“…Reducing FLW to shut the gap among the current availability of food and the future demand of food fulfils all the criteria from the social, ethical, economic and environmental point of view: poverty, ecosystem, climate and water. Reducing FLW may be one of a kind multiple ‘win‐win’ strategy (Cheok et al ., ).…”

Waste from fruits and vegetable processing industry is produced in large quantities worldwide and it contains high levels of lignocellulose, fibre, sugar, bioactive and functional compounds. Their utilisation has become one of the main important and challengeable aspects due to the generation of large quantities of by-products including peels, seeds, leaves and unused flesh in different steps of processing chain. Many researches have validated the waste utilisation as novel, low-cost, economical and natural sources of dietary fibre, antioxidants, pectin, enzymes, organic acids, food additives, essential oils, etc. through different methods of extractions, purifications and fermentations. Though, obtaining these by-products from such a variable substrate requires an understanding of the composition of the polysaccharides and their associations within the overall substrate. Focus on the pineapple fruit, scientific and technological studies have already highlighted and confirmed the potential of better and more profitable markets for pineapple wastes. This review is first of all the collection of previous reports about valorisation of food processing waste, deepening the possibilities of pineapple waste utilisation and to promote the integral exploitation of the by-products rich in bioactive compounds, even as multifunctional food ingredients. More in detail, this review aims at identifying those processes that can be implemented even in disadvantaged areas by means of technologies that allow recovering waste directly on site, thus reducing pollution and providing ingredients/food products with high nutritional values that could be integrated into the diet.

“…To date, biowaste products derived from various sources, including fruits have been widely recycled into valuable products ranging from agricultural compost, citric acid production, biofuel, pigment, and bioactive compound production [1]. This recycling method can also effectively resolve Pineapple waste could be a valuable source of important bioactive compounds that have countless beneficial for therapeutic application, including antioxidant, anti-inflammatory and antimicrobial properties [5,6].…”

Pineapple (Ananas comosus) waste is a promising source of metabolites for therapeutics, functional foods, and cosmeceutical applications. This study strives to characterize the complete metabolite profiles of a variety of MD2 pineapple waste extracts. Metabolomics strategies were utilized to identify bioactive metabolites of this variety prepared with different solvent ratios. Each pineapple waste extract was first screened for total phenolic content, 2,2-diphenyl-1-picrylhydrazyl free radical scavenging, nitric oxide scavenging, and α-glucosidase inhibitory activities. The highest TPC was found in all samples of the peel, crown, and core extracted using a 50% ethanol ratio, even though the results were fairly significant than those obtained for other ethanol ratios. Additionally, crown extracted with a 100% ethanol ratio demonstrated the highest potency in DPPH and NO scavenging activity, with IC 50 values of 296.31 and 338.52 µg/mL, respectively. Peel extracted with 100% ethanol exhibited the highest α-glucosidase inhibitory activity with an IC 50 value of 92.95 µg/mL. Then, the extracts were analyzed and the data from 1 H NMR were processed using multivariate data analysis. A partial least squares and correlogram plot suggested that 3-methylglutaric acid, threonine, valine, and α-linolenic acid were the main contributors to the antioxidant activities, whereas epicatechin was responsible for the α-glucosidase inhibitory activity. Relative quantification further supported that 100% crown extract was among the extracts that possessed the most abundant potential metabolites. The present study demonstrated that the crown and peel parts of MD2 pineapple extracted with 100% ethanol are potentially natural sources of antioxidants and α-glucosidase inhibitors, respectively.

“…Recently, a polysaccharide-protein biopolymer has been extracted from the seasonal fruit, durian (Durio zibethinus), known as durian seed gum (DSG). Durian is a popular fruit consumed in South East Asia (Cheok et al, 2018). After consumption of the fruit, the durian seeds which makes up 20-25% of the entire fruit, is thrown away .…”

The search for natural and sustainable biopolymers is increasing. Biopolymers are used in applications, such as to encapsulate and stabilize probiotic bacteria. Currently, this process requires many steps, including the separation of bacteria from the culture media after fermentation, which is energy intensive. In this study, we developed a strategy to use a natural biopolymer from durian seed, durian seed gum (DSG), to address these issues. DSG was used to serve dual roles, firstly as a nutrient source, and secondly as an encapsulating agent. DSG was used in synergy with reconstituted skim milk (RSM), to be a complete nutrient source, for probiotic bacteria Lactobacillus plantarum (L. plantarum). Usually RSM requires supplementation, with costly yeast extract. DSG was characterized to be a suitable nutrient source as it contains polysaccharides, organic acids, amino acids and fatty acids. In the presence of DSG and RSM, the growth of L. plantarum increased from 8.73 log CFU/mL to 13.86 log CFU/mL, at the end of 72 h. In comparison, when grown with commercial gum arabic (GA) and RSM, growth of L. plantarum reached a lower 11.49 log CFU/mL at 72 h. Metabolomics revealed that several metabolites, including lactose, depleted after fermentation, in the DSG and RSM treatment group, as compared to GA and RSM treatment group. This suggested that glycolysis were up regulated. This correlated with the increased growth, lactic acid, malic acid and fatty acids production by L. plantarum when it was grown on DSG and RSM. Next, the entire culture of L. plantarum with DSG and RSM was taken for spray drying, without the need to separate the bacteria from the culture media. DSG and RSM was able to stabilize L. plantarum, to remain viable at 10 log CFU/g after storage for 10 weeks. On the other hand, the viability was 8.8 log CFU/g when L. plantarum was spray dried with GA and RSM. This study demonstrated an innovative process and low-cost strategy to produce spray dried probiotic powder. DSG could be a potential low cost and sustainable replacement for GA, to develop other functional foods.
