Cottonseed is the seed of the cotton plant. Mature seeds weigh about a 1/10th of a gram and are brown and ovoid in shape. The Cotton Bolls are harvested and then are processed in a Cotton Gin. The ginning process removes the long fibres from the boll, which are then sold to spinning and weaving factories for textile manufacture. The remaining seed is sometimes further processed to remove the shorter fibers. The shorter fibres are known as cotton lint.
Cottonseed has a value as a raw material for oil extraction by crushing and extraction of the oil.
Cottonseed also has a value for direct feeding to Ruminants (such as cattle) both in the Dairy and Feedlot industries.
Sunflower seeds are the fruits of the sunflower, the seeds are 10-15 mm long and 4 mm broad, cylindrical or drop-shaped. The sunflower seed consists of a hard hull (pericarp) and a kernel, which is the actual seed. There are two major types of sunflower seeds:
- Oil type seeds contain about 40% oil and represent 80-95% of sunflower seed production. The hulls (20% of the seed) are black and tend to adhere to the kernels (USDA, 2010). Oil types are grown for their oil, which after processing produces both oil and an oil cake (sunflower meal), which is a popular protein-rich ingredient of livestock feeds. Discarded seeds from the oil extraction process may be fed whole to livestock.
- Non-oil types, or confectionery types, contain 30% oil and represent 5-20% of sunflower seed production. The hulls (40% of the seed) are of variable colour (black, white, or striped grey/black and white) and are easily removable. Most of the non-oil seeds are destined for the confectionery market. The smallest seeds are used as birdseed and pet food.
Glycine max, commonly known as Soybean in North America or Soya Bean in British English, is a species of legume native to East Asia, widely grown for its edible bean, which has numerous uses as a human and animal foodstuff. The plant, classed as an oilseed by the UN Food and Agriculture Organization, produces significantly more protein per acre than most other uses of land.
Hochfeld Grains trades in Soya beans for use in Oil crushing factories or in Full Fat Soya Factories.
