A sensory assessment was carried out by a trained panel (who
were familiar with the major sensory attributes of good quality
berries: taste, aroma, texture and colour of the samples), consisting
of 8 women and 3 men, using an unstructured 15-point hedonic
scale, where 0 represents the worst, and 15 the best condition,
meaning very good or very intense, in order to evaluate the
packaging appearance and also its influence on fruit aroma and
flavor. The raspberries and blueberries were stored at 5 C for 4 and
18 d, respectively. These fruits originated from the south of Chile
and the storage studies commenced a day after harvest (December,
2012). The samples (125 g) were held at ambient temperature
(around 25 C) 30 min before the test, coded with 3-digit random
numbers, and served simultaneously under normal laboratory
light.
