Under the optimal conditions of sequential enzymatic treatment, gliadin was almost completely removed, resulting in the flour extract showing lowest IgE-binding.
Buzzini and Martini (2000) investigated the production of carotenoids by strains of Rhodotorula glutinis on different raw materials of agro-industrial origin (grape must, glucose syrup, beet molasses, soybean flour extract, maize flour extract).
According to electrophoresis assay, the kafirins tert-butanol extract showed a high proportion of α-kafirin monomers, and its amino acid composition revealed higher hydrophobic amino acid content such as alanine, isoleucine, leucine, tyrosine and phenylalanine than sorghum flour extract.
A reason to do so is that both ground rice seeds flour and extracted rice flour proteins contain a mixture of components.
A relationship between antioxidant activity, β –glucosidase and total phenolic content in pineapple peel/soy flour extracts has been reported [10].
An affinity purified trypsin inhibitor from the seed flour extracts of Madhuca indica (MiTI) on denaturing polyacrylamide gel electrophoresis showed that MiTI consisted of a single polypeptide chain with molecular mass of ~19.8 kDa.
Moreover it is the only possible approach for the quantification of trait purity in materials not formed of discrete particles (derived products, e.g. flour, extracts, etc)., as it could be in the next future for high value products derived from "pharma crops", or for the preparation of pure reference materials.
Fortunately for the manufacturers of your chocolate cream dessert, there is a Plan B. They can remove all three offending items, and replace them with a more sophisticated type of "functional flour", hydrothermally extracted from cereals, that will do the same job, but without the need for E numbers.
In order to eliminate the phenolic compounds, the flour was extracted at pH 5 with extractor solutions: 70 mL/100 mL ethanol, 0.1 g/100 mL sodium bisulfite and a 70 30 mixture of the two.
Powdered samples (10 g) of unfermented and fermented soybean flour were extracted with an 80% aqueous methanol solution (1 : 10; w/v) under agitation for 2 h at room temperature.
