Bamboo shoot is rich in vitamins, cellulose, amino acids and trace elements and has the same nutritional value as an onion and is agood source of fibre. Bamboo shoot comprises 90 percent water. Bamboos shoots are traditionally consumed more often as a fresh vegetable during their season of availability and are preserved conventionally as salted, fermented and dried products in the North-East regions of India and as salted and pickled products in the Western Ghats of Kamataka. The preservation and processing methods used for bamboo shoots are dry salting, wet saltin~preservation inbrine, canning and drying. Formulation of National Standards on various types of processed bamboo ‘shoots would assist in the manufacture and sale of standardized, nutritious and hygienically processed products. Separate Indian Standards are being formulated to cover the requirements of canned bamboo shoots, dehydrated bamboo shoots, dry salted bamboo shoots, bamboo shoots inbrine and bamboo shoots in plain water. This standard provides guidelines for storage and transportation of bamboo shoots. Due consideration has been given to the Prevention of Food Adulteration Rules, 1955 and Standards of Weights & Measures (Packged Commodities) Rules, 1977. However, this standard is subject to restrictions imposed under these, wherever applicable. For the purpose of deciding whether aparticular requirement ofthis standard iscomplied with, the final value, observed or calculated, expressing the result of atest or analysis, shall be rounded off in accordance with IS 2:1960 ‘Rules for rounding offnumerical values (reviseo’. The number of significant places retained in the rounded off value should be the same as that of the specified value in this standard.
