    • Cellulose is surface-modified by coating and/or acylation with C2 to C24, in same cases primarily C6 to C22, or more narrowly C16 to C20, aliphatic acids, to obtain cellulose esters exhibiting a degree of substitution of about 0.05 or less, preferably about 0.01 or less. The surface-modified cellulose is used as a low-calorie carbohydrate replacement in edible compositions having a carbohydrate component. Baked food products such as cookies employ the low-calorie ingredient in place of a starch ingredient in some preferred embodiments. In some of these embodiments, cookies formulated with surface-modified cellulose further contain a spreading ingredient such as polydextrose; in these, the cellulose esters help to control the spread as well as provide calorie reduction. In these and other embodiments, the food products can also contain reduced fat or a low calorie fat substitute and/or an artificial sweetener to provide further calorie reduction.
    • 纤维素通过用C2至C24进行包衣和/或酰化进行表面改性,在相同情况下主要为C6至C22或更窄的C16至C20脂族酸,以获得显示出约0.05或更低取代度的纤维素酯 约0.01以下。 表面改性纤维素用作具有碳水化合物组分的可食用组合物中的低热量碳水化合物替代物。 在一些优选实施方案中,烘烤的食品如饼干采用低热量成分代替淀粉成分。 在这些实施方案的一些实施方案中,用表面改性纤维素配制的曲奇饼还含有铺展成分如聚右旋糖; 在这些中,纤维素酯帮助控制扩散以及提供卡路里减少。 在这些和其他实施方案中,食品还可以含有还原脂肪或低热量脂肪替代物和/或人造甜味剂以提供进一步的热量减少。

    • Integration of an acid recovery system in the manufacturing of cellulose esters may include heat recovery from a carboxylic acid recovery distillation column by solvent extracting a weak acid stream to form a first overhead stream and a first bottoms stream; distilling the first overhead stream in a distillation column to form a second overhead stream and a second bottoms stream; sending at least a portion of the second overhead stream to a heat exchanger via a process inlet; sending a boiler feed water make up stream to the heat exchanger via a water inlet; and cooling the at least a portion of the second overhead stream in the heat exchanger, such that the at least a portion of second overhead stream exits the heat exchanger via a process outlet and the boiler feed water make up stream exits the heat exchanger via a water outlet.
