New research study converts fruit waste into 100 % natural ingredients

AINIA and Productos Lcteos Romar have entered into a business research collaboration to boost the worthiness of agricultural by-products. The brand new project will dsicover the duo valorise agricultural by-products to get ingredients with improved technological and nutritional properties.

After obtaining citrus, kaki and watermelon waste, the joint projects researchers will make an effort to transform these into valuable ingredients for foods, including dairy desserts, jellies, snacks and toppings.

Listening and giving an answer to food scarcity pressures

The planet population is likely to increase from todays figure of seven billion to over nine billion in 2050, the Organisation for Economic Co-operation and Development (OECD) reports. Therefore, an evergrowing population will probably raise the pressures placed on natural resources supplying energy and food, the OECD continues.

The study duo at the forefront of the new project recognised the globes growing population and the impact of the pressures. The meals supply chain is under great pressure because of limited resources, water scarcity, soil degradation and the impact of climate change, explainedMariana Valverde Belda, Product and Processes Technologies Department at AINIA, talking with Food Navigator on the inspiration behind the brand new project.

Furthermore, estimates show that one-third of the meals produced globally is lost or wasted. Therefore, the necessity to fortify the food system, from production to consumption, to improve food production in a sustainable way while reducing food waste in the supply chain and limiting environmentally friendly impact is needed, added Valverde Belda.

Improving food properties

In todays food industry, there exists a close relationship between consumers diets and health. The study duo saw a nutritious diet could avoid the onset of several diseases, such as for example certain heart diseases, diabetes, as well as cancer, Valverde Belda shared. Because of this, it is very important enhance the nutritional and healthy value of food, Valverde Belda commented.

Centring efforts on nutrition helps it be necessary, AINIA stated, to learn the nutritional and health quality of the starting recycleables also to design production processes that preserve as much of the properties as you possibly can in the ultimate product.

Manufacturers use different ingredients with technological capabilities to accomplish organoleptic properties such as for example texture, viscosity, palatability, unctuousness, stability, creaminess and gelling of certain foods, including dairy desserts or gummies. Starches, carrageenan, gums, sugars and gelatins are types of these technological capabilities.

The duo found it interesting to take into account the selling point of substituting a few of these previous stabilising and texturizing ingredients with the addition of more natural options. Because of this, the researchers proposed using pectins because they offer more naturalness yet support the same technological properties. These pectins could possibly be obtained through the recovery of the agricultural by-products.

We achieve the usage of more 100 % natural ingredients with exactly the same technological properties because the ingredients they substitute, said Valverde Belda. Regarding gummies, the researchers may lightly decrease the usage of sugar and gelatin, with the latter via an animal source.

Concentrating on health insurance and nutrition

Using agricultural by-products to generate nutritional and functional products is really a key focus of the brand new project.We should also concentrate on increasing the nutritional and functional quality of the produced food and on meeting the requirements of consumers, that are increasingly seeking more natural basic products with a confident effect on their health, relayed Valverde Belda.

In this sense, the researchers declare that the VALUS project promotes research targeted at the development of healthier products, implementing circular economy policies concentrating on the seek out alternative resources of ingredients with commercial interest. To do this aim, the researchers chose by-products which are generated at high volumes annually, that can come from agricultural crops and so are good resources of fibre.

Landing on fruit by-products

AINIA and Postres Lcteos Romar used citrus, kaki and watermelon waste as agricultural by-products. The researchers selected these fruits because of the different crops seasonal production patterns.

As these crops are produced at differing times of the entire year, the study duos recovery strategy can be executed continuously through the project and cover the complete annual calendar. The researchers also recognised these crops have high annual production rates and so are important crops from the Valencian Community.

Furthermore, citrus, persimmon or watermelon by-products are interesting resources of carbohydrates, namely pectin, fibre and bioactive molecules, that garner fascination with the meals industry, Valverde Belda said.

To boost the worthiness of the by-products, the researchers will undertake extractive processes under different conditions. These procedures are increasingly being assessed and concentrate on improving the technological properties of the targeted pectins. Through the project, the researchers have suggested a circular economy policy in order to avoid the waste of any by-product which may be generated through the pectin extraction.

Meeting consumer expectations

AINIA and Postres Lcteos Roma remember that the rise of alternative diets, such as for example vegetarian, vegan and flexitarian diets, is forcing the to build up new foods from plant sources, said Valverde Belda.

Therefore, significant effort is required to develop new plant-based ingredients with interesting techno-functional properties such as for example gelling capacity, emulsion capacity, foaming capacity and solubility. These food types must be much like the ones via animal sources with regards to nutritional and technological properties, said Valverde Belda.

However, individuals are increasingly worried about carrying out a healthy and beneficial diet, AINIA states. A lot more individuals are also searching for a balance between their diet and habits, which helps them achieve a powerful disease fighting capability resistant to infections and viruses.

Finding methods to use fruit by-products such as for example citrus, watermelon and kaki and transform them into functional and valuable things that offer nutritional advantages to consumers is highly popular in todays food sector.
