What is the Proximate analysis of corn flour n soyflour on any past project work?

What a goofy question! You really need to explain what you are talking about.

From google.com:
prox·i·mate
ˈpräksəmət/
adjective
adjective: proximate
1.
(especially of a cause of something) closest in relationship; immediate.
"that storm was the proximate cause of damage to it"
closest in space or time.
"the failure of the proximate military power to lend assistance"
2.
nearly accurate; approximate.
"he would try to change her speech into proximate ladylikeness"
---------------------

What does that have to do with "analysis"? Very few people use corn flour or soy flour, so you need to identify what sort of work you are referring to.
