“…Para o estado de São Paulo, a tradicional Mexerica do Rio (Rio IAC 194) tem seus frutos apropriados para colheita em campo. Esta constatação pode ser explicada pelo fato de as folhas destacadas apresentarem alterações fisiológicas que podem refletir no seu nível de resistência, tornando-as mais suscetíveis à A. alternata e outros microrganismos, uma vez que, ao ser retirada da planta, a folha perde seu poder de resposta à infecção por patógenos (Azevedo et al, 2010;Baudoin e Eckert, 1985;Chutia et al, 2009).…”

A produção de tangerinas alcança expressão econômica em alguns estados brasileiros, principalmente em São Paulo, Paraná, Rio Grande do Sul e Minas Gerais. Nos últimos anos, um interesse crescente pelas mexericas tem sido observado no estado de São Paulo, possivelmente pela inviabilidade econômica de manterem-se pomares das principais variedades comerciais para frutos de mesa, tangerina Ponkan e tangor Murcott, devido à alta suscetibilidade à mancha marrom de alternária (MMA). O objetivo deste trabalho foi caracterizar 33 acessos de mexericas do Banco Ativo de Germoplasma de Citros do Instituto Agronômico de Campinas (BAG Citros IAC), visando selecionar variedades com boas características físico-químicas como massa, altura e largura de frutos, cor da casca, rendimento de suco, acidez, sólidos solúveis e Ratio e resistência à MMA para que possam ser comercializadas em outros períodos do ano, em comparação com a variedade mexerica Rio IAC 194, padrão desse grupo, cuja maturação é de meia-estação. Os resultados demonstraram que cerca de 85% dos acessos de mexerica avaliados em campo e in vitro apresentaram resistência à MMA. Selecionaram-se cinco acessos precoces e 11 mais tardios que a Rio IAC 194 como boas alternativas para a ampliação do período de safra de mexericas no estado de São Paulo.

In recent years a growing interest in these mandarins has been observed in São Paulo, possibly due to the economic viability of maintaining the orchards of the main commercial varieties, Ponkan mandarin and Murcott tangor, due to high susceptibility to alternaria brown spot (ABS). The objective of this study was to characterize 33 accessions of willowleaf mandarins to 'Banco Ativo de Germoplasma de Citros' of the Instituto Agronômico de Campinas ('BAG Citrus IAC'), to select varieties with good horticultural characteristics as mass, height and width of fruit, skin color, juice content, acidity, soluble solids and Ratio, and tolerance to ABS and that can be marketed in other periods of the year in comparison with the Rio IAC 194 mandarin, standard variety -which ripening is half station. The results showed that to about 85% of the mandarin accessions evaluated in the field and in vitro were resistant to ABS. Was selected five hits early and later eleven more than Rio IAC 194, which can be good alternatives for the extension of the period of harvest of mandarins in the State of Sao Paulo.

“…It is one of the major commercially grown fruit crops of the world (Pal et al 2013), distributed throughout the tropical and temperate regions (Chutia et al 2009). The fruit is precious as it is rich in various nutrients such as vitamins and antioxidant compounds (Rivas et al 2007).…”

“…It is cultivated in more than 135 countries with about 102.64 million tones of production worldwide (Sajid et al 2010). In India, more than 52 varieties of citrus are found in the North-Eastern hilly states up to an altitude of 1,200 m. Some common species noticed are; C. indica, C. ichangensis, C. macroptera, C. latipes, C. aurantium, C. megaloxycarpa, C. jambhiri and C. reticulata (Chutia et al 2009). Among them, mandarin (C. reticulata) occupies nearly 40 % of the total area under citrus cultivation with a share of about 41 % of all citrus fruits produced in India.…”

“…Among all of the evaluated attributes, color, citrus aroma, fresh flavor and viscosity were significantly different ( Table 7). The The addition of the essential oil resulted in the lighter color of the fresh orange juice, due to the bright yellow color of the sweet orange essential oil; enhanced the citrus aroma and fresh flavor of the orange juice, due to the large percentages of monoterpenes (C l0 /H l6 ) and smaller amounts of sesquiterpenes (C l5 /H 24 ) that carry the oxygenated compounds comprising alcohols, aldehydes, ketones, acids and esters which are responsible for the characteristic odor and flavor profiles [26,27]; and affected the viscosity from slightly watery to watery due to the high viscosity of the essential oil itself.…”

Nowadays, consumers are demanding for minimally processed, additive-free, high quality, fresh-like and microbiologically safe foods. However, as food deterioration is the constant threat along the entire food chain, food preservation remains as necessary today as in the past. In this paper, several citrus essential oils, including sweet orange, lemon and lime essential oil applied directly in fresh orange juice as a natural preservative, were analyzed for their antimicrobial activity. The antimicrobial activity of each citrus essential oil was assessed against Saccharomyces cerevisiae, Lactobacillus plantarum and Aspergillus niger using broth macrodilution. Among all citrus essential oils tested, sweet orange essential oil with 0.10% concentration showed significant antimicrobial activity against microorganisms tested. Hence, it was chosen to be applied in the fresh orange juice. Then, shelf life analysis was conducted during 7 d of storage at 5 °C and during 2 d of storage at 25 °C using selected concentration of the selected citrus essential oil in the fresh orange juice. Based on the results obtained, the addition of sweet orange essential oil with 0.10% concentration was not able to prolong the shelf life of the fresh orange juice according to the Indonesian National Standard (SNI). However, the formulation of fresh orange juice itself was able to improve its shelf life when compared to the shelf life of the commercial orange juice.
