Vegetable oils production

For some time worldwide a systematic and large expansion of vegetable oil production has been occurring, especially in southeastern Asia in 1990 the consumption of fats amounted to about 80 million tons. Eighty percent was used as food, 6% as feed, but 14%—more than 14 million metric tons—was used for industrial purposes. By the year 2000 the world fat production will have risen to over 100 million tons [3]. Also, in the future the oleo chemistry will have a broad and reliable raw materials basis. Tables 3 and 4 give information on the present and future production of important fats and fatty oils and the composition of the fatty acid mixtures that can be derived from these fats.

Compared to refined vegetable oils, the compositions of crude vegetable oils and oil and fat products are more complicated. These samples contain proteins, carbohydrates, and minerals that interfere with HPLC separation and reduce the lifetime of the HPLC column. These compounds need to be largely eliminated from the extract before HPLC analysis. Saponification and heating are used to weaken sample matrices to allow the solvent to fully access all tocopherols and tocotrienols of the sample. Liquid/liquid extraction is used to remove these polar compounds from the organic solvent layer that contains tocopherols and tocotrienols. The normal-phase HPLC method is usually used for crude vegetable oils and vegetable oil products reversed-phase HPLC can be used for animal fat products.

RRR-a-Tocopherol Concentrate occurs as a brown-red to light yellow, clear, viscous oil. It is a form of vitamin E obtained by the vacuum steam distillation of edible vegetable oil products, comprising a concentrated form of RRR-a-tocopherol. It oxidizes and darkens slowly in air and on exposure to light. It may contain an edible vegetable oil added to adjust the required amount of total tocopherols, and the content of RRR-a-tocopherol may be adjusted by suitable physical and chemical means. It is insoluble in water soluble in alcohol and miscible with acetone, with chloroform, with ether, and with vegetable oils. 

This monograph establishes specifications for two types of mixed tocopherols concentrate. Both types are obtained by the vacuum steam distillation of edible vegetable oil products, and both contain a specified minimum amount of total tocopherols (see Requirements, below), differing only in the levels of the RRR-tocopherol forms.

In addition to large increases in vegetable oil production in recent decades, a trend toward lower carcass fat contents at slaughter has also held down the rate of growth of animal fat production. This trend has been a result of two factors consumer preferences for lean meat and economic pressure to produce animals more... 

Table 8 gives world oilseed production data and includes copra. Table 9 gives world vegetable oils production and includes coconut oil. Copra meal production data are included in Table 10.

In 2001, 2.04 MT (million tons) of corn oil was produced worldwide (representing about 2% of the total worldwide vegetable oil production), with the top three producers being the United States (57%), the EU-15 (10%), and Japan (5%) (1). Compared with the 2001 world production of other vegetable oils, com oil ranks tenth, behind soybean (26.66 MT) > palm > canola/rapeseed > sunflower > peanut > cottonseed > coconut > palmkemel > and olive (1). 

Most vegetable oil production facilities are major sources of particulate matters (PM). Depending on the oilseed processed, PM emissions can be 0.1-0.3 lbs of total suspended particulate (TSP), which is about 50% PMio (PM smaller than 10 microns) and less than 2% PM2.5 (PM smaller than 2.5 microns), per ton of seed processed. PM controls would also have to be part of a facility s federal and state permits. Cottonseed oil production facilities probably also have to include NO, SO, and CO emissions in their federal and state permits. 

Fully hydrogenated vegetable oil products may also be used as alternatives to hard waxes in cosmetics and topical pharmaceutical formulations. 

Crystal polymorphic analyses were determined by means of X-ray diffraction on an Enraf-Nonius FR 590 diffractometer equipped with a Guinier camera. Visual crystal observations were made using a Leica DMLP polarizing microscope equipped with a CCTV camera. Suppliers were Golden JoMalina, Lam Soon Sdn. Bhd., and Felda Vegetable Oils Products Sdn. Bhd., all of Malaysia.
