Problems solved by technology

The almond cake after oil extraction still contains a large amount of high-quality protein. When the protein is denatured and cannot be eaten due to the oil extraction process, most of it has been used as feed, fertilizer or as a residue for a long time, resulting in a huge loss of nutritional resources. waste

Abstract

The invention discloses a production method of almond powder, which belongs to the technical filed of food processing. The method comprises the following steps: fast peeling almonds by a peeling machine immediately after the almonds are fast steamed by steam; carrying out baking and cold pressing on the almonds until the residual oil content is lower than 10 percent; adding water after the pulverization for preparing materials into paste; grinding the paste; adding warm water; carrying out centrifugation for removing slag; carrying out further centrifugation on supernatant fluid for degreasing; adding emulsifying agents into obtained clear liquid; and obtaining the almond powder through concentration and spray drying. The invention adopts a steam fast steaming peeling method, has low damage degree on the almonds, has the peeling rate higher than 98 percent, and effectively prevents the almond protein denaturation. The almonds are firstly soaked, and then carry out zymohydrolysis detoxication through emulsion, the detoxication time is obviously shortened, the water consumption is saved, the detoxication rate can be higher than 97 percent, and the hydrocyanic acid content in final products of the almond powder is reduced to 2.0 mg / kg. Various indexes such as sensory properties, solubility, protein content and the like of products of the invention are all superior to those of similar products in the existing market.

Description

technical field [0001] The invention relates to a production method of almond powder, which belongs to the technical field of food processing. Background technique [0002] Almonds are rich in protein, fat, vitamins, minerals and other nutrients. Almond protein contains 18 kinds of amino acids needed by the human body, and the proportion of amino acids is balanced. It is a good vegetable protein. The cake after almond oil extraction still contains a large amount of high-quality protein. When the protein is denatured and cannot be eaten due to the oil extraction process, most of it has been used as feed, fertilizer or as a residue for a long time, resulting in a huge loss of nutritional resources. waste. [0003] The invention overcomes the deficiencies of the prior art and provides a method for producing almond powder with almond cake as raw material. Contents of the invention [0004] The object of the present invention is to provide a kind of production method of almo...
