RESEARCH RESEARCH MOTIVEMOTIVE We doubted why there would not almost be any
bread of the main ingredients except wheat. → Can the bread of the main ingredients be
made except wheat?
We think that, if we can make of from grain other than wheat, It is useful for an improvement of the eating habits of people with wheat allergy.

11 .BASIC KNOWLEDGE ABOUT .BASIC KNOWLEDGE ABOUT BREAD BREAD
(1)BREAD IS…①leavened bread ・・・ Made by adding
water, yeast, salt,
etc. to normal flour or rye flour.②unleavened bread ・・・ Made without
adding yeast. For example, nan.

Flour ・ Strong flour ・・・ it that the protein rate is 12% or more.
・ Medium-strength flour ・・・ it that the protein rate is just over or below 9%.
・ Weak flour ・・・ it that the protein rate is is 8.5% or less.

・ The crack of barley is conspicuous. ・ There is no great difference in a size of bread. ・ It is becoming brown in order of strong one>weak one>barley.

*RECIPE①
Flower ,salt and dry yeast is put in and
mixes lightly
Water put in in the center. And it
is mixed and melted sugar by
a fingertip.
Mixes adding water little by little
A shortening is added and mixes well.
Before fermentationAfter fermentation After it kneads 15 minutes or more, it is moved to the bowl which applied a little oil. And do the primary fermentation
*RECIPE②
we carved it after fermentation.
The air of bread is extracted by tap.
dough is kept for 20 minutes. ( Bench tim
e )
The form of dough is fabricated again.
And, It is made to ferment for 40 minutes as secondary
fermentation.
It bake bread at 200 degrees for 40
minutes.

THE MOST DELICIOUS ONE IS…
Ten people evaluate these breads.
It was referred to as 4, 3, 2, and 1 at delicious order.
Bread placed for 45 minutes
is the most delicious!
CONSIDERATIONCONSIDERATIONFresh baked is not necessarily delicious.
The feel made into fluffy increases as time is formed because moisture in dough flies.
We cannot be asserted bread placed for 45 minutes is the most delicious.
CONSIDERATIONCONSIDERATIONThe dough swells easily has been
confirmed if it contain gluten.
It is not exact if a cup in which the memory was entered is used.
* The device for making better bread
* Substances other than gluten add on bread. And comparison of how to swell .
* Evaluation of the delicacy of bread
