The present invention relates to the process for preparing mustard
powder. More particularly the present invention relates to process for dehulling
the mustard seeds and still more particularly the present invention relates to
dehull the mustard seeds maintaining its natural flavor and long shelf-life,
without using any water or moisture in any form.
Mustard seeds are the small round seeds of various mustard plants. The
seeds are usually about 1 or 3 mm in diameter. Mustard seeds may be colored
from yellowish white to black. They are important spices in many regional
foods. The seeds can come from three different plants: black mustard (Brassica
nigra). brown Indian mustard (B. juncea), and white mustard (B. hirta/Sinapis
alba). Br. Compestriss.
Mustard Seed Powder is used in Indian kitchen like anything. Same is
used for making curries, gravies and is also used as a flavouring agent. This is
used both for vegetarian and non- vegetarian food stuffs. The use of mustard
powder enhances the taste of food stuff and mustard powder is made from
mustard seeds. Botanical name of mustard seeds BRASSICA
COMPESTRIS/BRASSICA JUNCEE/BRASSICA NAPUS/BRASSICA ALBA
which occurs in abundance in certain parts of India particularly in North India
such as Rajasthan, Uttar Pradesh, Punjab, Haryana and Madhya Pradesh.
Mustard seeds are the proverbially small seeds of the various mustard
plants. The seeds are about 1 to 3 mm in diameter, and rnay be colored from
yellowish white to black. They are important spices in many regional cuisines.
The seeds can come from three different plants: black mustard (B. nigra), brown
Indian mustard (B. juncea), and white or yellow mustard (B. hirta/Sinapis alba).

In the Indian subcontinent they are often used whole, and are quickly
fried in oil until they pop to impart a flavor to the oil.
Mustard seeds generally take 3-7 days to germinate if placed under the
proper conditions, which include a cold atmosphere and relatively moist soil.
Mustard oil is also extracted from the mustard seeds.
The seeds, particularly the white ones, can also be ground into a flour,
and mixed to a thick paste with a little water to make the condiment mustard.
The ground mustard powder is usually mixed with ordinary flour to reduce the
strength of the resulting condiment.
While preparing mustard powder generally and as of today process is a
moist process, in that either water is added or process is conducted in presence
of moisture which creates lot of problems and extraction from moisture or
aqueous phase requires step of removing moisture from the reaction as final
product should not contained moisture or be in aqueous phase. This removal of
moisture is lengthy process and time consuming and costly.
The object of the present invention is to prepare mustard powder and not
mustard oil. However, reference has been made to oil as one of the end products
of mustard seeds which powder is used in Indian kitchen to enhance the taste
and aroma of the gravy or curry.
Other ingredients can be used to mix mustard, for example, sugar, honey,
vinegar, wine, or , milk.

When initially mixed the sauce is mild in flavor, but it develops in time.
Strong mustard has a very powerful (and painful) effect on the nasal membranes
if eaten carelessly.
The whole seeds can be soaked in liquid before grinding to create whole
grain mustard.
It is possible to buy ready prepared mustard (condiment) in many places.
Mustard seed's hot and spicy flavor enhances meats, fish, fowl, sauces,
and salad dressings. Whole mustard seed may be used in pickling or in boiling
vegetables such as cabbage or sauerkraut. Brown mustard seeds are an
important flavoring in Indian dishes.
Dehulling of mustard seeds is necessary to remove the outer covering of a
seed used as feed. Improve the nutrient value of the grain. The hulls may be
used separately as a roughage supplement.
Thus dehulling is important aspect before mustard seeds can be used for
different purpose. Such uses include
These mustard seeds are known in Hindi/Urdu as sarson and in Punjabi as
sarron. These are used as a spice in North India. One of the oldest uses of
Mustard Seed has been as an emetic, a medicine that provokes vomiting. This is
especially valuable when used in narcotic poisoning. Scientists are searching for
innovative uses for mustard seed meal, hoping to increase profitability for
mustard producers, Mustard (Seed) Recipes for Home Cooking. This list
includes many different homemade mustard recipes along with recipes using
prepared mustard, mustard powder, to Treat Body Pain.

Thus dehulling is important aspect and dry mustard dehulling is known.
Attempts have been made by CFTRI, Mysore for wet mustard dehulling.
Likewise CIPHET, Ludhiyana have made floatation dehulling.
However, these known methods by CFTRI ,Mysore and CIPHET,
Ludhiyana have certain disadvantages in that same are time consuming process
and cost is high. The final product becomes rancid with off taste and flavor after
a short time.
Process for dehulling of mustard seed is known in art.
However, the prior art discloses only the method which is not dry in
nature rather process is conducted in moist atmosphere which creates a lot of
problems in a country like India.
Process comprises of cleaning, grading and decortications where process
is not dry in nature and one used moisture for decortication. The use of moisture
of known art is obvious in that energy is time consuming, costly and obtained
mixture is poor in quality.
The object of present invention is to develop a method which is entirely
dry in nature and whole process is moisture free. Thus the obtained product is of
better quality. These objects have been achieved by process of this invention.
These and other objects have been achieved by the process of the
present invention which has inter alia following advantages:
a. the developed process a dry milling process to dehull the mustard
maintaining its natural flavor and long self-life. The total process takes
very short time and is low cost. Wear and tear is very low;

b. the mustard -Black/Yellow/Brown/Oriental is cleaned and graded. The
graded mustard is pulverized in the stone mill in daliya form (Coarse).
Now the seed coat/Hulls and powder with fine broken pieces of mustard
seed are separated by air on vibratory gravity separator. On the other side
we get the dehulled mustard cotyledons from the gravity separator. This
process occurs in between 12 to 48 Degree centigrade as per atmospheric
conditions;
Ph is not applicable in this process;
The process adopted is dry mustard dehulling process.
According to the present invention there is provide process for dehulling
of mustard seed which comprises :-
(i) cleaning and grading;
(ii) pulverization of mustard; and
(iii) decortication of mustard
process for dulling of mustard seed which comprises (a) grading the mustard
seed to obtain bold mustard of size 2-3 mm (dia); (b) the bold seeds are
pulverized by known method sch as in stone mill/plate mill; (c) decortication
by known method whereby seed coat/huyld separated from cotyledons; thus
we get the better quality.
Normally in the known seed/pulverized seed is cleaned into water to
separate the seed coats from cotyledons. This use of moisture is totally
eliminated and thereby whole process is moisture free and finally grinding the
cotyledons seeds.

We shall now describe the present invention with reference to
accompanying examples which are given by way of illustrations but does not
restrict scope of the present invention.
Example 1.
100 kg of mustard seed is taken and same is subjected in step of dehulling
and obtained about 60-65% of cotyledons. After removing 30-35% of seed
cqat/hulks by known method while taking care in moisture free atmosphere.
In known art pulverized seed which floats in water to remove the seed
coats. By use of moisture free atmosphere this step was totally avoided and
thereafter same is subjected to step of grinding of decorticated cotyledons to
obtain fine powder of size 18-25 mesh pass.
Finally this powder is checked and packaged in poly pouch.
The present invention relates to dry process of obtaining mustard powder
which of superior quality and cost effective.
In this process it can be made any mustard such as oriental, yellow and
black.
