Abstract
One aspect of the invention relates to a packaged, oxidation-stable oil-in-water emulsion comprising: 0.1-10 wt .% of oil, said oil containing 0.3-80 g of polyunsaturated fatty acids per liter of emulsion; at least 1 mg/1 of pro-oxidative metal cations; 10-2000 mg/1 of vitamin C; and up to 98 wt.% of water; wherein the container comprising the emulsion holds no headspace and wherein the molar ratio of vitamin C to pro- oxidative metal cations exceeds 1:2. Oxidation of the polyunsaturated fatty acids contained in the emulsion, is effectively prevented, despite the fact that the emulsion contain appreciable amounts of pro-oxidative metal cations and even if the emulsion is produced under conditions in which it is in direct contact with air. Another aspect of the invention relates to a method of preparing a packaged emulsion as defined above.
Description
Technical field of the present invention
The oxidation-stabilized oil-in-water emulsion that the present invention relates to pack, it comprises the oil of 0.1-10wt%, and described oil comprises the polyunsaturated fatty acid of 0.3-80g/rise emulsion.Another aspect of the present invention relates to the manufacture method of the oil-in-water emulsion of above-mentioned packing.
Background of invention
Be to use the oils that comprises the high-load polyunsaturated fatty acid and can cause serious sick problem what the field of Food Chemistry was known.These sick problems are relevant with the oxidation of polyunsaturated fatty acid, cause the formation of volatile, dense flavor molecules (as undersaturated aldehyde).The taste attribute relevant with the oxidation product of polyunsaturated fatty acid comprises " fish ", " cardboard ", " paint ", " oil ", " rancid " and " metal ".
Also known, iron cation even can play strong pro-oxidant at the low concentration of for example 0.1mg/kg.Therefore, comprise and to produce strong sick very fast with the remarkable product of the polyunsaturated fatty acid of the obvious amount of the iron cation combination of concentration.
Know that further the oxidation of polyunsaturated fatty acid can suppress through adding antioxidant.The example of suitable antioxidant comprises the extract of tocopherol, rosemary,, anti-bad blood acyl palmitate, citric acid, ascorbic acid, TBHQ, BHA and BHT.
The oxidation of polyunsaturated fatty acid can also be by guaranteeing that not having oxygen to be present in the product that wherein contains polyunsaturated fatty acid prevents.This can by under oxygen-free atmosphere (for example nitrogen) produce the said goods and/or by having the anaerobic headroom or not having (for example, Tetra Pak in the packing of headroom
) pack this product and realize.
Production requirement precision equipment under oxygen-free atmosphere.And, use oxygen-free atmosphere to be not enough to solve the problem of the oxidation of this polyunsaturated fatty acid.The commercially available oils that is rich in polyunsaturated fatty acid often comprises the polyunsaturated fatty acid of the oxidation that exists with the peroxide form of certain content.These peroxide are nonvolatile and itself does not influence the taste of product.Yet at processing and memory period, these peroxide will be degraded into dense flavor molecules, even when anaerobic.Especially, when pro-oxidant existed, as iron and copper cation, these peroxide became the degraded of aldehyde and other flavor molecules and will carry out with very high speed.The storing temperature that raises also quickens the degraded of these peroxide.
Invention was both stated
The inventor has developed the oxidation-stabilized oil-in-water emulsion of packing, and it comprises the oil of the polyunsaturated fatty acid with high-load, makes up the oxidative cations that helps of basic (substantial) amount.Help oxidative cations,, advantageously be added in this product to provide a certain amount of these essential mineral matters, the essential part of amount every day (RDA) that this a certain amount of expression is recommended as iron and zinc cation.The emulsion of this packing has advantage: although have the polyunsaturated fatty acid of high-load and the oxidative cations of obviously measuring that helps, the oxidative degradation that it can not demonstrate owing to polyunsaturated fatty acid produces sick shortcoming.In fact, the emulsion of this packing can be stored the as many as some months and produce without any significant losing flavour in the condition of sweltering heat.
The inventor has been found that, if if this emulsion is packaged in the container that does not retain headroom and adds the very vitamin C of high concentration in this emulsion, the oxidation of the polyunsaturated fatty acid in comprising the emulsion that helps oxidative cations in addition can obtain prevention effectively, though this emulsion it with condition that air directly contacts under produce.
Detailed description of the invention
Therefore, one aspect of the present invention relates to the oxidation-stabilized oil-in-water emulsion of packing, and it comprises:
The oil of-0.1-10 weight %, described oil comprise the polyunsaturated fatty acid of 0.3-80g/rise emulsion;
-1mg/l's helps oxidative cations at least;
The vitamin C of-10-2000mg/l; With
-the water of 98 weight % at the most;
The container that wherein comprises this emulsion do not retain headroom and wherein vitamin C with help the molar ratio of oxidative cations above 1: 2.
As the term " emulsion of packing " that uses in this article refer to emulsion and adorn as described in the combination of container of emulsion.The container of adorning this emulsion can be any container that can fill in the mode that does not keep headroom in this container with this emulsion.Particularly preferred container is so-called TetraPak
The gas content that refers to the container filled as the term " headroom " that uses in this article.Term " does not retain headroom " and hints that those do not retain the container of headroom basically.Preferably, headroom is represented less than 0.1 long-pending volume % of container contents, more preferably less than 0.01 volume %.Most preferably, headroom is represented 0 volume % of the internal volume of container.
Referring to lipid material as the term " oil " that uses in this article, preferably refer at 30 ℃, more preferably is liquid lipid material in the time of 20 ℃.The example of lipid material comprises triglyceride, Diglyceride, monoglyceride and phosphatide.Most preferably, oil is triglyceride oil.According to particularly preferred embodiment, this emulsion comprises the oil of 0.5wt% at least.
