Method for the preservation of food compositions of the pancake, fritter and similar paste type

A method for ensuring the long term preservation of food compositions of the paste type containing essentially cereal flour, eggs, sugar, milk or a milk substitute such as a soya bean alimentary filtrate and flavoring products, according to which the paste constituents are distributed into two phases, a powder phase and a sterilized liquid phase, wherein the powder phase includes the whites of egg in addition to the flour and sugar, and the liquid phase includes the yolks in addition to the other constituents, each of these phases being introduced in a distinct packing, conveniently prepared, notably aseptized, with a view to a long preservation of the phase it contains.

BACKGROUND OF THE INVENTION 
The present invention relates to a method allowing a long preservation of 
food compositions of the pancake, fritter, blini and similar paste type. 
It is known that in the composition of pastes of this type are constituents 
of two kinds are included, 
on the one hand, flour, whatever its origin, for example, wheat and 
buckwheat the starch they contain causing, during the cooking of the 
paste, a cross-linking phenomenon imparting to the products obtained a 
very particular texture; 
on the other hand, elements more easily soluble in water, such as eggs, 
sugar, salt, milk and/or soya bean alimentary filtrate, and flavoring 
products. 
The problem with which one is confronted in providing long term 
preservation of compositions of this kind comes from the fact that taking 
in account the legal provisions governing the matter, there is required a 
total sterilization by heating at a high temperature: 
either, presently, 115.degree. C. for 10 min. 
or, 145.degree. C. during 3 min, 
There is caused as soon as a temperature of 60.degree. C. is reached the 
destruction of the starch grains, making them unsuitable for the 
cross-linking which has just been mentioned, and making impossible the 
formation of the desired products. 
It should be added that in addition to the legal impossibility of having 
recourse to the addition to the composition of conservators, antibiotic or 
others, it is practically not possible to call upon sophisticated 
techniques such as ionization, because of their prohibitive cost, without 
the certainty of obtaining a total sterility. 
SUMMARY OF THE INVENTION 
The invention allows solving the problem thus posed in a particularly 
simple and economic way. 
It consists essentially in distributing into two phases the constituents of 
the paste: a powder phase including the whites of egg in addition to flour 
and sugar, and a liquid phase including the yolks in addition to the other 
constituents, each of these phases being introduced in a distinct packing, 
conveniently prepared, notably aseptized, with in view the long term 
preservation of the phase which it contains. 
Each packing consists in a packing of the aseptic type, the atmosphere in 
the one which contains the flour being chemically inert, preferably made 
of an inert gas. 
The reunion of the two phases is provided, in an extemporaneous manner, by 
means of the instructions supplied to the consumer.

DETAILED DESCRIPTION OF THE INVENTION 
The method according to the invention can be advantageously put in practice 
by means of packaging, an embodiment of which is being described hereafter 
with reference to the accompanying drawing, it being made clear that it is 
only a non limiting example: 
In this example, the packaging is made of two superimposed enclosures, made 
of any appropriate material, the upper enclosure 1 containing the liquid 
phase and the lower enclosure 2 containing the powder phase. These 
enclosures are assembled by any means so as to obtain a tight homogeneous 
block. 
The upper enclosure is formed with an orifice 3, closed by a lid made of a 
material allowing an easy perforation, by means of a stick 4, attached 
outside the package. 
The lower enclosure is separated from the upper enclosure by a membrane 5, 
also in a material (an aluminium foil for example) adapted for being 
easily perforated by means of stick 4. 
The volume of the lower enclosure is determined so as to form a space for 
containing the powder phase, and a space corresponding to the volume of 
liquid contained in the enclosure 1. In addition, an extra space is 
provided so that, during use, and once the orifice 3 has been uncovered 
and surface 5 separating the two enclosures has been perforated, and once 
the mixture of the two phases has been thus effected, one may complete 
this mixture by stirring the medium without necessary overflow. 
Of course, the invention is in no way limited to the example treated and 
can be the object of many variants without departing from its scope.
