Description

一种防褐变果蔬加工设备Anti-browning fruit and vegetable processing equipment 技术领域technical field
本发明属于食品加工技术领域，涉及一种果蔬加工设备，特别是涉及一种防褐变果蔬加工设备。The invention belongs to the technical field of food processing, and relates to fruit and vegetable processing equipment, in particular to anti-browning fruit and vegetable processing equipment.
背景技术Background technique
对于鲜果蔬，现有的加工工艺，由于其工艺本身的原因或者添加多种辅料，破坏了鲜果蔬本身具有的药食价值，终端产品的营养成分大大降低。干制是果蔬加工的重要手段之一，目前冷冻干燥可较好地保持鲜果蔬的色泽，但因其加工周期长，能耗大，经济成本高，产品易吸潮等问题，使得该加工方式难以进行工业化生产。现有果蔬干加工过程中，常常出现果肉变色，从而影响果蔬干成品的口感。果肉变色的原因主要是酶促褐变，影响酶促褐变的必备条件是多酚类底物、多酚氧化酶和氧气，三者缺一不可。然而实际中去除多酚类物质方法来控制褐变并不适用。For fresh fruits and vegetables, the existing processing technology, due to the process itself or adding a variety of auxiliary materials, destroys the medicinal and food value of fresh fruits and vegetables, and the nutritional content of the end product is greatly reduced. Drying is one of the important means of fruit and vegetable processing. At present, freeze-drying can better maintain the color of fresh fruits and vegetables. Difficult to carry out industrial production. During the existing dried fruits and vegetables processing process, discoloration of pulp often occurs, thereby affecting the mouthfeel of dried fruits and vegetables. The main reason for pulp discoloration is enzymatic browning, and the necessary conditions for affecting enzymatic browning are polyphenolic substrates, polyphenol oxidase and oxygen, all of which are indispensable. However, the method of removing polyphenols to control browning is not applicable in practice.
此外，现有的果蔬干加工设备结构复杂，尤其在不同步骤环节，所需环境条件不同，这便需要每个步骤环节分别在一特定容器或设备内完成，不仅增加了设备的占用和使用成本，而且，由于果蔬干往往批量生产，多容器的使用也给果蔬干的转移带来了难题。In addition, the existing dried fruit and vegetable processing equipment has a complex structure, especially in different steps, which require different environmental conditions, which requires each step to be completed in a specific container or equipment, which not only increases the occupation and use costs of the equipment Moreover, since dried fruits and vegetables are often produced in batches, the use of multiple containers also brings difficulties to the transfer of dried fruits and vegetables.
