- Abstract
With quinoa as the main raw material, skim milk powder, green tea powder and xylitol as auxiliary materials, compound meal replacement powder was prepared. The extrusion parameters of quinoa powder and the formula of quinoa green tea nutritional meal replacement powder were optimized by single factor test and orthogonal test, and the preparation and nutritional composition of quinoa green tea nutritional meal replacement powder were studied. The results showed that the optimal extrusion parameters of quinoa flour were 18% moisture content, 190 °C extrusion temperature and 260 r/min screw speed. The optimal formula of quinoa green tea nutritious meal replacement powder was 51% quinoa powder, 24% skim milk powder, 10% green tea powder and 15% xylitol. The best water temperature of quinoa green tea nutritious meal replacement powder was 80 °C, the best ratio of flavor-liquid was 1:6, the agglomeration rate of meal powder was 3.72%, and the stability index of meal replacement was 3.91%. The prepared quinoa green tea nutritious meal replacement powder was a nutritious and delicious meal replacement product.
