[Technical Field]

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS This application claims the benefit of priority to U.S. Application No. 63 / 427,758, filed November 23, 2022, which is incorporated by reference herein in its entirety.

[0002] Technical Field FIELD OF THE DISCLOSURE The present disclosure relates to coatings for agricultural products. [Background technology]

[0003] background Common agricultural products are susceptible to deterioration and decomposition (i.e., spoilage) when exposed to the environment. Such agricultural products can include, for example, eggs, fruits, vegetables, produce, seeds, nuts, flowers, and / or whole plants (including their processed and semi-processed forms). Non-agricultural products (e.g., vitamins, candy, etc.) are also susceptible to deterioration when exposed to the ambient environment. Deterioration of agricultural products can occur through abiotic means as a result of evaporative water loss from the exterior surface of the agricultural product into the atmosphere, and / or oxidation by oxygen diffusing into the agricultural product from the environment, and / or mechanical damage to the surface, and / or light-induced decomposition (i.e., photodegradation). Additionally, biotic stressors, such as bacteria, fungi, viruses, and / or pests, can also infest and decompose agricultural products.

[0004] Traditional approaches to preventing deterioration, maintaining quality, and extending the shelf life of agricultural produce include refrigeration and / or specialized packaging. Refrigeration requires capital-intensive equipment, requires constant energy consumption, and, if not carefully controlled, can cause product spoilage or quality loss and must be actively managed. Additionally, interruptions in the temperature-controlled supply chain can negate the benefits of refrigeration. Specialized packaging also requires expensive equipment, consumes packaging materials, increases transportation costs, and can require active management. Despite the potential benefits of refrigeration and specialized packaging, handling and transportation of agricultural produce can cause surface abrasions or bruises, which are unsightly to consumers and can serve as entry points for bacteria and fungi. Furthermore, the expenses associated with such approaches can increase the cost of agricultural produce. Summary of the Invention [Means for solving the problem]

The term "or" is used to refer to a non-exclusive "or" unless otherwise noted. The statement "at least one of A and B" has the same meaning as "A, B, or A and B." Additionally, it should be understood that phrases or terms utilized in this disclosure, unless otherwise defined, are for descriptive purposes only and not for purposes of limitation. Any use of section headings is intended to aid in the reading of the document and should not be construed as limiting. Information associated with a section heading may occur within or outside the particular section.

[0116] Values ​​expressed in range format should be interpreted in an open manner and should be construed to include not only the numerical values ​​explicitly recited as the limits of the range, but also all individual numerical values ​​or subranges subsumed within the range, as if each numerical value and subrange were explicitly recited. For example, a range such as "about 0.1% to about 5%" or "about 0.1% to 5%" should be interpreted to include not only about 0.1% to about 5%, but also individual values ​​(e.g., 1%, 2%, 3%, and 4%) and subranges (e.g., 0.1% to 0.5%, 1.1% to 2.2%, 3.3% to 4.4%) within the recited range. The statement "about X to Y" has the same meaning as "about X to about Y" unless otherwise indicated. Similarly, the statement "about X, Y, or about Z" has the same meaning as "about X, about Y, or about Z" unless otherwise indicated.

[0117] As used herein, the term "about" allows for a variation of a value or range to within 10% of the stated value or limit of a stated range.

[0118] In the methods described herein, acts may be performed in any order unless a temporal or operational order is explicitly recited. Furthermore, specified acts may be performed simultaneously unless the claim language clearly dictates that they be performed separately. For example, a claimed act of performing X and a claimed act of performing Y may be performed simultaneously in a single operation, and the resulting process would fall within the literal scope of the claimed process.

[0119] As used herein, the term "monoglyceride" refers to the condensation product of one glycerol molecule and one fatty acid, i.e., a glycerol group linked to one fatty acid via an ester bond. Monoglycerides can be, but do not necessarily have to be, derived from a condensation reaction. For example, monoglycerides can be obtained by an esterification reaction between glycerol and a fatty acid, such as by transesterification of a triglyceride with glycerol (glycerolysis). Monoglycerides are also sometimes referred to as glyceryl monoalkanoates. When the glycerol group is linked to the ester bond at the 1-position (e.g., as in 2,3-dihydroxypropan-1-yl octadecanoate), the monoglyceride may be referred to as a 1-monoglyceride or a 1-glyceryl alkanoate (e.g., as in 1-glyceryl octadecanoate). When the glycerol group is attached to the ester bond at the 2-position (e.g., as in 1,3-dihydroxypropan-2-yl hexadecanoate), the monoglyceride may be referred to as a 2-monoglyceride or a 2-glyceryl alkanoate (e.g., as in 2-glyceryl hexadecanoate). The glycerol group of the monoglyceride may be unsubstituted (e.g., as in 2,3-dihydroxypropan-1-yl alkanoate) or may be further substituted with one or more groups other than fatty acids (e.g., as in 1,3-dialkoxypropan-2-yl alkanoate).

[0120] The term "alkyl ester" used in reference to fatty acids refers to the condensation product of an alkanol and a fatty acid, i.e., an alkyl group attached to one fatty acid via an ester bond. Alkyl esters can be, but do not necessarily have to be, derived from a condensation reaction. For example, alkyl esters can be obtained by esterification between an alkanol and a fatty acid, or by transesterification of monoglycerides, triglycerides, etc. Alkyl esters are also sometimes called alkyl alkanoates. For example, the ethyl ester of hexadecanoic acid is sometimes called ethylhexadecanoate.

[0121] As used herein, the term "fatty acid" refers to a carboxylic acid having an aliphatic side chain. Fatty acids can be naturally occurring or non-naturally occurring and can contain branched or unbranched (e.g., straight-chain), substituted or unsubstituted, saturated or unsaturated side chains.

[0122] As used herein, the term "side chain" refers to the aliphatic portion of a fatty acid, or a portion thereof. Unless otherwise indicated, the side chain of a given fatty acid includes the carbon of the carboxylic acid group. For example, dodecanoic acid has a straight-chain saturated C 12 side chains, R H -C(O)OH (where R H is the saturated C 11 Side chains other than fatty acids (e.g., esters or amides) can be present in the compound and can be, but need not be, derived from fatty acids. For example, dodecanamide can be described as an amide of a fatty acid, regardless of whether the compound is actually derived from dodecanoic acid.

[0123] When certain features of the compounds described herein are disclosed as groups or ranges, such disclosure includes any and all individual subcombinations of the members of such groups and ranges. For example, the term "C1-C6 alkyl" includes (without limitation) methyl, ethyl, C3 alkyl, C4 alkyl, C5 alkyl, and C6 alkyl.

[0124] As used herein, the term "n-membered" (where n is an integer) generally describes the number of ring-forming atoms in a moiety where n is the number of ring-forming atoms. For example, piperidinyl is an example of a 6-membered heterocycloalkyl ring, and 1,2,3,4-tetrahydro-naphthalene is an example of a 10-membered cycloalkyl group.

[0125] As used herein, the term "substituted" means that an atom or group of atoms is formally replaced with hydrogen as a "substituent" attached to another group. "Substituted" refers to any level of substitution, for example, mono-, di-, tri-, tetra-, or penta-substitution, unless otherwise specified, where such substitution is permitted. Substituents are independently selected, and substitution may occur at any chemically available position. Substitution at a given atom is limited by valence. Substitution at a given atom results in a chemically stable molecule. The phrase "optionally substituted" means unsubstituted or substituted. A single divalent substituent, for example, oxo, can replace two hydrogen atoms.

[0126] As used herein, "C n ~C m The term "(where n and m are integers and indicate the number of carbons)" denotes a range that includes the endpoints. Examples include C1-C4, C1-C6, etc.

[0127] As used herein, the term "alkyl" refers to a saturated hydrocarbon group which may be straight-chained or branched. n ~C mThe term "alkyl" refers to an alkyl group having n to m carbon atoms.

Examples of alkyl moieties include, but are not limited to, chemical groups such as methyl, ethyl, n-propyl, isopropyl, n-butyl, tert-butyl, isobutyl, sec-butyl; higher homologs such as 2-methyl-1-butyl, n-pentyl, 3-pentyl, n-hexyl, 1,2,2-trimethylpropyl, and the like.

[0128] As used herein, the term "alkenyl" refers to a straight-chain or branched hydrocarbon group corresponding to an alkyl group having one or more carbon-carbon double bonds. An alkenyl group formally corresponds to an alkene in which one C-H bond is replaced by the point of attachment of the alkenyl group to the remainder of the compound. n ~C m The term "alkenyl" refers to an alkenyl group having n to m carbons. Exemplary alkenyl groups include, but are not limited to, ethenyl, n-propenyl, isopropenyl, n-butenyl, sec-butenyl, and the like.

[0194] Example

[0195] Example 1 Crystallinity of lecithin-containing mixtures

[0196] Coating agents A to E having the compositions shown in Table 1 were prepared.

[0197] [Table 1]

[0198] Mixtures 1 to 6 of coating agents A to E dispersed in water at the concentrations shown in Table 2 were prepared.

[0199] [Table 2]

[0200] An 8-12 mg sample of each mixture was placed on a sealed sample pan and analyzed using a differential scanning calorimeter (DSC). The samples were subjected to two heating and cooling cycles: heating cycle 1: 20°C → 70-80°C, rate: 10°C / min; cooling cycle 1: 70-80°C → 10°C, rate: -10°C / min; heating cycle 2: 10°C → 70-80°C, rate: 10°C / min; cooling cycle 2: 70-80°C → 10°C, rate: -10°C / min. The results of the second cooling cycle were identical to those of the first. The DSC results for mixtures 1-5 are shown in Figure 1, which indicated that the degree of crystallinity increased as the lecithin content decreased. Figure 2 compares the DSC curves for mixtures 1 and 6 and shows no correlation between the crystallization peak and the concentration present.

[0201] The mass loss coefficients (MLF; the ratio of the average mass loss rate of untreated produce to the average mass loss rate of coated produce over a given period of time) of produce coated with each of Mixes 1-5 were predicted using a model based on the space-filling mixture design of experiments (DoE) in Example 3 below, and then plotted against the respective crystallization enthalpies (calculated by integrating the peaks shown in Figure 1). The resulting graph is shown in Figure 3. A linear fit of the points (y = 0.2223x + 1.0962; R 2 =0.9525), demonstrating a correlation between barrier performance and coating crystallinity.

[0202] Example 2 Stability / compatibility mapping of lecithin-containing formulations

[0203] A space-filling mixture design of experiments (DoE) was conducted on coatings containing combinations of sunflower lecithin (mass fractions 0-1), glyceryl monostearate (mass fractions 0-1), and glyceryl monolaurate (mass fractions 0-1) dispersed in water (50 g / L). The initial design space is shown in Figure 4. Each formulation shown in Figure 4 (filled circles) was tested for miscibility and stability.

[0204] The resulting profiles for the miscibility (1 = miscible; 0 = unmiscible) and stability (1 = stable for more than 1 day; 0 = stable for less than 1 day) of the colloidal dispersions as a function of the mass fraction of lecithin, glycerol monostearate, and glycerol monolaurate are shown in Figures 5 and 6, respectively. The results showed that a lecithin content greater than 10 wt% and a glycerol monolaurate content less than 15 wt% resulted in acceptable miscibility and stability.

[0205] Example 3 Performance mapping of lecithin-containing compositions

[0206] A space-filling mixture Design of Experiments (DoE) was conducted on coatings formed from coatings containing combinations of sunflower lecithin (mass fractions 0-1), glyceryl monostearate (mass fractions 0-0.8), and glyceryl monolaurate (mass fractions 0-0.15) dispersed in water (50 g / L). The initial design space is shown in Figure 7. Cherries were coated with each formulation (block dot) shown in Figure 7 by dipping into a bowl containing the colloidal dispersion and then allowed to dry at room temperature. The coated cherries were then tested to determine the mass loss coefficient (averaged over 100 cherries per formulation) and visually evaluated to determine the retention score (averaged over 40 cherries per formulation). Examples of coated cherries with retention scores of 0, 0.5, 1, and 2 are shown in Figures 8A, 8B, 8C, and 8D, respectively. A residue score of less than 0.5 indicated that the residue was barely noticeable or not present.

[0207] Triangular plots of the mass loss factor and residue score across the design space are shown in Figures 9 and 10, respectively. As shown in Figure 11, (A) a coating containing 12.1 wt% lecithin, 78.1 wt% glycerol monostearate, and 9.8 wt% glycerol monolaurate, and (B) a coating containing 54.1 wt% lecithin, 39.1 wt% glycerol monostearate, and 6.7 wt% glycerol monolaurate each had acceptable mass loss factors (1.79 and 1.33, respectively) and produced coatings with less visible residue compared to (C) a comparative coating containing 95 wt% glycerol monostearate and 5 wt% sodium stearate (mass loss factor of 1.91).

[0208] Coating bananas

[0209] Coating agents F to I having the compositions shown in Table 3 were prepared.

[0210] [Table 3]

[0211] Mixtures 7-10 were prepared of coating agents F-H dispersed in water at the concentrations shown in Table 4. For each of Mixtures 7-10, bananas were coated by dipping them into a bowl containing the mixture and then allowed to dry at room temperature. The coated bananas were visually inspected for peeling and residue formation.

[0212] [Table 4]

[0213] Images of bananas coated with Mixtures 7, 9, and 10 are shown in Figures 12A, 12B, and 12C, respectively. As shown in Figures 12A-C, no delamination was observed for bananas coated with the lecithin-containing formulations (delamination is indicated by the white arrow in Figure 12A).

[0214] Images of bananas coated with Blends 8 and 10 are shown in Figures 13A and 13B, respectively. As shown in Figures 13A and 13B, less residue formation was observed for the coatings formed from the lecithin-containing formulations.

[0215] Coating cherry tomatoes

[0216] Coating agents J to R having the compositions shown in Tables 5 and 6 were prepared.

[0217] [Table 5]

[0218] [Table 6]

[0219] Mixtures 11-19 were prepared of Coating Agents J-R dispersed in water at the concentrations shown in Table 7. Mixture 13 did not emulsify properly. Samples of each mixture were analyzed using a differential scanning calorimeter (DSC) following the procedure described in Example 1 above. DSC results for Mixtures 11-19 showed no difference in crystallinity due to the inclusion of alkyl esters, with monoglyceride to alkyl ester weight ratios ranging from 9:1 to approximately 2:1. In a rheometer (TA instruments Discovery HR-3), the mixtures were run in a double-walled concentric cylinder (inner bob diameter 32.01 mm; outer bob diameter 35.01 mm) using a shear flow ramp (20°C; 0.0 immersion time; 60-second duration; shear rate range 1.74-500 s). -1) was also used to determine the viscosities of Mixtures 11-19. The results, shown in Figure 14, indicated that the change in viscosity due to the inclusion of alkyl esters was only minimal at weight ratios of monoglyceride to alkyl esters from 9:1 to approximately 2:1. At a weight ratio of approximately 2:1, the mixtures had 30-40 wt% higher viscosities compared to the corresponding mixtures without alkyl esters.

[0220] For each of mixtures 11-19, a group of 80 cherry tomatoes was coated by dipping them into a bowl of the mixture and then allowed to dry at room temperature. The mass loss of the coated cherry tomatoes and a control group of uncoated cherry tomatoes was then measured on a flat tray.

[0221] [Table 7]

[0222] Images of cherry tomatoes one day after coating with Mixtures 11 and 16 are shown in Figures 15A and 15B, respectively. Images of untreated cherry tomatoes and cherry tomatoes coated with Mixtures 11, 14, 16, 17, and 19 after 14 days of storage at ambient temperature are shown in Figures 16A, 16B, 16C, 16D, 16E, and 16F, respectively. As demonstrated in Table 7, Figures 14, 15A, and 15B, and Figures 16A-16F, lecithin-containing coatings further comprising alkyl esters can provide improved barrier properties without significantly affecting the properties of the coating mixture, including residue formation.
