Natural Bioactive Compounds: Toxicity/Safety Concerns
Although synthetic bioactive compounds are approved in many countries for food applications, they are becoming less and less welcome by consumers. Therefore, there has been an increasing interest in replacing these synthetic compounds by natural bioactive compounds. These natural compounds can be used as food additives to maintain the food quality, food safety and appeal, and as food supplements or nutraceuticals to correct nutritional deficiencies, maintain a suitable intake of nutrients, or to support physiological functions, respectively. Recent studies reveal that numerous food wastes, particularly fruit and vegetables byproducts, are a good source of bioactive compounds that can be extracted and reintroduced into the food chain as natural food additives or in food matrices for obtaining nutraceuticals and functional foods. This entry addresses general questions concerning the use of fruit and vegetables byproducts as new sources of natural bioactive compounds that are being addressed to foods as natural additives and supplements. Those bioactive compounds must follow the legal requirements and evaluations to assess the risks for human health and their toxicity must be considered before being launched into the market. To overcome the potential health risk while increasing the biological activity, stability and biodistribution of the supplements’ technological alternatives have been studied such as encapsulation of bioactive compounds into micro or nanoparticles or nanoemulsions. This will allow enhancing the stability and release along the gastrointestinal tract in a controlled manner into the specific tissues. This review summarizes the valorization path that a bioactive compound recovered from an agro-food waste can face from the moment their potentialities are exhibited until it reaches the final consumer and the safety and toxicity challenges, they may overcome.

Therapeutic Potential of Hops
The medicinal potential of hop (Humulus lupulus L.) is widely cited in ancient literature and is also allowed in several official pharmacopoeias for the treatment of a variety of ailments, mainly related to anxiety states. This is due to the plethora of phytoconstituents (e.g., bitter acids, polyphenols, prenyl flavonoids) present in the female inflorescences, commonly known as cones or strobili, endowed with anti-inflammatory, antioxidant, antimicrobial, and phytoestrogen activities. Hop has attracted the interest of the scientific community due to the presence of xanthohumol, whose strong anti-cancer activity against various types of cancer cells has been well documented, and for the presence of 8-prenyl naringenin, the most potent known phytoestrogen. Studies in the literature have also shown that hop compounds can hinder numerous signalling pathways, including ERK1/2 phosphorylation, regulation of AP-1 activity, PI3K-Akt, and nuclear factor NF-κB, which are the main targets of the antiproliferative action of bitter acids and prenylflavonoids.

Extraction Techniques of Bioactive Compounds
Fruit wastes and/or by-products that food agro-industries accumulate are typically made up of underutilized residual biomasses that are rich in various bioactive functional components. Fruit wastes have been researched for the extraction of phenolic compounds, dietary fibers, and other bioactive substances, as they are rich sources of phytochemicals. Fruit and vegetable wastes from the agri-food sector are produced in enormous quantities and, due to their high moisture content and microbial load, can lead to significant environmental damage. Bioactive components could degrade quickly, even with the slightest alterations in extraction techniques. Therefore, it is necessary to ensure conditions that will stabilize the bioactive components before and after extraction. Choosing an appropriate optimized extraction technique is critical as it decides the final quality of the bioactive compound.

Goose Meat as a Source of Dietary Manganese
Manganese is a trace element with essential physiological functions that should be supplied to animals and humans through diet. The primary source of manganese in the human diet is tea and plant products. Diversifying the diet with goose meat is also worthwhile because, unlike plant food, it does not contain substances that diminish bioavailability, such as fiber or phytates. As a natural source of this element, goose meat does not increase exposure to overconsumption, as can happen when consuming dietary supplements. Manganese content of domestic or wild goose meat depends on the type of muscles (more Mn in leg muscles), presence of skin (more Mn in skinless muscles), and thermal treatment (pan fried with oil, grilled, and cooked meat contains more).

Application of Encapsulated Limonene in Agri-Food Industry
Limonene or 4-isopropenyl-1-methylcyclohexene (C10H16) is a monocyclic monoterpene hydrocarbon naturally synthesized in many plants through the cyclisation of geranyl pyrophosphate by a monoterpene synthase. It constitutes one of the most abundant monocyclic monoterpenes in the plant kingdom, being found in more tan 300 essential oils and principally in Citrus spp. (30-98%). The high availability in nature together with its proved safety, make it widely exploitable in health, as flavoring agent and adjuvant in food and beverage industries, as well as in cosmetic’s for the formulation of perfumes and other personal hygiene products. In particular, this compound has been proven to possess a valuable potential as sustainable replacement to synthetic pesticides and food preservatives. To successfully use limonene in a greener agri-food industry, its preservation has become a top concern for manufacturers. In general, encapsulation conserves and protects limonene from outside aggressions, but also allows its controlled release as well as enchances its low water solubility, which can be critical for the target applications, together with other parameters, such as scalability, low cost and availability.
