The invention relates to a silk-reeling technology by the utilization of tussah fresh cocoon live pupae. The technology includes the steps that vacuum low-temperature
permeation is performed on tussah fresh silkworm cocoons of the live pupae after
refrigeration and freshness retaining in a vacuum environment at
water temperature of 26 DEG C-40 DEG C, wherein the pH value is 6.5-8; according to vacuum low-temperature chemical cocoon reeling, water,
sodium carbonate,
sodium silicate,
sodium borate,
hydrogen peroxide and N-
coconut oil-
potassium glutamate form a reeling solution, and at temperature of 30 DEG C-46 DEG C, vacuumizing is performed for reeling in the pH value of 4-14; according to constant-temperature cocoon
blanching, the cocoons are soaked in the reeling solution at temperature of 30 DEG C-40 DEG C for
blanching; low-temperature silk reeling is performed, and raw silks are reeled again to be arranged to obtain a finished product.
Pupa linings are manually removed from the silkworm pupae after silk reeling, so that the silk-reeling live pupae are obtained. The cocoons are not dried and cooked, silk reeling is directly performed, cost and
energy consumption are reduced, and the
survival rate of the by-products silk-reeling silkworm pupae is over 95%.
Protein,
amino acid and other kinds of
nutrient active substances of
pupa bodies are not affected, the
utilization rate of the silk-reeling silkworm pupae is increased, breeding cocoons are provided for a
sericulture department to perform orientated breeding, fine-
breed breeding is accelerated, and the technology has great significance.
