  Described herein are formulations and methods of reducing spoilage in harvested produce by reducing the rate of water or mass loss, thereby resulting in high quality produce with lower rates of spoilage. The present disclosure provides coatings and methods of coating produce to prevent moisture loss from produce during storage and shipment of the produce. This in turn allows the produce to be shipped and stored at lower relative humidity (e.g., lower than industry standards for shipment and storage, or lower than about 90% relative humidity), which can help delay the growth of biotic stressors such as fungi, bacteria, viruses, and/or pests.

  本文描述了一种减少收获农产品变质的配方和方法，通过减少水分或质量的流失速率，从而获得质量高、变质率低的农产品。本文提供了覆盖物和覆盖农产品的方法，以防止农产品在储存和运输过程中失去水分。这反过来允许农产品在较低的相对湿度下运输和储存（例如低于行业运输和储存标准或低于约90%的相对湿度），这可以延迟生物胁迫因素（如真菌、细菌、病毒和/或害虫）的生长。

  An elastomer is molded by a reaction injection molding of polyurethane resins, polyurea resins, polyurethane/urea resins and polyurea/amide resins in the presence of an internal release agent which is a polyester condensate of a saturated or unsaturated fatty acid having a hydroxy group produced by transesterification or a molecular end-aminated or iminated polyester condensate. The elastomer has a good mold releasing property and a good coating property.

  The present invention relates to a process for the microbial in-chain hydroxylation of C12 to C16 fatty acids, alcohols and alkanes at position ω-7, the process including the use of a microorganism expressing a cytochrome P450 monooxygenase CYP505E3 or related fungal cytochrome P450 monooxygenases sharing at least 70% amino acid identity in the production of a hydroxylated product or secondary product. The present invention further relates to a process for the preparation of lactones, esters and polymers by hydroxylation of the corresponding fatty acids, fatty alcohols and alkane precursors by a recombinant cytochrome P450 monooxygenase CYP505E3 or related fungal cytochrome P450 monooxygenases sharing at least 70% amino acid identity.
