Natural Konjac Sponge with Bamboo Charcoal
Simply allow it to absorb water and rehydrate before using again Never use the sponge when dry The better care of the sponge the longer it will last Never leave the sponge in the shower or in a pool of water Your Konjac Sponge is a natural vegetable product and should last 2 to 3 months Once it starts to look tired or breaks down
Natural Konjac Sponge
Alternatively use the sponge alone to experience its unique revitalising properties Hang or place the sponge in an airy or warm dry place to dry naturally between use When dried the sponge will shrink and harden – this is natural simply rehydrate Replace sponge every 4- 6 weeks for the best results Never use the sponge without adding
Effects of Mechanically Deboned Chicken Meat (MDCM) and
Rehydration capacity which is an important factor affecting the sensory properties such as softness and smooth texture in the mouth during mastication is associated with the hysteresis of dried foods (Rahman 2008) The effect of replacing chicken breast with MDCM on the rehydration capacity of the semi-dried chicken jerky is shown in Fig 1
