Different raspberry cultivars are grown in Latvia suitable both for fresh market and for
processing. Fresh local red raspberry is available for consumers from July to October. Information
about the physical, chemical, and morphology properties of raspberry fruit is essential for
understanding the behavior of the product during the postharvest operations such as harvesting,
transporting, sorting, grading, packaging and storage. Knowledge of the physicochemical
properties of red raspberries is essential because variations in the levels of these properties may
exist between cultivars. New varieties of plants were used to describe and compare the fruit
quality of red raspberry cultivars: ‘Daiga’, ‘Shahrazada’, ‘Norna’ and ‘Polana’ grown in Zemgales
region of Latvia. The samples were collected from farm ‘Pluģi’ the full stage of ripening. The
current research aimed to investigate and determine the chemical composition (total phenolic
content (TPC), total flavonoid content (TFC), titratable acidity (TAc), total soluble solids content
of raspberry fruits, the physical parameter pH, and color. Presented morphological parameters of
fruit included their weight, receptacle length (Rl), receptacle width (Rw), fruit length (Fl), fruit
width (Fw), weight of fruit (M), number of seeds. Research results showed significant differences
in all chemical and physical characteristics as well as in morphology properties (P < 0.05)
between cultivars.
