The effect of temperature and cutting time on curd yield and quality made from goat, buffalo and cow milk

For the present study, two species of lactating animals, that is, Bubalusbubalis (Buffalo) and Bosindicus (Cow) was selected. In both types of milk, highest curd yield at 34°C was obtained at 60 min of cutting time after the addition of rennet followed by 39°C at 60 min of cutting time while at 28°C and  60 min of cutting time the yield was low and cutting times. This may be due to the improper...

Infection of rose flowers by Botrytis cinerea under different temperatures and petal wetness

The effect of temperature and petal wetness on the infection of Botrytis cinerea in rose flowers was studied by combining temperatures of 10, 15, 20 and 25°C with periods of petal wetness of 8, 16, 24 and 32 h. An increase in the severity of gray mold was observed when petal wetness period increased. Lower level of disease severity was verified at 10°C for all wetness periods as well as for the temperature of...
