Abstract(s)
The evaluation of some physical and chemical
properties was done in order to investigate the effects of
storage in hazelnuts, under certain conditions of tempera-
ture, relative humidity and packaging. The fruit samples
used were original from Spain, Portugal and Turkey. The
storage of the nuts lasted for a month and a half, and the
conditions tested were: at room temperature; at 30 and 50 C
without control over relative humidity of the air; 30 and
50 C with relative humidity of 90 %, refrigeration and
freezing. The two types of plastic package tested were low
density polyethylene (LDPE) and linear low density poly-
ethylene The water activity was measured by a hygrometer;
moisture by oven drying until constant weight, colour with a
colorimeter and texture with a texturometer. From the results
obtained it was concluded that for a good preservation of the
hazelnuts it must be chosen the LDPE type of package and
with respect to storage conditions it should be done at room
temperature, or alternatively in refrigeration or freezing.
