What is coconut flour?

Coconut flour is a milled coconut meal derived from the meat of coconuts. It is high in insoluble dietary fiber and protein.

Production of this flour is very economical. It has high nutritional content, and is naturally gluten-free—giving it a number of uses in bakery products such as breads or cookies.

Origin

Coconut (Cocos nucifera L.) is an important oil crop native to south-east Asia. It is widely used as a source of fiber in foods and beverages. Virgin coconut oil is used widely around the world due to its health benefits. Defatted coconut flour, a solid byproduct with 5% oil content has been used as animal feed or fertilizer.1

Commercial production

Coconut flour is made by milling dried/desiccated coconut endosperm (copra). The oil is removed by pressing and/or solvent extraction and the remaining coconut meal is milled into fine flour. Virgin coconut meal, on the other hand, is obtained after removal of virgin coconut oil from fresh coconut meat.1

Composition

This flour contains:

  • 3.6% moisture
  • 3.1% ash
  • 10.9% fat
  • 12.1% protein
  • 60.9% total dietary fiber (56.8% insoluble and 3.8% soluble)
  • 70.3% carbohydrates

Function

Coconut flour is a dietary fiber which can improve the nutritional value of baked products. It can also be used to decrease glycemic index or as a high-grade protein source in baked goods. Using this flour up to 15% in bakery formulations can lower gumminess and chewiness and improve texture. Cake baked with 10% coconut flour performed better than control in sensory testing. Increased concentration of coconut flour can impact the product’s color.2

Nutrition

Coconut flour is rich in dietary fiber upon which fermentation can produce short chain fatty acids such as butyrate, acetate and propionate. Coconut flour fiber content is higher than in oat bran (8.3%) and flax seed (28%). It is also rich in proteins containing lysine, arginine, and glutamic acid. It can also provide a number of benefits related to coronary heart disease, cancer, etc.2

Applications3,4

The flour can be used in:

  1. Biscuits to improve protein and dietary fiber value economically
  2. Wheat bread formulations (10-20%) with acceptable sensory and nutritional profiles
  3. Functional foods to increase their nutritional value
  4. Breads, pies, cookies, cakes and desserts

FDA regulation

21CFR101.12 delineates the regulations for reference amounts that are consumed per eating occasion. Coconut flour quantities are to be labelled as _tbsp(s) (_g); _cup (_g).
