<p>Softness retention characteristics of raisins are improved by applying to the surface of the raisins a pure edible polyalcohol humectant, preferably glycerol, at a rate of 20-28 % based on the weight of the raisins. The raisins and humectant are then tempered by immersing the raisins and humectant in additional humectant solution at a temperature of 90-100 °F (32-44 °C) for a time efficient to enable the raisins to absorb the humectant to an amount of about 10-19 % by weight. The raisins are then removed from the humectant solution and thereafter dried to a moisture content of 7-20 %.</p> |
