Disinfestation of red flour beetle (Tribolium castaneum) present in almonds (Prunus dulcis) using microwave heating and evaluation of quality and shelf life of almonds

Impact of radiofrequency disinfestation on Tribolium castaneum (Herbst) in wheat flour and its influence on the functional characteristics of wheat flour

“…Pesticides are often used to avoid losses associated with infestation throughout the storage of wheat flour, contributing to the issue of pesticide tolerance in insects as well as residues in food products (Zhao et al, 2020). Therefore, an alternative method for disinfecting the insects in wheat flour needs to be explored.Novel electromagnetic wave techniques are enticing the researchers as they leave no toxic substances in the food product and for not inducing insect resistance (Patil et al, 2020). In recent history, radiofrequency (RF) disinfestation is an emerging technology to prevent food commodities from infestation during storage.Radiofrequency waves range from 1 to 300 MHz, whereas 13.56, 27.12, and 40.68 MHz are reserved for commercial, technological, and medical purposes, with a view to prevent possible interference with other spectrum users (Ozturk et al, 2017).…”

“…Experimental studies on stored rapeseeds (Yu et al, 2016) revealed that 100% mortality of Tribolium castaneum (Herbst) could be achieved at 80℃ for adult and 60℃ for larva phases at different moisture content level, without significant degradation in seed quality with appropriate RF heating parameters. The red flour beetle, T. castaneum is the most strongly connected insect with post-harvest infestation (Patil et al, 2020), worldwide and the major insect that presents in wheat flour (Wong & Lee, 2011). This study explored the impact of RF heating in disinfestation of T. castaneum and also to evaluate the quality and functional characteristics of wheat flour by optimizing the RF treatment parameters (exposure time and electrode current) and also to find the effect of RF heating in sensory parameters of chapati as the end product of RF-treated wheat flour.…”

Mikrodalga Radyasyonun Un biti, Tribolium castaneum (Herbst, 1797) (Coleoptera: Tenebrionidae)’a Etkisi

“…Yakın zamanda yapılan bir çalışmada farklı sürelerde (30-90 sn) uygulanan farklı radyasyon seviyelerinin (120-600 w) T. castaneum üzerindeki letal etkileri belirlenmiştir. Elde edilen verilere göre 60 ve 90 sn süreyle uygulanan 480 ve 600 w radyasyon değerlerinin uygulamadaki bütün bireyleri öldürdüğü belirlenmiştir [36]. Bu çalışma sonucunda elde edilen verilerin tamamı incelendiğinde literatürde olduğu gibi fiziksel bir mücadele yöntemi olan mikrodalga radyasyonunun T. castaneum ergin bireyleri üzerinde öldürücü etki gösterdiği saptanmıştır.…”

“…Kullanılan bu yöntemde uygulanan ışın zararlıya iyi bir şekilde nüfuz etmekte ve hem ürünün içindeki hem de dışındaki böcekleri öldürebilmektedir [25]. Bu çalışmanın da ana materyali olan Tribolium castaneum (Herbst) ve farklı depo zararlıları üzerinde mikrodalga radyasyonun etkileri ile ilgili bazı çalışmalar yürütülmüş ve olumlu sonuçlar elde edilmiştir [26][27][28][29][30][31][32][33][34][35][36].…”
