Product Description

 

Product Description

Zinc Sulphate Heptahydrate

 

Zinc sulphate Heptahydrate contains 21% Zinc and used to supply zinc as micro nutrients in animal feed and fertilisers. Zinc sulphate, like many zinc compounds, can be used to control moss growth on roofs. 

 

It take part in the making of chlorophyll, auxin & growth hormones. Zinc deficiency can be detected by the weakness of the apex of leaves, strange leaf lengthening and shortening of inter nodes, leaf vein chlorosis and delay of the plant growth.

Zinc sulphate Heptahydrate can be used to supplement zinc in the brewing process. Zinc is a necessary nutrient for optimal yeast health and performance, although it is not a necessary supplement for low-gravity beers, as the grains commonly used in brewing already provide adequate zinc. It is a more common practice when pushing yeast to their limit by increasing alcohol content beyond their comfort zone. Before modern stainless steel, brew Kettles, fermenting vessels and after wood, zinc was slowly leached by the use of copper kettles. A modern copper immersion chiller is speculated to provide trace elements of zinc; thus care must be taken when adding supplemental zinc so as not to cause excess. Side effects include "...increased acetaldehyde and fusel alcohol production due to high yeast growth when zinc concentrations exceed 5 ppm. Excess zinc can also cause soapy or goaty flavors."
