Processing method for producing almond oil

Abstract

The invention discloses a processing method for producing almond oil. The method includes the steps of drying in the sun, grinding, carrying out heat preservation, making into cakes, cooking, pressing and filtering; specifically, the steps are as follows: taking shelled almonds, drying in the sun to control the moisture content to be 3-5% to obtain the dried almonds, grinding using a grinder and sealing in a container, carrying out heat preservation at 50-60 DEG C for 2 hours, making into cakes, placing the cakes in a bamboo steamer for cooking through water vapor, then pressing to obtain crude oil, precipitating for 36-48 hours, and filtering to obtain the refined oil. The almond oil provided by the invention is strong in flavor, soft, and relatively high in monounsaturated fatty acid content; therefore, the almond oil is beneficial to human health after long-term consumption, and has a high nutrient value and a health care function.

Description

technical field [0001] The invention relates to a processing method for edible oil, in particular to a processing method for producing almond oil from almonds. Background technique [0002] Almond oil, light yellow and transparent, with a delicate taste, is not only an excellent edible oil, but also a high-grade lubricating oil, which can withstand low temperatures below -20°C, and can be used as an important raw material for high-grade paints, cosmetics and high-quality soaps. Flavor and vitamins can also be extracted. At the same time, almond oil is rich in protein, unsaturated fatty acids, vitamins, inorganic salts, dietary fiber and trace elements needed by the human body. It has the functions of nourishing the lungs, invigorating the stomach, and replenishing physical strength. Its amygdalin has natural anti-cancer activity substance. [0003] At present, the production methods of almond oil include water substitution method and pressing method. The traditional water...

Problems solved by technology

The traditional water substitution process includes steps such as clearing seeds, moistening seeds, frying seeds, raising smoke, blending pulp and stirring oil, shaking and separating oil, etc. The prepared almond oil has a strong and soft flavor, but it is labor intensive and produces a large Wastewater and continuous production cannot be realized, and development is restricted

The machine pressing process developed later includes steps such as cleaning seeds, frying seeds, raising smoke, tempering, pressing, filtering, and sedimentation. Although it makes up for the shortcomings of the water substitution method, it has the advantages of a high degree of self-control and continuous production. However, the flavor of the prepared almond oil is not as good as the water substitution method, and the almond oil obtained by the method is soft and pure

Most of the traditional almond oil production process is to produce almond oil after roasting, roasting and pressing at high temperature. The nutritional components and active substances of the produced oil will be lost, and the oil production rate and oil quality will be affected. Its natural The fresh scent will also be affected
