Title: Edible coating preparation which has fresh food deterioration-controlling function and promotes decrease in weight of container, packaging material or the like and reduction in distribution cost
Inventor: OHARA SABURO
IPC: A23L13/00
Filed: 2000-07-19
Abstract: PROBLEM TO BE SOLVED: To provide an edible coating preparation which can improve the gloss of a fresh food without changing the physical properties, taste and color of the fresh food and can easily control the decay and deterioration of the fresh food with a safe harmless low calorie ingredient. SOLUTION: This edible coating preparation comprises a powder agent obtained by adding a sucrose fatty acid ester, a monoglyceride, an antifungal agent, and an organic acid to water-soluble polymer pulluran as a main agent. The edible coating preparation is, if necessary, dissolved in an aqueous ethanol solution and then used for a dipping or spraying treatment. The edible coating preparation controls the air oxidation of the fresh food (strawberry, raw tuna to be eaten in the raw state), gives gloss to the surface of the food, and inhibits the proliferation of microorganisms to maintain the freshness. Consequently, since the loss of the fresh food in a distribution industry and the like can be decreased without deteriorating the color and taste of the fresh food, the edible coating preparation is useful for the good preservation of the foods. The edible coating preparation in the form of the powder agent enables to save labors for dissolution and further save the cost of a bottling work and the cost of bottles in a bottling process. The edible coating preparation can further reduce the cost of distribution due to the reduction in the weight of containers by the change of bottles into bags and can substantially un-necessitate a cost for recycling the containers. Since the dissolution of the edible coating preparation in a proper concentration can arbitrarily be carried out by a user, the edible coating preparation has improved usability.
