Recent rapid growth of the world's population has increased food demands. This phenomenon poses a great challenge for food manufacturers in maximizing the existing food or plant resources. Nowadays, the recovery of health benefit bioactive compounds from fruit wastes is a research trend not only to help minimize the waste burden, but also to meet the intensive demand from the public for phenolic compounds which are believed to have protective effects against chronic diseases. This review is focused on polyphenolic compounds recovery from tropical fruit wastes and its current trend of utilization. The tropical fruit wastes include in discussion are durian (Durio zibethinus), mangosteen (Garcinia mangostana L.), rambutan (Nephelium lappaceum), mango (Mangifera indica L.), jackfruit (Artocarpus heterophyllus), papaya (Carica papaya), passion fruit (Passiflora edulis), dragon fruit (Hylocereus spp), and pineapple (Ananas comosus). Highlights of bioactive compounds in different parts of a tropical fruit are targeted primarily for food industries as pragmatic references to create novel innovative health enhancement food products. This information is intended to inspire further research ideas in areas that are still under-explored and for food processing manufacturers who would like to minimize wastes as the norm of present day industry (design) objective.

Malaysia produces varieties of tropical fruits such as durian, rambutan, jackfruit, mango, papaya, and mangosteen but the seeds are considered waste. The seeds contain beneficial nutrients such as protein, carbohydrates, fat, and minerals, and have high bioactive properties. Various processing methods have been applied to extract the seeds and apply them to the food system. The information is scattered and incomprehensive, therefore, this paper aims to review the chemical properties and biological activities of the selected tropical fruit seeds, and their processing and functional properties to the food. Most seeds are rich in carbohydrates but also contain various minerals and fatty acids. The antioxidant, antidiabetic, anti-bacterial/anti-fungal, anti-inflammatory, anti-hyper cholesterol and anti-proliferative properties were also reported with rambutan and papaya seeds having the most bioactive properties. Novel and conventional extraction methods of the seeds, the functionality of the seeds to improve the food such as pasting and emulsifying properties, and their effect on the colour, texture, sensory and storage stability were also highlighted. In summary, all the selected seeds have the potential to be upcycled as food ingredients as they contain various nutrients while providing therapeutic and functional properties, however, further research can be considered to optimize the seeds' usability.

Highlights: [•] Edible coatings were used for fresh-cut pineapple during low temperature storage. [•] Alginate-based coating incorporated with 0.3% lemongrass was the best formulation. [•] This formulation has potential to extend the shelf life and maintain the quality. [•] Lemongrass (0.5%) had negative effect on taste and firmness of coated samples. [ABSTRACT FROM AUTHOR]
