Patent Application
20130209648
The present invention relates to a wheat flour composition, a dough composition comprising the flour composition and food products comprising the wheat flour composition. It particularly relates to wheat flour composition suitable to prepare flat breads (including Indian style bread known as chapatti), noodles and pasta.
Flat breads, noodles and pasta are widely used food products.
Flat unleavened bread which is popular and widely consumed in several geographies, including the Indian subcontinent. Such bread is typically made from a dough, which in turn is made by mixing water with wheat flour. Dough balls are then rolled using a rolling pin. The bread needs to have several qualities such as softness, good tearability (as the breads are usually eaten by using hands without using knife/fork etc), texture, chewability and flavour.
The bread quality depends on several factors, and one of the major factor is the starting wheat flour composition. Wheat flour composition is also important as it affects the rheological properties of dough that determine ease of kneadbility and stickiness of dough, which in turn affect the rollability of the dough balls.
Additives such as guar gum are known to be added to wheat flour compositions for making chapattis in order to improve rheological properties. Shahzadi et al (International Journal of Agriculture & Biology, Vol. 7, No. 1, 100-104, 2005) disclose wheat flour compositions comprising 10% chickpea flour and 1% guar gum.
Wheat flour compositions comprising guar gum alone at 2% to 3% by weight are also disclosed.
However, it is found that addition of gum at higher levels, although helpful in improving colour and rheological properties of dough, suffer from a beany odour experienced during preparation of the dough and during consumption of the flat bread.
The same problems have been found in noodles where gum has been added to improve rheology, such as fried noodles and pasta.
It is therefore an object of the invention to provide a wheat flour composition having an improved dough rheology, but without having a beany note in the sensory appreciation.
Surprisingly it has been found that a wheat flour composition comprising chick pea flour and guar gum, is easily processed into a dough that is soft and can easily be processed into flat breads, noodles or pasta, and the baked product (flat bread, chapatti, noodle or pasta) that is also soft and yet has acceptable sensory properties.
Present inventors have also found that the beany odour caused by gum may be overcome by addition of chick pea flour in certain proportions.
According to a first aspect of the invention there is provided a wheat flour composition comprising
According to a second aspect of the invention there is provided a dough composition comprising:
According to a third aspect of the invention there is provided a baked good obtained by the process comprising the steps of:
According to a fourth aspect of the invention there is provided a noodle comprising the dough according to the invention.
According to a fifth aspect of the invention there is provided a pasta comprising the wheat flour composition according to the invention.

The invention will now be demonstrated with help of examples. The examples are for the purpose of illustration only and do not limit the scope of the invention in any manner.
The procedure for preparing chapatti is given below:
Annapurna® (Hindustan Unilever Limited) wheat flour was used in the experiments. The particle size was in the range of 50 to 500 microns with 75% passing through a sieve of 150 microns.
Guar gum was obtained from M/s. Ace gum industries, India with a particle size where 100% gum passed through 250 micron sieve.
Chickpea flour (dehusked) was obtained from Avent Agro Pvt Limited, India.
Mung beans (comparative) were obtained from the market, ground and a flour was obtained with a particle size in the range 50-600 microns and 63% of the mung bean flour passed through 250 microns.
Wheat bran was obtained from a wheat processing mill in Bangalore, India. The particle size of wheat bran was such that 75% of the bran passed through a 150 micron sieve. The wheat flour composition was prepared by mixing all the ingredients. Chapattis were made from the wheat flour compositions using the following protocol
100 grams of the whole wheat flour composition is placed in a plate in form of a heap with a depression at the centre and 60 mL water is added into the depression. The wheat flour composition with the water is kneaded. Additional 15 mL water is added during the kneading to obtain dough. The dough is covered with a dampened cloth for 30 minutes. Dough is formed into four dough balls each weighing 25 grams and the remaining dough is transferred for evaluation.
The dough ball is dusted with dry wheat flour by rolling in a container filled with dry wheat flour and placed centrally on a circular rolling platform of 10 cm diameter. The dough ball is rolled with a rolling pin to form a roughly circular sheet of about 10 cm diameter and of thickness in the range of 2-3 mm over the entire sheet. Dry wheat flour composition is dusted on the rolling platform or on the surface of the sheet sprinkled during rolling to avoid dough sticking. If the dough is sticky, more dusting with dry wheat flour is done to avoid sticking of the dough to the rolling pin or platform.
The baking is placed over a gas flame. When the pan is heated to reach a temperature of 150° C., the sheet is transferred on to the pan. The sheet is baked for 15-20 seconds, flipped and baked further for 15-20 seconds. After baking on both sides, the sheet is directly baked on an open flame for about 2-3 seconds till the sheet puffs completely.
Chapatti texture, dough rheology and dough aroma were evaluated by 5 panellists. The scores for each parameter were qualitatively attributed according to the scale given below and final scores are reported as median scores. The qualitative ratings for each of the evaluated parameter are explained below.
1—same texture as compared to control chapatti made with whole wheat flour—Preferred
2—Slightly rough texture but acceptable
3—Could not be evaluated as chapatti could not be rolled.
1—Softer dough, easier to roll as compared to control chapatti made with whole wheat flour
2—Softer dough, easier to roll, however some dusting is required to roll to avoid stickiness
3—Similar to 2, but more dusting is required, no peripheral breakage of the sheet
4—Similar to 3, but with slight peripheral breakage.
5—Too sticky to roll
1—Beany note masked, mild chicpea note—most preferred
2—Very light beany note, mild chickpea note—preferred
3—Mild beany note, mild chickpea note—acceptable
4—Beany note, mild chickpea note—not acceptable
5—High chickpea note,—not acceptable
Chapattis were made from various wheat flour compositions and various parameters such as dough aroma, dough rheology and chapatti texture were evaluated. The results are tabulated below
From the results, it is clear that the wheat flour compositions within the present invention provide better dough with better rheology without compromising on the dough aroma or chapatti texture.
Chapattis were made from wheat flour compositions similar to that of Example 5 in all respects except with different legume flours. The results are tabulated below.
The results indicate that legume flours other than chickpea flour can also be used to provide dough with good rheological characteristics without compromising dough aroma or chapatti texture. The results also indicate that the legume flour that passes through 300 micron sieve provides better dough aroma as compared to legume flour that is retained on 300 micron size.
Chapattis were prepared from a wheat flour composition, tabulated below along with the results of evaluation of the organoleptic properties of chapatti and the dough.
From the results it is clear that addition of bran results into good organoleptic properties.
Chapattis were made from various wheat flour compositions and various parameters such as dough aroma, dough rheology and chapatti texture were evaluated. The results are tabulated below
From the results, it is clear that the wheat flour compositions within the present invention provide better dough with better rheology without compromising on the dough aroma or chapatti texture. The addition of Barley counteracts the negative rheology effects of high legume (chick pea) flour containing compositions.
At higher levels of chickpea, adding Barley further overcomes the strong chickpea notes and thereby improves the sensory properties of the dough and the chapatti.
For the noodle examples, a similar scale as for the chapatti (Indian flat bread) has been used.
The noodle appearance, texture and taste were evaluated by 4 panellists. The scores for each parameter were qualitatively attributed according to the scale given below and final scores are reported as median scores. The qualitative ratings for each of the evaluated parameter are explained below.
1—Same appearance as compared to control—Preferred
2—Slightly different but acceptable
3—Could not be evaluated as noodles could not be formed (too dark).
1—Same as compared to control made with wheat flour.
2—Similar to control with good noodle texture and bite.
3—Similar to control with slight hardness in bite but acceptable.
4—Slightly harder than control and slightly sticky/slimy.
5—Hard and slimy texture not good and not acceptable.
1—No beany note or chickpea note—most preferred
2—Very light chickpea note, mild chickpea note—preferred
3—Mild beany note, mild chickpea note—acceptable
4—Chickpea note, strong chickpea note—not acceptable
5—V. strong chickpea note,—not acceptable
