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 0.1-80 g of polyunsaturated fatty acids per liter of emulsion; 1-20 mg/l of pro-oxidative metal cations; 10-2000 mg/l 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.

Abstract: Process for the preparation of vulnerable oil wherein degummed and neutralized vulnerable oil is subjected to bleaching and thereafter subjected to filtration, characterized in that in the process one or more, preferably two or more, more preferably three or more and most preferably all four of the following steps a)-d) are included: a) bleaching involves both a wet step and a dry step; b) filtration is conducted in re-circulation until the filtrate has a turbidity of 0.2 FTU or less, preferably 0.1 FTU or less, before filtration of the vulnerable oil is commenced; c) after filtration the vulnerable oil is subjected to a second filtration to a turbidity of 0.1 FTU or less; d) the deodorization is conducted at a temperature of 190° C. or less until 5-20, preferably 8-20 m3 gas/kg oil is passed through the vulnerable oil.

Abstract: The invention concerns concentrates of ursolic acid or its salts and oleanoic acid, wherein (i) ursolic acid and oleanoic acid or its salts are present in an total amount for the two of more than 22 wt %, preferably 30 to 65 wt % (ii) sugar residues are present in an amount of less than 40 wt %, preferably less than 25 wt %, in particular in an amount of 1 to 10 wt % (iii) while ursolic acid and oleanoic acid or its salts are present in a weight ratio of more than 3.6, preferably 4.0 to 6.0 (iv) the balance being other materials, including glycerides and/or triterpenes other than ursolic acid and oleanoic acid and a method to make these concentrates.
