The processing of fruits results in high amounts of waste materials such as peels, seeds, stones, and oilseed meals. A disposal of these materials usually represents a problem that is further aggravated by legal restrictions. Thus new aspects concerning the use of these wastes as by-products for further exploitation on the production of food additives or supplements with high nutritional value have gained increasing interest because these are high-value products and their recovery may be economically attractive. It is well known that by-products represent an important source of sugars, minerals, organic acid, dietary fibre and phenolics which have a wide range of action which includes antitumoral, antiviral, antibacterial, cardioprotective and antimutagenic activities. This review discusses the potential of the most important by-products of apple, grape and citrus fruits processing as a source of valuable compounds. The relevance of this topic is illustrated by a number of references.

Citrus reticulata Blanco is a moderately-sized fruit tree widely used as herbal medicine worldwide. The nutritional composition, medicinal uses, phytochemistry and pharmacological properties of C. reticulata were critically reviewed in the current study. The literature linked to C. reticulata properties was obtained from multiple internet sources including Elsevier, Google Scholar, SciFinder, Web of Science, Pubmed, BMC, Science Direct, and Scopus. Ethnopharmacological research identified antioxidants such as vitamin C, carotenoids and phenolic compounds, also a source of sugars, organic acids, amino acids, pectins, minerals and volatile organic compounds as components of C. reticulata. As a medicinal plant, C. reticulata is used for the treatment of dyspepsia, gastro-intestinal distension, cough with profuse phlegm, hiccup and vomiting. The crude extracts of C. reticulata fruits have depicted anti-inflammatory, anticholesterolemic, analgesic, antiasthmatic, antiscorbutic, antiseptic, antitussive, carminative, expectorant, stomachic. With more people becoming nutrition-conscious, there has been an increase in the demand for the use of citrus fruits and their by-products as traditional medicines for conventional healthcare in developing countries.

The global food industry annually generates millions of tons of by-products derived from the processing and manufacturing of citrus fruits. Only a small part is used to obtain new products and the rest is considered as waste, with the consequent negative impact on the environment. The purpose of this research work is to use the products extracted from citrus fruits of orange, grapefruit, tangerine and lemon, being used in the diet of ruminants as a source of energy, supplement or alternative in the face of a shortage of forage. Making the use of these by-products in order to reduce the environmental impact of the waste generated.

AbstractHydrogen cyanide polymers – heterogeneous solids ranging in color from yellow to orange to brown to black – may be among the organic macromolecules most readily formed within the Solar System. The non-volatile black crust of comet Halley, for example, as well as the extensive orangebrown streaks in the atmosphere of Jupiter, might consist largely of such polymers synthesized from HCN formed by photolysis of methane and ammonia, the color observed depending on the concentration of HCN involved. Laboratory studies of these ubiquitous compounds point to the presence of polyamidine structures synthesized directly from hydrogen cyanide. These would be converted by water to polypeptides which can be further hydrolyzed to α-amino acids. Black polymers and multimers with conjugated ladder structures derived from HCN could also be formed and might well be the source of the many nitrogen heterocycles, adenine included, observed after pyrolysis. The dark brown color arising from the impacts of comet P/Shoemaker-Levy 9 on Jupiter might therefore be mainly caused by the presence of HCN polymers, whether originally present, deposited by the impactor or synthesized directly from HCN. Spectroscopic detection of these predicted macromolecules and their hydrolytic and pyrolytic by-products would strengthen significantly the hypothesis that cyanide polymerization is a preferred pathway for prebiotic and extraterrestrial chemistry.

We have developed a technique to prepare thin single crystal films of graphite for use as supporting films for high resolution electron microscopy. As we showed elsewhere (1), these films are completely noiseless and therefore can be used in the observation of phase objects by CTEM, such as single atoms or molecules as a means for overcoming the difficulties because of the background noise which appears with amorphous carbon supporting films, even though they are prepared so as to be less than 20Å thick. Since the graphite films are thinned by reaction with WO3 crystals under electron beam irradiation in the microscope, some small crystallites of WC or WC2 are inevitably left on the films as by-products. These particles are usually found to be over 10-20Å diameter but very fine particles are also formed on the film and these can serve as good test objects for studying the image formation of phase objects.
