Abstract

The invention discloses a composite film coating agent for retaining freshness of fresh flowers and method for performing film-coating freshness retaining on the fresh flowers. The composite film coating agent comprises the following components of polyvinyl alcohol, chitosan, citric acid, a surface active agent, natamycin, a plasticizer and water. The composite film coating agent for retaining the freshness of the fresh flowers is reasonable in formula, and all the components achieve a synergistic effect; when the composite film coating agent is coated on the surfaces of fresh cut flowers, the firmness of petals can be effectively improved, and the elasticity and the toughness of the cut flowers are obviously enhanced by 10-20 times as compared with non-film-coated fresh flowers; package, transportation and exhibition of the fresh flowers are facilitated; a uniform colorless and transparent thin film is formed on the surface of each fresh cut flower; the quality and the color of the cut flowers are increased, the natural glossiness of the cut flowers is kept, and the ornamental value of the cut flowers is increased; the respiratory action of the postharvest cut flowers can be alleviated; loss of water and generation of germs and pests are reduced; the vase life of the cut flowers is prolonged.

Description

Technical field [0001] The invention belongs to the technical field of fresh flowers preservation, and in particular relates to a composite film coating agent for fresh flowers preservation, and also relates to a fresh flower film preservation method using the composite film agent. Background technique [0002] China's flower planting area has reached 640,000 hectares. The common flowers mainly include rose, peonies, roses, carnations, lilies, osmanthus, pigeon flowers, nightflowers, and plum blossoms.
