Embodiment 1

[0081] Preparation of green tea extract microemulsion. Green tea extract (available from Archer-Daniels-Midland Company, Decatur, IL) is a free-flowing powder standardized to 90% polyphenols and 50% EGCG (Epigallocatechin Gallate )). The product is very water soluble. 20%-30% GTE is dissolved in water along with 2%-10% ascorbic acid or citric acid to create the aqueous phase of the microemulsion. The oil-emulsifier phase was prepared using 30%-70% CAPMUL 471 (a C8 / C10 coconut mono / diglyceride) available from Abitec Corp. . The oil phase may contain mixed tocopherols (DECANOX MTS 90, available from Archer-Daniels-Midland Company, Decatur, IL) and soybean lecithin (BEAKIN LV1, available from Archer-Daniels-Midland Company, Decatur, IL). The different formulations (A-F) are shown in Table 1.

[0085] The Oxidative Stability Index (OSI) was determined. For sample B and sample E, the OSI at 110°C was 30.2, and these two samples had 5%...

Embodiment 2

[0095] Two commercially leading industry standards for antioxidants were compared to the antioxidant-containing microemulsions disclosed herein. The industry standards evaluated were rosemary and rosemary / green tea extract antioxidants. Figure 4 and Figure 5 A comparison of EPR and OSI data showing the functionality of industry standard antioxidants compared to the antioxidant-containing microemulsions disclosed herein is shown.

Embodiment 3

[0097] In this example, the antioxidant-containing microemulsions disclosed herein were compared to commercially available antioxidants to assess the oxidative stability of soybean oil, rapeseed oil, and NuSun oil. Oil storage evaluations were performed in an oven according to the Schaal oven test. The oils were stored in semi-closed amber Qorpak glass jars in a forced air oven at 565°C. At regular time intervals, oil samples were taken from the glass jars and the peroxide value (PV) was determined according to AOCS official method Cd 8-53. After removal, samples were blanketed with nitrogen and frozen until ready for analysis. Analyzes were performed for peroxide value, fatty acid, p-anisidine value and OSI.

[0098] The OSI values ​​obtained with rapeseed oil are in Figure 6 shown in . The peroxide value of rapeseed oil is Figure 7 shown in . Fatty acid value in Figure 8 shown in .

[0099] Depending on the concentration, green tea extract exhibits an intense red ...

Abstract

In each of its various embodiments, the present invention discloses microemulsions that carry antioxidants.

Description

[0001] The present invention relates to antioxidants. [0002] Background of the invention [0003] Lipid oxidation is a process that occurs in food systems from free radical chain reactions of unsaturated fatty acids. The presence of unsaturation in fatty acids makes fatty acids susceptible to oxidation via such free radical reactions. Such a reaction is a chain reaction comprising the steps of initiation, propagation and termination. The presence of oxidation in foodstuffs has a great influence on the shelf life of foodstuffs and can cause several off notes and even the appearance of toxic products. [0004] The effects of oxidation have been well studied. Antioxidants have been found to be effective in controlling lipid oxidation and / or slowing the rate of oxidation. Factors including temperature, pH, presence of metals, level of unsaturation, and / or other factors can lead to increased oxidation rates. Therefore, avoiding such factors can help control oxidation, but cont...
