Problems solved by technology

Despite being used in jams and jellies, the crushed fruit pieces are too small to be used as snack foods or components requiring larger particles
Additionally, when crushed fruit pieces are molded, sliced, or otherwise formed into larger pieces, they tend to absorb moisture and quickly lose their integrity

Embodiment 1

[0022] Plums are harvested (typically about 80% moisture content). It is then dried in a dryer at 180°F to a moisture content of 16-17% to form low moisture, dry, whole dried plums. Since the moisture content of dried plums is usually so low that fungi and bacteria cannot grow, they can usually be stored for at least 24 months as long as they are not exposed to moisture and infection.

[0023] To pit the dried whole plums, the plums are first washed and steamed to soften them. When cooking the dried plums, the moisture content of the dried plums is increased to 28-29% to increase the efficiency of denucleation. The steamed hot plums are then pitted with an automatic plum pitter and sorted to remove any remaining pits. In all embodiments of the invention, it is necessary to remove all stones.

[0024] The pitted dried plums (28-29% moisture content) were covered with dry ice to reduce the temperature of the dried fruit to about -55 to -80°F. The frozen plums are sent to an ...

Abstract

A method of producing shattered, preservative-free dried fruit by freezing low moisture fruit (preferably having moisture content of 22 % - 30 %) prior to crushing the frozen fruit (preferably with a roller mill) to produce randomized, shattered fruit pieces (preferably having size primarily in the range from 1 / 4 inch to 3 / 8 inch). The shattered fruit pieces are optionally dried (for example, while they are warmed in a warm air dryer) to reduce their moisture content to 22 % - 25 % prior to packaging. In an optional, preliminary processing step, dried fruit is first rehydrated to a moisture content of 26 % - 30 % (preferably 28 % - 29 %) to produce low moisture fruit. The low moisture fruit is pitted and then frozen. The frozen, low moisture fruit is then shattered (and optionally then dried) in accordance with the invention.

Description

field of invention [0001] The invention relates to a processing method of dry fruit chips without preservatives. In particular, the present invention relates to a process for processing preservative-free dried fruit pieces that have a random appearance that does not readily absorb moisture and rapidly loses its integrity. Background of the invention [0002] Small dried fruit pieces are a common industrial food ingredient used in baked trace mixes and cereals. [0003] Traditional dried fruit pieces are often sticky and will clump if not coated with cornstarch, vegetable oil or other non-stick coatings. Fruit slices without preservatives are difficult to store at moisture levels greater than 25% due to the growth of yeast and mold. Where moisture levels are below 25%, there is usually not enough free water for yeast and mold to grow. [0004] One method of processing fruit flakes is to shape the ground fruit pulp into square or rectangular pieces...
