The improvement of adolescent nutritional status may help address the reduction of all forms of malnutrition in Bangladesh. This is because at this stage, they experience a growth spurt thus increasing the need for most nutrients, needed for growth and reproductive health. The objective of this research was to assess the nutritional status of adolescent girls in rural areas of Bangladesh and find out the associated factors that affects nutritional status. A cross sectional study was carried out among 106 adolescent girls of Nobabpur village in Comilla district. A questionnaire was developed to obtain demographic information, food intake pattern and anthropometric measures such as weight, height with measuring instruments. About 80% were found normal according to BMI where about 13% adolescent girls were malnourished, below the cut off value 18.5. Place of residence, education of adolescent girls, their family expenditure to food and improper knowledge on food and nutrition were identified as underlying causes. Nutritional profiles of adolescent girl can be improved by implementing effective nutrition education program, providing supplementary food, facilitating primary health care program and creating awareness about nutritional knowledge. Severely malnourished adolescent girl in the selected area should be identified as early as possible and brought under supplementary feeding program.
This study was done to analyze the effect of chemical preservatives on watermelon juice. Ten different samples of pasteurized watermelon juices with different chemical preservatives, termed as T1, T2, T3, T4, T5, T6, T7, T8, T9, T10 , were made which were stored at 4 - 15°C for three months. T1 and T2 were rejected soon due to spoilage. pH decreased from 5.094 to 4.017 and minimum pH content was reduced in T10 (7.87%), while maximum in T1 (57.55%). The total soluble solids (TSS) increased from 17.460% to 18.980% with maximum in T1 (51.67%) and minimum in T7 (4.88%). Reducing sugar was increased from 15.650 to 17.500% with maximum in T10 (18.22%) and minimum in T2 (5.90%). Minimum microbial load was observed in T10 (0.20cfu/ml) and maximum in T1 (>24 cfu/ml) in case of coliforms; minimum in T10 (78×105 cfu/ml) and maximum in T1 (258×105 cfu/ml) in case of total viable bacteria and same results (minimum in T10 and maximum in T1) were shown in case of fungal count. E.coli was found in T1, T2, T3 and T4 and some bacteria was found in SS agar (especially Salmonella) in T1, T2, T3 and T5. Among all the treated juice samples T10 was most effective in maintaining the sensory and nutritional quality during storage.Keywords: © 2013 JSR Publications.

The paper deals with the investigation of the fatty oil of carom seed (Trachyspermum ammi) for its physicochemical characteristics and fatty acid composition. Oil from carom seed collected from local market was extracted with n-hexane in a glass Soxhlet apparatus. Extracted oil was dark green, burning taste, spicy in odour and soluble in n-hexane, chloroform, pet. ether and benzene. Its chemical characteristic such as acid value (6.69), Iodine value (79.39), Peroxide value (457.11), Saponification value (184.32), Unsaponified matter (9.11), Free fatty acid value as petroselinic acid (48.1) were determined by conventional method. The composition of fatty oil was determined by Gas Liquid Chromatography (GLC). From GLC analysis the main constituents of fatty oil such as Petroselinic acid (89.35%), Oleic acid (5.86%), Linoleic acid (4.79%) were determined. For the better evaluation of these spices, it is necessary to know their complete chemical composition.
The present study was designed to explore the patho-physiological investigation of anorexia of cattle at Sylhet district, Bangladesh. The aim of this study has been conducted to determine the patho-physiological causes of anorexia in cattle during the study period started from September to December in Bishwanath upazila veterinary hospital, Sylhet. Anorexia is one of the most common illness among female cattle in Bangladesh. In this study, a total number of 155 diseased cattle, 100 cattle were found having anorexia due to parasitic, infectious, nutritional deficiency and unknown etiology. Results of this study showed most anorexia developed due to parasitic infestation (41%) which was determined by feces examination and observing the body condition of the animal. The female cattle developed anorexia in higher rate (67%). The early age (less than 1year) of the cattle were found mostly to develop anorexia in cattle, may be due to parasitic and nutritional deficiencies cause.International Journal of Natural Sciences (2015), 5(2) 90-92
Green technology like biodegradable films using natural polymer is an obvious need of today. Attempt of this experiment was aimed at development and characterization of a biodegradable colored film based on starch and chitosan by using Acacia catechu. Chitosan reinforced starch based biodegradable composite film was prepared by casting. The chitosan content in the films was varied from 20-80 % (w/w). Tensile strength (TS) was improved significantly with the addition of chitosan but the elongation at break (EB %) of the composite decreased. With the addition of the Acacia catechu, tensile strength of the composites improved more. The acacia content of the film was varied from 0.05-0.2(w/w). The good thermal stability of this prepared film was confirmed by thermo-gravimetric analysis. Structural characterization was done by Fourier transform infrared radiation spectroscopy. Surface morphology of the composite film was examined by scanning electron microscope (SEM) which suggested sufficient homogenization of starch, chitosan and Acacia catechu. Water uptake was found lower for final composites in the comparison to starch/chitosan and chitosan film. The satisfactory rate of degradation in the soil is expected that the final composite film within less than 6 months. The developed films intended to use as the alternative of synthetic non biodegradable colored packaging films.
