Evaluation of extraction method on the structure and physicochemical properties of starch from seeds of two jackfruit varieties
(2017-11-01)
Two main varieties of jackfruit (soft and hard) are commonly known in Brazil and contain a large amount of starch. This work aimed to evaluate the effect of extraction methods (aqueous and alkaline treatments) on the ...
Effect of different chemical treatments on nutritional and antinutritional properties of coffee pulp
(Elsevier, 2002)
Different chemical treatments were tested to improve the nutritional value of coffee pulp (CoP):
(1) alkali, NaOH solutions of 5 and 10% for 24 and 48 h; (2) a combination of acid and alkali, with
