    Industrial use of pepper (Capsicum annum L.) derived products : technological benefits and biological advantages
    (Elsevier, 2018-09-10) Baenas, Nieves; Belovic, Miona M.; Ilic, Nebojsa M.; Moreno, Diego A.; García-Vigueraº, Cristina; Tecnología de Alimentos, Nutrición y Bromatología
    In pursuit of new bioactive compounds and natural ingredients for agro-food, cosmetic and pharma industrial uses, as replacements for synthetic compounds and also for the valorisation of crop plant’s by-products, the recovery of pepper (Capsicum annum, L.) bioactive compounds represent an interesting strategy to develop new products for the industry. Besides, being used as a condiment, providing characteristic of pungency, colour and flavour, the new pepper-derived ingredients may be used in preservation and extension of lifespan of industrial products, as well as additives or technological ingredients with antioxidant and antimicrobial activities. Moreover, the applicability of the new products in pharmaceutical formulas for treating certain inflammatory and pain-related conditions is also a possibility, since pepper fruits mainly contain capsaicinoids, carotenoids, phenolic compounds, vitamin C and A, and minerals, such as iron and calcium, with health-promoting potential. Further studies on appropriate extraction protocols, stability, safety and bioactivity are key to provide with novel and promising pepper ingredients for foods, cosmetics, and pharmaceutical applications.

    Scanning electron microscopy of capsaicin-pretreated trachea in the rat during postnatal developrnent
    (Murcia : F. Hernández, 1995) Yu, S. M.; Lin, K. H.
    The morphological changes of the tracheal surface were studied in neonatally capsaicin-pretreated rats by scanning electron microscopy. One week after neonatal capsaicin treatment, a sparse number of ciliated cells were dispersed among the microvilli-covered goblet cells similar to those of the sham-operated rats. Potential ciliated cells (progenitor cells) possessed a few long cilia and many short cilia. The ciliated cells possessed cilia with a smooth surface and a blunt end similar to that of the sham-operated rats. Two weeks after neonatal capsaicin treatment, numerous ciliated cells frequently in clusters were located among large patches of microvilli-covered goblet cells similar to those of sham-operated rats. Furthermore, the blunt ends of cilia and microvilli contained short star-shaped protrusions extending into the lumen of the trachea. One month after neonatal capsaicin treatment, the star-shaped protrusions became longer, and more irregular than those of sham-operated rats. The short cilia of the potential ciliated cells (progenitor cells) also became blunt and irregular in shape. The star-shaped protrusions of the microvilli of the goblet cells became larger and thicker than those observed at two weeks following capsaicinpretreatment. Two months after neonatal capsaicin treatment, the tracheal surface was lined with a much greater population of the ciliated cells than that at one month. A striking characteristic at this age was that globular mucin-containing secretory products were trapped within the cilia of the ciliated cells. The results of this study suggest that mucus secretion is probably blocked by the capsaicin-pretreatment. Furthermore, the star-shaped protrusions of cilia and microvilli may indicate that the mucociliary clearance mechanism is interfered with by the capsaicin-pretreatment.
