Description

FIELD OF THE INVENTION

The invention relates to the field of agriculture, food safety and post-harvest food treatments to address the lack of useful methods to prevent bacterial contamination of dry raw agricultural commodities. The novel composition provides unexpectedly high degree of control required for food safety. The invention also relates to a method of use thereof.
More particularly, the invention relates to a composition of water-soluble ingredients, said water-soluble ingredients comprising at least one oxidizer, at least one lower alcohol and optionally at least one wetting agent, which when solubilized in a water-containing solvent forms an aqueous, synergistic composition useful for the control of pathogens and/or the prevention of diseases associated with the presence of said pathogens in and/or on seeds, more preferably edible seeds such as hemp seeds, flax seeds or chia seeds. Also, the invention relates to an aqueous, synergistic composition obtained by dissolving the above-mentioned composition in water, and relates to method and use of said aqueous, synergistic composition for the control of pathogens and/or the prevention of diseases associated with the presence of said pathogens in and/or on seeds, more preferably edible seeds such as hemp seeds, flax seeds or chia seeds.

BACKGROUND OF THE INVENTION

Published international application No. WO2007/092180 describes a fertilizer composition for application to a seed, plant, growth medium or growth solution, said composition comprising an oxidizing agent wherein bioavailable oxygen is released upon contact to the composition with water, optionally a solvent such as methyl ketone, methyl isobutyl ketone, cyclohexanonon, xylenes, toluene, chlorobenzene, paraffins, kerosene, white oil, alcohols, methylnaphthalene, trimethylbenzene, trichloroethylene, N-methyl-2-pyrrolidone and tetrahydrofurfuryl alcohol (THFA), and eventually other additives selected from the group consisting of companion cations, cation reducing agents, pH modulators, nutrients, organic compounds, penetrants, microorganisms, pesticides, fungicides, insecticides, nematocides, herbicides, water trapping agents, enzymes, surfactants, wetting agents, spreaders, stickers and growth hormones. This published international application WO2007/092180 further relates to a method of use of said fertilizer composition. However, this published international application does not provide a novel solution to control the high level of pathogens on edible food commodities.
Peracetic acid (C₂H₄O₃) in an aqueous solution is a mixture which is further comprising acetic acid (CH₃COOH) and hydrogen peroxide (H₂O₂). Typically, peracetic acid (also identified hereinafter under the acronym PAA) is produced by reacting acetic acid and hydrogen peroxide. It is also well known to generate a liquid solution comprising PAA starting from the dissolution of a powdered mixture (U.S. Pat. No. 7,291,276; UK patent application No. 2,355,198; FR patent application 2,728,171; Canadian patent application No. 2,569,025; International PCT patent application WO 95/02330 and EP patent application No. 0 648 418).
Also, peracetic acid (also known under the tradename peracid) is a strong oxidizing agent which is known for having virucidal, bactericidal, fungicidal and algaecidal properties. Peracetic acid was patented in 1950 for the treatment of raw plant tissue, especially for the treatment of fruits and vegetables, to reduce spoilage from bacteria and fungi destined for processing (U.S. Pat. No. 2,512,640). Nowadays, peracetic acid is commonly use in food processing and handling as a sanitizer for food contact surfaces and as a disinfectant for fruits, vegetables, meat and eggs (NOSB TAP Materials database compiled by OMRI, Nov. 3^rd2000, 7 pages). In the production of fruits and vegetables, peracetic aqueous solutions have been suggested to control pathogenic organisms on growing plants (U.S. Pat. No. 6,024,986; U.S. Pat. No. 6,165,483; and U.S. Pat. No. 6,238,685).
As per Applicant's published international patent application WO 2012/051699, a solution of peracetic acid generated in situ in combination with a plant defence enhancer demonstrated excellent anti-bactericidal and anti-fungal properties. More particularly, in this international patent application it was evidenced a synergy of peracetic acid and at least one plant defence enhancer for the control of pathogens in and onto growing plants. Furthermore, according to a particularly preferred embodiment of said published international patent application WO2012/051699, the presence of a surfactant in a synergistic mix of a precursor of peracetic acid and potassium silicate (i.e. a SAR inducer), enhances the release of peracetic acid when admixed with water.
However, concerning seeds, more particularly seeds having external shells, especially edible seeds such as hemp seeds, flax seeds and chia seeds, the person skilled in the art notes that existing compositions do not allow an oxidizer to cover the surface of the seeds efficiently in order to kill pathogens present thereon and/or therein.
Therefore, there was still a strong need for a composition allowing to obtain an efficient control and/or treatment of diseases associated with seeds, especially concerning seeds having external shells, especially edible grains and seeds such as hemp seeds. Also, there was a strong need for method and use allowing to control and/or treat efficiently seeds having pathogens present thereon.
Also, it is to be noted that literature did not recommend using alcohol on seeds because the person skilled in the art knows that alcohol at low dosage does not kill bacteria. In this regard, reference can be made to the content of the article of Mena et al., “Influence of Ethanol on Probiotic and Culture Bacteria Lactobacillus bulgaricus and Streptococcus thermophilus within a Therapeutic Product”, Open Journal of Medical Microbiology, 2012, 2, 70-76. In this article Mena et al. showed that ethanol added to yogurt does not affect the count of Lactobacillus sp.
Also, it is to be noted in addition to the teaching of the above-mentioned article of Mena et al. that not only alcohol does not kill bacteria at low levels but also it is used (at concentration of around 1 to 5%) as a carbon source for bacteria to promote their growth. In this regard, reference can be made to the content of the article of Smith et al., “Microbial Synergia via an Ethanol-Triggered Pathway”, Molecular and Cellular Biology, May 2004, p. 3874 -3884.
Surprisingly, the Applicant has recently discovered that when using at least one oxidizer in combination with at least one agriculturally acceptable solvent and/or wetting agent, soluble in water, and much more preferably at least one alcohol, optionally with or without at least one wetting agent (e.g. a surfactant), it is possible to obtain a synergy between above ingredients to provide an aqueous, synergistic composition, a method and a use allowing to cover the seeds surfaces efficiently with said at least one oxidizer in order and provide an efficient control and/or treatment of seeds having pathogens present thereon.
Furthermore, it is worth mentioning that the Applicant has surprisingly discovered that the presence of a wetting agent along with an oxidizer in an aqueous solution of the same:

- allows a better coverage of the seeds.

Furthermore, it is worth mentioning that the Applicant has surprisingly discovered that the presence of alcohol along with an oxidizer in an aqueous solution of the same:

- allows a better coverage of the seeds;
- helps drying the seeds after having applied the aqueous solution;
- prevents the release of mucilage from seeds such as flax and chia, and thus maintains the nutritional value and natural composition of the seeds intact; and/or
- maintains organoleptic properties of said seeds.

Furthermore, it is worth mentioning that the Applicant has surprisingly discovered that the presence of alcohol and a wetting agent, along with an oxidizer in an aqueous solution of the same:

- allows a better coverage of the seeds;
- helps drying the seeds after having applied the aqueous solution;
- prevents the release of mucilage from seeds such as flax and chia, and thus maintains the nutritional value and natural composition of the seeds intact;
- maintains organoleptic properties of said seeds; and/or
- shows an unexpected better efficiency.

Also, concerning the prevention of mucilage from seeds, it is to be noted that a person skilled in the art, would not have been motivated to use a composition containing water on seeds such as flax, which are recognized to produce mucilage when contacted with water. Surprisingly, the aqueous, synergistic composition according to the invention prevents mucilage from seeds. Preferably, an extra amount of an agriculturally acceptable alcohol may be added to said aqueous, synergistic composition in order to further reduce the amount of water in such case. Such an extra amount of an agriculturally acceptable alcohol does not affect the synergy mentioned hereinabove.
Also, it is worth mentioning that the Applicant has surprisingly discovered that contact of the aqueous, synergistic composition with the seeds can be extended up to 12 to 72 hours, thereby providing a better efficiency in reducing the pathogens. Optionally, in the case of extended contact of the seeds with the aqueous synergistic composition, it may be advantageous to lower the humitidy content of the seeds below 10% after the treatment with the synergistic solution (in order to prevent regrowth of pathogens in and/or on the seeds). The regulation of the humidity content of seeds can be achieved by any appropriate means well known to person skilled in the art.
Also, it is worth mentioning that said synergistic composition, method and use is particularly efficient to kill human pathogens such as bacteria (e.g. E. coli, Salmonella spp., Listeria monocytogenes), coliforms that may be present on the surface of said seeds, as well as yeast and mould which may be present on the surface of said seeds.

200 ml of PERCID were dissolved in 1 L water, and mixed for 5 minutes. A non-foaming PAA solution was obtained. Then, 100 ml of this non-foaming PAA was mixed with 100 ml Ethanol 94% for 10 minutes, to provide the liquid peracetic acid preparation with alcohol.

II—Preparation of Different Seeds Grains.

Seeds were mechanically cleaned and spread in stainless steel containers. Each 100 grams seeds were sprayed with 4 ml total solutions descried above via conventional trigger vaporizer. This solution is equivalent to 40 L disinfecting solution total sprayed on 1-ton seeds. Seeds, grains and spices were selected to represent all families and types of seeds, grains and spices. Another criteria was to select seeds and grains contaminated with a high count of total aerobic bacteria, yeast, mold, E. coli, Salmonella sp. and other pathogenic microorganisms.
Seeds, grains and spices treated were:

- Whole dried pea,
- Split pea dried,
- Pea fiber,
- Vanilla,
- Chia,
- Sprouted flax and chia,
- Flax,
- Hemp, and
- Black pepper seeds

Conclusion:

- The polyglycoside wetting agent (i.e. surfactant) was not bactericidal and can act as a food source for the bacteria
- Alcohol (50% concentration) applied at ratio of 40 L per 1 ton peas was not a strong bactericidal agent.
- Peracetic acid either preformed via liquid formulations or in-situ generated via powdered formulations, showed to be a strong bactericidal agent and reduced the level of bacteria, yeast and mold significantly.
- Wetting agent (i.e. surfactant) combined to peracetic acid formulations increased the efficiency of the oxidizer and showed to be synergistic with peracetic acid.
- Alcohol (ethanol) combined to peracetic acid formulations increased the efficiency of the oxidizer and showed to be synergistic with peracetic acid.
- Both alcohol and wetting agent (i.e. surfactant) increase the coverage of peracetic acid and help this limited amount of solution (40 L per 1 ton seed) to cover better the seeds and penetrate the seeds and target microorganisms. They showed a synergistic effect that is higher that the one of the peracetic acid with a wetting agent or the peracetic acid with an alcohol.

- The polyglycoside wetting agent (i.e. surfactant) was not bactericidal and can act as a food source for the bacteria
- Alcohol (50% concentration) applied at ratio of 40 L per 1 ton peas was not a strong bactericidal agent on pea fiber at used concentration (i.e. 40 L of alcohol 50% active per 1 ton).
- Peracetic acid either preformed via liquid formulations or in-situ generated via powdered formulations, was a strong bactericidal agent and reduced the level of bacteria, yeast and mold significantly.
- Wetting agent (i.e. surfactant) combined to peracetic acid formulation increased the efficiency of the oxidizer and thus showed to be synergistic with peracetic acid.

Conclusion:

- The above-mentioned solutions were sprayed on hemp seeds to achieve a reduction of the level of total aerobic count.
- The polyglycoside wetting agent (i.e. surfactant) was not bactericidal.
- Alcohol (50% concentration) applied at ratio of 40 L per 1 ton hemp seed was not a strong bactericidal agent on hemp.
- Peracetic acid either preformed via liquid formulations or in-situ generated via powdered formulations, was a strong bactericidal agent and reduced the level of bacteria, yeast and mold significantly.
- Wetting agent (i.e. surfactant) combined to peracetic acid formulations increased the efficiency of the oxidizer and thus showed to be synergistic with peracetic acid.
- Alcohol (ethanol) combined to peracetic acid formulations increased the efficiency of the oxidizer and thus showed to be synergistic with peracetic acid.
- Both alcohol and surfactant increase the coverage of peracetic acid and help this limited amount of solution (40 L per 1 ton seed) to cover better the seeds and penetrate the seeds and target microorganisms. They showed a synergistic effect that is higher that the one of the peracetic acid with a wetting agent or the peracetic acid with an alcohol.

EXAMPLE 2

A Trial Assessing the Efficacy of Powdered Formula (Powdered PAA with a Wetting Agent) in the Surface Disinfection of Hemp Seeds in a Grain Conditioning Facility

Protocol:

Several tons of hemp seeds were cleaned mechanically using regular grain conditioning equipment. The total bacterial count was determined to be about 18 million CFU/g (before mechanical cleaning and separation). After mechanical cleaning, the total bacterial count was found to be about 2 million CFU/g. This microbial load does not comply with the market standard which is 1 million CFU/g.
Treatment with Peracetic Acid and Hydrogen Peroxide Without an Alcohol and/or a Wetting Agent:
Hemp seeds (with a microbial load of about 2 million CFU/g) were sanitized with a powdered product based on sodium percarbonate, TAED and citric acid that generates peracetic acid and hydrogen peroxide in situ. An equivalent of 4 Kg of this formula were dissolved in potable water and mixed thoroughly for 10 minutes and then applied to 1 ton of hemp seeds and allowed to remain in contact with them for 30 minutes. The seeds were thoroughly dried after the treatment. The results did not show a significant reduction in microbial load as compared to untreated seeds (2 million CFU/g). These results were not satisfactory. In addition, coliforms, E. coli, yeast and mould were detected. The powdered formulation that generates PAA in-situ was based on 70% w/w sodium percarbonate, mixed with 20% w/w TAED and mixed with 10% citric acid.
Treatment with Formula (Peracetic acid Generated In-Situ with a Wetting Agent):
1 ton of cleaned hemp seeds (2 million CFU per gram) were sanitized with a 0.4% concentration (4 kg of formula 18/18). Said formula 18/18 is powdered formulation is based on 40% sodium percarbonate, mixed with 20% TAED; mixed with 18% potassium silicate; mixed with 18% EDTA acid; and finally mixed with 4% Bioterge AS 90 surfactant. The 4 Kg were diluted in 40 L water and were mixed thoroughly for 10 minutes and then applied to treat 1 ton of hemp seed for 30 minutes, then the treated seeds were dried very well as per the grain conditioner process. The results showed a reduction in total bacterial count to 54,000 CFU per gram. These results were satisfactory and complied with the market standards. Coliforms, E. coli, yeast and mould were not detected.

Conclusions:

Based on the results shown above, there was noted a synergy between oxidizers (i.e. peracetic acid and hydrogen peroxide) and wetting agent (i.e. surfactant) in reducing the populations of human pathogens on edible seeds.

EXAMPLE 3

Determination of Contact-Time Efficacy of Powdered PAA Combined with Alcohol and a Wetting Agent

Objective: The objective of this study is to determine the effective contact-time of the sanitizing solutions (PAA with an alcohol and a wetting agent) sprayed on hemp seeds in controlling pathogens.
Protocol: 1 kg of hemp seeds per mix was treated with 50 ml of solution by applying small amounts at a time using a hand sprayer and mixing thoroughly in between. Batches were stored in 3.3 L containers at room temperature with lids on to avoid loss of moisture due to evaporation.
Solutions Used:

- Neo-Pure (5%), (50 g Neo Pure dissolved in 1 L water and mixed for 15 minutes)
- Neo-Pure / Ethanol (5% Neo Pure dissolved in 50% water/50% alcohol),
- Mock (H₂O)
  Samples were taken at the indicated time points and plated immediately with the exception of the +1 hr time point in the experiment of 8/25 (This sample was taken at +1 hr but stored at 4° C. o/n and plated the next morning).

Conclusions:

- Under lab conditions (room temperature: 20° C. to 27° C.) the efficacy of both Neo-Pure only and Neo-Pure+EtOH increased significantly with longer incubation times (≧24 hours)
- This effect was much more prominent at the beginning of the treatment with Neo-Pure only. However, it was noted that no significant regrowth of bacteria was observed within the first 48 hours post treatment if EtOH was present.
- Once seeds were treated with PAA+alcohol and/or wetting agent, the sanitizing solution continues to work for hours and reduce the population of bacteria. However, after 48 hrs, seeds had to be dried to reduce the moisture content below 10% in order to prevent regrowth of microorganisms. A moisture content below 10% is a usual standard of the industry to prevent a growth of microorganisms.
