Problems solved by technology

In addition, because cold pressing omits the pretreatment process of high-temperature steaming and frying, the oil bodies in the raw material are still distributed in the undeformed protein cells of the raw material in a dispersed state, so the oil yield of cold pressing is lower than that of hot pressing

Embodiment 1

[0038] A kind of method of cold pressing coupling low-temperature pulverization of the present embodiment prepares instant high-fiber coconut powder, described method comprises the following steps:

[0039] (1) Cleaning and slicing: the purpose of cleaning is to remove various impurities in the raw coconut meat, such as: iron, stones, soil blocks, etc., and the impurity content of the raw materials must not exceed 0.2%; Cut the sliced ​​meat into 3-4mm coconut flakes;

[0040] (2) Drying: drying the coconut flakes obtained in step (1), adopting a low-temperature drying process to reduce the moisture to below 4%, and the raw material temperature must not be higher than 60°C in the drying process; the low-temperature drying process is to reduce the amount of protein transsexual;

[0041] (3) Broken, tempered: add water to step (2) drying gained coconut flakes, control the moisture content of coconut oil raw material to be 10%, under room temperature, coconut meat is broken, the...

Abstract

The invention discloses a method for preparing instant high-fiber coconut powder by cold press coupling and low temperature pulverization, which relates to the technical field of food processing and storage. The method adopts a coupling process of low temperature drying, cold pressing degreasing, liquid nitrogen ultra-low temperature freezing and pulverizing, which comprises the steps of pulverizing the vacuum freeze-dried desiccated coconut into powder having a particle diameter of 40 mesh or less; pressing the material for 2 to 4 times by a German KOMET cold press machine, wherein the single-head processing capacity is 6-8 kg/h, and the oil content of a cold pressed cake can be reduced to 6.5%, and performing ultrafine pulverization on the cold-pressed desiccated coconut cake by using aliquid nitrogen pulverizing apparatus. The method of the invention can not only obtain high-quality coconut oil, but also is non-toxic, harmless, environmentally friendly, non-polluting, non-thermal processing, and the whole processing process is carried out at a low temperature state, the components in an oil material are not oxidized, the protein in the mash is invariant, and the biological activity of the active ingredients in the cake is retained to the utmost extent, the safety is high, and the extraction efficiency, the yield and the product quality are remarkably improved.

Description

technical field [0001] The invention relates to the technical field of food processing and storage, in particular to a method for preparing instant high-fiber coconut powder by cold pressing coupled with low-temperature pulverization. Background technique [0002] Coconut (Cocos nucifera L.) is the fruit of the palm plant coconut tree, which is currently cultivated in more than 90 tropical countries around the world. Coconut is a symbol of Hainan and has important economic value. The nutritional value of coconut is very high. Modern medical research shows that coconut juice and coconut meat contain protein, sugar, oil, vitamins, calcium, phosphorus, iron and other trace elements and minerals, which are good products for both medicine and food. Coconut is an oil plant with high oil content, which can reach more than 60% in dried coconut powder. If it is directly crushed at low temperature, the coconut powder will be viscous at room temperature due to the high oil content, wh...
