Embodiment 1

[0046] Embodiment 1: the preparation technology of Rou Yaxiang peanut oil

[0047] Prepare Rou Ya Xiang Peanut Oil as follows

[0048] (1) Get 25kg of peanut kernels, and use the TQLZ60*100 screening machine to select;

[0049] (2) Add the screened peanuts to a short-medium wave infrared heating machine for processing by vacuum suction (temperature 120-140°C, processing distance 20cm, material thickness 5cm, wavelength 2.5μm), and the processed peanuts are heated at room temperature Cool for 5 hours, and use LXT-1 to remove the red coat;

[0050] (3) Utilize coarse crushing machine to pulverize to about 40 orders;

[0051] (4) Squeeze for 40min under a pressure of 60Mpa (three-column hydraulic oil press);

[0052] (5) Utilize BAJ1 / 310-U plate-and-frame filter to filter (filter pressure 2bar) to obtain peanut oil.

[0053] At the same time, the influence of different infrared heating temperatures and times on peanut oil was investigated, such as Figure 1-4 shown.

Abstract

The invention discloses a press prepared peanut oil pretreatment method, belonging to the technical field of food processing. The invention adopts the pretreatment method of short and middle infrared heating, overcomes the adverse effects of high temperature stir-frying seeds in pretreatment, the obtained peanut oil, has the unique rich aroma and taste of smooth aromatic peanut oil, is light in color, has no burnt smell, the obtained peanut meal has less denaturalization after the peanuts are pressed into oil, can be recycled, is simple in preparation process, the cost of investment and operation at an early stage is relatively low.

Description

technical field [0001] The invention relates to a pretreatment method for preparing peanut oil by pressing, and belongs to the technical field of food processing. Background technique [0002] The traditional peanut oil extraction process mainly refers to two kinds of pressing method and leaching method. The pressing method is a method of extracting the oil in the pressed material by the extrusion of mechanical external force. The leaching method is a method of extracting the oil from the material embryo or pre-pressed oil cake by using the characteristics of certain organic solvents to "dissolve" the oil. As people pay more attention to food safety, pressing method has increasingly become the focus of people's research. [0003] Traditional aroma peanut oil preparation process such as Figure 5 shown. [0004] The cotyledons and germs of peanuts contain high protein, reducing sugar, pentose, sucrose, etc. The main function of high-temperature steaming and frying is to ma...
