Abstract
The invention discloses an okra seed oil and an extraction method of the okra seed oil. The extraction method comprises the following steps of: drying okra seeds, grinding the okra seeds, adding an extracting solvent, carrying out stirring extraction, reducing pressure for suction filtration, collecting filtrate, carrying out vacuum separation, and recovering the extracting solvent, thus obtaining the okra seed oil. The invention adopts a solvent method to extract the okra seed oil, so that the extraction method has the characteristics of high extraction rate, good product quality, small investment of production equipment, simple technology, easiness for industrial production, and the like; and the utilization problem of seeds in the comprehensive development of okra is effectively solved.
Description
Technical field
The invention belongs to the Vegetable oil lipoprotein field, relate to a kind of grease and extracting method thereof of okra seed.
Background technology
Okra belongs to Malvaceae Abelmoschus annual herb plant, is nutritious delicious vegetables, originates in Africa, and after the successful introduction of inland of China, cultivated area enlarges rapidly in recent years, and each surrounding city of the whole nation has cultivation now, and output is increased sharply.The okra flesh texture is tender, is of high nutritive value, and unique flavor is the important outlet new type of health vegetable variety of current China.Because ripening stage of okra capsule is short, as it is untimely to gather, meat is aging rapidly, and fiber increases, and edibleness namely reduces even not edible, and peasant household has to allow its tender fruit natural maturity, gathers in the crops its seed, i.e. okra seed.
Measuring after deliberation the okra seed oleaginousness is about 20%, and it forms take unsaturated fatty acids pinolenic acid and linolic acid as main, and content accounts for more than 60%, and wherein the polyunsaturated fatty acid linoleic acid content is up to 40%.Studies show that unsaturated fatty acids has the important physiological function such as reducing blood-fat, antithrombotic, adjusting immunity system, so okra seed oil have the potentiality that are developed further into healthy edible vegetable oil.At present, the okra seed oil phase closes product and occurs not yet at home, and the extraction research of okra seed oil also has no report.
Summary of the invention
The purpose of this invention is to provide the extraction process of the okra seed oil that a kind of production cost is low, oil yield is high, dissolvent residual is little and obtain colory okra seed oil.
For achieving the above object, technical solution of the present invention is: a kind of extracting method of okra seed oil is characterized in that it is comprised of following steps:
A. drying and crushing adopts hot air dryer that okra seed is carried out drying, and temperature of charge is controlled at 50～60 ℃, and dried okra seed water content is controlled at about 5%, then adopts pulverizer to pulverizing, and the control globule size is the 30-60 order;
B. lixiviate changes the okra seed dregs of rice after pulverizing in the container over to, adds the organic solvent sherwood oil, control solid-liquid ratio 1:(5～10), extracting temperature is 55～65 ℃, stirs and extracts 3.5～4.5h;
C. filter, the lixiviate mixture in the step (2) is carried out filtration under diminished pressure by filter, remove okra seed dregs of rice powder and other solid suspended substance, get extracting solution;
D. separate, extracting solution is carried out vacuum-evaporation separate under 30～45 ℃ of conditions, reclaim and extract solvent, namely make okra seed oil.
Such as the okra seed oil that present method makes, its product index is as follows.
The okra seed oil phase that uses this method to make is 0.8～0.9 to density, and refractive index is 1.4～1.5, and acid number is 1.5mg/g～3mg/g, and peroxide value is 0.5mmol/kg～1.5mmol/kg, and iodine number is 100gI
2/ 100g～110gI
2/ 100g, saponification value is 140mg/g～160mg/g, and unsaponifiables is 2%～5%, and lipid acid consists of palm fibre and puts acid 35%～38%, oleic acid 16%～18%, linolic acid 40%～43%, stearic acid 2%～4%.
Advantage of the present invention has been effectively to solve okra and has produced the utilize problem of later stage to seed, and extract by solvents okra seed oil extraction yield is high, good product quality, and small investment of production equipment, technique is simple, is easy to suitability for industrialized production.
Embodiment
Below in conjunction with embodiment the present invention and embodiment thereof are described in further detail, but do not mean that and limit the scope of the invention.
