Abstract: Barrier coating compositions, wash compositions, and other compositions for perishables and methods, systems, kits, and coated perishables relating thereto are provided. Fresh fruits and vegetables, in particular, can benefit from the teachings of the present disclosure. Preferred barrier coating compositions include an active hydrogen component that preferably includes one or more of a lipid, a polysaccharide, a polypeptide, or a combination thereof. In addition to providing active hydrogen groups, the active hydrogen component preferably functions as a binder and/or barrier component. The barrier coating compositions may include one or more materials to facilitate crosslinking of the resulting coating.

Abstract: Methods, kits, and treatment compositions for treating agricultural products to reduce or preventing wildfire smoke taint or other types of taint, including treated agricultural products, are provided. One or more treatment compositions effective in reducing or preventing wildfire smoke taint are preferably applied to agricultural products such as, for example, wine grapes prior to and/or during wildfire smoke exposure.

Abstract: Shelf-life extender compositions, kits, and methods are provided for use with live plant items such as, for example, rootless plant cuttings and plant liners. The shelf-life extender composition is preferably applied on at least a portion of the surfaces of a live plant item prior to shipping the treated live plant item.

Abstract: Methods and systems for selectively applying a treatment to a plant item is provided. The method may include conveying, in an industrial processing line, at least one plant item in the batch of plant items to a sensing region having one or more sensors, assessing, with the one or more sensors and a computing device, one or more properties of the at least one plant item associated with ripeness and/or another attribute, conveying the at least one plant item to a treatment region, determining a treatment to apply to the at least one plant item based on the assessed one or more properties; and applying, in the treatment region, the treatment to the at least one plant item.
