This study was carried out to determine the shelf-life of cricket powder and investigate the changes in its quality during storage. To determine the shelf-life, cricket powder was stored at temperatures of 25, 35, and 40℃ for 6 months. The changes in quality parameters of the cricket powder, such as moisture content, color, acid value, volatile base nitrogen (VBN), fatty acid, growth of microorganisms, and sensory appeal were investigated. The moisture content of the cricket powder increased during storage but did not show any significant difference at 6 months of storage. L value was increased at 25℃ storage but decreased at 35 and 40℃. However, there were no significant different in a and b values. The acid value decreased more rapidly at higher temperatures, while the VBN content was not changed. The major composition of fatty acids of cricket powder were palmitic acid, oleic acid, and linoleic acid. Their content was not changed at various the storage temperatures. No aerobic and coliform bacteria grew in the powder during the whole storage period. Cricket powder stored at 25℃ and 35℃ showed similar scores in sensory evaluation, but it storaged at 40℃ showed the significant difference (p<0.05). Moisture content, acid value, oleic acid, and flavor were selected as the criteria for shelf-life establishment of cricket powder. Based on these parameters, especially the moisture content, the shelf life of cricket powder was likely to be 18 months when stored at 25℃.

Protaetia brevitarsis seulensis (Kolbe) is widely used in Korea, as a protein-rich, alternate, functional food with pharmacological benefits. In addition to anti-oxidant properties, the larvae of P. b. seulensis also show positive effects against hepatic disorder and diabetes; therefore, P. b. seulensis larvae are being reared on a large scale in Korea. We evaluated reared larvae of P. b. seulensis from Gyeong-gi in Korea. Using 16SrRNA PCR, electro-microscopy, and bioassay techniques, we found that the larvae harbored Spo-1, a bacterium identified as the insect pathogen Serratia marcescens. Therefore, we highlight the use of this insect as an alternate food and the need for its sanitary rearing conditions, as contamination may affect public health. IntroductionThe white-spotted flower chafer, Protaetia brevitarsis seulensis, is an insect that belongs to Coleoptera species (Coleoptera: Scarabaeidae). Its life cycle includes the embryo, larva, pupa, and imago stages, of which the larval stage is the longest, where the insect feeds and stores energy for the rest of its life cycle. In Asian countries, P. brevitarsis seulensis larvae are generally known to be pharmacologically effective and used as medicine (Suh et al., 2010). Several reports suggest that P. brevitarsis extract in Lewis' methanol has antioxidant (Suh et al., 2010), anti-hepatofibrosis, and anti-diabetic properties (Miyanoshita et al., 1996). In addition, scientific reports highlight that, based on the composition of P. brevitarsis seulensis larvae, they can be used as a functional health food. Thus, it is essential to verify that the rearing conditions for P. brevitarsis seulensis larvae are sanitary and safe for consumption as food. On the other hand, Serratia marcescens is a bacterial pathogen, found in soil (Grimont and Grimont, 2006), water (Ajithkumar, 2003;Grimont and Grimont, 2006), and plant material (Grimont and Grimont, 2006). It is also known by alternate names such as Bacillus sphingidis (White, G.F., 1923) and Bacillus asepticus (Burnside, 1928) when it does not show its characteristic red pigment but rather grows as white colonies. S. marcescens and Serratia sp. generally are known to be fatal pathogens of several insect species (Orthoptera, Coleoptera, Hymenoptera, Lepidoptera, and Diptera) once they enter the hemocoel (Tanada et al., 1993

“…According to the recent safety evaluations of Pbl's toxicity and content of harmful substances by Hwang et al (2001Hwang et al ( , 2007, Chung et al (2013), Jo et al (2008), Lee et al (2001b), Park et al (2012), and Noh et al (2015), no risk factors have yet been found in Pbl. Moreover, since the pretreatment conditions needed to utilize Pbl as a food ingredient were defined by Kwon et al (2013), the Ministry of Food and Drug Safety (MFDS) approved its use as food from October 2014 onward. Pbl can now be manufactured and marketed as food in the Republic of Korea (Yoon et al 2016).…”

To develop a system for the mass production of Protaetia brevitarsis larvae (Pbl), this study analyzed the oviposition characteristics of third instar Pbl through successive rearing and cold treatments. In the first generation, females laid 50 eggs each on average, and spawned higher numbers of eggs for the first 5 days but then fewer after this. However, all of the 2nd‐generation females that were produced through the successive rearing of eggs from the 1st generation did not spawn. When test insects (TI) were raised at 32°C, their mean ± SE pupal period and emergence rate were 28.4 ± 1.9 days and 87%, respectively. However, most individuals raised in cold treatments (5°C and − 5°C) without a pre‐cooling period did not survive. Individuals exposed to a pre‐cooling period, however, had a 7–10 days longer pupal period than those raised at 32°C, and their emergence rate (90%) was slightly higher. Different cold treatment temperatures (0°C, 3°C, or 5°C) and periods (30 or 60 days) were tested in further experiments. The experimental group kept for 30 days at 0°C and 3°C had the shortest pupal period of all, and emergence rates exceeded 90% in most groups. With respect to the number of eggs spawned by the second generation females after cold treatments, the experimental groups held in cold treatments at 5°C for 30 and 60 days were found to spawn the most eggs. Consequently, the experimental group kept at 5°C for 30 days was the most effective set of conditions tested during the entire breeding period.
