Opis predmeta

Student gets the basic knowledge needed to begin work in the field of postharvest technology of fruit crops. This knowledge can be later upgraded with professional experience in enterprises such as large cold stores, distributive centres and retail chains, etc.)

Vrsta predmeta

Opće kompetencije

Students will be competent to:
• Determinate of optimal harvest date
• Determinate of physiological disorders of fruit
• Evaluate the standard fruit quality
Students will get knowledge of basic postharvest technology of fruit, postharvest fruit treatments and fruit packaging systems.

Oblici nastave

  • Field work
    Field work includes trip to orchards during harvest, trip to storage and packinghouses to see different postharvest technologies used in fruit crops.
  • Laboratory practice/exercises
    In Laboratory students will learn about basic parameters used to determine harvest date and fruit quality, and how to conduct those analyses.
  • Lectures
    Lecture will be held in classroom and will be used to get teoretical knowledge about postharvest technologies used in fruit crops.
  • Practicum
    Practicum will be held in laboratory or classroom and it will provide students to see and learn to recognize symptoms of physiological disorders in fruits caused by wrong harvest date or storage conditions.
  • Seminars
    Seminars will be used so students learn how to use relevant scientific and professional literature with critical review. This will be performed as written work or case study.
