Proximate and Vitamin Composition of Fresh and Canned Calocybe indica P & C during Storage

Abstract

The nutritional and vitamins composition of canned Calocybe indica (milky mushroom) was evaluated. The mushroom was grown under control environment with sawdust (Cola nitida) and rice bran substrate (4:1) canned in brine solution of salt and citric acid. Analysis were carried on proximate composition, water soluble and fat soluble using standard methods. The moisture, protein, ash, crude fibre, fat and carbohydrate contents (mg/100g) sample varied from 88.17± 0.01 - 93.67± 0.01, 1.28± 0.03- 3.96± 0.02, 0.33±0.03- 1.02± 0.05, 0.21±0.03-0.63±0.03, 1.73±0.03- 2.66±0.05 and 2.78± 0.04- 3.53± 0.04 respectively. While fat soluble vitamins A, D, E and K varies from 0.06±0.04 – 0.13±0.05, 0.53±0.05 – 0.59±0.02, 0.14±0.03 – 0.32± 0.03 and 0.00±0.00 - 0.03± 0.05 respectively and water soluble vitamins of vitamin B1, B2, B3, B5, B6, B12 and C varies from 0.12±0.02- 0.14±0.00, 0.75± 0.07 - 0.95±0.02, 0.15±0.06 - 0.26±0.01, 0.10± 0.02 – 0.15±0.01, 0.05±0.07 – 0.10±0.00, 0.02±0.05 – 0.10±0.00 and 0.19±0.99 – 0.53±0.03 respectively. The values recorded for fresh C.indica were the highest and lowest after one year of storage for the canned products. The properties of the canned product were relatively stable for the period of one year.
