Study Notes
Starch Market and Applications
- The global starch market is valued at approximately USD 60 billion (134.5 million metric tons) in 2022, and is expected to reach USD 90 billion (200 million metric tons) by the end of the third decade.
- Starch is primarily derived from cereals like maize, wheat, and rice, as well as potatoes and cassava.
- The growing demand for starch is driven by its functional properties, which are beneficial in food processing and other industries.
- Over 60% of the global starch market is used in food production.
- Other key markets include animal feed, medicines, dietary supplements, paper, textiles, and biodegradable packaging.
Starch Modification Techniques
- Starch modification techniques like crosslinking, esterification, and etherification are used to enhance its properties.
- Modified starch is expected to see increased demand in the coming years compared to native starch.
- Common solvents for starch functionalization include supercritical carbon dioxide (scCO2), dimethyl sulfoxide (DMSO), and imidazolium ionic liquids (ILs).
- Ionic liquids (ILs) are used as solvents, catalysts, and plasticizers in starch modifications.
- Imidazolium ILs are frequently used in starch modifications due to their stability, designability, and catalytic properties.
- The use of ionic liquids in starch modification is facing limitations due to concerns about their ecotoxicity, hygroscopicity, and potential inactivation of biocatalysts.
Resistant Starch Production
- Resistant starch (RS) is a type of starch that is not digested in the small intestine and acts as a prebiotic.
- It can be classified into four types (RS1-RS4), based on its structure.
- Several processes, including retrogradation, crosslinking, and extrusion, are used to produce RS from different starch sources.
Maltodextrin Esterification
- Maltodextrin esters are non-ionic surfactants produced by esterification of maltodextrin with fatty acids.
- These esters are used as emulsion stabilizing particles in the food industry due to their amphiphilic character.
- Lipase enzymes are used to catalyze the esterification process of maltodextrin with fatty acids.
- The esterification process can be conducted under milder conditions compared to traditional chemical methods.
- Maltodextrin esters have shown antimicrobial properties against various bacteria and fungi commonly found in food products.
