The invention belongs to the technical field of
food processing, and particularly relates to a method for preparing a zero-hydrogenation low-
sugar solid beverage through
spray drying. The method comprises the following steps: firstly, adding modified
lecithin and modified Arabic gum into a feed liquid according to a specific proportion, and homogenizing to obtain a
mixed feed liquid; then, a pressure
spray dryer is used for cyclic agglomeration
drying, and separated fine particles are returned to an atomization area to serve as
crystal nucleuses and are bonded with wet
fog drops to grow into large particles. Through compounding of the modified additive and a cyclic agglomeration technology, the problems that a traditional product is small in particle size, poor in reconstituability and prone to adhering to the wall are effectively solved, and the
solid beverage uniform in particle size and good in instant
solubility is prepared. The product adopts refined
vegetable oil to replace hydrogenated oil, so that zero trans-
fatty acid is realized;
polydextrose and
erythritol are used as main sweet sources, and the total
sugar content is less than or equal to 15%. The process is simple and controllable, high in
raw material utilization rate, suitable for industrial production and capable of meeting the requirements of healthy
sugar-controlled people.
