Edible insects are widely consumed in different parts of the world and can serve as an alternative nutritional source to conventional foods. Nonetheless, little attention has been given to their quality and shelf life in different packages when exposed to different storage environments. In this study, the effect of storage temperature, duration and type of packaging on the storage stability of the adult house cricket meal was examined. The samples were boiled, solar dried, milled and packaged into polypropylene (PP), plastic (PL) and polyethylene (PL) packages. The samples were then stored for six months in refrigerated and ambient conditions where by changes in physical and biochemical attributes were monitored. Iodine values significantly decreased in all the packages while peroxide, p-anisidine and saponification values significantly increased. SFA, MUFA and PUFA contents reduced during storage although a higher tendency for MUFA and PUFA values was observed in the refrigerated samples. Total viable count (TVC) and yeast and molds counts significantly increased in storage. Three types of fungi; Aspergillus spp., Alternaria spp. and Penicillium spp. were isolated in all the packages. Overall color change steadily decreased with increase in storage time. Deterioration was higher in samples stored in ambient conditions than in refrigeration. The degree of deterioration in the two storage environments among the different packages was in the order; PP>PE>PL. Although the PL package outperformed the other packages it is recommended to carry out sensory analysis and avoid post-processing contamination that can adversely affect the product quality and safety during storage.

Abstract: The evaluation of seed deterioration is very important to control the quality of the seeds stored. This study aimed to investigate the potential of fast ethanol assay for seed quality assessment of maize stored under different conditions. The first experiment was to determine the incubating temperature, incubating time, and amount of seed used in the assay. The results showed that the best protocol for the detection of headspace ethanol was incubation of 3 g of maize seed with 20% moisture content (wet basis) in a 20 mL gas chromatography vial at 70 °C for 1.5 h. The assay induced approximately 200-700 µg.L-1 of headspace ethanol, which was sufficient to identify seeds with different vigour levels. In the second experiment, the optimal conditions were used for quality assessment in aged maize seed stored for 12 months under different storage conditions. The increase in the ethanol production of stored maize seed under the controlled conditions (15 °C and 20% RH in the hermetic seal) was lower than under ambient conditions. The ethanol production levels of maize seed samples at the start of storage was significantly lesser than at six months storage (p < 0.05). The test limitations in deteriorated seed with different cultivars and ages will be discussed.

The study was carried out to minimize the postharvest loses and extend shelf life of mango fruitby maintaining physico-chemical properties. The variety selected for the study was “Amrapali”. Freshly harvested mango was treated with different concentrations (20% and 40%) of neem leaf and banana pulp extract alone or in combination. Untreated mango was considered as control. All treated and untreated mango was kept into paper cartons at room condition. The treated fruits showed significant differences in case of total soluble solids content, titratable acidity, vitamin C, disease incidence, disease severity and shelf life in comparison to control fruits. Among the treatments, T2 (neem leaf extract at 20%) and T5 (neem leaf extract 40% + banana pulp extract 40%) treatments showed longer shelf life (9.92 and 10.25 days, respectively), slower changes in color (score 2.77 and 2.93, respectively) and firmness (score 2.67 and 2.77, respectively); less disease severity (score 2.93 and 3.57, respectively), disease incidence (46.67% and 60.00%) and lower loss in weight (38.04% and 35.17%, respectively) at 9 DAT (Days after treatment). On the other hand, total soluble solid was highest in T3 (neem leaf extract 40%) treated fruitswith18.73% more Brix at 13 DAT in comparison to control and other treatments. The effectiveness of the treatment T5 (neem leaf extract 40% + banana pulp extract 40%) was meaningful which could be recommended for maintenance of postharvest quality of mango stored in ambient conditions.

AbstractWe report a new integration approach to produce arrays of ZnO microcrystals for optoelectronic and photovoltaic applications. Demonstrated applications are n-ZnO/p-GaN heterojunction LEDs and photovoltaic cells. The integration process uses an oxygen plasma treatment in combination with a photoresist pattern on Magnesium doped GaN substrates to define a narrow sub-100nm width nucleation region. ZnO is synthesized in the defined areas by a hydrothermal technique using zinc acetate and hexamethylenetetramine precursors. Nucleation is followed by lateral epitaxial overgrowth producing single crystal disks of ZnO. The process provides control over the dimension and location of the ZnO crystals. The quality of the patterned ZnO is high; the commonly observed defect related emission in the electroluminescence spectra is suppressed and a single near-band-edge UV peak is observed. Transfer printing of the ZnO microcrystals onto a flexible substrate is also demonstrated in the context of transparent flexible electronics.
