PROCESSING OF GINGER POWDER

Moisture content (%)

Powder	1^st test during packaging	2nd test after 2 months		3^rd test after 4 months	4^th test after 6 months
Sun dried	5.72		6.1	6.8	7.5
Oven dried	4.35		5.1	5.9	6.8
Sun and oven	4.0		4.6	5.4	6.5

By determining moisture c ontent, it was observed that the samples that are pac kaged in plastic c ontainers and c apped had the lower moisture c ontent than the samples packaged in polythene bags. The ginger powders that are opened sometimes was observed and fo und that the moisture c ontent was inc rease d comparatively more . For increasing moisture c ontent, the keeping quality of ginger powder would be decreased. So , Capped plastic container is comparatively better than polythene bag as a packaging material for storage purpose of ginger powder under ambient temperature .
Cost analysis: The c osts of gingers and ginger powders were analyzed to determine the feasibility of marketing and consumer ac ceptanc e . Total cost for preparation of ginger powder from 5 Kg fre sh gingers:
Table 5. Cost a na lysis of ginger powder production
Item Cost ( Tk.)

Ginger (5 Kg)	400
Fixe d c o st	20
Labo r (1)	130
Others	50
Total	600

In general, the approximate value of 1 kg ginger powder is 1050 Tk. So the market va lue of 950 gm ginger powder will be 997.50 Tk. Ac c ording to cost a na lysis, ginger powder production is commercially profitable.
