Abstract
A method for processing high-quality camellia oleifera seed oil free of benzo(a)pyrene residue comprises a step (1) of drying camellia oleifera seeds; a step (2) of unshelling the camellia oleifera seeds; a step (3) of performing CCD color sorting to remove mildewed camellia oleifera seeds; a step (4) of performing microwave baking of the camellia oleifera seeds; a step (5) of performing double helix low-temperature (below 65 DEG C) squeezing for make oil; a step (6) of performing washing, low-temperature treatment and oil residue separation; and a step (7) of using a compound decoloring agent to remove color and B(a)P simultaneously. By adopting the method to prepare the camellia oleifera seed oil, the oil yield is high, the storage stability is good, the obtained camellia oleifera seed oil has typical fragrance and flavor of conventional heating-crushing oil (the sense organ grading value is averagely 97.56), the damage to bioactive substances such as vitamin E and squalene and the like is reduced, the yield of the B(a)P in the oil extraction process is close to the plant oil limit standard of European Union, the average is only 2.4606 [mu]g/Kg, B(a)P cannot be detected from product oil (detected according to a GB/T22509-2008 method), and the eating safety is high.
Description
Technical field
The present invention relates to a kind of processing method of high-quality Vegetable oil lipoprotein, especially relate to one kind no benzo (a) pyrene [b (a)
P] the high quality oils Oleum Camelliae processing method that remains.
Background technology
Camellia seed oil also known as Camellia oil, are to obtain from Theaceae Camellia tea oil tree seed, are the big vegetable oil in the world four
One of fat, peculiar for China.In camellia seed oil, unsaturated fatty acid content is up to 90%, and wherein Oleic acid is 75% ~ 83%, sub- oil
Acid is 7.4% ~ 13%, very much like with olive oil, has the title of " east olive oil ".Vitamin e, spiny dogfish is contained in camellia seed oil
The several functions compositions such as alkene, tea polyphenols, to cardiovascular disease such as prevention and treatment hypertension, coronary heart disease, atherosclerosiss
Have functions that good.Camellia seed oil, as a kind of senior edible vegetable oil of health type, enjoys high-end consumers pro-gaze, promotes
The fast development of Oleum Camelliae secondary industry, but because of process technology and the equal Shortcomings of market quality supervision aspect, lead to safety to be asked
Topic is also following.
In September, 2010, China's famous camellia seed oil brand is exposed because b (a) p is significantly exceeded, and even more serious
Problem is, the not individual example of problem of commercially available camellia seed oil b (a) p content overproof, and this has caused the concussion of industry, and vast consumption
Person, after shock, is filled with the deep worry to domestic vegetable oil products safety.B (a) p is polycyclic aromatic hydrocarbon (pahs) chemical combination
Thing, is the pollutant of generally existing in environment and food, its stable chemical nature, and not facile hydrolysiss have carcinogenecity, can cause
The tumor at the positions such as stomach, esophagus, skin and canceration.European Food Science committee (scf) thinks, b (a) p is currently known
One of most representational carcinogen in the carcinogenic polycyclic aromatic hydrocarbon of kind more than 20, can exist as the carcinogenic polycyclic aromatic hydrocarbon in food and
The mark of effect.Therefore, many countries and tissue all have strict mark to the content of b (a) p in the vegetable oil of direct consumption
Accurate.Codex Alimentary Commission (cac) specifies, in edible oil and fat, the maximum of b (a) p is limited the quantity as 5 μ g/kg；The maximum limit of European Union
Amount standard (2006r1881-en-01.07.2009) is 2 μ g/kg；And China is in gb2762-2012 " pollutants in food limitation "
Middle regulation, the maximum of vegetable oil b (a) p is limited the quantity as 10 μ g/kg, and this can be 5 times of EU criteria.In consideration of it, consumers in general couple
The edible safety sex chromosome mosaicism of the edible vegetable oil including camellia seed oil exists greatly puzzles, to Oleum Camelliae industry or even entirely
The having a far reaching influence of vegetable oil industry.How the residual quantity of effective control camellia seed oil b (a) p is to ensure its edible safety, simultaneously
Its good nutrition health-care functions and good local flavor can be taken into account again, be the hot issue of Recent study.
At present, the major way that camellia seed oil produces has milling process and two kinds of extraction.Milling process has hot moulding and low temperature again
Cold pressing point.In order that Oleum Camelliae has due aromatic odor, and improve oil yield, in traditional camellia seed oil production technology
In, broken camellia oleosa seed must be carried out steaming before squeezing and fry, so that protein is sufficiently separated with oils and fatss, but during steaming stir-fry, once
Temperature is too high, and lipid in the camellia oleosa seed burning, cholesterol, protein, carbohydrate etc. are pyrolyzed, and forms a large amount of b (a) p.
Cold pressing camellia seed oil refer to Semen Camelliae dry or oven drying at low temperature after, without in conventional hot moulding technique steaming fry process, a warp
Physics shelling, after remove impurity, directly adopt low temperature (< 60 DEG C) physical squeezing mode to obtain camellia seed oil, its depth of color, acid value,
Peroxide value, carbonyl value etc., all significantly lower than hot pressed oil, only need to filter, need not carry out refine necessary to hot moulding crude oil,
And this method decreases the generation of b (a) p in the camellia seed oil course of processing to greatest extent, and effectively reduce vitamin e, angle
The destruction of the nutritional labelings such as zamene, polyphenols, plant sterol, but it is disadvantageous in that the camellia seed oil local flavor of cold pressing relatively
Light, it is for its hard defects.Solvent extraction liquefaction rule adopts the organic solvent such as light gasoline, normal hexane, using the similar principle mixing
Extract oils and fatss, recycling solvent.The advantage of this method is that oil yield is high, processing cost is low, tea seed cake quality high, and oil resource obtains
Make full use of.Its shortcoming is, more containing non-oil substances in Extractive crudeoil, and color and luster is deep, second-rate, molten containing a certain amount of residual
, there is potential safety hazard in agent.What is more important, organic solvent has enrichment effect to b (a) p and itself also contains a small amount of b
A () p, causes consumer for the strong worry leaching oily edible safety.And supercritical and subcritical fluid extraction method etc.
New camellia seed oil carries oil tech, also reaches far away the level adapting to industrialized production.
It can be seen that, several major ways that current camellia seed oil produces cut both ways, and are difficult to take into account the safety of camellia seed oil
Property, trophism and local flavor.
Content of the invention
The technical problem to be solved in the present invention is to overcome the deficiencies in the prior art, provides one kind no b (a) p Gao Pin of residual

Squeeze the due aromatic odor of Oleum Camelliae, its fragrance, the sensory evaluation scores value of local flavor are (97.56 ± 0.18) point (n=5), more traditional hot moulding
Camellia seed oil (being set as perfect condition, 100 points) is lower slightly, but no significant difference (p< 0.05).Extract camellia seed oil according to this law,
Filtering b (a) p measured value in gained crude oil through cold pressing is (2.4606 ± 0.0009) μ g/kg(n=5) (by gb/t22509-2008
Method detection), and through b (a) p scavenger process after, final products do not detect the side by gb/t22509-2008 for b (a) p(
Method detects), edible safety is splendid.
The popularization and application of the present invention can meet consumer to high-quality, the rapid growth of high edible safety camellia seed oil
Demand, can effectively facilitate the healthy and sustainable development of camellia oleiferaindustry, and its economic, society and ecological benefits are notable.
