TITLE:

Evaluation of freeze-dried and spray dried acerola and jambolan residues: process life cycle assessment and final product characterization - physicochemical, bioactive and bioaccessibility assessment.

KEY WORDS:

SUMMARY:

Brazil is a country of great biodiversity with tropical fruits of high economic value and, others still underexploited. While acerola has a well stablished market, jambolan is an underexploited fruit. Both residues present high bioactive concentration and will be studied in the present research. In fact, the residues represent up to 10-30% of the fruit weight, and contain biomolecules of economic value that are still underused. It is expected that proper management of these residues can generate food products with functional potential by using drying techniques such as freeze-drying and spray drying to expand their market value and and add value to this agricultural raw material. In this regard, the use of ultrasound for extract preparation is reported to increase the extraction of bioactive compounds and improve drying. Furthermore, assessing drying processes for environmental impact is of great importance for the development of environmentally friendly processes, and can be assessed by tools such as Life Cycle Assessment (LCA). Therefore, the present doctoral project aims to study the use of acerola and jambolan residues with the use of freeze-drying and spray drying and will be conducted according to the following stages. i) Evaluation the use of ultrasonic extraction to enhance bioactive extraction that will be further dried; ii) application of the Life Cycle Analysis tool and compare the techniques regarding energy consumption; iii) study the final product regarding its bioactive, functional characteristics and bioaccessibility.
