Cashew Kernel Oil - Features & Nutrient Content

Created: 06/11/2022

Cashew nuts have a very rich nutrient content, the composition contains a lot of unsaturated fat which is very good for the body with more than 40% fat content, of which more than 80% is unsaturated fat. Also, cashews contain a large amount of Vitamin E (0.9mg/100g cashew nut), which has a very good effect on anti-aging and helps skin and hair stay strong.

Cold pressing cashew kernels yields about 40% of cashew kernel oil (Cashew Kernel oil) or also known as "Caribbean oil".

When determining the composition of fatty acids that includes Palmitic acid 8.2%, Palmitoleic acid 0.4%, Stearic acid 4.2%, Oleic acid 67.4 % and Linoleic acid 19.8% in cashew kernel oil, Kaufmann H. P. & Barve J. (1967) used a chromatographic method. Physical and chemical characteristics of cashew kernel oil:

- Form: Liquid

- Color: orange yellow

- Taste: characteristic smell

- Density at 20 degrees Celsius: 0.910 +(-) 0.010

- Refractive index at 20 degrees Celsius: 1.4660 - 1.4730

- Acid index: < 5

- Peroxide  index: <5

- Iodine index: 96 – 106

Canned cashews, cashew candies and jams, cashew vinegar
06/11/2022

With abundant raw materials and rich nutrient content, cashew apples are increasingly being paid more attention. Instead of just harvesting the seeds and then discarding the fruit, which causes a lot of waste in resources, many people are trying to get the most out of this potential fruit. Thus, products like canned cashews, candy, cashew jams or cashew vinegar were made.

Harvesting, preliminary processing, and processing of cashew nuts and cashew fruits
06/11/2022

As known, cashew fruits ripen and are harvested normally at the beginning of the dry season or at the end of the cold season. Because the botanical and morphological characteristics of the cashew tree are not favorable for mechanization, cashews are often harvested mainly by hand, not by machines.
