Utilization of pomace from apple processing industries: a review

Area of Science:

• Food Science
• Agricultural Engineering
• Environmental Science

Background:

• Apple juice production generates substantial apple pomace (25% of raw apple material).
• India produces ~1 million tons of apple pomace annually, with only ~10,000 tons utilized.
• Unutilized apple pomace contributes to environmental pollution.

Purpose of the Study:

• To review existing research on apple pomace utilization.
• To highlight the potential of apple pomace as a valuable resource.
• To encourage the development of small-scale industries based on apple pomace.

Main Methods:

• Literature review of scientific publications on apple pomace.
• Analysis of nutritional composition and properties of apple pomace.
• Exploration of potential applications and conversion technologies.

Main Results:

• Apple pomace is rich in carbohydrates, pectin, crude fiber, and minerals.
• It possesses significant potential for conversion into various edible products.
• Current utilization rates are critically low, indicating a missed opportunity.

Conclusions:

• Apple pomace represents a valuable, underutilized resource from the apple industry.
• Its rich nutritional profile supports its conversion into diverse products.
• Promoting apple pomace utilization can mitigate environmental pollution and foster economic development through small-scale industries.
