The effects of a dose of 2.0 kGy (Co-60) and three ranges of storage temperature (0-4°C, 9-11°C, 18-19°C) on increasing the shelf-life and some quality properties of the mushrooms were investigated. The retardation of mushroom growth and ageing by ionizing radiation was estimated by measurements of the cap diameter, stem elongation, cap opening and discoloration of cap surface. The control of fungal and bacterial diseases was also evaluated. The effect of lower doses, 0.5 and 1.0 kGy, was compared at the storage temperature of 10°C. The irradiation of mushrooms soon after harvest and storage at temperatures of 10 and 16°C allowed the retention of quality and increased the shelf-life to 8 days; at 18-19°C to 6 days.

In this paper, the effect of the packaging material and storage method on red raspberries produced at Reggio Calabria (Italy) was studied. For this purpose, the fruits were stored immediately after harvest in different conditions: in the fridge at 1 °C and in the freezer at −20 °C, using different packaging materials, two new patented films (nanoactive A) and (nanoactive B), one common packaging film (polyethylene terephthalate), and other fruits were left without any packaging material. Chemical parameters were analysed at harvest to have the initial characteristics without any conditioned storage and to distinguish the post-harvest effect on the fruits, then daily for storage in the fridge and monthly for storage in the freezer. The aims of our project were first to determine the qualitative characterization of these red raspberries, the optimization of their shelf-life during time in the fridge or freezer, using the different types of packaging materials and finally to highlight the usefulness of the new patented packaging materials. Nanoactive A film showed the best shelf-life in the fridge, and after 14 days the values, given as mg/100 g fresh weight, were: total phenolics (166.70), monomeric anthocyanin content (50.82), flavonoids (24.64), ascorbic acid (32.42), and 1, 1-diphenyl-2-picrylhydrazyl (DPPH) assay (95.93).

This work was undertaken to evaluate the effect of milling speed on the quality and shelf life of maize flour. Maize flour was prepared using low speed mini flour mill at 75 and 115 rpm and the results were compared with the flour prepared by commercial flour mill on the basis of recovery of flour, rise in temperature of flour, time taken, particle size distribution and changes in different quality parameters during storage. It was observed from the analysis that the recovery of flour was highest (95.26%) at 75 rpm speed although the time taken was more i.e. 27.27 minutes, but the rise in temperature during milling was very less (12.240C) as compared to commercial mill the temperature rose up to 31.120C. It was noted that the maize flour prepared at low speed was light yellow in color as compared to higher rpm which was dark yellow. The maize flour prepared at 75 rpm can be stored in low density polyethylene LDPE packaging material of (200 gauge) for two months without change in quality parameters. It was observed that the moisture content, protein content, fat content, alcoholic acidity and carbohydrates was significantly affected by storage time, packaging material and milling speed at P<0.05. Therefore, at low speed the storage stability as well as nutritional properties of the flour can be enhanced. The improved shelf life of flour can result in better marketability.
