Embodiment 1

[0032] Embodiment 1: Preparation of antioxidant composition: Accurately weigh the weight of each component in the antioxidant composition shown in Table 1 (weight of each component of antioxidant composition). At 25~30℃ and N 2 Under protection, 5g rosemary extract + 4g tocopherol + 0.5g phospholipid + 0.5g citric acid were added together to 15g sunflower oil and stirred for 30min to form a uniform oil phase.

[0033] Take 100g of DHA oil, add 0.2g of the above antioxidant composition, stir at room temperature for 15min to disperse the antioxidant evenly, if necessary, add 2 Heat slightly under protection at a temperature of 30-35°C and stir for 15 minutes. Then the DHA oil that has added anti-oxidant composition is packed in the reagent bottle, is sealed and placed in temperature 60 ℃, carries out accelerated oxidation experiment in the constant temperature and humidity box of humidity 70%, measures its content every other week (detection method is according to GB / T 5009.1...

Embodiment 2

[0040] Embodiment 2: Preparation of antioxidant composition: Accurately weigh the weight of each component in the antioxidant composition shown in Table 3 (weight of each component of antioxidant composition). At 25~30℃ and N 2 Under protection, 4.5g rosemary extract + 4.5g tocopherol + 0.5g phospholipid + 0.5g citric acid were added together to 15g soybean oil and stirred for 30min to form a uniform oil phase.

[0041] Take 100g of ARA oil, add 0.3g of the above antioxidant composition, stir at room temperature for 15min to disperse the antioxidant evenly, and if necessary, add 2 Heat slightly under protection at a temperature of 30-35°C and stir for 15 minutes. Then the ARA oil to which the antioxidant composition has been added is packed in a reagent bottle, sealed and placed in a constant temperature and humidity chamber with a temperature of 60°C and a humidity of 70% for accelerated oxidation experiments, and its content is measured every other week. Another ARA oil wi...

Abstract

The invention discloses an antioxidant composition suitable for unsaturated fatty acid and ester thereof, relating to an antioxidant. The composition comprises the following components: 10-40% of fat soluble rosemary extract, 10-40% of tocopheryl, 0.05-5% of phospholipid, 0.05-5% of citric acid, and balance of carrier oil. The preparation method comprises the following steps: weighing the components according to the weight percentage; and stirring the effective components (i.e. the fat soluble rosemary extract, the tocopheryl, the phospholipid and the citric acid) at the temperature of 25-30 DEG C and at the protection of inert gas until the effective components are dissolved or dispersed in the carrier oil to form a uniform oil phase, and thus obtaining the product. The main antioxidant in the effective components contains the fat soluble rosemary extract and the tocopheryl which belong to the hydrogen-supply-type antioxidant and have antioxidation effect; the phospholipid contained in the synergist in the effective components has the function of regenerating the hydrogen-supply-type antioxidant because of nitrogen-containing compound contained in the phospholipid, thereby achieving good synergism; and the effective components are dissolved or dispersed in the carrier oil to form a uniform and stable oil phase body.

Description

technical field [0001] The invention relates to an antioxidant, in particular to an antioxidant composition suitable for unsaturated fatty acids and esters thereof. Background technique [0002] Due to the existence of unsaturated bonds in the carbon chain, unsaturated fatty acids and their esters are prone to oxidation reactions, especially in an oxygen-containing atmosphere, catalyzed by light, enzymes or metal ions, and are prone to oxidation of unsaturated bonds, resulting in quality deterioration and loss The original nutritional value and flavor, even produce harmful substances. Even in a container filled with inert gas and protected from oxygen and light, the automatic oxidation reaction of oil is still going on. Therefore, antioxidants must be added to delay the auto-oxidation process and prolong the storage period. [0003] At present, the commonly used antioxidants mainly include butyl hydroxyanisole (BHA), butylated hydroxytoluene (BHT), propyl gallate (PG), ter...
