A process for preparing a processed blend from two or more fresh plant materials, including: 1) a first fresh plant material containing at least 5 mg/kg of lipophilic vitamin selected from provitamin A, vitamin E, vitamin K and combinations thereof; and 2) a second fresh plant material containing hydrophilic vitamin selected from at least 1 mg/kg of vitamin B5, at least 1 mg/kg of vitamin B6, at least 200 μg/kg of vitamin B11, at least 100 mg/kg of vitamin C and combinations thereof; said process comprising: A. a first pre-treatment regime for increasing the bioavailability of the lipophilic vitamin contained in the first plant material, comprising: • providing pieces of the first fresh plant material; • cooking said pieces by heating them to reach an internal temperature of at least 80 °C for at least 2 minutes; • comminuting the cooked pieces to produce a lipophilic vitamin containing puree; and said first pre-treatment regime comprising the addition of 1-50% of oil by weight of the first plant material, said oil being a lipid selected from the group consisting of triglycerides, diglycerides, monoglycerides, phospholipids and combinations thereof; and B. a second pre-treatment regime for stabilising the hydrophilic vitamins contained in the second plant material comprising: • providing pieces of the second fresh plant material; and • blanching said pieces by heating them for 1-300 seconds to reach an internal temperature of at least 60°C to produce a hydrophilic vitamin containing mass; C. combining the lipophilic vitamin containing puree and the hydrophilic vitamin containing mass; wherein the lipophilic vitamin containing puree is homogenised at a high pressure of at least 50 bar before or after being combined with the hydrophilic vitamin containing mass. 1) a first fresh plant material containing at least 5 mg/kg of lipophilic vitamin selected from provitamin A, vitamin E, vitamin K and combinations thereof; and 2) a second fresh plant material containing hydrophilic vitamin selected from at least 1 mg/kg of vitamin B5, at least 1 mg/kg of vitamin B6, at least 200 μg/kg of vitamin B11, at least 100 mg/kg of vitamin C and combinations thereof; A. a first pre-treatment regime for increasing the bioavailability of the lipophilic vitamin contained in the first plant material, comprising: • providing pieces of the first fresh plant material; • cooking said pieces by heating them to reach an internal temperature of at least 80 °C for at least 2 minutes; • comminuting the cooked pieces to produce a lipophilic vitamin containing puree; and said first pre-treatment regime comprising the addition of 1-50% of oil by weight of the first plant material, said oil being a lipid selected from the group consisting of triglycerides, diglycerides, monoglycerides, phospholipids and combinations thereof; and • providing pieces of the first fresh plant material; • cooking said pieces by heating them to reach an internal temperature of at least 80 °C for at least 2 minutes; • comminuting the cooked pieces to produce a lipophilic vitamin containing puree; and B. a second pre-treatment regime for stabilising the hydrophilic vitamins contained in the second plant material comprising: • providing pieces of the second fresh plant material; and • blanching said pieces by heating them for 1-300 seconds to reach an internal temperature of at least 60°C to produce a hydrophilic vitamin containing mass; • providing pieces of the second fresh plant material; and • blanching said pieces by heating them for 1-300 seconds to reach an internal temperature of at least 60°C to produce a hydrophilic vitamin containing mass; C. combining the lipophilic vitamin containing puree and the hydrophilic vitamin containing mass;
