The common breakfast bread has been elevated to a nutrient-packed wheat
product by scientists at Jadavpur University, who decided to go green
and fortify it with coriander.
"We have studied the effects of
supplementing the general bread flour with herbs such as coriander which
has had a substantial effect in improving shelf life and nutrient
levels," Utpal Raychaudhuri, a senior scientist at the university's
Department of Food Technology and Biochemical Engineering, told IANS.
Lipi
Das and Runu Chakraborty were the other members of the research team
whose findings - published in the Journal of Food Science and
Biotechnology - showed that coriander remarkably delayed the bread's
going stale, while the microbicidal (germ-killing) property of the herb
added to its shelf life.
Coriander (Coriandrum sativum L.
Umbelliferae) is considered both a herb and a spice, since both its
leaves and seeds are used for seasoning. In India, it is known as
'dhania'. The leaves, stem, roots, and seeds of natural herbs are rich
in minerals, micronutrients, antioxidants, dietary fibres and essential
oils which may have microbial properties against food-borne pathogens
such as the Salmonella species.
The shelf life of bread is influenced by mainly two factors - going stale and microbial deterioration.
"In
this novel study, dried and powdered coriander leaves were incorporated
into raw materials for baking bread such as wheat flour, sugar,
shortenings (refined vegetable oils), salt and compressed baker's
yeast," Raychaudhuri explained.
For comparison, a control was also baked which had no coriander supplement.
The
final product, which had an attractive light green hue and powder leaf
content between 3-5 percent of the weight of wheat flour was found to be
the optimum supplementation level. Moreover, the coriander supplement
helped retain moisture and improved the quality of the bread.
In
terms of nutrients, antioxidants, which delay ageing and fight cancer,
shot up by 50 percent in coriander-fortified bread as opposed to the
unfortified sample.
Overall, the bread tasted better and the pleasant herbal aroma added to its appeal.
When
it comes to fortified bread items like garlic, cheese, rice flour, corn
flour, soy flour, cowpea, bengal gram, flaxseed, and fenugreek have
been used as supplements.
Coriander-fortified common white bread will be a welcome addition to the genre.
