In this study, the effects of pretreatments, freezing and
thawing methods on the quality of mandarin and strawberry were investigated.
Individual quick freezing (IQF,-15ºC) and conventional static methods (-18ºC
and -24ºC) were applied as freezing methods while immersing sugar and citric
acid solutions as pretreatments. Thawing was carried out in a refrigerator
(4ºC, 4 hours) and in a microwave (2 min). The color and texture of the samples
improved and the drip loss after freezing decreased with immersing into sugar
solution before freezing. Immersion into citric acid were found a better way to
protect vitamin C after thawing. Quick-freezing significantly reduced the drip
loss compared to conventional freezing. Microwave thawing is superior to
thawing in the refrigerator considering drip losses. The fast freezing method,
IQF is emphasized by reducing time and quality losses.
