        <p>Ushbu maqolada ipak sifatini saqlab qolish uchun jonli ipak qurti pillalarini devitalizatsiya qilishning turli xil yondashuvlari ko‘rib chiqilgan. Pillalarni devitalizatsiya qilishning turli usullari tasniflanadi va muhokama qilinadi. Binobarin, ipak ishlab chiqarish yil davomida, pilla bosqichidan yangi yil mavsumigacha uzluksiz davom etishi mumkin. Bizning tadqiqotimiz jonli pillalarni devitalizatsiya qilish va ularning namligini oldindan davolash jarayoni sifatida kamaytirish muhimligini ta‘kidlaydi. Topilmalar ipak ishlab chiqarishning kerakli sifatini saqlab qolishda ushbu usullarning ahamiyatiga oydinlik kiritdi.</p>

        <p>This article examines various approaches to the devitalization of live silkworm cocoons in order to preserve the quality of silk. Different methods of devitalizing cocoons are classified and discussed. Consequently, silk production can continue without interruption throughout the year, from the cocoon stage to the new season. Our research emphasizes the importance of devitalizing live cocoons and of reducing their moisture as a pre-treatment process. The findings have clarified the significance of these methods in maintaining the required quality of silk production.</p>

        <p>В данной статье рассмотрены различные подходы к девитализации живых коконов тутового шелкопряда для сохранения качества шёлка. Классифицированы и обсуждены различные способы девитализации коконов. Благодаря этому производство шёлка может непрерывно продолжаться в течение всего года — от стадии кокона до нового сезона. Наше исследование подчёркивает важность девитализации живых коконов и снижения их влажности как процесса предварительной обработки. Полученные результаты прояснили значение этих способов в сохранении необходимого качества производства шёлка.</p>
