Problems solved by technology

However, there are still shortcomings: when the frying pan is heated, the temperature is 175-200°C. Because the temperature of the fried seeds is too high, although the fragrance is increased, the color of the finished sesame oil is not clear, and it has a burnt taste, which affects the taste and affects the sesame. The natural nutrients have been destroyed; the oil yield is not high when the whole grain is pressed; the oil residue is crushed, the extraction rate is not high during alcohol extraction, and the oil residue utilization rate is low and the oil yield is not high

Embodiment Construction

[0020] A method for ultrasonic-assisted extraction-pressing combined extraction of sesame oil, characterized in that it comprises the following steps:

[0021] (1) Cleaning: Wash the sesame seeds that have been removed by vibrating sieves with water for 3 times, centrifugal dehydration, and air-dry;

[0022] (2) Ripening: Put the cleaned sesame seeds into the drum oven and bake for 1-2 hours, the temperature is controlled at 120-130°C, and the temperature is lowered for later use;

[0023] (3) Grinding: Process the heated and matured sesame into powder through a grinder to obtain sesame powder;

[0024] (4) Pressing: Put the crushed sesame powder into a hydraulic oil press for pressing, and filter to obtain first-grade oil residue and sesame oil;

[0025] (5) Extraction: crush the obtained first-class oil residue into powdery oil residue, put it into the extraction tank, then pour 85% alcohol, immerse, stir evenly to cover the cylinder mouth, and extract 10-15 minutes, centr...

Abstract

The invention discloses a method for extracting sesame oil by combining ultrasound-assisted extraction and pressing. The method is characterized in that a mode of baking and aging in a drum type baking oven is adopted, the temperature is controlled at 120 to 130 DEG C, and uniform heating is realized; with low baking temperature, the damage to natural nutrients in sesame can be avoided; aged sesame is crushed and then is pressed; compared with an existing whole grain pressing mode, the mode disclosed by the invention has high oil yield; oil residues are subjected to ultrasonic cavitation, mechanical stirring, thermal effect and the like and is simultaneously mixed with an environment-friendly and reusable extracting agent, so that the extraction rate of the oil residues is improved. The sesame oil extracted by the method disclosed by the invention has the advantages of limpid color, high oil yield and high utilization rate of the oil residues.

Description

technical field [0001] The invention relates to the technical field of sesame oil processing, in particular to a method for extracting sesame oil in combination with ultrasonic-assisted extraction and pressing. Background technique [0002] Sesame, also known as sesame and flax, is the seed of flax, an annual erect herb, 60-150 cm high. It is found in tropical and some temperate regions of the world. Sesame is one of the main oil crops in China and has high application value. Its seeds contain up to 55% oil. Since ancient times, there have been many kinds of food and delicacies made with sesame and sesame oil in China, which have always been famous all over the world. [0003] At present, the preparation methods of sesame oil mainly include water substitution method, mechanical pressing method, leaching method, enzymatic method and so on. Among them, the water substitution method is the most common traditional method for producing sesame oil, the mechanical pressing meth...
