology has brought news perspectives for many industry and consumer sectors.

 

High Hydrostatic Pressure

The application of high isostatic pressures enables food processors to produce high quality fresh food with an extended shelf-life, without the application of heat or the use of chemical preservatives.

 

Drying

Drying of foods is one of the most common process used for food preservation. Drying is based on the removal of water from a moist material so it decreases the water activity of the material. Therefore drying reduces microbiological activity and minimizes the risk of physical and chemical changes during its storage.

Genetic modified organisms

Genetic modified organisms or genetically modified organisms (GMO) are, as you may have gathered by the name, organisms whose genetic material have been altered using genetic engineering techniques instead of traditional crossbreeding where these experimental combination of genes cannot occur.
