Project overview

 

The central goal of our project is to enhance the nutritional value of children's food, including yoghurts and desserts, by incorporating bioactive compounds (BACs) derived from Moringa oleifera leaves. 

Among the chemical components found in various parts of moringa, polyphenols, particularly phenolic acids and flavonoids, hold a crucial role as antioxidants. Additionally, in our pursuit to combat malnutrition, we are focusing on other essential BACs previously identified in Moringa oleifera, including amino acids, vitamin C and vital mineral salts, like calcium and potassium.

Our project unfolds through the following key objectives:

  1. Advancing our understanding of the key bioactive compounds within extracts from different parts of Moringa oleifera, often referred to as the "miracle tree."
  2. Employing environmentally friendly and sustainable extraction and separation techniques to achieve selective extraction via membrane separation.
  3. Extending the shelf life of extracts using microencapsulation to prevent BAC degradation.
  4. Incorporating microcapsules containing bioactive compounds into widely consumed children's food.
  5. Evaluating the health impacts of these new functional foods to ensure food security.

To extract the target BACs, we will primarily use Moringa leaves collected from two different locations in Luanda (Angola), following a suitable sampling method that considers factors such as plant age, soil characteristics, and climate. Chemical characterization of these samples, focusing on the compounds, will be carried out using diverse analytical techniques based on colorimetry and chromatography.

To attain extracts rich in the desired BACs, we will conduct experimental tests that combine solvent extraction with a filtration process using nanofiltration membranes. Microencapsulation techniques will be applied to safeguard the stability of the extracted compounds.

Our research also includes investigations into encapsulation efficiency, controlled release of BACs, and fortification of selected food products for school children, alongside sensory acceptability tests.

2-Participation in national and international events

International Conference on Water, Energy, Food and Sustainability (ICoWEFS 2023): Oral presentation given by fellow Olívia Gomes at the ICoWEFS conference, in Leiria (Portugal), with a paper entitled “Extraction of Moringa oleifera leaves to obtain antioxidants and vitamins”.

 

 

European Researchers' Night 2023: Divulgation of the objectives of the MorFood project carried out by scholarship holder Olívia Gomes at the European Researchers' Night, in Coimbra (Portugal).

 

 

 

 

 

3-Sensory analysis of fortified chocolate mousse

 

 

In the context of the MorFood project, a sensory analysis session was held on chocolate mousse fortified with biocompounds from Moringa oleifera leaves, in the Department of Chemical Engineering, University of Coimbra (Portugal). The work carried out by researcher Olivia Gomes aims to fortify foods with vitamins and minerals, to mitigate child malnutrition.

Outcomes

 

1 – Growth of Moringa oleifera plantations in Angola
2 – Dissemination of the results in international scientific journals
