Worldwide the consumption of fruit and vegetables is increasing due to the dietary guidelines
recommended by nutritionist. Because of their high content on phenols, vitamins, mineral
and antioxidants, berry fruits are consumed not only in fresh forms but also as processed and
derivative products such as juices, yogurts, jellies and dried fruits. As a high consumed red
fruit, sweet cherry has been the focus on some studies, mainly regarding bioactive
compounds content. “Sweetheart” cherries from São Julião region (Alentejo, Portugal) from
two different production campaigns were kept in different storage conditions in order to
evaluate both the environmental and storage effect on some physical-chemical properties and
phenolics. Cold conditions - Cold (1 ºC, 95% RH) and modified atmosphere - MA (1 ºC,
95% RH with micro-perforated bags of Pplus®, Sidlaw Packaging, Bristol, UK) were tested.
In order to establish the appropriate storage conditions, individual phenolic acids and
physical-chemical properties were analysed during two consecutive years. Results show a
general decrease on phenolic compounds content between cherries from both years. It is also
observed that MA conditions do not affect significantly both phenolics and physical-chemical
parameters when compared with Cold conditions. Additionally, it is observed similar
behaviour on Cold and MA sweet cherries regarding its pH, total soluble solids content
(TSS), titratable acidity (TA) and colour and individual phenols during storage time.
Concluding, these results show, as expected, changes between cultivars which may be
correlated with the environmental conditions on different years.
