Description
[Technical Field]
[0001] CROSS-REFERENCE TO RELATED APPLICATIONS This application claims the benefit of priority to U.S. Application No. 63 / 427,753, 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]

While the disclosed subject matter will be described in conjunction with the enumerated claims, it will be understood that the illustrated subject matter is not intended to limit the claims to the disclosed subject matter.
[0098] definition
[0099] The terms "a," "an," and "the" are used herein to include one or more than one, unless the context clearly dictates otherwise. 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.
[0100] 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.
[0101] 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.
[0102] 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.
[0103] 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).
[0104] 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.
[0105] 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.
[0106] The term "salt" as used in connection with the disclosed compounds (e.g., fatty acids) refers to derivatives of the compounds in which the parent compound has been modified by converting an acid or base moiety into its salt form. Examples of such salts include, but are not limited to, inorganic or organic acid salts of basic residues such as amines, inorganic (e.g., alkali) or organic salts of acidic residues such as carboxylic acids, etc.

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.
[0110] 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.

[0171] Example
[0172] Example 1 Coated apples
[0173] Coatings A and B having the compositions shown in Table 1 were prepared.
[0174] [Table 1]
[0175] Mixtures 1 and 2 were prepared of coating agents A and B dispersed in water at the concentrations shown in Table 2. For each of Mixtures 1 and 2, apples were coated by dipping them into a bowl of the mixture and then dried in a heated tunnel at 50-60°C (dwell time 90-100 seconds). The mass loss of the coated apples and a control group of uncoated apples was then measured under ambient conditions. The results are shown in Table 2.
[0176] [Table 2]
[0177] As shown in Table 2, coatings formed from coatings containing beeswax reduced mass loss from produce.
[0178] Example 2 coated avocado
[0179] Coatings C and D were prepared having the compositions shown in Table 3.
[0180] [Table 3]
[0181] Mixtures 3 and 4 were prepared of coating agents C and D dispersed in water at the concentrations shown in Table 4. For each of Mixtures 3 and 4, avocados were coated by dipping them into a bowl of the mixture and then dried in a heated tunnel at approximately 70°C (dwell time 90-100 seconds). The coated avocados were evaluated under ambient conditions.
[0182] [Table 4]
[0183] An image of an avocado coated with Mixture 3 is shown in Figure 1A, and an image of an avocado coated with Mixture 4 is shown in Figure 1B. As shown in Figures 1A and 1B, the wax-containing coating with monoglyceride produced a coating with improved uniformity and higher gloss compared to the wax-containing coating without monoglyceride.
[0184] Example 3 Emulsion evaluation
[0185] Coating agents E to G having the compositions shown in Table 5 were prepared.
[0186] [Table 5]
[0187] Mixtures 5-7 were prepared of coating agents E-G dispersed in water at the concentrations shown in Table 6. Each of Mixtures 5-7 was subjected to successive filtrations (11 μm to 0.2 μm) and then freeze-dried to determine the percentage of emulsified solids present in each mixture after filtration. The results are shown in Table 6.
[0188] [Table 6]
[0189] As shown in Table 6, the wax-containing coatings containing fatty acid salts formed improved emulsions compared to the wax-containing coatings without fatty acid salts.
[0190] Example 4 Performance mapping of wax-containing compositions
[0191] A Scheffe ternary mixture design of experiments (DoE) was conducted on coatings formed from coatings containing combinations of beeswax (mass fractions 0-1), glyceryl monostearate (mass fractions 0-0.5), and sodium stearate (mass fractions 0.025-0.2) dispersed in water (30 g / L). The initial design space is shown in Figure 2. Colloidal dispersions (filled circles) of each composition shown in Figure 2 were visually inspected for phase separation. The resulting profile of phase separation (1 = phase separation; 0 = no phase separation) for the colloidal dispersions is shown in Figure 3 as a function of the mass fractions of beeswax, glycerol monostearate, and sodium stearate.
[0192] Approximately 0.6 mL of each colloidal dispersion was coated onto a glass slide, which was then dried overnight in an oven at approximately 40°C. After drying, the gloss level of each coated slide was measured twice using a handheld gloss meter (Horiba) rotated 90° between measurements. Generally, levels up to approximately 30 were considered low gloss, levels greater than approximately 30 to approximately 40 were considered medium gloss, and levels greater than approximately 40 were considered high gloss. A triangular graph of gloss levels across the design space is shown in Figure 4. Figures 5A and 5B show low gloss coatings formed from a coating containing 91.2 wt% beeswax and 8.8 wt% sodium stearate and a coating containing 75.3 wt% beeswax, 10 wt% glycerol monostearate, and 14.8 wt% sodium stearate, respectively. Figure 5C shows a medium gloss coating formed from 63.4 wt% beeswax, 30 wt% glycerol monostearate, and 6.6 wt% sodium stearate. Figure 5D shows a high gloss coating formed from 44.5 wt% beeswax, 40 wt% glycerol monostearate, and 15.5 wt% sodium stearate. As shown in Figure 4 and Figures 5A-5D, different relative amounts of wax, monoglyceride, and fatty acid salt produced coatings with different gloss levels.
[0193] Example 5 coated avocado
[0194] Coating agents H to N having the compositions shown in Tables 7 and 8 were prepared.
[0195] [Table 7]
[0196] [Table 8]
[0197] Mixtures 8-14 were prepared of coating agents H-M dispersed in water at the concentrations shown in Table 9. For each of Mixtures 8-14, avocados were coated by dipping them into a bowl of the mixture and then dried in a heated tunnel at approximately 70°C (dwell time 90-100 seconds). The mass loss of the coated avocados and a control group of uncoated avocados was then measured at ambient conditions. The results are shown in Table 9.
[0198] [Table 9]
[0199] Figure 6 compares an untreated avocado (left) with an avocado coated with Mixture 8 (right). As shown in Figure 6, the coated avocado had a higher gloss level compared to the untreated avocado. Figure 7 compares an avocado coated with Mixture 11 (left) with an avocado coated with Mixture 8 (right). As shown in Figure 7, the avocado coated with Mixture 11 had a lower gloss level compared to the avocado coated with Mixture 8. Figure 8 compares an avocado coated with Mixture 13 (left) with an avocado coated with Mixture 8 (right). As shown in Figure 8, the avocado coated with Mixture 11 had a significantly lower gloss level compared to the avocado coated with Mixture 8. The results in Figures 6-8 and Table 8 show that the coatings produced coatings with similar and acceptable barrier properties, although at different gloss levels (e.g., from high gloss with Coating H to low gloss with Coating M).
[0200] Scanning electron microscopy (SEM) was used to image the surfaces of untreated avocados and avocados coated with Mixtures 8, 12, and 14. The results are shown in Figure 9 (Everhart-Thornley detector (ETD); high voltage (HV) 5.00 kV; spot 4.0; magnification 500x; working distance (WD) 3.8 mm; horizontal field width (HFW) 254 μm; tilt 0°), Figure 10 (ETD; HV 3.00 kV; spot 2.0; magnification 500x; WD 8.4 mm; HFW 254 μm; tilt 0°), Figure 11 (ETD; HV 3.00 kV; spot 2.0; magnification 650x; WD 14.8 mm; HFW 195 μm; tilt 0°), and Figure 12 (ETD; HV 3.00 kV; spot 2.0; magnification 500x; WD 8.5 mm; HFW 254 μm; tilt 0°), respectively. As shown in Figures 9-12, the coatings formed from the coatings containing beeswax were relatively smooth compared to the coatings from the coatings without beeswax and compared to the scaly surface of the untreated avocado.
