QUE SIGNIFIE LAC INSECT EN ANGLAIS
Lac
Le lac est la sécrétion résineuse écarlate d'un certain nombre d'espèces d'insectes, à savoir certaines espèces des genres Metatachardia, Laccifer, Tachordiella, Austrotacharidia, Afrotachardina et Tachardina de la superfamille Coccoidea, dont l'espèce la plus cultivée est Kerria lacca. Les familles mentionnées ci-dessus sont quelques-unes des 28 familles d'insectes à l'échelle et de cochenilles comprenant un grand groupe d'environ 8 000 espèces décrites d'insectes sucriers végétaux, dont quelques-uns produisent des produits naturels semblables. Des milliers de ces minuscules insectes colonisent des branches d'arbres hôtes appropriés et sécrètent le pigment résineux. Les branches revêtues des arbres hôtes sont coupées et récoltées sous forme de sticklac. Le sticklac récolté est écrasé et tamisé pour éliminer les impuretés. Le matériau tamisé est ensuite lavé à plusieurs reprises pour éliminer les parties d'insectes et d'autres matières solubles. Le produit résultant est connu sous le nom de seedlac. Le préfixe de semences se réfère à sa forme de pastille. Seedlac qui contient encore 3-5% d'impuretés est transformé en gomme laque par traitement thermique ou extraction au solvant.
