  • Patent number: 4451488
    Abstract: A shelf stable, intermediate moisture, food bar having a soft and chewy texture with good taste is disclosed. Lowered sugar content and good texture and taste characteristics are maintained through the use of a combination of at least two polyhydric alcohols in varying ratios, one of which comprises a sugar alcohol and the other either glycerol or propylene glycol. In preferred embodiments the two polyhydric alcohols are glycerol and sorbitol employed in a ratio of glycerol to sorbitol in the range 1:1 to 5:1. Despite a low total sugar content the water activity may be maintained in the 0.2-0.55 range through the use of such polyhydric alcohols while achieving a soft texture.
