Abstract:
The main purpose of this study was to identify the assortment of apple
varieties traded in Moldova and an radiography performing on the products quality
in terms of physico-chemichal and sensorial properties. The biological material is
represented by 8 varieties of apple (Generos, Golden Delicious, Jonagold, Granny
Smith, Starkimson, Florina, Jonathan și Idared) purchased from different
supermarkets or markets. The physico-chemichal analysis consisted on
determination of dry powder, water, sugar and vitamin C content, titrable acidity,
maturation degree by starch hydrolisis and diameter, weight and firmness of apples.
Research findings indicated that apples marketed in autumn come mainly (65%)
from internal production while the imported apples representing 35%. Fruits folding
is mostly in bulk (62,5%), the difference being found in the retail packed in bags or
polythene bags, cardboard boxes and crates alveolar plates of wood or cardboard.
The results obtained for apples firmness reveals that Starkimson (17,45 UP/5 sec),
Granny Smith (20,45 UP/5 sec),Jonathan (20,45 UP/5 sec) și Generos varieties
(25,85 UP/5 sec) are distinguished by a low consistency and a degree of maturation
advanced, results that are consisistent with the degree of starch hydrolysis where the
values range between 9R to 10R projecting over the state of supramaturation for
this varieties. Therefore, it is believed that the produsts of this varieties are not
suitable for long term storage being indicated the trade on markets or on processing
units of apple in short term.
