The Opuntia ficus indica (L.) (OFI) is used as a nutritional and pharmaceutical agent in various dietary and value added products. This study underlines the possible use of native prickly pear cladode powder as a functional ingredient for health-promoting food production. To summarise, chemical characterization of polyphenols, minerals and soluble dietary fibre was performed; furthermore, the antioxidant activity and bioaccessibility of polyphenols and minerals were assessed. Eleven compounds between phenolic acids and flavonoids were identified, with piscidic acid and isorhamnetin derivatives being the most abundant. Opuntia’s dietary fibre was mainly constituted of mucilage and pectin, and was composed of arabinose, galactose, glucose, mannose, rhamnose, and xylose sugars. The polyphenols’ bioaccessibility was very high: piscidic acid at 200%, eucomic and ferulic acids >110% and flavonoids from 89% to 100%. The prickly pear cladode powder is also a source of minerals, as cations (calcium, sodium, potassium and magnesium) and anions (sulphate and chloride), with high magnesium bioaccessibilty (93%). OFI powder showed good capacity of radical scavenging measured by DPPH and ABTS methods, with 740 and 775 μmol Trolox/100 g OFI, respectively. Finally, the presented results allow the consideration of this natural product as a source of several essential nutrients, with a possible use in the food industry as a functional ingredient.

Owning to the increase in the world population as well as the consumer’s awareness on the health benefits of consumption of fruits, the demand for both fresh and processed fruits has been increased. The by-product and waste streams generated from fruit processing industries are extremely diverse, owning mainly to different fruits varieties and the wide range of the processes employed towards the production of the end fruit-based products. Due to the increasing production and processing of fruits, disposal of waste and by-product streams has become a serious issue, since these materials are prone to microbial spoilage. Also, the inappropriate waste management practices pose severe environmental issues. Furthermore, the costs of drying and storage of fruit processing residues are economically limiting factors hindering their further exploitation. Therefore, fruit processing by-products such as peels, seeds and unused flesh are often utilized as fertilizers. On the other hand, plant residues contain biomolecules such as vitamins, proteins, minerals, antioxidants and aromatic oil. Recovery of bioactive compounds holds a great potential for their usage in food industry as functional ingredients and nutraceuticals or in pharmaceutical and in cosmetic applications. So, valorization of plant fruit processing by-products to high-value added compounds, constitute a promising alternative not only for addressing fruit residues management issues but also leading to the production of functional food products of high nutritional value, with several potential beneficial health effects. The aim of this paper is to highlight current trends in addressing environmental issues caused by the production of high volumes of specific categories of fruit processing waste streams by investigating their potential usage as natural raw materials for the recovery of valuable bioactive compounds (such as polyphenols, dietary fibers or aromatic oil). The extracted nutrients may be used in the industrial food sector for the production of functional foods, nutraceuticals or even as health promoting natural pharmaceutical ingredients or additives for the production of innovative enriched foods. </p><p> Highlights: • Fruit processing by product streams are rich in bioactive compounds. </p><p> • Integration of fruit by-products and waste streams to value added products such as additives, unconventional oil, bioactive compounds and novel functional products is a very interesting approach regarding fruit processing residues exploitation. </p><p> • Recovering of biomolecules from fruit residues by non-thermal processes could lead to the efficient production of highly purified functional ingredients. </p><p> • Negative-valued fruit processing residues could be recycled for the production of health promoting value added products.

Biosynthetic capabilities of microbes have solved several hurdles in the human welfare. Microbes have served and continue to serve as imperial candidates in both production and management strategies. Microbe mediated techniques has emerged as ecofriendly and sustainable alternative to their synthetic counterparts. Fruit based industries produces large volumes of solid and liquid wastes contributing to increase in pollution load. Disposal of these waste not only represent loss of valuable biomass but also leads to substantial increase in Biological Oxygen Demand (BOD) and Chemical Oxygen Demand (COD). However, in spite of their pollution and hazard aspects, in many cases, fruit processing wastes have a promising potential for being chief raw materials for secondary industries. This chapter summarizes microbe mediated fermentative utilization of fruit waste, for the production of value added products like organic acid, single cell protein, bioplastics, enzymes and biogas.

The modern linear agricultural production system allows the production of large quantities of food for an ever-growing population. However, it leads to large quantities of agricultural waste either being disposed of or treated for the purpose of reintroduction into the production chain with a new use. Various approaches in food waste management were explored to achieve social benefits and applications. The extraction of natural bioactive molecules (such as fibers and antioxidants) through innovative technologies represents a means of obtaining value-added products and an excellent measure to reduce the environmental impact. Cosmetic, pharmaceutical, and nutraceutical industries can use natural bioactive molecules as supplements and the food industry as feed and food additives. The bioactivities of phytochemicals contained in biowaste, their potential economic impact, and analytical procedures that allow their recovery are summarized in this study. Our results showed that although the recovery of bioactive molecules represents a sustainable means of achieving both waste reduction and resource utilization, further research is needed to optimize the valuable process for industrial-scale recovery.

This study aimed to evaluate 69 Capsicum accessions from the Germplasm Bank of Universidade Federal de Roraima, for some fruit quality traits. The experiment was performed in a completely random design, with 69 treatments and 3 replications. The 69 accessions were evaluated for fourteen quantitative and two qualitative traits of ripe fruits. Quantitative fruits data were subjected to an analysis of variance, and the means were grouped by Scott-Knott test (p<0.01). All characteristics had significant effect of treatments (p<0.01) for all evaluated traits. The data showed high genetic variability to future use in a Capsicum breeding program. The accessions 33, 44 and 41 showed major values for dry matter content and total soluble solids; these should be used to improve these traits in a paprika breeding program. On the other hand, the accession 48 showed major values for fresh weight, major fruit length and fruit width. The accession 33, belonging to the Capsicum frutescens species, with high vitamin C content should be used in a fresh market Capsicum breeding program.
