Extraction of chitin and chitosan from larval exuvium and whole body of edible mealworm, Tenebrio molitor

Abstract: The purpose of this study was to investigate the production of chitin and chitosan from both the exuvium and whole body of mealworm (Tenebrio molitor) larvae. Chitin from the exuvium and whole body of T. molitor larvae was chemically extracted with acid and alkali solutions to achieve demineralization (DM) and deproteinization (DP), respectively. The average DM (%) and DP (%) on a dry weight (DW) basis was 32.56 and 73.16% from larval exuvium, and 41.68 and 91.53% from whole body, respectively. To obtain chito… Show more

“…in both insect meal samples, total protein digestibility was negatively correlated with the content of aDF and chitin. however, average chitin yields in mealworm larvae were estimated at 4.92% of dry matter [16,28]. therefore, the effect of chitin in this study could not be significant due to its relative low content of the MwM diet.…”

“…Chitin can be extracted chemically or biologically via fermentation with microorganisms and enzymes, the latter method being much more environmental friendly (Rumpold et al, 2017). The first method using acid and alkali solutions yielded 4.9% chitin and 3.7% chitosan from yellow mealworm larvae (Song et al, 2018). The enzymatic method was explored with black soldier fly prepupae (Caligiani et al, 2018).…”

“…Another area of interest consists of the development of functional ingredients for food, feed, pharmaceutical, and industrial applications. Ingredients of interest such as chitin (Song et al., ), oleic acid (Purschke, Stegmann, Schreiner, & Jäger, ; Sun et al., ), proteins (Bußler, Rumpold, Jander, Rawel, & Schlüter, ; Huang et al., ; Ndiritu, Kinyuru, Kenji, & Gichuhi, ), and bioactive peptides (Montowska, Kowalczewski, Rybicka, & Fornal, ; Nongonierma & FitzGerald, ; Zielińska, Karaś, & Jakubczyk, ) have been partially or totally extracted and purified. Nonetheless, scaling up these processes to the industrial level would still be too costly (Lamsal, Wang, Pinsirodom, & Dossey, ).…”
