Abstract
The present disclosure is directed to the prevention of spoilage of agricultural products (e.g., tuberous roots such as cassava roots). The disclosure teaches the use of a sulfur-donating compound (e.g., a thiosulfate salt such as sodium thiosulfate) to enable the agricultural product to scavenge endogenously-produced HCN, prevent the buildup of reactive oxygen species, prevent the buildup of insoluble byproducts, and/or prevent the loss of starch from the agricultural product.
Claims23
-116. (canceled)
A method for reducing physiological deterioration of an agricultural product, the method comprising:
- cutting a portion of the agricultural product to expose a cut surface of the agricultural product;
- and
- treating the cut surface of the agricultural product with a sulfur-donating compound to reduce a concentration of reactive oxygen species in the agricultural product.
An edible sulfur-donating composition for application to a surface of an agricultural product, comprising:
- a sulfur-donating compound;
- and
- a diluent for dissolving the sulfur-donating compound therein forming the edible sulfur-donating composition;
- wherein the edible sulfur-containing composition, when applied to the agricultural product, reduces a concentration of reactive oxygen species in the agricultural product.
A method for extending the shelf-life of an agricultural product, the method comprising:
- cutting a portion of the agricultural product to expose a cut surface of the agricultural product;
- and
- treating the cut surface of the agricultural product with a sulfur-donating compound to reduce a concentration of reactive oxygen species in the agricultural product.
