General Properties and Industrial Significance:
Citrus Peel Oligosaccharides (CPOs) are short-chain carbohydrates derived from the breakdown of pectin, a natural polysaccharide abundant in citrus peels. These oligosaccharides are gaining attention for their potential health benefits, particularly in supporting gut health.
Citrus Peel Oligosaccharides improve fertilizer absorption and conversion, enhance crop stress resistance, promote roots and seedlings, promote color transformation and increase sugar content, and improve quality and yield.
Source: Extracted from the peels of citrus fruits such as oranges, lemons, and grapefruits.
Composition: Comprise various sugar units, including arabinose, galactose, and galacturonic acid, forming short-chain oligosaccharides.
Extraction: Typically produced through enzymatic hydrolysis or hydrothermal treatment of citrus peel waste.
Applications:
-
Prebiotic Effects
-
CPOs serve as prebiotics, substances that promote the growth and activity of beneficial gut bacteria. Studies have demonstrated that CPOs can:
-
Enhance the growth of beneficial species like Faecalibacterium prausnitzii.
-
Increase gut microbiota diversity.
-
Stimulate the production of short-chain fatty acids (SCFAs), such as butyrate, which are beneficial for colon health .
-
Gut Health Support
-
By promoting a healthy gut microbiota, CPOs may contribute to:
-
Improved digestion and nutrient absorption.
-
Enhanced immune function.
-
Potential relief from gastrointestinal disorders.
-
Sustainable Ingredient
-
Utilizing citrus peel waste to produce CPOs aligns with sustainable practices by:
-
Reducing food waste.
-
Converting agricultural by-products into valuable functional ingredients.
