“…It has been used in conjunction with refrigeration to extend the storage life of certain fresh food products (Smith, 1963). Long-term CA treatment for apple storage retains fruit quality and reduces decay (Sitton & Patterson, 1992). Generally, oxygen is decreased from the normal 21% in air to 1-3%, and carbon dioxide is increased from 0.04% to 1.5-5%, depending on the commodity.…”

“…Para reduzir os prejuízos, métodos físicos, químicos e biológicos vêm sendo empregados, visando o controle deste grupo de doenças (Eckert & Ogawa, 1985;Wilson & Wisniewski, 1994;Sitton & Patterson, 1992). Os métodos físico e biológico se constituem em alternativas viáveis e desejáveis em relação ao químico tradicional, principalmente em função de não deixarem resíduos tóxicos nos frutos tratados.…”

RESUMO: Extratos aquosos foram obtidos a partir de bulbilhos de alho, folhas de hortelã e mamona e frutos de pimenta. Após a incorporação destes extratos em BDA, obtendo-se concentrações de 100, 200, 500, 1000, 5000 e 10000 ppm, foi avaliado o crescimento e a produção de conídios de um isolado de Colletotrichum gloeosporioides, agente de podridão em frutos de mamoeiro. Os resultados demonstraram o efeito inibitório dos diferentes extratos a partir da concentração de 200 ppm. O extrato de alho inibiu o crescimento micelial, em porcentagens variáveis de 5,3 a 67,6%, porém não atuou de modo expressivo sobre a produção de conídios. Em contraposição, os extratos de hortelã, mamona e pimenta promoveram inibição menos acentuada do crescimento de micélio, porém reduziram drasticamente a produção de conídios em níveis variáveis de 41 a 84%, de acordo com as concentrações crescentes dos mesmos. As propriedades fungitóxicas detectadas nos extratos utilizados no ensaio evidenciaram o uso potencial dos mesmos como alternativa aos métodos físicos e químicos convencionalmente usados para o controle da doença.

Micelial growth and the conidium production were evaluated in these media. All extracts exhibited inhibitory effect at the concentration of 200 mg/g and above. Garlic extracts inhibited micelial growth in the range of 5.3 to 67.6%, it had, however no effect on sporulation. Peppermint, castor bean and pepper extracts promoted micelium inhibition and reduced the conidium production in the range of 41 to 84%, according to the extract concentrations. It was demonstrated that the different extracts have antifungal activities and that they have a potential use as an alternative control in relation to physical or chemical methods.

“…After four days under ambient conditions, decay was not different between treatments. The effects of the CA on decay reduction may be attributed to the low levels of O 2 combined with high levels of CO 2, which presented a fungi static effect, inhibiting spore germination and fungal growth during the storage period (Sitton and Patterson, 1997;Wszelaki and Mitcham, 2000;Vieira et al, 2006).…”

The optimum condition for storage of 'Laetitia' plums (Prunus salicina) under controlled atmosphere (CA) is not currently known. This study was aimed at assessing the effects of controlled atmospheric (CA) conditions on the postharvest quality preservation of 'Laetitia' plums. Besides regular atmosphere (RA; 21kPa O 2 + 0.03 kPa CO 2 ) as condition/treatment control, the following CA conditions (kPa O 2 + kPa CO 2 ) were assessed: 1+3; 1+5; 2+5; 2+10; and 11+10. In all cases, the fruit were stored for 60 days at 0.5°C±0.1°C and 96±2% of relative humidity (RH). Upon removal from the cold storage chamber and after four days in ambient conditions (20±2°C/60±5% RH), the fruit were assessed in terms of: respiration and ethylene production rates; flesh firmness; texture; titrable acidity; red color index and hue angle (h o ) of the skin; incidence of fruit cracking and internal breakdown (flesh browning). The fruit stored under the different CA conditions presented lower respiration and ethylene production rates, higher values of flesh firmness, texture and titrable acidity, lower development of skin red color, and lower incidence of skin cracking compared to the fruit under RA. CA conditions of 2+5, 1+5, and 1+3 resulted in a more substantial delay of ripening. CA conditions of 2+5 and 1+3 resulted in lower incidence of internal breakdown.
