The effectiveness of curing oranges and lemons at 33 degrees C for 65h followed by storage under ambient and cold-storage conditions was investigated. This treatment effectively reduced the incidence of Penicillium digitatum (Pers) Sacc and P italicum Wehmer decay on inoculated and naturally infected oranges and lemons stored at 20 degrees C for 7 days. However, it failed to control green and b...

Seasonal changes in °Brix and °Brix/% acid ratio of Florida early season oranges and California 'Washington Navel' oranges were fitted by linear models. The constant term varied with different climatic conditions. The rate of Florida Agricultural Experiment Station Journal Series No. N-00240. Froc. Fla. State Hort. Soc. 103: 1990. change was 0.0256 °Brix/day and 0.0735 ratio/day for Florida ear...

This study investigates how consumers value carbon dioxide (CO2) emissions of food by conducting a choice experiment before an ecolabel is attached on some foods in Japan. Participants are asked to buy some Satsuma mandarin oranges based on price and CO2 emissions and take them home. The following results are obtained: (i) the willingness-to-pay (WTP) estimate for the reduction of 1 g CO2 emiss...

Oranges are suspected of inducing adverse skin reactions in patients with atopic eczema. We studied 21 adult patients with atopic eczema and a history of adverse reactions to oranges and 10 patients without. A dietary history, skin tests, serum IgE and oral provocation tests with oranges were obtained. Severity of eczema was monitored by SCORAD, and serum tryptase, eosinophil cationic protein a...

An experimental polyethylene–candelilla-wax coating formulation was evaluated in comparison to a high-gloss, shellac and wood resin citrus coating for storage of ‘Valencia’ oranges at 15–25°C. Oranges with the wax coating had relatively high flavor scores (8.9–10.4) even after 9–16 days storage at 15–25°C. By contrast, the high-gloss coating, shown to be typical of such citrus coatings, resulte...

Among Citrus species, the sweet orange (Citrus sinensis (L.) Osbeck) is most important in terms of production volumes and cultivated areas. Oranges are particularly appreciated for organoleptic characteristics high nutraceutical value fruits (thanks especially to their content antioxidants). Recent advances citrus genetic genomic resources, such as release reference genomes several cultivars, h...

Secara umum proses menentukan jeruk manis layak (bagus) dan tidak (busuk) masih banyak menggunakan cara manual. Cara manual dilakukan berdasarkan pengamatan visual secara langsung pada buah yang akan diamati. Pengamatan dengan ini memiliki beberapa kelemahan yaitu adanya keterbatasan manusia, di pengaruhi oleh kondisi psikis pengamatannya serta memakan waktu lama terutama bagi perkebunan besar....
