Processing technology of ultra-fine powder of Moringa oleifera leaves

Abstract

The invention discloses a processing technology of ultra-fine powder of Moringa oleifera leaves. After fixation is performed on fresh Moringa oleifera leaves, dehydration is performed through vacuum freeze drying, and the entire dehydration process are anaerobic and low-temperature; no loss of effective nutritional ingredients of the Moringa oleifera leaves are caused basically, particularly, vitamins, amino acids, flavonoids, chlorophyll and other functional ingredients are reserved perfectly, and when the method is compared with a method of hot-air high-temperature drying dehydration, the product quality is improved greatly; during freeze drying, when the method is compared with a method in which a large number of materials are stacked and stirred, the materials in each layer of materialtrays are thin, and the materials in each material tray can be stirred independently, so that the dispersion effect is better; when the method is compared with a method in which the raw materials arelaid into several thin layers for drying, each layer is stirred so that the drying effect is better; and on the premise of the same drying effect, more of the raw materials can be arranged in each layer of the material trays so that industrial production is facilitated, and material loading and unloading are convenient through mobile arrangement of a vehicle component and a crate.

Description

technical field [0001] The invention belongs to the technical field of food processing, and in particular relates to a processing technology of superfine powder of Moringa oleifera leaves. Background technique [0002] Moringa leaves are the leaves of the tropical plant Moringa oleifera, which has high nutritional value and is one of the plants approved by the state for both medicine and food. Moringa leaf powder is nutritious and comprehensive. Moringa leaf is a high-calcium plant product. The calcium content is more than 4 times that of milk. In addition, it also contains high potassium, iron, zinc and other trace elements, and contains protein and amino acids similar to soybeans. A functional food containing complete nutrients, a person only needs to eat about 5 grams per day to supply the nutritional needs of the human body for a day, so it can supplement calcium, iron, potassium, and zinc, and can provide weight-loss consumers with Sufficient nutritional needs will no...

Problems solved by technology

[0003] In the prior art, Moringa leaves are mainly processed into superfine powder after dehydration and drying of fresh Moringa leaves, which are used as beverage brewing and food and beverage raw materials. However, in the current product processing technology, fresh leaves of Moringa leaves are dehydrated using high Drying and dehydration will greatly damage the color and aroma of the product, the color will turn yellowish brown, the aroma will be lost, and the taste will lose its freshness, and the active ingredients will be seriously lost during high-temperature drying. In order to solve the above problems, the present invention provides the following technical solutions
