Abstract
A method for producing dry fruit chips in which starting fruit chips having an adjusted water soluble sugar concentration are freeze-dried to reduce the moisture content to a predetermined moisture content range, the freeze-dried fruit chips are microwave-dried to further reduce the moisture content to a second predetermined range and the microwave-dried fruit chips are vacuum-dried to still further reduce the moisture content to a range suitable for ready eating as snack fruit.
Claims5
A method for producing dry fruit chips for ready eating as snack fruit comprising the steps of freeze-drying fresh fruit chips having a predetermined volume and an adjusted water-soluble sugar concentration in the range of 6-25% by weight to reduce the moisture content in said fresh fruit chips to 15-60% by weight so as to maintain the predetermined volume of said fruit chips, microwave irradiation-drying said freeze-dried fruit chips under vacuum to thaw the remaining moisture content and to uniformly disperse the water-soluble sugar concentration throughout said freeze-dried fruit chips and to further reduce the moisture content to 10-40% by weight, and vacuum-drying said microwave-irradiation dried fruit chips to still further reduce the moisture content to below 5% by weight so as to produce dry fruit chips having a moderate hardness.
