Description
1~4S447 The present invention is directed to a metho~
for preserving high moisture content agricultural grains which become subject to bacterial degradation due to the high moisture content present. More particularly, the present invention is directed to a method for preserving such high moisture content agricultural grains by treating said grains with a specific acid/surfactant admixture.
United States Patent 3,682,653 discloses the use of a surfactant and propionic acid, in combination, as a grain conditioner lubricant for softening a mass of whole kernel grains. Essentially, the patentee employs a mixture of liquid lecithin, propionic acid, and water. The propionic acid serves to reduce the pH of the lecithin such that the lecithin becomes water disperslble.
The invention of this patent is quite different from that disclosed and claimed herein for a number of reasons.
Firstly, the patentee is not at all concerned with the pre-servation of high moisture content grains. Secondly, the patentee requires the presence of a natural amphoteric surfactant (lecithin), whereas, as will be seen from the-discussion which follows, a synthetic organic cationic or anionic surfactant is required for the instant invention to enhance the spreading factor of the acid contained in the present composition required to preserve the high moisture content grains. Non-ionic or amphoteric surfactants will not 5uffice to this end. Thirdly, one observes upon a reading of this patent, that the patentee requires propionic acid for the purpose of dispe-rsing the lecithin, whereas in the instant invention, the surfactant i5 employed for the sole purpose of dispersing the acid of the present composition in the high ~b

~45447 moisture content grain for preservation purposes.
Finally, according to the patentee, 1/4 lb. of acid per ton of grain would be required, whereas with the present invention, appreciably more acid per ton is required, and as such, the patentee's acid content would be so minimal as to prevent preservation of the high moisture content grain.
United States Patent 2,890,120 discloses a method for preserving edible plant materials, i.e., fruits and vegetables which become deteriorated via enzyme deterioration.
Specifically, the method includes applying to said plant materials, a composition containing at least an acid, a volatile oxygenated organic solvent and a surfactant. The invention of this patentee is distringuished from the inven-tion disclosed and claimed herein on at least two bases.
Firstly, the plant materials of the patentee are deteriorated via enzymes whereas the grain material disclosed in the instant invention is deteriorated through bacteria as a result of the high moisture content present. Secondly, the patentee requires the presence of a volatile oxygenated organic solvent for two reasons: (1) to facilitate the penetration of the patentee's acid through the cell walls and - membranes of his plant materials, and (2) for acting synergistically with the other components of the patentee's solution to promote enzyme inactivation. In the instant invention, no volatile oxygenated organic solvent is at all required. In fact, to employ such would be detrimental to the purposes intended to be achieved by the present inventors.
It is the primary object of the present invention to provide a method-for preserving high moisture conten~
agricultural grains.
1~45447 Accordingly, to this end, it is intended for the purpose of this invention, to employ a high moisture content agricultural grain preserving composition, which consists essentially of: (1) a food-grade organic acid, or phosphoric acid, and (2) a synthetic organic cationic or anionic surfactant for enhancing the penetration of the acid employed in this composition into the high moisture content grain, thus effecting preservation of the same. Non-ionic or amphoteric surfactants will not suffice.
By way of definition, the term "food-grade organic acid" refers to conventional organic acids known and approved for use with food products.
The term "high moisture" as it pertains to agricultural grains means any agricultural grain whose moisture content is 18% or more.
With respect to the food-grade organic acids suitable for the purpose of this invention, those acids which are preferred are those of formic acid, acetic acid, propionic acid, and lactic acid. Of these, propionic acid is the acid of choice because it not only serves the function required of an acid for the purpose of this invention, but, in addition, this particular acid is an effective fungicide and as such, enhances the preservation power of the composition employed.
However, any other food-grade organic acid approved for use by the Food and Drug Administration's "GRAS" list is acceptable also.
With respect to the concentration parameters for the acids and surfactants employed in the present composition, naturally, the c~ncentration of same will vary over wide limits, depending upon the moisture content of grain treated.
lU45447 However, generally, the following guidelines are suggested.
For one ton of grain containing 25% moisture content, the following active ingredient concentrations are suitable for applicants' purposes:
(1) Acid - 10 lbs.
(2) Surfactant - 2 lbs.
Similarly, for one ton of grain having a moisture content of 15%, the following active ingredient concentrations are suitable:
(1) Acid - 2-1/2 lbs.
(2) Surfactant - 7/10 lb.
Referring to the above examples, with respect to the grain having a moisture content of 25%, 12% of that moisture is inactive. Consequently, the amount of active water in the 25% moisture grain is actually 13% (25% - 12%).
Similarly, with respect to the grain having a 15%
moisture content, the amount of active moisture contained in said grain would be 3% (15% - 12%).
Accordingly, 15% moisture grain required 3/13 times the formula or roughly 1/4 of the formula used for application to a 25% moisture grain. This is based on perfect mixing conditions. For practical purposes, it may be necessary to use an inert diluent. Based on the foregoing guidelines, it is believed that the skilled artisan can easily calculate the amount of acid and surfactant required for applicants' purposes simply by determining the amount of moisture content contained in a particular grain and calculating the amount of each active ingredient required on a proportional basis in light of the above guidelines.
With respect to the surfactants suitable for 1~45447 applicants' purposes, applicants do not limit themselves to any particular cationic or anionic surfactant. That is, virtually any of these will suffice. However, without limitation, the following commercially available surfactants have been found to be quite suitable. Any sodium alkyl-sulfonethanolamine; any ammonium or sodium alkylarylpoly-ethersulfonate (Triton); any long alkyl chain sulfonate; any alkyl aryl sulfonate; any sulfonated fatty acid; or any sodium sulfosuccinate. Specific illustrative examples of the following aforementioned types of surfactants are: sodium dodecylsulfonethanolamine, ammonium dodecylbenzenepolyether-sulfonate, sodium dodecylbenzenepolyethersulfonate, dodecyl-sulfonate, sodium dodecylbenzenesulfonate, sulfonated myristic acid, sulfonated palmitic acid, sulfonated stearic acid and di(2-ethylhexyl)sodium sulfosuccinate.~ These and other cationic and anionic surfactants useful in the instant invention are found and described in the text entitled "ENCYCLOPEDIA OF SURFACE ACTIVE AGENTS", by Sisley and Wood, published by Chemical Publishing Company, New York, New York (1964?.
Naturally, for the purpose of this invention, more than one food-grade acid can be employed; that is, mixtures of conventionally acceptable food-grade acids are equally as suitable for the purposes of this invention.
With the foregoing in mind, the following brief explanation will provide the skilled artisan with a basis to fully understand the uniqueness and novelty of the present invention.
Firstly,- the basis of this invention is the realiza-tion that food-grade acids can be used to preserve high ~ Jr~e~r~ ~ 6 -1~45447 moisture content grain, such as corn grain or any other agricultural grain. However, a problem arises when using such an acid and mainly, the acid alone cannot normally penetrate or permeate through the high moisture content grain sufficiently to impart this preservation effect.
Consequently, the uniqueness of the instant invention is the realization that when a conventional food-grade acid and a synthetic organic cationic or anionic surfactant capable of enhancing penetration of that acid through high moisture content grains are administered concomitantly, the surfactant enables the food-graid acid to fully penetrate throughout the high moisture content grains so as to permit an overall substantial preservation effect to be achieved.
In application, one simply determines the amount of high moisture content grains to be treated as well as the amount of moisture contained in that grain. The amount of moisture contained in a particular grain can be easily determined by means well known to the skilled artisan con-cerned with the subject matter of this invention. Subsequent-ly, based upon these estimations, the basic formulation of the present invention is prepared by simply mixing together the essential ingredients. Then, the prepared formulation is applied to the high moisture content grain by any suitable means, for example, spraying the same onto the grain mass, until the high moisture content grain is saturated with the formulation.
A better understanding of the present invention will be gained from the following examples, which are simply illustrative and non-limitative thereof.
1~45447 EXAMPLE I
This example, set out in two parts (part A and part B) illustrates the "spreading factor" discussed in connection with the formulation of this invention.
Part A. (Rate of penetration of the acid through the grain mass; the ~SPREADING FACTOR") Formulation Inches per Hour 50% - Propionic acid 5.0 50% - Mixture of Propionic acid (60%) and Acetic acid (40%) 5.1 50% - Acetic acid 5.2 50% - Propionic acid and l/10% sodium alkylsulfonethanolamine* 7.5 Each of the above formulations were diluted with distilled water to the required percent. 35 mm. Pyrex tubes (specially prepared) were employed. High moisture corn (25%) was packed in the tubes at 5 lbs. per square inch at each inch level. All experiments were conducted at 70F. These values hold only for the particular batch of corn used and are not absolute, and vary with the degree of attrition if ground.
Part B. (Rate of penetration of the acid through the grain kernel; the "ABSORPTION FACTOR") Formulation Percent Absorption in Hours 50% - Propionic acid 20 24 28 28 30 37 50% - Propionic acid/Acetic acid-60/40 mixture 19 23 26 29 32 35 50% - Acetic acid 25 31 34 36 40 45 50% - Propionic acid and 1/10% sodium alkylsulfonethanolamine* 30 38 35 56 64 75 * sodium dodecylsulfonethanolamine

Finally, according to the patentee, 1/4 lb. of acid per ton of grain would be required, whereas with the present invention, appreciably more acid per ton is required, and as such, the patentee's acid content would be so minimal as to prevent preservation of the high moisture content grain.
