Porosity in food

It is a good drying style to create a state of porosity on the food material. This can be achieved by whipping or foaming a food liquid or puree prior to drying or by a vacuum drier by rapid escape of water vapour into high vacuum. The major advantage of this state of dried food is that there is quick reconstitution and greater volume appearance. While the drawback of this state is shorter stòrage ability due to increase surface exposure to air, light etc and also increase bulk ...............................................

Physical classification of water

Hygroscopic water This is the water present in an air dry soil held tightly by soil solids at a suction pressure greater than 3.1 bar. This type of water cannot be removed by evapouration and roots of higher plants. Only microbial activities have been found to take place here.

Arboreal Habitat

Trunk of a Palm tree A variety of plants and animals live on and sometimes in a palm tree. The plants are epiphytes most of which live in humus and dusts which collects in the leaf bases of a palm tree. The animals are there because of these epiphytes or of the palm tree itself. A palm tree maybe divided into three regions, the crown, trunk and aerial parts of the roots. The common epiphytes found on palm trees are orchids (Diaphanthe, Bulbophyllum) figs, ferns, mosses. The animals found here are small animals like insects and spiders. You can get a soft copy of this book by sending me mail. ukponifueko@gmail.com.
