RESUMO
A ready-to-eat nutritious snack mix was developed by blending the flour from popped millets and legumes with sugar and other ingredients in the optimized proportion of 30:20:27:23. The nutrient composition, functional properties, sensory qualities and storage characteristics of the product were analysed. The product contained protein 14.0 ± 0.07 g, fat 14.5 ± 0.72 g, carbohydrates 59.0 ± 1.20 g and dietary fiber 6.3 ± 0.04 g per 100 g of mix. The sensory evaluation of the product revealed that color, taste, texture, aroma, appearance and overall quality were in acceptable range with mean score of 6.8. Shelf life of the product was about 90 days under normal conditions when stored in low density polypropylene pouches. The work indicates the potential of using coarse cereals and legumes for preparation of nutritious food for societal program.
RESUMO
Nutrition support has become an important therapeutic intervention for improving outcomes in hospitalized patients. The present study was carried out with the objective of studying appropriate packaging and storage studies of enteral formulation from natural sources comprising finger millet (Eleusine coracana), soyprotein isolate, tomato powder, carrot powder, anne greens (Celosia argentea), groundnut oil and fish oil. Two type of packages--namely, polypropylene pouches and metallized polyester/polyethylene pouches--were used. The storage conditions were 27°C and 42°C at 65% relative humidity. The chemical, microbiological and sensory qualities of the formulation were assessed at regular intervals. The moisture sorption studies revealed that the formulation had an initial moisture content of 3.59%, which equilibrated to 13%. The product was acceptable at 64% relative humidity, after which it tend to become soggy. Analysis of peroxide value and free fatty acid content of the equilibrated samples revealed that moisture content of 4-5% was ideal for the storage of the formulation. An increase in the peroxide value and free fatty acid content was observed during 90-day storage period but the formulation was organoleptically acceptable. The microbial analysis of the formulation revealed an initial total bacterial count of 1.5 × 10² colony-forming units and increased to 7.9 × 10² colony-forming units (polypropylene) and 5.0 × 10² colony-forming units (metallized polyester/polyethylene). No fungal and coliform was detected at 90 days of storage. Thus it was concluded that the formulation can be stored for a period of 3 months at 27°C and 65% relative humidity. Such formulations can be primarily a supportive strategy to an active therapeutic intervention.
