The Use Of African Breadfruit (Treculia Africana) And Soyabean (Glycine Max) As Nitrogen Source In Wort For Yeast Metabolism
ABSTRACT
Soyabean (Glycine
max) and African breadfruit (Treculia africana) are excellent sources of
protein. However as investigations into the brewing potential of sorghum
continue, its biochemical and physical deficiencies have become noticeable.
Sorghum wort was found to contain significantly lower level of nitrogen in the
form of amino acid to achieve a good yeast growth and rapid fermentation. The
use of soyabean and African breadfruit to supplement the low nitrogen content
in sorghum wort was studied. Infusion mashing method was employed. A ratio of
10:1 of sorghum grist to soyabean cake and breadfruit cake was adopted. The
result obtained indicates that free alpha amino nitrogen content of 187.l0mg/L
(soyabean) and 162.42mg/L (breadfruit) within specification (150-190rng/L)
werthe recorded against 145.5mg/L which was obtained from sorghum wort. The
fermentability of the sorghum wort produced increased from 40.56% to 60.32% and
64.62% when using breadfruit cake and soyabean cake respectively. The use of
soyabean and breadfruit as nitrogen source in sorhum wort should therefore be
encouraged. in the sensory characteristics accessed, samples supplemented with
soyabean gave the best characteristics.
