Durian as a Source of Food
Generally, durian is consumed fresh as fruit or food products such as candy, ice cream and durian puffs after certain cooking procedures. Traditionally, durian flesh is added into dishes such as “sayur” which is the Indonesian soup made from freshwater fish as an ingredient (Rudrappa, 2015). Moreover, the durian-based sauce is used to cook “Ikan brakes”, a traditional dish in Sumatran islands, Indonesia.
Overripe durian pulps are processed to become durian paste in Thailand while unripe durian may be cooked as a vegetable (Rudrappa, 2015; Utilization of durian, n.d.). Beside the flesh, durian seeds are also valuable as they can be eaten after boiling or roasting and made into durian flour and chips (Agus, 2014). Furthermore, the young leaves and shoots of durian plant can be cooked as green vegetables as mentioned by Wan (2010). In addition, dishes such as “pulut durian” and “tempoyak” are served together with durian (Clark’s Nutrition, 2015).
Health Benefit of Durian
Durian is widely celebrated for its long list of health benefits, which include the ability to boost the immune system, prevent cancer and inhibit free radical activity, improve digestion, strengthen bones, improve signs of anemia, prevent premature aging, lower blood pressure, and protect against cardiovascular diseases. Some of the more minor benefits of durian are to reduce inflammation of the joints, help thyroid health, reduce headaches, and lower symptoms of depression, anxiety, and stress.
Most of the health benefits come from durian’s impressive vitamin and mineral content. Durian contains vitamins such as vitamin-C, folic acid, thiamin, riboflavin, niacin, B6 and vitamin A. Important minerals such as potassium, iron, calcium, magnesium, sodium, zinc, phosphorus are also found in durian. It also contains nutrients such as phytonutrients, water, protein and beneficial dietary fiber.
Relieves anaemia and promotes healthy pregnancy
Anaemia is a medical condition that reduces the level of hemoglobin in blood. Deficiency in hemoglobin can lead to fatigue, headache, insomnia and etc. In pregnant woman, anaemia can lead to abnormality and fatality of the foetus. Durian contains high amount of folate or folic acid which is essential in the production of haemoglobin. Besides that, low content of iron in durian aids in haemoglobin production alleviating condition of anaemia (Kevat, 2013). Furthermore, presence of folate in durian is important for pregnant woman as it promote regular tissue growth as well as protects the brain and spine in developing baby (Health benefits of durians, 2015).
Helps to maintain healthy bones
Durian contains a number of trace metals including calcium and potassium. Even calcium is present in low level in durian, but amount of potassium present in durian fulfils about 9 % of our body’s daily requirement. Potassium is required for the development of healthy bones. Even though the most abundant mineral of our bone is calcium, but potassium is crucial to regulate the distribution and deposition of the calcium in bones so that it is not dissolved or released into the blood excessively (Kevat, 2013).
Helps to alleviate depression and improves sleep
Durian contains amino acids known as tryptophan – a natural sleep-inducing compound. Tryptophan is required to increase the level of serotonin and melatonin. These two neuro-chemicals are required to manage our emotions. Serotonin is essential to relieve stress, sleeplessness, anxiousness, appetite as well as depression. In addition, these types of hormones help to manage sleeping function and could be utilized in the epilepsy cure (Kevat, 2013).
Durian has a wealth of vitamins, nutrients, and organic chemicals that function as antioxidants. In the battle against cancer, free radicals are vitally important, because during cell metabolism, there are by-products created, called free radicals. These free radicals can destroy the DNA of regular cells and convert them into cancer cells, which can then metastasize or form fatal, tumorous growths. All of the antioxidants which reduce oxidative stress on the organs of the body are bonuses to the immune system, and durian is packed with them, including vitamin-C, vitamin-B complex, and vitamin E, as well as phytonutrients that battle cancerous cells (Health benefits of Durian, 2015).
Aids in digestion
Durian contains high levels of dietary fibre, which are important for the normal function of the digestive system. Fibre causes bowel movement to increase in bulk, which makes it easier for them to move through the intestinal tract. Fibre also stimulates peristaltic motion and the secretion of digestive and gastric juices, further easing the entire process. By reducing conditions like constipation and blockage in the intestines, conditions like bloating, excess flatulence, heartburn, cramps, and indigestion as well as colorectal cancer can be minimized. Much of the fibre in durian is insoluble fibre, which also lowers the frequency of diarrhea for people with loose stool. Fibre also helps to reduce the amount of cholesterol in the blood by scraping LDL cholesterol out of the body and quickly removing it before it can do any damage to the cardiovascular system (Health benefits of Durian, 2015).
Durian has a wide variety of antioxidant properties stemming from its vitamin and organic chemical makeup that actively reduce the amount of free radicals in the body. Eating an excessive amount of durian can seriously boost your body’s ability to eliminate those free radicals, thereby reducing the chances of premature aging and delaying the appearance of symptoms such as wrinkles, age spots, macular degeneration, hair loss, tooth loosening, arthritis, cancer, and heart disease (Health benefits of Durian, 2015). In addition, the high water content of Durian is an added advantage along with its antioxidant content. Water keeps the skin hydrated, reduces dryness and alleviates the appearance of fine lines. It also nourishes skin for clear and smooth skin (Kevat, 2013).
Increase and encourage fertility
Estrogen is a hormone that helps in conceiving. Most of the women who suffer from fertility usually have a low estrogen level in their body which is increased with pills, injections and supplements. Studies have shown that durian contains a high level of this hormone and can act as an herbal medicine (Kevat, 2013). Besides that, durian can produce intensified sexual libido and stamina, and also reduce the chances of infertility in men and women, and increase sperm motility (Health benefits of Durian, 2015).
Used as traditional medicine
According to traditional use, durian may have antibacterial, anti-inflammatory, and vasoconstrictor properties. Traditionally, durian leaves and roots are in Malaysia used to treat fever. The juice of fresh leaves is used as an ingredient in a lotion for fevers, and the juice from the bark is used as an antimalarial in Sumatra. The Javanese also believe that durian has aphrodisiac properties. In addition, durian leaves are considered anthelmintic and are used for jaundice treatment. Decoctions of the leaves and fruits are used to treat swelling and skin conditions (Clark’s Nutrition, 2011).
On the other hand, durian can be used for purposes other than foods and medicines. Durian husks which are usually thrown as wastes after the durian pulps are consumed can be dried to be used as fuel or fertilizers for tree (Utilization of durian, n.d.). It can also be used as an ingredient for making handmade paper like artistic paper with certain pattern (Agus, 2014). Due to the strong smell, durian husks can be used as the natural mosquitoes repellent. Dr. S. Kathiresan from AIMST University discovered that durian peel can be used as a mean to recover the oil spill at coastal areas (Lim, 2011). In this case, the durian peel powder is chemically modified and acts as the efficient oil absorbent to remove the oil from the water, solving the problem of oil spills which have caused adverse effects to living sea organisms and human economic activities. According to Wan (2010), woven souvenirs such as beautiful photo album covers can now be made by using the fibers of the durian plant. Meanwhile, the polysaccharides present in the large and thick durian husk were found to possess moisturization benefits and able to trap lipids and thus durian husk has the potential to be used as the ingredient for cosmetic products (Bird, 2010). In this context, more researches are required to be done on the cosmetics potential of durian husk.
