Abstract
Relating to the technical field of corn oil preparation, the invention specifically relates to a preparation method of natural corn oil with a thick aroma, in particularly to a preparation method of natural corn oil with a thick aroma but without any essence and flavor. The method comprises the steps of preparation of refined corn oil, preparation of a corn germ cake, blending and separation. The corn germ cake is prepared by the steps of: pressing corn germs to obtain crude corn oil, then steaming and stir-frying a pressed hoecake at a high temperature in a steaming and stir-frying cauldron, thus obtaining the corn germ cake; then mixing the prepared corn germ cake with the refined corn oil and stirring the mixture, and leaving it to stand for layering; then carrying out separation so as to obtain the corn oil with a thick aroma. Without adding any essence and flavor, the natural corn oil with a thick aroma obtained with the method of the invention has a unique flavor.

Description
Technical field
The present invention relates to corn oil preparation method's technical field, be specially a kind of preparation method of natural giving off a strong fragrance corn oil, relate in particular to a kind of natural giving off a strong fragrance corn oil preparation method who does not add essence and flavoring agent.
Background technology
China is the important place of production of corn, and in recent years, along with the raising of people's living standard and going deep into gradually of health care consciousness, corn oil has been come into common people house gradually as a kind of daily oil that has nutritive value.Saturated aliphatic acid accounts for 15% in the corn oil, and unrighted acid accounts for 85%, and unrighted acid mainly is oleic acid and linoleic acid.Contain in the corn oil that human body can not synthesize and the unrighted acid that must from meals, absorb, have reduce blood cholesterol levels and triglycerides, reduction blood viscosity, improve blood microcirculation, to improve brain cell active and strengthen the effect of memory thinking ability.
Contain abundant unrighted acid in the conventional corn oil, it is hypertension, atherosclerotic and the elderly's edible health-care oil, its shortcoming is a light taste, light delicate fragrance is arranged, not as the sort of strong fragrance of peanut oil, but at present, the method that makes grease present special aroma is to add essence and flavoring agent in single grease mostly, by the taste of essence and flavoring agent to reach the purpose of perfuming.Along with the concern of people to health, domestic and international in recent years in addition great food security incident, the pollution-free food that pure natural does not have interpolation will become the food that more meets consumption propensity.
Summary of the invention
The object of the invention is, a kind of preparation method who does not add the natural giving off a strong fragrance corn oil of essence and flavoring agent is provided, and a kind of giving off a strong fragrance corn oil with natural giving off a strong fragrance taste is provided.
The preparation method of the natural giving off a strong fragrance corn oil of the present invention, comprise and produce the refined maize oil step, maize germ cake preparation process, blend step, separating step, it is characterized in that, described maize germ cake preparation process is for squeezing out raw corn oil with maize germ earlier, to squeeze corn-dodger then and be placed on high temperature steaming stir-fry in the cooking pot, make maize germ cake; The maize germ cake that makes then mixes, stirs the back standing demix with refined maize oil; Separate then and obtain giving off a strong fragrance corn oil.
Described maize germ cake preparation process is, earlier maize germ squeezed out raw corn oil, will squeeze corn-dodger then and be placed on to steam in the cooking pot and fry, and temperature evenly stirred 5-100 minute at 30-200 ℃, placed, cooled off naturally, made maize germ cake.
In the described blend step, the weight ratio of refined maize oil and maize germ cake is 100:1-99, more preferably 100:10-60.
The preparation method of the natural giving off a strong fragrance corn oil of the present invention, its detailed step is as follows:
(1) produces the refined maize oil step
Selected high-grade maize plumule squeezes out crude oil, by come unstuck, depickling, decolouring, dewaxing, deodorizing technology make refined maize oil.
(2) preparation process of maize germ cake
Earlier maize germ is squeezed out raw corn oil, will squeeze corn-dodger then and be placed on steaming stir-fry in the cooking pot, temperature evenly stirred 5-100 minute at 30-200 ℃, placed, cooled off naturally, made maize germ cake.
(3) blend step
(2) described maize germ cake in the step is put into premixing tank, and the refined maize oil of implantation step (1) slowly stirred standing demix 20-30 minute.
(4) separating step
The blend of step (3) is removed impurity in the mixture with the mode of filtering, make giving off a strong fragrance corn oil.
The mode that blend in the described step (4) filters is that filter blade, plate-frame filtering or belt are filtered.
Product of the present invention is a buff oily liquid, and mouthfeel is good, aromatic flavour, and manner of packing adopts inner wrapping, and its packing specification has 0.5L-5L.Natural giving off a strong fragrance corn oil mainly based on cold and dressed with sauce with oil, not only have the nutritive value of corn oil, and have strong fragrance, mouthfeel is pure, be at home, tourism, the optimal selection of cold and dressed with sauce oil.
Beneficial effect of the present invention is: giving off a strong fragrance corn oil of the present invention produces the raw material sources of corn giving off a strong fragrance in the squeezing corn-dodger that steams after frying, fully distribute the giving off a strong fragrance corn flavor in the squeezing corn-dodger, played the purpose of flavouring, adopt the physics perfuming process of pure natural fully, do not add any essence and flavoring agent, be the natural flavor of maize germ, will become the new guiding of following consumption.
By the natural giving off a strong fragrance corn oil of method for preparing, its color and luster (Lovibond cell 133.4mm)≤Huang 30, red 6.5; Smell, flavour have strong corn oil fragrance, free from extraneous odour; Moisture and volatile matter content≤0.20%, acid number (KOH) (mg/g)≤3.Every physical and chemical index all meets the corn oil national standard.
