Fortification of vitamin A in the cooking oil needs to be revisited given that the used oil is palm oil and fortificant form of vitamin A or retinol palmitate have to be imported. On the other hand, palm oil contains carotene as pro-vitamin A and potentially as an alternative of fortificant. The aim of this study was to compare the retention of carotene to retinol palmitate in palm cooking oil and the products fried in the oil using deep frying at 150°C. Materials used as fried products were potatoes, tofu and chicken. The quality of cooking oil that determined were the fatty acid composition, water content, free fatty acid, peroxide value, color, retention of carotene and retinol palmitate. While the quality of the products fried in the oil that determined were water, fat, carotene and retinol palmitate content. The results of this study showed that fortificant (carotene and retinol palmitate) no significant difference to the quality of cooking oil except color, retention of carotene and retinol palmitate. Fortificants also showed no significant difference to the quality of fried products. Retention of carotene showed significantly decreased with increasing frying repeatedly, but had a higher retention and significantly different than retinol palmitate. Retention of carotene in the frying pan first, second, third, fourth and fifth were in the range of 86-89%, 83-89%, 80-83%, 77-80% and 77-80%, while retinol palmitate were 68-100%, 58-97%, 51-89%, 50-84%, and 40-75%. Thus, carotene can be used as an alternative of fortificant in the palm cooking oil.

In this study, production of biodiesel from new and used palm and soybean oils was carried out using a transesterification method. The effect of catalyst amount used towards the percentage yield, soap content and heat of combustion of the biodiesel produced was investigated. The soap content and heat combustion of the biodiesel were determined using titration (AOCS Cc-95) and heat calorimeter bomb (ASTM D240-09), respectively. The results showed that catalyst concentration of 0.5 w/w% gave the best result in terms of yield of biodiesel produced from both palm and soybean oils. However, the quality of biodiesel (i.e. soap content and heat of combustion) produced from palm and soybean oils behaved differently towards catalyst concentration. Overall, both oils (palm and soybean), either new or used oil apparently showed no significant difference in term of yield or qualities of biodiesel produced. This indicates that the used oil has high potential as an economical and practical future source of biodiesel.

Asam lemak jenuh dapat dikaitkan dengan peningkatan kadar kolesterol darah yang berakibat pada penyakit jantung koroner. Minyak nabati seperti kelapa sawit mengandung asam lemak jenuh dan asam lemak tidak jenuh tunggal yang tinggi. Minyak tersebut banyak digunakan dalam proses pembuatan makanan seperti biskuit, makanan ringan, dan cokelat yang beredar di pasar.Penelitian ini bertujuan untuk menentukan kandungan asam lemak jenuh pada beberapa produk makanan yang mengandung turunan minyak kelapa sawit. Sebanyak 56 produk makanan terdiri dari biskuit, makanan ringan, produk cokelat, minyak goreng, margarin dan shortening diperoleh dari pasar di Indonesia. Lemak atau minyak yang terdapat pada produk diekstrak dengan heksan menggunakan sokhlet dan dianalisis menggunakan gas kromatografi. Hasil menunjukkan seluruh sampel mengandung turunan minyak kelapa sawit, berdasarkan profil komposisi asam lemak. Seluruh sampel biskuit, makanan ringan, mi instan dan produk cokelat memiliki kandungan asam lemak jenuh rendah (0,468 - 9,715g/takaran saji), karena kemungkinan tidak menggunakan campuran fraksi minyak sawit stearin. Satu dari 12 minyak goreng mengandung campuran minyak kelapa, namun menunjukkan kandungan asam lemak jenuh yang rendah (2,137 - 6,488 g/takaran saji). Enam dari 8 sampel margarin mengandung asam lemak jenuh tinggi (5,763 - 17,166 g/takaran saji), kemungkinan dalam proses pembuatan menggunakan campuran minyak kelapa dan minyak inti sawit. Seluruh sampel shortening memiliki kandungan asam lemak jenuh tinggi (13,651 - 14,963 g/takaran saji), karena menggunakan campuran minyak sawit dan minyak inti sawit. Secara umum, seluruh sampel mengandung asam lemak jenuh rendah dibawah 20 g/takaran saji berdasarkan Nutrient Reference Values(NRVs). Saturated fat acid can be related with the increase of blood cholesterol which responsible for coronary heart disease. Vegetable oil such as palm oil contains high saturated fat acid and unsaturated fat acid. The oil commonly used in food production processes such as biscuits, snacks, and chocolate which commonly found in the market. This research aimed to determine the saturated fat acid in some food products which contain palm oil. 56 food products were obtained in Indonesian market such as biscuits, snacks, chocolate products, cooking oil, margarine, and shortening. Fat or oil in the products was extracted with hexane using soxhlet and analyzed using gaschromatography. The result indicated that all samples contained palm oil based on the fatty acid profile composition. All biscuit samples, snacks, instant noodle, and chocolate products contained low saturated fatty acid (0.468-9.715 g/serving size) it might be due to thestearin of palm oil fraction mixture was notused. One of 12 cooking oil contained coconut oil but it indicated low saturated fat acid (2.137-6.488 g/serving size) since it might use the mixture of coconut oil and palm kernel oil. All shortening samples had high fatty acid (13.651-14.963 g/serving size) since it mixed palm oil with palm kernel oil. Generally, all samples contained low saturated fat acid less than 20 g/serving size based on Nutrient Reference Values (NRVs).
