Laboratory of Quality Vegetable Raw Materials

Scientists of laboratory execute investigations of vegetable raw materials quality, arrange seminars, participate in national and international conferences, disseminating their research results, and develop international cooperation, carries out business orders, improving competence by undergoing training. Scientists of laboratory cooperate with scientists from Warsaw University of Life Sciences, Wroclaw University of Environmental and Life Sciences, Institute of Environment and Ecology Faculty of Forest Sciences and Ecology, Public Limited Company “Rūta” UAB, UAB „Franmax“.

RESEARCH ACTIVITIES

  • Chemical composition of vegetable raw materials and their changes during ripening process;
  • Storage of raw materials in controlled atmosphere chambers with different air parameters;
  • Quality of processed products;
  • Sensory evaluation of food raw materials and products;
  • Biology of harmful organisms, their ecology, physiology, toxicology in the controlled environment.

SERVICES

  • Chemical analysis of vegetable raw materials in accordance with international and Lithuanian standards:
  • sample preparation for chemical analysis – homogenization, drying, crushing;
  • chemical analysis of vegetable raw materials (including feed) – ascorbic acid, carotenoids, crude protein and nitrogen, crude ash, pH, nitrate, potassium contents, etc.
  • Qualitative analysis using non-destructive and express methods:
  • moisture content analysis by express method (moisture analyser);
  • vegetable raw materials analysis by near infrared spectroscopy (near infrared analyser);
  • vegetable raw materials colour analysis by colour analyser.
  • Analysis of volatile organic compounds of food products and raw materials using e-nose.
  • Raw materials and products texture analysis by texture analyser.
