The rising global population has created an urgent need for increased food production. Food loss and waste remain significant challenges throughout the food supply chain, from cultivation to consumption. Blockchain, a decentralized peer-to-peer network that stores information can help making food more traceable, from production to consumption. It can also help enhance food production sustainability, transparenc...
Plant-based beverages are gaining attention due to their potential to offer sustainable and health-promoting alternatives to traditional dairy products. This study aimed to develop a dehydrated functional plant-based beverage composed of tigernut tubers (Cyperus esculentus L.), mukua pulp (Adansonia digitata L.), and thermal water. All matrices and the final beverage were fully characterized in terms of physica...
This investigation evaluates the valorization of citrus peels (lemon, tangerine, and orange) to recover both on-polar and polar fractions simultaneously. Citrus essential oils, abundant in limonene (74.4–33.7 %), exhibited great antioxidant activity (IC50 = 2.002 mg/mL) and Campylobacter jejuni halo inhibition (2.9 cm), particularly in tangerine and orange essential oils. The aqueous extracts were rich in quini...
The aim of this study was to assess the performance and stability of betacyanin compounds present in enriched extracts of red-fleshed pitaya peels (Hylocereus costaricensis) and the flowers of Amaranthus caudatus; they were evaluated as natural food colorants in tagliatelle pasta and meringue cookies. The recovered natural extracts showed promising stability, maintaining a deep pink color over a storage time of...
The fig tree (Ficus carica L.) was one of the first domesticated trees. In 2019, the world's fig fruit production was estimated at 1153 tons. However, fig leaves are not utilized, resulting in copious quantities of bio-waste. To identify promising fig tree varieties, hydroethanolic extracts were prepared from the leaves of five fig tree varieties (Pasteliere-PA, Longue d'Aout-LA, Dauphinie-DA, Boujassote Noire-...
The study of primary plant metabolism has been the main focus of scientists for several years, seconding research related to the secondary metabolism. Nowadays, with the better understanding of the processes and products involved in primary metabolism, the focus has switched to the expansion of knowledge involving secondary metabolism. Initially, plants were the focus of secondary metabolite studies due to thei...
The 17 goals of sustainable development address several topics, such as: (2) Zero hunger and sustainable agriculture; (9) Industry, Innovation, and Infrastructure; (12) Responsible consumption and production; that are essential for the promotion of the circular economy, product development and conscious production [1]. Fig is a food matrix, cultivated in Portugal and valued by the Portuguese people for consumpt...
Hylocereus costaricensis peel contains large amounts of betacyanins and can be exploited as a source of natural colorants. This work aimed the chemical characterization and evaluation of bioactive properties of this byproduct and the optimization of the ultrasound-assisted extraction (UAE) of betacyanins using the response surface methodology (RSM). Oxalic and malic acids and traces of fumaric acid were detecte...
The vibrant colours of many plants are due to secondary metabolites, such as nitrogen-containing compounds, where betacyanins are included. These compounds can be found in plants such as Amaranthus caudatus L. that, due to their high nutritional benefits, have been overproduced, which leads to the accumulation of large amounts of bio-residues. Among these bio-residues, the flowers which have a very intense pink...
Wild plants have received high importance at different locations and times of the human history given their ability to provide nutrients and protection[1]. In the Northeastern region of Portugal, a mountainous land with a vast biodiversity and cultural heritage, a large number of edible wild plants have become underutilized over time. This abandonment was mainly due to altered lifestyles of the modern society a...
