Postharvest response of wild lowbush blueberry (Vaccinium angustifolium Ait. and V. myrtilloides Michx.) to mechanical damage and storage temperature was studied during 2 years. Fruit weight loss and the incidence of shriveled or split berries were major components that contributed to the loss of marketable yield resulting from mechanical damage and storage temperature. Decay of berries resulted in only 1% to 2% of the total marketable fruit loss. In general, the major quality attributes (firmness, microbial growth, hue, bloom, split, and unblemished berries) deteriorated with increasing damage levels and increasing storage temperature without significant interaction. Temperature had consistent effects in both years on moisture content, soluble solids concentration, titratable acids, weight loss, shriveled and decayed berries, Hunter L values, and anthocyanin leakage, while damage level had inconsistent or no significant effect.

English style crumpets were packaged in the atmosphere of CO2 and N2 (3 :2) and stored at 20") 22") 24" and 30°C. In all cases, package volume and headspace CO2 concentration decreased during the first week of storage. At 3O"C, the volume started to increase after 12 days due to production of CO2 and other metabolites by microorganisms. At 24'C, the volume did not start to increase until after 25 days, while at 22" and 2O'C it remained stable or gradually decreasing. Aerobic plate counts and metabolites were higher in the product stored at 30°C for 19 days than those stored at 20°C for 1 month. Product pH after 1 month at 20°C was lower (5.9) than that at 30°C for 19 days (6.5) due, essentially, to the absorption of co2.
