Este trabalho apresenta elementos que visam dar embasamento teórico para a aquisição de itens hortifrutigranjeiros, uma vez que nessa atividade as compras dos lotes de mercadorias acontecem geralmente através de deduções ou pela média de venda dos produtos. O artigo apresenta um estudo de caso, envolvendo pesquisa observatória sobre o estado de conservação de hortifrutigranjeiros, elaborada por meio de relatos diários, de acordo com a disponibilidade de cada mercadoria. Foram analisados os seguintes itens: alface (Lactuca sativa); batata cv. monalisa (Solanum tuberosum); maçã cv. fuji (Malus domestica); maçã cv. gala (Malus domestica); mamão cv. formosa (Carica papaya); mamão cv. papaia (Carica papaya); manga (Mangifera indica); morango (Fragaria × ananassa), repolho verde (Brassica oleracea L. var. capitata) e tomate longa vida (Solanum lycopersicum), desde a sua chegada até o seu escoamento na prateleira ou por descarte. Os produtos que apresentaram os maiores percentuais de perdas foram: maçã cv. fuji, repolho e manga. Os itens com menores quebras foram: tomate longa vida, batata cv. monalisa e maçã cv. gala. O volume adquirido de cada item interferiu diretamente no resultado.

La antracnosis es una enfermedad causada por varias especies del género Colletotrichum en diferentes hospederos. C. acutatum y C. gloeosporioides son especies morfológicamente similares, que pueden causar síntomas similares en el mismo hospedero. Se colectaron 220 aislamientos de Colletotrichum de muestras con síntomas típicos de antracnosis en helecho hoja de cuero (Rumohra adiantiformis), limón criollo (Citrus aurantifolia), carambola (Averrhoa carambola), papaya (Carica papaya) y mango (Mangifera indica) en Costa Rica y Florida, Estados Unidos. Los aislamientos se caracterizaron por morfología de colonia, sensibilidad al benomil, y PCR con los iniciadores específicos para C. acutatum y C. gloeosporioides CaInt2 y Cg/fInt1, respectivamente; también se analizó la morfología de las colonias de ambas especies. De los 85 aislamientos obtenidos de mango, todos los aislamientos de Florida fueron identificados como C. acutatum, mientras que todos los aislamientos de Costa Rica fueron C. gloeosporioides. De los 60 aislamientos de carambola, 3 provenientes de Costa Rica fueron C. acutatum (primer informe) y el resto fueron C. gloeosporioides. Todos los aislamientos de helecho hoja de cuero (25 aislamientos) y de limón criollo (25 aislamientos) se identificaron como C. acutatum. Los demás aislamientos de carambola y mango así como todos los aislamientos de papaya, se identificaron como C. gloeosporioides. No se encontró diferenciación de síntomas entre ambas especies sobre los hospederos donde se encontraron.

A antracnose, causada por Colletotrichum spp., pode ocasionar grandes perdas a nível de campo e em pós-colheita sobre diversas culturas e seus produtos. O presente trabalho teve por objetivos testar a patogenicidade cruzada de isolados de C. gloeosporioides do caju (Anacardium occidentale) (CAJ), manga (Mangifera indica) (MG), mamão (Carica papaya) (MM), maracujá (Passiflora edulis) (MR) e C. musae da banana (Musa spp.) (BAJ); avaliar a produção de enzimas extracelulares (amilolítica, celulolítica, lipolítica e proteolítica) produzidas pelos isolados em substratos sólidos específicos; e detectar padrões eletroforéticos de proteínas totais e isoenzimas (alfa-esterase, beta-esterase, fosfatase ácida e leucina aminopeptidase). Na análise da patogenicidade cruzada, todos os isolados de Colletotrichum spp. induziram lesões necróticas, deprimidas sobre os frutos, exceto em maracujá que foi suscetível tão somente ao isolado MR. Quanto à produção de enzimas extracelulares hidrolíticas, os isolados de C. gloeosporioides produziram amilase, lipase, protease e celulase, sendo que esta última enzima não foi detectada em C. musae. Com relação à análise eletroforética de proteínas totais e isoenzimas, os isolados apresentaram variações no número e posição das bandas no gel de poliacrilamida em todos os sistemas, com exceção de leucina aminopeptidase, onde bandas monomórficas foram formadas, sem variação na intensidade e pouca variação na mobilidade relativa.

In effort to combat environmental pollution, improve animal production and avoid drug residue, producers have resorted to the use of phytobiotics to inhibit ammonia producing microbes in the gut. Freshly harvested Azadirachta indica, Carica papaya, Saccharum officinarum, Chromolaena odorata, Eucalyptus camadulensis and Mangifera indica leaves were air dried, blended and extracted using five concentrations of solvent (100% water, 70% water + 30% methanol, 50% water + 50% methanol, 30% water + 70% methanol and 100% methanol). The antibacterial activities of the extracts and antibiotics (doxycycline) as control, were tested according to standard procedures against both gram positive (Bacillus subtilis, Staphylococcus aureus) and gram negative (Escherichia coli, Vibrio cholerae) ammonia producing bacteria. In most cases, it was observed that the inhibitory effect of methanolic extracts of Azadirachta indica, Carica papaya, Saccharum officinarum, Chromolaena odorata, Eucalyptus camadulensis and Mangifera indica leaves were not significantly different from that of synthetic antibiotics, doxycycline, when tested against the test bacteria, Bacillus subtilis, Staphylococcus aureus and Vibrio cholera. However, leave extracts showed significantly better inhibitory effect on Escherichia coli than the antibiotic drug. It can be concluded, therefore, that the leaf extracts of Azadirachta indica, Carica papaya, Saccharum officinarum, Chromolaena odorata, Eucalyptus camadulensis and Mangifera indica can serve as alternative to synthetic drugs in animal production due to their effective actions against microbial organisms.

Administration of large oral doses of retinyl palmitate has become the most widely practised vitamin A deficiency prevention strategy in developing countries. We conducted a follow-up study among 220 Senegalese children aged 2–7 years suffering from moderate undernutrition to determine the efficacy of vitamin A treatment on their vitamin A status assessed by biochemical and cytological (impression cytology with transfer) methods. The first examination (T = 0 m[onth]) was carried out during April 1989, before the mango (Mangifera indica L,) harvest. The second examination (T = 2 m) was carried out 2 months after vitamin A treatment during June 1989 when ripe mangoes become widely available. Conjunctival cells of the eyes of the children with or without ocular inflammation were responsive to vitamin A administration (P < 0.01). There was a significant increase (P < 0.001) in mean serum retinol and β-carotene levels between T = 0 m and T = 2 m. Mean serum retinol-binding protein (RBP) and transthyretin (TTR) levels did not differ significantly (P > 0.05) at T = 0 m and T = 2 m. Despite the intake of vitamin A, 54% of the children who had abnormal cytology at T = 0 m remained abnormal at T = 2 m. This was due to inadequate levels of TTR and RBP, presumably due to the cereal diet eaten by the Senegalese population. Children with abnormal eye cytology had lower serum retinol levels than those with normal eyes at T = 0 m, and β-carotene values did not correlate with eye cytological abnormalities at T = 0 m. Children with normal cytology had higher serum retinol and also β-carotene levels than those with abnormal cytology after massive oral doses of vitamin A and consumption of mangoes at T = 2 m. Retinyl palmitate may, therefore, only lead to partial cytological improvement due to a lack of retinol-carrier proteins but dietary β-carotene may also be involved

The aim of this research was to study the evolution of carotenoid compounds, antioxidant β-ctivity, volatiles and sensory quality in two mango cultivars dried at 50, 60 and 70 °C. Total carotenoids in fresh samples were about 12 and 6 mg/100 g (dry basis) in Keitt and Osteen samples, respectively. β-carotene was the main carotenoid, representing about 50% of total carotenoids. In both cultivars, carotenoids were more susceptible to drying at 60 °C. Total phenols and metal reduction activity were higher in Osteen than in Keitt, which had higher values in radical scavenging capacity. The antioxidant activities were best preserved with drying temperatures at 50 °C in Keitt and 60 °C in Osteen fruits. Fresh Osteen mango fruits had a volatile compound content of about 37.1, while Keitt of about 5.2 mg/kg (dry basis). All the compounds with odorous impact were significantly reduced after drying. As regards organoleptic characteristics through sensory analysis, Keitt dried mangoes were quite similar to the fresh product, compared to Osteen.
