METHOD OF EXTRACTING SALT FROM PLANT MATTERBYNORTON, SAMUELHICKS, TANNERTITLEMETHOD OF EXTRACTING SALT FROM PLANT MATTER

[0001] This utility patent application claims benefit of United States Provisional Patent Application Serial Number 63 / 465,180 filed in the United States Patent and Trademark Office on May 9, 2023.BACKGROUND OF THE DISCLOSURE

[0002] Sodium chloride (NaCl) is one of the most abundant minerals and most commonly used food additives in the world. Sodium chloride can be found commercially in a variety of forms including, but not limited to: (i) common table salt; (ii) kosher salt; (iii) sea salt; (iv) iodized salt; and (v) Himalayan pink salt. Due to its antimicrobial properties, sodium (Na+) is predominantly used as a food preservative to increase the duration which food can be stored without spoiling, commonly known as making food more “shelf-stable.”

[0003] While sodium is commonly added to foods as a preservative, its prolific use in this way has made it increasingly difficult to source “low-sodium” foods. Thanks to preservatives and other dietary choices, sodium intake in the United States has historically exceeded recommended daily intake amounts. The overconsumption of sodium can lead to hypertension, kidney disease, stroke, and heart failure - the number one cause of death in the United States.

[0004] However, consumption of sodium is a necessary part of human diets, health, and wellbeing. Sodium comprises approximately half of the foundation of human nervous systems, is one of the most important regulators of blood pH levels, and is a powerful electrolyte that influences the activities of human renal systems. The recommended daily amount of sodium to be consumed by humans for disease reduction is 2,300 mg / day, while a minimum required amount for biological functions lies between 180 - 230 mg / day. Based on a study by the United States Department of Health and Human Services (HHS), the average daily consumption of sodium among all genders and ages between the years of 2003 and 2016 was 3,539 mg / day, a figure significantly exceeding that of the recommended daily amount.

[0005] A variety of salt alternatives exist on the market; however, these salt alternatives often sacrifice overall taste or lack versatility as an additive to achieve lower sodium levels in food products when compared to traditional salt additives. For example, potassium chloride(KC1), which is a common salt alternative that does not contain any amount of NaCl, maintains a marked bitter aftertaste. Additionally, “low-sodium” food options also exist on the market, but these low-sodium foods are often found to be less flavorful when compared to their traditional NaCl counterparts.

[0006] Known methods of food preservation via introduction of sodium chloride have a potential to result in adverse effects to human health, diet, and wellbeing. Further, “low- sodium” foods, those which either comprise reduced amounts of sodium or salt alternatives like potassium chloride, present one potential solution to the above-stated issue; however, these “low-sodium” food options are generally less flavorful and / or fail to function as versatile food additives when compared to traditional, salt-based methods.

[0007] Various industry practices exist for extraction of salt from plant matter. For instance, current ashing processes require intense heat and subject the plant matter to conditions ultimately detrimental to the resulting crystalline salt product. Lastly, processes used to dry the plant matter, such as centrifuging, are inadequate and often require additional fdtration and drying steps.

[0008] Accordingly, a need exists for a method of producing healthy, salt alternatives that maintain the flavorful characteristics of traditional sodium chloride additives while simultaneously reducing the sodium content of associated foods. Further, a need exists for a method of producing salt alternatives with proper salt content, controlled mineral content, and a reduction in input requirements to dry and produce resulting crystalline salt products.BRIEF SUMMARY OF THE DISCLOSURE

[0009] The present disclosure is directed in general to methods of producing healthy salt alternatives that maintain the flavorful characteristics of traditional sodium chloride additives while simultaneously reducing the sodium content of associated foods, producing controlled mineral contents, and efficiently drying plant matter to produce crystalline salt from plant matter. These methods are particularly beneficial in the production of crystalline salt products from salt-tolerant plants.

[0010] More specifically, various methods of extracting salt from plant matter are provided herein. In one aspect, a method of extracting salt from plant matter may include harvestinghalophyte Salicornia spp. plant matter; dehydrating Salicornia spp. plant matter; micronizing the dehydrated Salicornia spp. plant matter; mixing the micronized Salicornia spp. plant matter into a heated distilled water solution to produce an aqueous mixture; clarifying the aqueous mixture by filtration; and inducing salt crystallization of the aqueous mixture through evaporation.

The present subject matter thus includes any modifications and variations of the following examples as come within the scope of the appended claims and their equivalents.

[0026] Turning now to FIGURE 1, a flow chart shows exemplary steps of a method for extracting salt from plant matter broadly indicated by element number 100. More specifically, FIGURE 1 illustrates a process of converting halophyte Salicornia spp. to crystalized salt.

[0027] The method 100 of FIGURE 1 may first include harvesting halophyte Salicornia spp. plant matter as shown at step or stage 110. Harvesting of the halophyte Salicornia spp. may include hand harvesting, harvesting with hand-held tools, or machine harvesting.

[0028] The method 100 may next include dehydrating the Salicornia spp. plant matter to reduce moisture content as shown in step 120. Dehydrating harvested Salicornia spp. is necessary to remove excess moisture from the Salicornia spp. plant matter. Furthermore, a postharvest treatment of the Salicornia spp. is necessary to prevent fouling of a crystallized salt produced from the Salicornia spp. plant matter. Any damage to a surface or a structure of the Salicornia spp. may instigate an interaction of endogenous polyphenol oxidase (PPO), peroxidase, and / or other present enzymes within phenolics (collectively, “enzymes”) of the Salicornia spp. To prevent fouling, which may include browning, bitter taste, and displeasing odor of the crystallized salt, enzymatic activity must be inhibited. Inactivation of the enzymes may be achieved with a variety of methods including, but not limited to, blanching (i.e., thermal shocking), chemical denaturing (i.e., use of reducing agents, enzyme inhibitors, and chelating agents), electrical denaturing (i.e., pulse electric field processing), deoxygenation, or dehydration.

[0029] In one embodiment, Salicornia spp. is dehydrated inside a climate-controlled environment such as a structure that could be a grow tent. The climate-controlled grow tent is capable of maintaining a relatively stable temperature and moisture content of enclosed air. Further, the climate-controlled grow tent may also include a heating mechanism, such as a space heater, to assist with evaporation. In one aspect, the climate-controlled grow tent may include a unit measuring eight feet by eight feet (8 ft. x 8 ft.) capable of removing up to ninety- five percent (95%) of moisture contained within the Salicornia spp. plant matter. Further, the climate-controlled grow tent may be capable of reducing exposure of the Salicornia spp. plant matter to compromising environmental conditions including extreme temperatures, biological contaminants, and excess humidity.

[0030] Other methods of dehydrating the Salicornia spp. plant matter may include freeze drying and solar evaporation. Additionally or alternatively, methods of dehydrating the Salicornia spp. plant matter may include oven drying, rotary drum drying, fluidized bed drying, and conveyor drying.

[0031] The method 100 of FIGURE 1 may also include micronizing the dehydrated Salicornia spp. into a powder as shown in step 130. Micronization reduces an average diameter of a particle of a solid material. More specifically, micronization is used to reduce the average diameter of particles to a micron-size level, that is, a size on the order of magnitude of one- millionth of a meter.

[0032] Micronization of the dehydrated Salicornia spp. may be accomplished via mechanical milling or grinding. In one aspect, micronization of the dehydrated Salicornia spp. is achieved with a blender mechanism such as a blender or mixer. In an alternate embodiment, micronization of the dehydrated Salicornia spp. may be accomplished with a grinder, mortar and pestle, hammer mill, or air mill. Further, micronization of the dehydrated Salicornia spp. may also be accomplished by introducing supercritical fluids to induce a state of supersaturation of the dehydrated Salicornia spp. to result in a precipitation of individual particles.

[0033] Micronization of the dehydrated Salicornia spp. is undertaken to separate mineral salts (i.e., resultant crystallized salt) contained within the dehydrated Salicornia spp. from a remaining plant matter biomass. Further, micronization of the dehydrated Salicornia spp. before a process of rehydrating promotes a more efficient extraction of intracellular minerals by mechanically degrading cells of the dehydrated Salicornia spp. plant matter (i.e., biomass.)

[0034] With continued reference to FIGURE 1, the method 100 may next include mixing the micronized Salicornia spp. into a heated distilled water solution as shown in step 140. After the dehydrated Salicornia spp. is micronized into a fine particulate or powder to separate the mineral salts from the remaining plant matter biomass, the micronized Salicornia spp. is mixed into the distilled water solution. In one aspect, a temperature of the distilled water solution is approximately one hundred and thirty degrees Fahrenheit (130°F) to one hundred and fifty degrees Fahrenheit (150°F), more particularly, one hundred and forty degrees Fahrenheit (140°F). A ratio of mixing the micronized Salicornia spp. into the distilled water solution is approximately at a ratio of 0.75: 1 to 1.5: 1, preferably 1: 1, that is, one-part distilled water solution to one-part original wet biomass of the Salicornia spp. plant matter by weight to produce an aqueous Salicornia spp. solution (i.e., heated brine solution). A volume of distilledwater is maintained to maximize a solubility of the micronized Salicornia spp. in the resultant heated brine solution.

[0035] A process of adding the micronized Salicornia spp. to the distilled water solution, known as rehydrating, can reactivate enzymatic activity and instigate a degradation of present phenolic compounds. Therefore, the distilled water solution is heated before the micronized Salicornia spp. is introduced and the resultant heated brine solution is cooled post-mixing - a process known as pasteurization. The resultant brine solution may be pasteurized by heating the brine solution in a heating vessel. In one aspect, the heating vessel may include a stainless steel kettle. Furthermore, the heating vessel may be heated with natural gas. In an alternate embodiment, pasteurization may be accomplished via vat (i.e., batch) pasteurization or High Temperature Short Time (HTST) pasteurization technologies.

[0036] After the resultant brine solution, that is, an aqueous solution of Salicornia spp. and distilled water, is heated, the brine solution may be cooled. After the micronized Salicornia spp. is thoroughly mixed into the distilled water solution, excess biomass is removed and collected by pouring the heated brine solution through a mesh-screen bag, for instance, although any screening mechanism may be employed. The mesh-screen bag retains a content of rehydrated excess biomass. The rehydrated excess biomass may then be added to a mechanical device, such as a juicer, to collect any remaining brine solution. The remaining brine solution removed from the rehydrated excess biomass may then be returned to the heated brine solution. The excess biomass, (i.e., “bagasse”) may then be removed from the mechanical device, dehydrated, and stored for further use.

[0037] Cooling of the heated brine solution may be accomplished by placing the heated brine solution in a refrigerated space. In one aspect, the heated brine solution may be placed in a walk-in refrigerator. At this stage in method 100, a resultant and cooled brine solution may be referred to as an aqueous Salicornia spp. mixture.

[0038] The exemplary method 100 of FIGURE 1 may further include clarifying the aqueous Salicornia spp. mixture by fdtration as shown in step 150. After the brine solution is pasteurized and cooled, the brine solution is fdtered to remove excess plant matter and clarify the remaining brine. In one aspect, the remaining brine is filtered to a size of approximately five (5) microns.

[0039] Filtering the brine solution may be accomplished, for example, utilizing a dead-end canister filtration system. The dead-end canister filtration system may include a series of micron filters arranged in such a way that the brine solution passes through the series of micron filters that gradually reduce in size. A gradual reduction in size of the series of micron filters prevents clogging due to organic matter buildup. In one aspect, at least one of the series of micron filters may include a carbon filter to ensure separation of potentially toxic materials from the filtered brine solution. In an alternate embodiment, filtration of the brine solution may be accomplished with any dead-end filtration system or cross-flow filtration system.

[0040] The method 100 may further include inducing salt crystallization of the filtered, aqueous Salicornia spp. mixture through evaporation as shown in step 160 in FIGURE 1. Once the pasteurized aqueous Salicornia spp. mixture is filtered, the aqueous Salicornia spp. mixture is separated into smaller volumes. In one aspect, each volume of the aqueous Salicornia spp. mixture may be organized on food-grade trays. Each volume of the aqueous Salicornia Spp. mixture is then left to undergo a process of evaporation. Evaporation permits moisture within the aqueous Salicornia Spp. mixture to be removed to promote salt crystallization. In one aspect, the process of evaporation takes approximately twenty-four (24) to approximately forty-eight (48) hours. Once the process of evaporation is complete, dry salt crystals remain on the food-grade trays devoid of moisture content. The salt crystals are then removed from the food-grade trays and collected in food-safe containers.

[0041] In a further aspect, the process of evaporation may utilize a climate-controlled grow tent approximately eight feet by four feet (8 ft. x 4 ft.) in size. The climate-controlled grow tent is similar to that of the previously discussed climate-controlled grow tent used to dehydrate the original biomass solution. Further, the climate-controlled grow tent used in the process of evaporation may include an average relative humidity of twenty percent (20%) and an ambient temperature of between one hundred and one degrees Fahrenheit (101°F) and one hundred and four degrees Fahrenheit (104°F), more particularly, one hundred and two point two degrees Fahrenheit (102.2°F). The period of time to evaporate moisture content from the aqueous Salicornia Spp. mixture determines a size and a shape of the resulting crystallized salt formed during the evaporation process. Rapid evaporation may lead to undefined, smaller salt crystals, whereas slower evaporation may lead to larger, cuboidal salt crystals. In an alternateembodiment, other methods of evaporation may include spray drying, drum drying, freeze drying, fluid bed drying, dielectric drying, and cavitation.
