The aim of the present study is to evaluate the influence of wet digestion methods on Iron and Vitamin C estimation method from five different combined juices such as Solanum anguivi L. (S); Emblica officinalis (E) juice; S1:E3; S1:E1 and S3:E1. The samples were digested with different acid digestion methods namely method A (aqua regia), method B (only nitric acid), method C (only hydrochloric acid) and method D (Non digestion) determined by atomic absorption technique; to recommend the most efficient digestion method that gains the highest analyte recovery. The vitamin C was also determined by three different methods of 2,4-dinitrophenyl hydrazine, Iodometric method and 2,6-dicholorophenol indophenol method to find the accurate results. Present study revealed that method A (aqua regia) obtained the highest analyte recovery; similarly, vitamin C was also found as high where determined by 2,6-dicholorophenol indophenols respectively.

Methodology: The fresh fruits of S. anguivi (S) and E. officinalis (E) were weighted at five different proportions such as S1-100g:E0-0g; S0-0g:E1-100g; S1-25g:E3-75g; S1-50g:E1-50g and S3-75g:E1-25g. Each combination was ground using a domestic mixer to extract the juice without adding water and analyzed for its characteristics such as color value, browning index, and acceptance level through a sensory evaluation which was recorded at two different intervals (0 and 90 min). Results: Overall color analysis (DE*) indicates that E. officinalis juice significantly reduced the enzymatic browning reaction by its concentration and postponed the brown color development in all three combinations of extracted fruit juices during the storage period. Although, the browning index was high in all the combinati...

(S) with enriched vitamin C from Emblica officinalis (E) through a spray-drying process. Fresh juice of Solanum anguivi L. and Emblica officinalis (S1:E3) were extracted and dried using three different carrier agents (Gum Acacia, Maltodextrin, β-Cyclodextrin at 15%) in a laboratory scale spray dryer with 130°C and 60°C drying temperature were maintained. The developed juice powders were analyzed for encapsulation efficiency, yield, bulk properties, reconstitution properties, hygroscopicity, degree of caking of the particles and color attributes. The results procured that Gum Acacia and Maltodextrin encapsulated powders improve drying yield, encapsulation efficiency and moisture free which is the most effective, whereas the reconstitution properties and bulk properties revealed that β-Cyclodextrin encapsulated powder obtained better results. However, the percentage for a degree of caking and hygroscopicity was elevated which was influenced by ambient temperature and resulted in stickiness. Thus, S1:E3 juice powder encapsulated with Gum acacia, Maltodextrin and β-Cyclodextrin is seen with wholesome quality in terms of its physical properties.

The Government has introduced such programs like Mid-day-Meal program to overcome under nutrition. The present study was conducted in Government aided middle schools in rural area of Sankarankovil, Tirunelveli district. Methods: The subjects around 200 were randomly selected and the detailed information was collected regarding socioeconomic status; nutritional status includes anthropometry, clinical and dietary pattern by direct interview method and data was statistically analyzed. Results: The results revealed that most of the children belong to a low income family group; anthropometry measurements suggest that children had significantly lower mean values compared to the standard, though it revealed the school children were undernourished. Dietary pattern and consumption of iron intake was also found to be very low. Conclusion: Nutritional status has to be improved by dietary modification, iron supplementation and nutrition knowledge.

Objectives: Identification of osteopenia and osteoporosis in young female adults.
Materials and Methods: Target population was young female adults (N=500) taken from five private ladies hostels located at urban area of North Coimbatore. The Bone density of all the participants was measured by Quantitative Ultra Sound (QUS) method and the values were compared with WHO T–score and classified as either normal or osteopenia /osteoporosis.
Results and Discussion: The mean height of the subjects varies from 150.93±6.40 cm to152.32±5.92 cm lower than the standard value suggested by NCHS (2008). The mean weight of the subjects ranged from 50.78±7.71 kg to 52.40±7.77 against the standard value of 54.4 kg. Based on weight 5.45%, 13.8% and 77.4% of the subjects were obese, overweight and normal respectively when compared with standard value. The body fat content of about half of the study population was between20-35% and 38% had high bodyfat (31–40%) while the remaining had below 20%.The metabolic rate of half of the subjects was between 1100-1300.Out of the 500 assessed for BMD by QUS 193 were osteopenic and 51 were osteoporotic which could be due to the sedentary lifestyles adopted by them. Identification of those with low bone mass will help in early institution of intervention strategies and thereby prevent the risk of osteoporosis
