- *Abstract
-
Fruit-processing residues, called pomace, account for 25 - 40% of total fruits processed, and liquid whey, a byproduct of dairy processes such as Greek style yogurt, represent a relatively untapped source of ingredients from which to create novel and nutritious food products.
Cornell researchers combined pomace and liquid whey and extruded the mixture using low-shear, low-temperature supercritical fluid extrusion (SCFX), retaining a higher level of phytochemicals and antioxidants found in the pomace. Additionally, fruit pomace added dietary fiber and improved upon the textural quality.
By use of economical and versatile extrusion technology, the resulting new food is nutritious, high in protein, and contains bioactive ingredients. It offers a potential of a long shelf-life and can be consumed without preparation.
Potential Commercial Applications:
- Unique combination of agro-industry byproducts to create new products of value, such as: ready-to-eat, puffed nutritious snack product and breakfast cereal, as well as to enhance the nutritional value of current extruded foods.
Potential Advantages
- Recaptures the value and health benefits of two important food byproducts.
- Retains nutrients, unlike high temperatures processing, which reduces nutritional quality.
- Use of liquid whey eliminates the energy intensive step of drying that destroys the nutritional qualities of whey.
- Stable at room-temperature and has potential for a long shelf-life.
- High in antioxidants and phenolics.
- A healthful and convenient snack food.
