Gelatinous food elastomer compositions and articles for use as fishing bait

This invention describes a soft, stretchy fishing bait. It's made by mixing a rubber-like plastic material with food ingredients and a large amount of softening agent (plasticizer). The plasticizer is crucial, making up at least 250 parts for every 100 parts of the rubber, to give the bait a specific squishy texture that fish will bite.

Why it matters: Since 2002, advancements in polymer science have introduced a wider range of thermoplastic elastomers and plasticizers, potentially making it easier and more cost-effective to achieve the specific gel rigidity and controlled attractant release described. The ability to precisely tailor material properties for scent dispersal in artificial baits has also improved.
