Process for producing dried onion through dewatering

Abstract

The invention relates to a dried onion producing process. According to the process, onion which does not go bad and does not get rotten is selected and peeled, the head and the root are cut, the cleaning is carried out, the cleaned onion is diced and is slightly pressed for juice extrusion; the onion dices are baked and are then subjected to picking, quality checking, package and finished product warehouse entering, and the dried onion is prepared; too small onion dices are subjected to pre-boiling softening, the sterilization is synchronously carried out, pulp in the baking step and pulp in the pre-boiling softening and sterilization step are collected, pectinase and cellulose are added for enzymolysis, the materials are subjected to homogenizing treatment, concentration is carried out after the materials which are not treated through the primary enzymolysis are removed, the concentrated pulp is subjected to secondary enzymolysis, the onion pulp subjected to the secondary enzymolysis is subjected to spraying, drying and package, and the onion powder is prepared. In the onion producing process provided by the invention, the dried onion can be produced, meanwhile, the onion leaching liquid in the technical process and the pulp in the baking step are collected for enzyme treatment, then, the onion powder is prepared, the onion utilization rate in the producing process is greatly improved, the production cost of the dried onion is reduced, and the economic benefits are improved.

Description

technical field [0001] The invention relates to the technical field of deep processing of agricultural products, in particular to a new process for producing dried onions with onions as raw materials. Background technique [0002] As a kind of vegetable and seasoning, onion is widely used in people's diet.
