1.2.7 Palm and Palm Kernel Oil
The oil palm fruit, which is obtained from the palm tree (Elaeis guineensis L.), is a drupe formed in tight bunches. Palm fruit is mainly used for the extraction of palm oil driven by a lower price, and the fact that one hectare of oil palm plantation can produce up to 10 more times oil than other leading oilseed crops (Mba et al. 2015). Palm oil can be divided into crude palm oil, obtained from the fruits mesocarp, and palm kernel oil. Both are key important in world trade. Indeed, palm oil was the fourth most produced commodity within the “processed crops” classification of FAOSTAT, surpassed only by beer of barley, sugar, and molasses. Palm oil production has boomed over the last decades caused by an increasing use as frying oil, as an ingredient in foods and other products such as detergents, and biodiesel production (Pirker et al. 2016). As shown in Figure 1.2, total world production of palm oil increased from 45.78 Mt in the year 2000 to 57.33 Mt in 2014. In 2019, the total world production of palm oil has been calculated as 70.90 Mt, representing a 16.16% annual increase during the last decade.
Malaysia and Indonesia have been the center of this impressive increase. As an example, planted areas increased from 3.37 and 2.01 Mha in 2000 to 5.11 and 9.28 Mha in 2017, which represent an averaged 8.90 and 27.09% annual increase during the period 2000–2017 in Malaysia and Indonesia, respectively. The USDA recently forecasted the Indonesian oil palm harvested area for 2018/2019 as 11.3 Mha. In 2016, Vijay et al. (2016) assessed the impact of oil palm on deforestation and biodiversity loss and reported that 45% of sampled oil palm plantations evaluated in Southern Asia came from areas that were forests in 1989 (less than three decades). Similar conclusions were obtained by Henders et al. (2015), who observed that over 50% of Malaysian and Indonesian oil palm plantations in 2005 were on land that was forest in the 1990s. This has led not only to obvious negative environmental issues, but also to closer scrutiny from consumers. However, as global demand for food increases and land availability in those countries becomes scarcer, governments of developing and emerging countries such as Brazil, Peru, and some African countries are increasingly promoting palm tree cultivation (Pirker et al. 2016). Nowadays, the palm tree is cultivated in several countries with adequate temperature, sunlight, and rainfall (Figure 1.1). However, major palm oil producers continue to be Indonesia, Malaysia, and Thailand with an annual productions in 2017 of approximately 29.27, 19.67, and 1.85 Mt. As shown in Figure 1.3, Malaysia and Indonesia are also the largest palm oil exporters with approximately 22.76 and 13.81 Mt exported during 2017.

Major palm oil importers in 2017 were India, China, and Pakistan with 8.26, 4.48, and 2.60 Mt respectively.

1.2.8 Rapeseed and Canola Oil
The genus Brassica, which is the most important within the Brassicaceae family, includes the six interrelated species Brassica nigra, Brassica oleracea, Brassica rapa, Brassica carinata, Brassica juncea, and Brassica napus (Cartea et al. 2016). Both rapeseed and canola belong to the Brassicaceae family. In some countries, the term rapeseed oil refers to the oils for industrial use, while canola oil is used to refer to the edible cooking oil. Canola is a subgroup within the rapeseeds and include those Brassica species having seeds containing oil with under 2% erucic acid and low levels of glucosinolates. As an estimate, Daun (2015) recently suggested that, to identify the amount of rapeseed crops that are canola quality, a good estimate can be obtained by assuming that all production in North America, Australia, Scandinavia, and Western Europe is canola quality, while only 10 and 75% of the production in China and Eastern Europe are canola. In the current chapter, all Brassica seeds utilized for oil production will be referred to as rapeseeds. Currently, rapeseeds rank second in world production of oilseeds (third if considering palm oil). According to data accessed from the USDA, world production of rapeseed during 2018/2019 was 70.37 Mt (USDA 2019a). Production of rapeseed in the EU increased from 19.02 Mt in 2009 to 19.80 Mt in 2018, with a historical maximum production of 24.26 Mt in 2014 (European Commission 2019). Rapeseed has a long history of use in Europe, Scandinavia, China, and India and has been more recently introduced into Canada and Australia (Daun 2015). Rapeseeds are adapted to the cool extremes of the temperature zones: although the optimum growth temperature is around 10 °C, minimum temperatures for growth have been reported to be near 0 °C (Daun 2015). Major rapeseed growing areas, shown in Figure 1.1, include temperate areas of Europe, Asia, and to a lesser extent, North America. Indeed, 41.5 and 39.3% of the total rapeseed oil production was carried out in Europe and Asia, respectively (Figure 1.4). Rapeseed oil was ninth most produced commodity within the “processed crops” classification of FAOSTAT, and the third most produced oil only surpassed by palm oil and soybean oil, which ranked fourth and sixth, respectively.
In the EU‐28 the area harvested increased from 6.17 Mha in 2008 to 6.96 Mha in 2018 (European Commission 2019). As shown in Figure 1.4, biggest producers in 2017 were China, Germany, and Canada (UN 2019). Canada is currently the major rapeseed oil exporter. Indeed, according to data obtained from FAOSTAT, 2.93 Mt of rapeseed oil were exported during 2017 (UN 2019). Although there will continue СКАЧАТЬ
