Indian Patents. 278749:A PROCESS FOR PRESERVATION OF BOILED FREEZE DRIED CEREALS

Title of Invention	A PROCESS FOR PRESERVATION OF BOILED FREEZE DRIED CEREALS
Abstract	This invention relates to a process for the preservation of boiled freeze dried lentils and cereals which• comprises in the steps of soaking the lentils and cereals, boiling, freeze drying the cereal characterized in the steps of applying a barrier layer to the exposed surface of the cereal and thereby closing the pores.

Chick peas are first soaked in water, boiled and freeze, dried. A disadvantage associated with such a process is that after storage for a certain period, the chick peas become rancid. Such a rancification is due to the reason that the pores of the chick peas are exposed and subjected to atmospheric oxidation. It is known that cereals contain oil. Thus, by subjecting the cereal to the aforesaid steps, the oil is exposed to atmospheric oxidation which is responsible for rancification.

Another object of the invention is to propose a process for preservation of boiled freeze dried cereals which substantially avoid rancification. 3 Still another invention is to propose a process for preservation of boiled freeze dried cereals which is efficient.

The cereals are soaked in water, boiled, freeze dried in a manner known in the art. Specifically, in accordance with this invention, a barrier layer is applied to exposed surface of the cereals, such a barrier layer can comprise a coating or film of edible oil such as groundnut oil. 4 For this purpose, the cereal and edible oil are mixed thoroughly in a mixer. By applying such a barrier layer, the pores are closed and barrier layer no longer allows the surface to be exposed to atmospheric oxidation. By way pf example oil is added to the extent of 2 to 20% by dry weight of peas. If we add less than 2% by weight, a suitable layer is not formed on the surface of the cereal.

FIELD OF INVENTION
The invention relates to a process for preservation of boiled freeze dried cereals.
BACKGROUND OF INVENTION
Reference is made herein to chick peas as by way of example. Chick peas are
first soaked in water, boiled and freeze, dried. A disadvantage associated with
such a process is that after storage for a certain period, the chick peas become
rancid. Such a rancification is due to the reason that the pores of the chick peas
are exposed and subjected to atmospheric oxidation.
It is known that cereals contain oil. Thus, by subjecting the cereal to the
aforesaid steps, the oil is exposed to atmospheric oxidation which is responsible
for rancification.
OBJECTS OF THE INVENTION
An object is this invention is to propose a process for preservation of boiled
freeze dried cereals.
Another object of the invention is to propose a process for preservation of boiled
freeze dried cereals which substantially avoid rancification.

3
Still another invention is to propose a process for preservation of boiled freeze
dried cereals which is efficient.
Further objects and advantages of this invention will be more apparent from the
ensuing description.
At the outset of the description that follows, it is to be understood that the
ensuing description only illustrates a particular form of this invention. However,
such a particular form is only an exemplary embodiment and is not intended to
be taken restrictively to imply any limitation on the scope of the present
invention.
BRIEF DESCRIPTION OF INVENTION
According to this invention there is provided a process for the preservation of
boiled freeze dried cereals which comprises in the steps of soaking the cereals,
boiling, freeze drying the cereal characterized in the steps of applying a barrier
layer to the exposed surface of the cereal and thereby closing the pores.
The cereals are soaked in water, boiled, freeze dried in a manner known in the
art.
Specifically, in accordance with this invention, a barrier layer is applied to
exposed surface of the cereals, such a barrier layer can comprise a coating or
film of edible oil such as groundnut oil.

4
For this purpose, the cereal and edible oil are mixed thoroughly in a mixer. By
applying such a barrier layer, the pores are closed and barrier layer no longer
allows the surface to be exposed to atmospheric oxidation.
By way pf example oil is added to the extent of 2 to 20% by dry weight of peas.
If we add less than 2% by weight, a suitable layer is not formed on the surface
of the cereal. If we add more that 20 %, then no additional beneficial results are
achieved.
DATED THIS 3RD DAY OF SEPTEMBER 2007

This invention relates to a process for the preservation of boiled freeze dried lentils and cereals which• comprises in the steps of soaking the
lentils and cereals, boiling, freeze drying the cereal characterized in the steps of applying a barrier layer to the exposed surface of the cereal and thereby closing the pores.
