Periodic Reporting for period 2 - UP4HEALTH (Sustainable and cost-effective production process for the upcycling of olive, grape and nut by-products into 4 natural and healthy ingredients for nutraceutical and cosmetic applications)
Reporting period: 2021-12-01 to 2023-05-31
In a current scene of limited resources, million tons of food waste and by-products are discharged worldwide by the food processing industry, whose management is costing EU 143 billion € . In particular, olive and grape by-products account for more than 9.3 million tonnes (Mt). This underexploited residual biomass is rich in bioactive compounds, resulting in a great market opportunity for the UP4HEALTH project. Although existing technologies are promising for the recovery of high added-value ingredients inside the food chain, products from the valorisation of food by-products are still rather limited in the market. The main challenge is to validate an appropriate business model for the affordable upgrading at large scale of a wide variety in composition of by-products from the food processing industry, overcoming bottlenecks like logistic issues and investment costs.
UP4HEALTH upcycling process integrates a unique ZERO WASTE sustainable process for 3 locally available Mediterranean feedstocks from food processing (olive pomace, grape pomace and olive pits) to deliver FOUR ORGANIC, NATURAL, SUSTAINABLE & HEALTHY INGREDIENTS: (1) natural fruit water rich in polyphenols, (2) polyphenol-rich dietary fibre (hereafter referred as “fibre”), (3) fruit natural oily extracts (hereafter referred as “oily extracts”), and (4) prebiotic Xylooligosaccharides (hereafter referred as “XOS”). UP4HEALTH ingredients will be integrated into functional food, nutraceutical supplements and cosmetics, targeting a wide niche population (e.g. elderly people, healthy and green consumers, sporty people…).
The aim of UP4HEALTH is to develop new bio-based SPECIALTY INGREDIENTS (in particular functional ingredients with biofunctional and technological ingredients) from plant-based food processing by-products for high-end markets. UP4HEALTH will allow bringing to market healthier and more sustainable food, supplements and cosmetics under a circular economy concept to satisfy market demand, while giving and added value to underexploited food waste
ISA has access to > 100 tons/year of olive pomace, 100 tons/year of grape pomace and 20 tons/year of nuts by-products during the project implementation for UP4HEALTH production process optimization and for functional ingredient provision to end users. The nutritional and functional characterization of the raw material showed high antioxidant potential due to the high amounts of tyrosol, hydroxytyrosol, oleocanthal polyphenols. These assessments were important for the selection of the best functional ingredients, such as olive pulp powder, olive pulp extract and XOS from olive crushed pits, to be encapsulated and included into the final products. Toxicological analyses were carried out by IPB-CIMO to verify the safety of olive by-products used as raw materials.
These ingredients have been integrated into various food matrices, including meat, oil, yogurt, snack bars, biscuits, smooth food and drinkable gels. Evaluations of properties such as solubility, emulsification, viscosity, flavor, and odor have been conducted to validate their stability and organoleptic characteristics.
The UP4HEALTH project was showcased to stakeholders such as the Irish Government Education Committee and the Northern Ireland Department of Agriculture, Environment and Rural Development.
Finally, a review article entitled, “New Approach Methodologies (NAMs) for safety testing of complex food matrices: A review of status”, considerations, and regulatory adoption” was submitted and accepted
The UP4HEALTH project is setting the basis for 7 new bio-based value chains in the OLIVE BY-PRODUCT LINE and 5 new bio-based value chains in the GRAPE BY-PRODUCT LINE. In total 12 sustainable and locally routed new bio-based value chains are still planned. The functional ingredients to be obtained in UP4HEALTH can be used in different application fields thanks to the purification levels reached in the downstream processing giving 8 products in the nutraceutics sector (functional food: meat, snack bars, smoothfood, drinkable gel, olive oil, natural beverages, yogurt and dietary supplements) and 1 product in the cosmetics sector that meet current market requirements.
UP4HEALTH supports the transition from a linear to circular economy to bring to market healthier nutraceutics and cosmetics, where unavoidable residues produced during food manufacturing in olive oil and wine sectors (30% loss of total production) are viewed as useful resources for production of bioactive compounds.
UP4HEALTH will contribute to food systems more productive, more resource-efficient, more resilient, and less wasteful therefore enhancing ecosystem services.
Regarding the socio-economic impacts of the project: wineries and olive mills will enhance their competitiveness due to savings in logistic and treatment costs associated to the waste management. In addition, versatile and efficient processing technologies posed in UP4HEALTH allows the UPCYCLING COMPANIES that convert food feedstock in high value ingredients, to handle a wide range of raw materials, according to local agricultural practices and seasonal availability. UP4HEALTH will contribute to creating dynamic and competitive regional economies since UP4HEALTH biorefinery will operate locally (use of local biomass) and enable growth at all European regional levels, since the biomass used is available in large quantities in Europe (durable ingredient supply).
