Three types of weaning food named as F-1 (wheat flour, soya flour, rice flour), F-2 (wheat flour, soya flour, malt extract) and F-3 (malted wheat flour, soya flour, peanuts, lentils, and carrots powder) were prepared for the study. Nutritional quality, functional and sensory characteristics of the developed food were investigated. Functional property as water absorption capacity, bulk density, water binding capacity, solubility, swelling power and viscosity varied from 136.24-145.83 (g/100g), 0.57-0.75 (g/cm3), 410.54-471.07 (g/100g), 35.05-48.81%, 6.16-11.79%, 33.48-39.41 (mp/s), respectively.

Ash (1.95-2.16%), protein (13.45-17.04%), fat (0.55-0.78%), fiber (0.23-0.55%) and mineral contents increased with the increasing content of buckwheat flour in noodles preparation.

In this work, the effectiveness of coir pith charcoal is stated for the removal of chromium from tannery wastewater. The charcoal yield from the coir pith was 2.4%. The prepared charcoal was characterized by Fourier transform infrared spectroscopy (FT-IR). The efficiency of coir pith charcoal for chromium removal was assessed experimenting with various parameters e.g., charcoal dose, contact time, and relative pH. The content of chromium in the raw wastewater and after treatment at filtrate was 3439.2 mg/L and 14.9 mg/L, individually. In the batch experiment at optimized condition, for 75 mL chrome wastewater at 4 g charcoal dose with 15 min contact time, the chromium removal efficiency was attained 99.6%. The level of chloride (Cl-), chemical oxygen demand (COD), and biochemical oxygen demand (BOD) were significantly reduced by 65.7%, 93.7%, and 95.6%, respectively. The use of coir pith charcoal could be an alternative source for the removal of chromium from chrome containing wastewater. \u0000Bangladesh J. Sci. Ind.

Milk samples were purchased from a dairy farm (South Banasree, Dhaka, Bangladesh) and spiked at different concentrations of urea and hydrogen peroxide. Spectral data of all samples were collected using ATR-FTIR spectrophotometer. After acquisition of spectral data, they were preprocessed with transformation techniques such as multiplicative scatter correction (MSC) and savitzky-golay derivative. The predictive performance of principal component regression (PCR) and partial least-square regression (PLSR) methods were assessed by relative prediction errors and recoveries (%) were compared . PLSR shows better prediction efficiencies over PCR with R2 value 99% for urea and 95% for hydrogen peroxide.Six brands of commercial milk samples have been evaluated by this method and the samples contain 21.66-44.73 mg urea and 1.62-2.86 mg hydrogen peroxide in 100 ml milk. This method can be easily used in the quality assessment of milk. \u0000Bangladesh J. Sci. Ind.

The aim of this study was to test the antioxidant, antibacterial and cytotoxic activity and screening the phytochemical properties of methanol crude extract from two green seaweeds Caulerpa racemosa (Forsskål) J.Agardh and Ulva (Enteromorpha) intestinalis L. The antioxidant and cytotoxic activity of these seaweeds were assessed by 2,2diphenyl, 1-picryl hydrazyl (DPPH) free radical scavenging technique and brine shrimp lethality bioassay method, respectively. The antibacterial activities against Vibrio fluvialis was determined using the standard disc diffusion method. The U. intestinalis showed higher total phenolic content with the value of 149.87 ± 18.17 mg of GAE/g than 73.95 ± 16.09 mg of GAE/g of C. racemosa. However, the recorded inhibition concentration (IC50) to corresponding standards ascorbic acid of C. racemosa and U. intestinalis were 119.62 and 34.274 μg/mL, respectively. The values were statistically significant (p <0.05) compared to the reference antioxidative agent ascorbic acid. In antibacterial assay, C. racemosa extract showed higher inhibition zone (22.65 ± 0.58 mm) than U. intestinalis (17± 0.28 mm). Moreover, U. intestinalis exhibited a lower LC50 value than C. racemosa in cytotoxic activity. Phytochemical analysis revealed that these two seaweeds have alkaloids, flavonoids, glycosides, phenols, saponins, steroids and tannins. \u0000Bangladesh J. Sci. Ind.

For automatic feeding, an Arduino microcontroller board has been integrated with the designed mechanical system to control the opening and closing of the food chamber door with the help of a servo motor. An easy digital LCD programming system allows the user to set the time interval between two successive food deliveries and the number of servo rotation at each delivery to supply their desired amount of food.
