“…[20][21][22][23][24][25] On the other hand, a major experimental issue in DL spectroscopy is represented by the detection of ultra-weak light signals, specially when they come from reduced sample quantities. This can be the case for DL photo-induced on a single seed, requiring higher detection sensitivity with respect to most of present-day equipment.…”

Time‐resolved spectral measurements of delayed luminescence from a single soybean seed: effects of thermal damage and correlation with germination performance

et al. 2009

Delayed luminescence from a single dry soybean seed was investigated in both spectral and time domains, under different excitation wavelengths. Emission spectra were collected, under 337 nm laser excitation, from native and artificially deteriorated seeds and the time-dependence of different spectral components was analyzed in detail. The single seed viability was evaluated through observation of germination properties after imbibition and compared with different parameters related to the luminescence kinetics. The significant correlation found between single seed delayed luminescence parameters and germination capability strongly validates the connection of this phenomenon with the functional state of the system and suggests the development of a non-invasive technique for seed quality determination.

“…Arvanitoyannis et al (2009) compiled all the research in vegetable and fruit irradiation and reported that it could prolong shelf-life, had no effect on physical and organoleptic properties and was a cheap alternative to other conventional conservation methods. Regarding chestnuts, gamma radiation has been applied on them, mainly in Asian varieties (Chung et al, 2004;Imamura et al, 2004;Iwata et al, 1959;Guo-Xin et al, 1980;Kwon et al, 2004) and recently in European varieties (Antonio et al, 2011a, b, c;Barreira et al, 2012;Calado et al, 2011;Fernandes et al, 2011a, b;Mangiacotti et al, 2009) (Table 1). It has been already approved as a commercial technique in South Korea, for sprouting or rooting inhibition (0.25 kGy) (Chung et al, 2004) and for quarantine disinfestations (0.50 kGy) .…”

“…Although chestnuts are legally irradiated in Korea (Chung et al, 2004), the public still has reservations in consuming irradiated chestnuts due to misconceptions about the alterations that gamma rays induce in colour and texture of these fruits. studied the comparative colour alteration in the internal and external flesh of chestnuts irradiated with doses of 0.25, 0.5, 1 and 10 kGy and fumigated (methyl bromide).…”

Gamma radiation has been used as a post-harvest food preservation process for many years.Chestnuts are a seasonal product consumed fresh or processed, and gamma irradiation emerged recently as a possible alternative technology for their post-harvest processing, to fulfil the requirements of international phytosanitary trade laws. After harvest and storage, several problems may occur, such as the presence of infestations and development of microorganisms, namely rotting and fungi. These diminish the quality and safety of the product, decreasing the yield along the production chain. In fruits, gamma irradiation treatment is for two main purposes: conservation (ripening delay) and insect disinfestation (phytosanitary treatment). In this review, the application of gamma irradiation to chestnuts is discussed, including production data, the irradiated species and the effects on biological (sprouting, rotting, respiration rate, insects, worms and fungi), physico-chemical (colour, texture, drying rate), nutritional (energetic value, proteins, sugars and fatty acids) and antioxidant (tocopherols, ascorbic acid, phenolics, flavonoids and antioxidant activity) parameters. These changes are the basis for detecting if the food product has been irradiated or not. The validation of standards used for detection of food irradiation, as applied to chestnuts, is also discussed.

Electron spin resonance (ESR) spectroscopy is able to directly measure the chemical species with unpaired electrons and has been widely used in a number of research fields. This review focused on its application in nutraceutical and food research. Current status of ESR in free radical scavenging capacity estimation, food oxidative stability evaluation, Cu(2+) chelating capacity determination were summarized. Also discussed was the potential of ESR spin-label oximetry technique in examination of lipid peroxidation and oxygen diffusion-concentration products in liposomes, oxygen transport and depletion, and membrane structure and dynamic properties. In addition, ESR application in identifying and estimating irradiated foods including meat, fruits, vegetables, spices, cereal grains, and oil seeds was reviewed. Finally, the potential use of ESR technique in investigating microstructure change, phase transition and viscosity related properties during food formulation, processing, and storage was briefly mentioned, along with its potential in determination of radio-stability of food components. This review may provide some fundamental knowledge of ESR and its application in nutraceutical and food research.
