Summary
Grape seeds from winemaking byproducts can be utilized to extract valuable bioactive compounds for food, cosmetics, and pharmaceuticals. This biorefinery approach supports a circular economy by also enabling energy production from the remaining biomass.
Area of Science:
- Biorefinery and Circular Economy
- Sustainable Chemistry
- Food Science
Background:
- Food and agricultural waste poses significant economic, environmental, and health challenges.
- Winemaking generates valuable byproducts, such as grape seeds, with potential for high-value applications.
- Current waste management strategies often overlook the potential for resource recovery and valorization.
Purpose of the Study:
- To explore the extraction of bioactive compounds from grape seeds within a biorefinery framework.
- To evaluate the potential of grape seed biomass for energy production (biohydrogen and biomethane).
- To present an overview of Italian experiences in valorizing wine industry byproducts.
Main Methods:
- Review of green and sustainable extraction techniques for bioactive compounds.
- Integration of emerging analytical techniques and chemometrics for component investigation.
- Discussion of innovative technologies and pilot-scale process developments for enhanced extraction yields.
Main Results:
- Grape seeds contain high-value bioactive compounds applicable to food, cosmetic, and pharmaceutical industries.
- The remaining biomass can be utilized for energy generation, including biohydrogen and biomethane.
- Advanced extraction and analytical methods are crucial for optimizing yield and purity.
Conclusions:
- Valorizing grape seeds aligns with biorefinery and circular economy principles, transforming waste into valuable resources.
- Multidisciplinary approaches and sustainable technologies are key to unlocking the full potential of wine industry byproducts.
- The Italian experience demonstrates the feasibility and benefits of implementing such integrated waste valorization strategies.

Seed structures are composed of a protective seed coat surrounding a plant embryo, and a food store for the developing embryo. The embryo contains the precursor tissues for leaves, stem, and roots. The endosperm and cotyledons—seed leaves—act as the food reserves for the growing embryo.

All living things are formed mostly of carbon compounds called organic compounds. The category of organic compounds includes both natural and synthetic compounds that contain carbon. Although a single, precise definition has yet to be identified by the chemistry community, most agree that a defining trait of organic molecules is the presence of carbon as the principal element, bonded to hydrogen and other carbon atoms. However, some carbon-containing compounds such as carbonates, cyanides, and...

In most main group element compounds, the valence electrons of the isolated atoms combine to form chemical bonds that satisfy the octet rule. For instance, the four valence electrons of carbon overlap with electrons from four hydrogen atoms to form CH4. The one valence electron leaves sodium and adds to the seven valence electrons of chlorine to form the ionic formula unit NaCl (Figure 1a). Transition metals do not normally bond in this fashion. They primarily form coordinate covalent bonds, a...

Pure substances consist of only one type of matter. A pure substance can be an element or a compound. An element consists of only one type of atom, while a compound consists of two or more types of atoms held together by a chemical bond.
Elements
Elements are classified as atomic or molecular based on the nature of their basic units. They are unique forms of matter with specific chemical and physical properties that cannot break down into smaller substances by ordinary chemical reactions. There...
