Chia is an ancient edible plant-based seed from the plant Salvia hispanica L. that can be consumed as a whole seed, seed flour, seed mucilage and seed oil11. Chia seed is also considered as ‘Novel Food’ by the European Union with no more than 10% of usage in various food categories9.
Good Dose of Fibre, Protein, Minerals, Omega-3 and Antioxidant
The incorporation of chia products in bread have become a healthier alternative for gluten-free products which are suitable for people with celiac disease3.
High dietary fibre content in chia seed promotes the feeling of fullness or post-meal satiety. It also decreases the feeling of subsequent hunger besides increasing the stool volume. Chia seeds contain high proportion of linoleic and alpha-linolenic (ALA) fatty acids, making them a great source of Omega-3 that is essential for brain function. Meanwhile, high concentration of Omega-3 in chia oil can help to fix dyslipidemia by increasing LDL, triglyceride and lower HDL cholesterol10,12.
Chia flour contains approximately two times higher protein content compared to wheat flour7 along with a dense source of essential minerals such as calcium, phosphorus, potassium, zinc, magnesium and copper6. Natural antioxidants’ source in chia seeds help in fighting the production of free radicals, which can damage cell molecules and contribute to aging1.
Better Bread Quality with Chia Products
Chia seeds form a mucilaginous transparent gel composed of soluble fibre in the presence of water8. Hence, chia seed can be used as hydrocolloids in gluten-free breads to provide better structure and increase the volume for baked products3. Chia mucilage can also be used to substitute fats in breads and cakes2
The high fat content of whole chia flour may promote a volume increase in the dough, acting as a gas retainer that softens the texture as the fat layers and gluten network are intermingled5. The incorporation of chia flour can also delay the retrogradation of amylopectin which is responsible for the bread staling4. Dietary fibre in chia can also prolong freshness by keeping the water content in bread7.
In a nutshell, the incorporation of chia as seed, oil or flour improve the nutritional profile of bread by increasing their fibre, protein, minerals, Omega-3, essential fatty acids and antioxidant compounds. It also improves the bread quality by providing better texture with longer shelf life.
