Water-based prolamin compositions, methods of making water-based prolamin compositions, and applications thereof

摘要

The invention relates to water-based prolamin (e.g., zein) compositions and to methods of making water-based prolamin compositions. The compositions may be used in paints, printing inks, varnishes, adhesives, glues, binders (e.g., for paper), food coatings, and the like.

主权项

1. A method of making a water-based, flowable zein composition for delivering a zein, comprising:
(A) providing an acidified zein composition comprising
i. a zein comprising α-zein and at least one of β-zein and γ-zein in a total amount of at least about 15% by weight;ii. water;iii. at least one of alcohol and ketone; andiv. acid; and (B) removing at least a portion of the at least one of alcohol and ketone from the acidified zein composition to form a water-based, flowable zein composition comprising water in an amount ranging from at least about 30% by weight to at least about 75% by weight.
