Researcher uses canola to create biodegradable cling wrap

A University of Alberta researcher has found a new use for a canola byproduct, providing potential for diverse markets beyond China.

Canolastraw—the fibrous stalk left in the field after the plant is harvested for its oil—is proving useful in strengthening a plant-based cling wrap developed by Marleny Saldaña, a researcher in food and bioengineering processing.

In a new study, Saldaña and her research team used cellulose nanofibres from canolastraw to make the clear, plastic-like film, which is 12 times stronger than what they’ve already developed from cassava starch. The straw, which has little other use except as bedding for soil nutrients, contains cellulose and lignin, two components that support the canola plant.

Using canola straw this way demonstrates potential value-added options for the crop residue besides obtaining oil and protein from its seed, said Saldaña, who believes her and her team’s discovery to be the first application of its kind.
