Formula of composite color fixative for fruits, vegetables and fruit and vegetable products and application method thereof

Abstract

The invention relates to a formula of a composite color fixative for fruits, vegetables and fruit and vegetable products and an application method thereof, which belong to the technical field of foodadditives. Disodium stannous citrate, citric acid and vitamin C are taken as raw materials, the novel formula of the composite color fixative for the fruits, the vegetables and the fruit and vegetableproducts is developed, the composite color fixation is characterized by safety, economy and high efficiency and can safely and effectively replace a sulfur-containing color fixative, so that the composite color fixative can be applied in the short-term preservation of the fresh fruits and the vegetables, and the pretreatment stage of the fresh-cut fruit and vegetable products and the deep processing products of the fruits and the vegetables for carrying out color fixation for further protecting the original color-luster of the fruits, the vegetables and the fruit and vegetable products.

Description

technical field [0001] The invention provides a formula and an application method of a compound color-protecting agent for fruits, vegetables and fruit and vegetable products, belonging to the technical field of food additives. technical background [0002] Fruits and vegetables are very prone to browning during their processing and storage, resulting in poor product color and affecting product quality. For example, quick-frozen or dried fruit and vegetable blocks, fruit and vegetable juices, fruit and vegetable beverages, canned fruits and vegetables, and preserved fruits are prone to browning. Browning of fruit and vegetable processing and storage products not only affects the appearance value of the product, but more importantly, the original flavor, nutritional value and physiological activity of the fruit and vegetable will also be greatly affected, and even lose the commodity value. For this reason, people have carried out many in-depth researches on the browning prin...
