ABSTRACT
The present investigation entitled, “Processing of tender bamboo shoots for
edible products” was conducted during the year 2011-2012 in the department of Food
Science and Technology, Dr Y S Parmar University of Horticulture and Forestry, Nauni,
Solan (H P). Three species of edible bamboo shoots viz. Dendrocalamus strictus (S1),
Dendrocalamus hamiltonii (S2) and Bambusa nutans (S3) were used for conducting the
study. The quality analysis of these species showed that moisture content, protein and
Vitamin C varied from 85.36-93.01, 3.00-3.70 per cent and 5.00-20.00 mg/100 g in S1, S2
and S3, respectively. Among the three species, Dendrocalamus hamiltonii was observed to
be the best with respect to chemical evaluation. This variety is available locally and grown
widely which generally is not utilized for processing into edible products. The Hydrogen
cyanide (HCN) content was 43.05, 64.80 and 51.30 mg/100 g in S1, S2 and S3, respectively.
Different treatments were used for the reduction of HCN out of which T1 (Pre-soaking for
long time in water and boiling for 90 minutes ) was found to reduce HCN up to a level of
99 per cent. Keeping in view the availability and nutritional value of locally grown bamboo
shoots, efforts were made to develop and standardize various value added products viz.
pickle, chutney and candy. Standardized products were evaluated for their quality attributes
and storage stability. Results showed that B.nutans was found to be the best for pickle and
chutney preparation, while D.hamiltonii was best suited for candy making. Storage studies
revealed that all the products can be stored well up to a period of six months at ambient
temperature. The results indicated that the bamboo shoots can be successfully utilized for
the preparation of edible processed products viz. pickle, chutney and candy which can add
a variety to the horizon of food industry.
