Jams were prepared according to the report of Suutarinen,
Honkapa¨a¨, et al. (2000) without the addition ofexogenous pectins. After 1 week of storage at 4 C, jam
berries were separated from medium, both fractions were
weighed and latter subjected to textural analysis. The integrity
of jam berries was estimated as the percentage of
weight of whole berries present in the jam relative to the
total weight of jam. As can be observed in Fig. 1, the
weight of berries recovered from jams prepared from transgenic
lines was higher than the weight of berries from control
jam, although differences were only statistically
significant in the case of Apel 23.
