Strawberries (F. vesca cv. Camarosa) were purchased in a local
market from La Serena city (Chile) and stored at 5.0 1.0 C until
further processing. The fruits were selected visually according to
size and maturity level. Then, the fruits were washed and dried
with absorbent tissue paper. After that, they were manually cut
with a stainless steel knife into 1 cm thick slices. The osmotic
solutions were prepared using commercial sugar (Iansa Co. Chile)
and distilled water. The concentration of sugar used was 40 Brix.
From each fruit, 3 slices were obtained. Then, they were weighed
individually and submerged in the hypertonic solution in a 1/4
(g/g) fruits to syrup ratio at ambient temperature and packaged
in polyethylene bags prior to HHP processing (Nuñez-Mancilla
et al., 2011).
