Converting avocado seeds into a ready to eat snack and analysing for persin and amygdalin.

Avocado seeds account for 13% of the waste from industrial production of cold-pressed avocado oil (CPAO). Therefore, the aim of this study was to valorise avocado seeds by converting it into an extruded snack product using a friction cooker and comparing their textural and physical characteristics to extruded brown rice and malted barley ready to eat (RTE) snacks. Concentration of toxins; amygdalin and persin were compared in extruded avocado seed and fresh avocado seeds.

Optimising the Spray Drying of Avocado Wastewater and Use of the Powder as a Food Preservative for Preventing Lipid Peroxidation.

Avocado wastewater (AWW) is the largest by-product of cold pressed avocado oil. The aim of this study was to valorise AWW by converting it into spray dried powder for use as a lipid peroxidation inhibiting food preservative. To increase the powder yield of AWW, addition of carriers and spray drying parameters (temperature and feed flow rate) were optimised.

Converting industrial organic waste from the cold-pressed avocado oil production line into a potential food preservative.

The production of commercial cold pressed avocado oil (CPAO) generates large quantity of organic wastes such as pomace, seeds, peels and wastewater. During the early harvest season, for every 1000 kg of avocado fruits processed, roughly 80 kg of oil is produced and wastewater accounted for the highest proportion (500 kg). Therefore, it is important to find an alternative application for this wastewater rather than its direct disposal into landfills.
