Problems solved by technology

The pressing method is the oldest technology. Although the process is simple, it is labor-intensive and the extraction rate is not high.
And the cost is high, the protein denaturation in the meal is large, so it can only be used as feed

Embodiment 1

[0044] Embodiment 1, the extraction of oat oil

[0045] 1. Selection of raw materials

[0046] Different parts of oats contain different nutrients. Two kinds of naked oat bran were selected, and the nutritional composition was analyzed, and the fat content in the bran of the two kinds of oats was the most. The content of linoleic acid in oat lipids is relatively high, accounting for 38.11% to 52.10% of the total fatty acids. Therefore, oat bran is selected as raw material to develop functional oat oil rich in unsaturated fatty acids.

[0047] 2. Selection of extraction reagents

[0048] According to the extraction characteristics, lipids can be divided into free and bound forms. Solvent extraction is the most commonly used method, and the different solvent systems vary widely. But almost none of the solvent systems can effectively extract cereal lipids. Non-polar solvents such as hexane and ether can effectively extract neutral lipids, but have poor extraction ability for...

Embodiment 2

[0083] The extraction of embodiment 2, oat oil and refining

[0084] 1. Extraction of oat oil crude oil

[0085] After sieving oat bran (purchased from Kangbao County Starch Factory, Hebei Province) with a 20-mesh sieve, take 90g, add 900ml of petroleum ether (Beijing Chemical Reagent Factory), and extract in a water bath at 80°C for 12 hours to obtain an extract . The obtained extract was centrifuged at 4000r for 20min, then vacuum-filtered under the condition of 0.1mPa, and the filtrate was subjected to a rotary evaporator (Shanghai Yarong Biochemical Instrument Factory, model: RE52-98), at 40°C and under the condition of 0.1mPa, Concentrate by rotary evaporation, recover petroleum ether, let stand for precipitation for 12 hours, and obtain crude oat oil.

[0086] 2. Refining of crude oat oil

[0087] 1) Degumming

[0088] Take three parts of crude oat oil prepared in step 1, heat them in a water bath to 85°C, add deionized water at the same temperature as 5%, 10% or 15% o...

Abstract

The invention discloses an oat oil and an extraction method and application thereof. The oat oil is extracted by the following steps: firstly, the oat bran is added in petroleum ether and is reflux-extracted under 60-80 DEG C for 4-12 hours to get extraction liquid; secondly, oat oil crude oil is got by removing the residue in the extraction liquid and rotary evaporating to remove the petroleum ether. The method of the invention uses the bran which has the most oil content in the oat as raw material, uses the petroleum ether to extract, and has the unexampled advantages of little residual oil content, high oil extraction rate, low processing cost, good production conditions, and fully usage rate of oil plants and so on. The oat oil gained after being purified has the colors from yellowish green to brownish yellow, has good transparency, and has full-bodied natural oat fragrance. The physical and chemical indexes of acid valence, iodine valence and saponification value etc. have all met experimental design requirements, and the oat oil has the qualification to be taken as cosmetics additive.

Description

technical field [0001] The invention relates to an oat oil and its extraction method and application. Background technique [0002] Oat (Avena Sativa L.) is a herbaceous plant of the Poaceae Avena genus, and it is also an ancient crop. There are two types of oats cultivated now: lemma type and naked type. The glumes of lemma-type oats are long and hard, and the grains are surrounded by the glumes when they mature. The glumes of naked oats are short and soft, and the grains are exposed when they are mature. The paddy type is mainly cultivated in various countries in the world, and the oats cultivated in my country are mainly naked grain type. [0003] Oats are one of the eight major cereal crops. Oats are distributed in more than 40 countries on five continents in the world, with an annual planting area of ​​2.5 million hectares. Most of them are husk oats, and their concentrated production areas are located in Asia, Europe, and North America north of 40 degrees north lati...
