1 Seed and pre-treatment
• With 12% of the global vegetable oil production, rapeseed represents
the third greatest volume after palm (18%) and soy (26% )
• Total production: approx. 60 million t/a
• EU production: 30% of global production; Germany 30% of EU
Rapeseed production 2012
according to „Indexmundi“

GEA Mechanical Equipment
• Press cake for feed:
• After oil extraction approx. 60% of the seed remains as press cake or flakes
containing proteins
• The press cake can be used as feed for pigs, cattle, and poultry.
• German rape seed consumption:
• The proportion of this rape cake compared to the total animal feed
increased from 1.2 to 3 million (1985 to 2008) and is greater than in other
countries
• Current demand: feed, industry
• Medium term: food
Increasing demand for proteins without
disturbing minor components

GEA Mechanical Equipment
• No pre-treatment is needed
for cold and medium warm press (press cake) - PC
• Heating for hot pressing ( rape expeller cake) - REC
• Dehulling in order to
reduce fiber content (kernel cake) - KeC
• Hexane oil extraction - Flakes
Known facts:
• Heating reduces sinapine (Jeroch et. Al 2008)
• No difference in oil content (8 to 20%) between REC and PC (Till 2007)
• Sinapine and sinapic acid content is increased by dehulling (from
14% to 50%)
• Phytic acid is increased by dehulling from 12.7% to 38% (Matthäus 1998)
• Pre-pretreatment: increased NHP in oil

• Deoiled material (solvent extraction, risk: protein denaturation and washing)
• UDP (un-degradable protein)

• Isolate > 90% protein
• NSI* and water binding potential: rape protein vs. soy protein (Kodagoda1973,
Aluko 2001, Kroll 2009)
• NSI:0.1%-0.9% (low phytic acid); water:1.32%-1.57%; oil:0.61%-1.29%

• To date the use of the intermediate rape protein products is limited
due to the minor components (e.g. phenols) in the standard cake
• Glycosinolates
• Tannines (phenolic components)
• Phytic acid
• Fibers

• Rapes seed press cake is separated into
• Globuline phase (50-60% protein + carbohydrates, oil and
lecithine)
• Albumine phase with Sinapine (approx. 33% Protein on DM)
• Wet hulls
• Minor components are separeted from Glubulines, like:
• Glycosinolates
• Tannines (phenolic components)
• Phytic acid
• Fibers
