Flame dried and smoked small economic fish species (Puntius spp., Amblypharyngodon sp., Lepidocephalus sp., Channa spp., Trichogaster (Colisa) spp., Danio spp., Mastacembelus spp., Mystus spp., Rasbora spp., etc.) and petioles of arum (Alocasia macrorrhiza) are ground together, packed in bamboo container and fermented for about 30 days to prepare the product. The complete process involves 11 distinct steps and the end product is preserved in the fermenting bamboo container itself by keeping it suspended over a fire place. It is consumed after steam cooking or after preparing some curry along with vegetables. Protein rich fish is balanced with carbohydrate content in the product, probably increasing the dietary fibre content as well, when it is supplemented with arum petioles. In addition, the product is the outcome of a wonderful traditional technology which combines three well established food processing techniques –drying, smoking and fermentation and also a compatible means of preserving fish for scares-fish seasons as a partial solution to protein malnutrition.

In recent years a number vegetables. This is a useful traditional method of of ethnic foods and food products traditionally processing small economic fish varieties abundantly prepared by different tribes/communities of the region available during the rainy season for consumption has been reported1-11 including fish products such as during winter and pre-monsoon months. In the present shidal/seedal6,5, ngari1,11, hentak1,11, and tungtap5,11. communication, we are describing the common method Although many fish based ethnic foods of the region of preparation of numsing together with the traditional have already been reported, numsing (a traditional knowledge system associated with the product. fish product popular among Mising community) is yet to be scientifically explored. The Misings are a Methodology Mongoloid tribe inhabiting the districts of Dhemaji, Adopting PRA (Participatory Rural Appraisal) North Lakhimpur, Sonitpur, Tinsukia, Dibrugarh, method, an extensive field study was conducted in Sibsagar, Jorhat and Golaghat in Assam (plain area) Dhemaji and North Lakhimpur districts of Upper and East Siang, Lower Dibang Valley and Lohit Assam (Northeast bank of river Brahmaputra) (Fig. 1) districts of Arunachal Pradesh12. The Misings during 2011 in order to document the traditional traditionally live in thatched platform dwellings, with knowledge system associated with numsing stilted floor (usually constructed with split or flattened production. These two districts have highest Mising —————— population in Assam. Five Mising villages from each *Corresponding author district were surveyed and the persons actively 92 INDIAN J TRADITIONAL KNOWLEDGE, VOL 12, NO. 1 JANUARY 2013 Fig. 1—Map showing study area in Assam engaged in numsing production were interviewed after taking the PIC (Prior Informed Consent) from them in writing. The women were given priority for interview and documentation, since they usually prepare the product. From the many variations of the numsing preparation procedures adopted in the study Flow chart 1—The method of numsing preparation region, a common method of preparation of the with a height of 3-4 feet and having a fireplace at its product has been worked out after eliminating bottom. Fish are spread on it and heated with nearly a insignificant deviations having little bearing on the smokeless fire that is created by burning fire woods or finished product quality. In addition, the preparation dry bamboo at the fireplace mostly during night method of the product, the method of storage and hours. Drying and smoking is continued with mild methods of preparation of dishes by using the product flame until the fish become moderately hard. Arum were personally observed. petiole slices are sundried for 1 day. Observations Step 4. Mixing: The flame dried fish and sundried Method of preparation of numsing: Numsing is a arum petiole slices are mixed together in the ratio of semi dried and semi smoked paste like product prepared 4:1. Other spices such as red pepper, green chili, by mixing fish, petioles of arum and spices. ginger and garlic may also be used according to the The different steps (Flow chart 1) followed by the tribe taste. However, no salt is used. for preparation of the product, are briefly described: Step 5. Grinding: A foot operated elongated Step 1. Selection of raw material: Small traditional wooden grinder or huller (locally called economic fish species of assorted size abundantly dhekee) is used to grind the mixture. Dhekee is a available during the South-west monsoon season household apparatus in Assam that is usually used for (June-September) in the study region (Table 1) are hulling rice and grinding spices (Fig. 3). In used for preparation of the product together households that lack dhekee, a smaller hand operated with petioles of elephant ear or arum (Alocasia traditional wooden grinder/huller pot with a wooden macrorrhiza) belonging to the family Araceae, locally thrasher (uraal) (involves higher drudgery) is used for known as mana kasu (Fig. 2). It is a herbaceous grinding and mixing the ingredients (Fig. 4). Grinding perennial plant having broad leaves and a large continues until the mixture becomes coarse paste. rizhome on or just below the ground. Step 6. Stuffing: The ground mixture, which is by Step 2. Dressing and cleaning: The fish are now a coarse paste, is stuffed tightly in a bamboo dressed to remove gills, scales and intestine and container (bahor chunga) keeping headspace of about washed with clean water. The edible part of arum 10-15 cm for subsequent sealing. The container is a petioles is sorted out, peeled and sliced using kitchen single internode of immature bamboo (Bambusa spp., knife (kotaari). less than one year old) that is made by retaining one Step 3.
