摘要：

The objective of this study was to evaluate the post-harvest conservation of guavira (Campomanesia adamantium Camb.) in different coatings and temperatures. The fruit received the following treatments: immersion in 1) 1% carboxy methylcellulose (w/v) (CMC) 2) 3% pectin, 3) pectin + 3% calcium chloride (w/v) and 4) no treatment (ST) all packaged in low density polyethylene (LDPE) and stored for 0, 7, 14 and 21 days in B.O.D. at temperatures of 5, 10 and 15 degrees C. The lowest weight loss and titratable acidity were observed at 5 degrees C and the coated with pectin + calcium. The pH did not vary between the coatings and kept higher than 5 degrees C. The vitamin C content was higher under the influence of the coating of pectin + calcium with initial values similar to the 5 and 10 degrees C. It was concluded that the guaviras can be stored for up to 21 days at 5 degrees C, coated with pectin + 3% calcium.
