. Maize Oil

Maize oil is extracted from corn germ; it may be processed into edible oil, margarine, mayonnaise, soup stock, printing ink and soaps, etc.  Meanwhile, the cholesterol content in maize oil is much lower than other plant oil. 

Description Standard
Moisture and Volatile <0.50%
Impurity <0.20%
Acid Value (mg KOH/gram oil) <8.0
Colour Value Y<50.0 R<6.0

2. Corn Steep Liquor 

Corn Steep Liquor is a kind of byproduct produced in the processing course of corn starch.  The corn, as the raw material, enters into a soak tank for soak after pre-purified.  Then the corn is soaked in 0.15% sulfurous acid solution for over 48 hours at a soak temperature 52 degree.  The free protein and free fat contained in the corn as well as part of sugar phospholipids are extracted in the extraction course.  Such corn steep liquor is made into finished corn steep liquor after evaporation concentration. 

Description Top Grade 1st Grade
Moisture% 50-60 50-60
Protein (D.S)% >45.0 >42.0
Total Phosphorus (D.S)%        >1.20 >1.201.00
Sulphur Dioxide% <0.30 <0.30

 3. Corn Starch

Corn Starch is a principal product of processing corn, one of nature's major renewable resources.  It is also a key material for the manufacture of corn-based biochemical products ranging from corn sweeteners to amino acids.  Also corn starch itself is one of the important raw materials for food, paper, and textile industries.

Description Standard
Appearance White powder
Odour No Smell
Moisture <14.00%
Protein <0.50% (D.B.)
Fat                                          <0.20% (D.B.)
Ash <0.15% (D.B.)
SO2 <30.0 mg/kg
Finenss (100 mesh) >99.5%
PH Value 4.5 - 6.0
Whiteness (relative MgO) >92.0%

4. Waxy Corn Starch

Waxy corn starch is made of the waxy corn and has a better paste stability than native corn starch.  It has better characteristics in clarity and texture.  Waxy corn starch could be used as stabilisers and thickeners for food products, particularly those undergoing large temperature changes during processing and preparation. 

Description Standard
Appearance White Powder
Odour No Smell
Moisture <14.0%
Protein <0.5% (D.B.)
Fat <0.15% (D.B.)
Ash <0.15% (D.B.)
SO2 <30ppm
Fineness (100mesh) >99.5%
PH Value 4.5 - 6.0
Whiteness (relative to MgO) >90.0%
Viscosity                                      600 BU (the peak of Barbender viscosity)



5. Corn Gluten Meal

Corn gluten meal is a byproduct of corn processing, typically characterised by its high protein and high energy ingredient resulting from the corn wet milling process.  Corn gluten meal can be applied as feed additives for the production of a wide variety of feeds such as fish feed and other animal foods. 

Description Standard
Protein >60.00 (W.B.)
Moisture <12.00%

 
6. Corn Fibre Feed

Corn fibre feed consists of over 20% protein and is a byproduct of corn processing containing protein, fibre, phosphorus, and potassium.  Corn fibre feed is also largely used as feed for animals.  

Description Standard
Protein >18.00% (W.B.)
Moisture <12.5%


 7. Corn Germ Meal

Taken from the extraction of corn oil, the residue of the germ of corn kernels undergoes the drying process and form corn germ meal, which is a major constituent of animal feed.
 

Description Standard
Protein >18.00% (D.B.)
Moisture <12.00%
Fat <10.00%
