H. Guzmanmaldonado et O. Paredeslopez, PRODUCTION OF HIGH-PROTEIN FLOUR AND MALTODEXTRINS FROM AMARANTH GRAIN, Process biochemistry, 29(4), 1994, pp. 289-293
The feasibility of producing a high-protein flour (HPAF) and maltodext
rins from whole amaranth flour was explored using a commercial prepara
tion of alpha-amylase. The yields of HPAF and maltodextrins were 47-49
% with 31% of protein content, and 51-53% with a protein content of09%
respectively which is within the recommended level (< 1.0%). The prot
ein digestibility of HPAF (75 6%) was comparable to that of raw flour.
The flour dispersibility of HPAF was 75%. The protein enriched flour
may be used as a dry milk extender. Amaranth maltodextrins showed a si
milar Hunter colour and physical appearance to those exhibited by a co
mmercial product. When amaranth maltodextrins were fractionated on Bio
gel P-10 two principal peaks, with degrees of polymerization of 1 and
2, were obtained. This suggests that amaranth grain may be used for th
e production of the two cited products.
