Activities

  • A1 – Definition of coatings formulations and adaptation of the industry processing line
  • A2 – Optimization of the edible coating’s application process at industrial level
  • A3 – Studies of the coatings influence on the chestnut’s characteristics during storage
  • A4 – Project dissemination and communication

    CoLAB MORE leads Activity 1, responsible for defining formulations for chestnut coatings and adapting the industrial processing line, participating in the tasks of optimizing the methodology and application conditions of coatings at an industrial level (Activity 2) and evaluating the influence of coatings in storage (Activity 3).
