Abstract

The effect of prepackaging (1 percent vented High Density Polyethylene (200 gauge) bag) and pretreatments (1.5 percent potassium metabisulphite (KMS) solution (T1) and 2 percent sodium chloride (NaCl) and calcium chloride (CaCl2) solution (T2) on physiological loss in weight (PLW), total soluble solids (TSS), pH, titratable acidity, firmness and colour (L a b) of star fruit, egg fruit and fig was studied during storage in ambient (R1) and refrigeration (R2) conditions (4±1 oC). The experimental results indicated that a decrease in titratable acidity, fruit firmness, increase in pH and total soluble solids (TSS) content under both pretreatments and storage conditions. The pretreatment (T2) however extended star fruit and egg fruit marketable life with lowest PLW (8.04% and 4.52%) and physico-chemical constituents up till the 22th and 16th days at ambient temperature and more than 25th (7.47%) and 20th (3.40%) days under refrigeration condition. This might be due to the pretreatment with 2 percent NaCl and CaCl2 solution which delayed fruits ripening periods during storage. Whereas the fig pretreated with T1 had better shelf life (4 days) with respect to physical properties during storage at refrigeration temperature than control. The results of the study indicated that pretreatments T2 and T1 found to be better for improving the shelf life of star fruit (25 days), egg fruit (20 days) and fig (4 days) under room and refrigerated storage.

Abstract

Barnyard millet (Echinochloa frumentacea) is one of the hardiest millet, which is called by several other names viz., kuthiraivali (T), shama (H), shamula (M), sawank (T) and sama (G). An investigation was undertaken to develop value added barnyard millet idlis. Standardization trials indicated that incorporation of barnyard millet at 30, 40 and 50 per cent could be incorporated in the standard recipe to yield acceptable idlis with low fat 0.88g per cent. Barnyard millet rice idlis were developed and its nutritionally superior than the control idlis. Wide variations in physico-chemical characteristics of the idlis were noted. Average value of volume, weight, pH, spreadability, specific gravity, diameter and width of barnyard millet rice idli ranged from 1.40ml, 2.91g, 1.03, 0.40cm, 1.25g/cm³, 7.2cm and 2.6cm, respectively. The protein (6.82g), fibre (4.64g), phosphorus (122.01mg) and iron (4.05mg) were comparatively better than control idli. The organoleptic qualities of idlis were analysed by panellists on a 9 point hedonic scale and found to be organoleptically good.

Abstract

Millets are small seeded annual cereal grains. These are very hardy crops and can be grown successfully in Infertility lands. These crops are less prone to diseases and pests. It is stable cereals like wheat and rice, some of them are even better with regard to average protein, fat and mineral contents. Millets are particularly low in phytic acid and rich in dietary fibre, iron, calcium and B-vitamins. It also contains higher proportion of unavailable carbohydrates and release of sugar from millet is low. Over the past three decades cultivation and production of nutritious cereals is decreasing significantly, because of poverty, shifting consumption pattern from a balanced diet, widespread prevalence of nutritional deficiencies and also low consumption of nutritious cereals. But in the last two decades, grain based snack and convenience foods market had witnessed a very rapid growth all over the world.

Abstract

The current national production of soybean is around 9,81,900 tonnes in 13,01,400 hectares area. Soybean being referred to frequently as 'golden bean' or 'wonder bean' can be considered as a boon to solve protein malnutrition. The demand for soy products is consistently increasing in India as they have great potential in solving the deficiency of both energy and proteins. Soybean may become an ideal supplement because of its high protein and fat content.

Abstract

Hyaluronic acid (HA) is non-sulphated, linear glycosaminoglycans (GAGs) extensively used in biomedical, cosmetic and nutraceutical field. This type of GAGs has created a more attraction to biologists for exploration of HA from various sources. Consequently, this present study was focused towards the marine mollusk for alternative source target for the isolation of HA from the gastropod-Hemifusus cochlidium. The whole body tissues were defatted by acetone and pellet was extracted using digestion buffer followed by proteolytic treatment. Then the crude GAGs were subjected to anion exchange column for purification. Further, HA, D-glucuronic acid and N-acetyl glucosamine content was measured using the calorimetric method. Fourier transform infrared spectroscopy (FTIR) and Nuclear magnetic resonance (H¹ NMR) were used for characterization. The yield from H. cochlidium and the presence of functional group in the isolated HA was characterized by (FTIR) and H¹ NMR. In this investigation, the results suggested that marine gastropod could be an alternative source of HA.

Abstract

Cloud technology is a new computing paradigm increasing at a frenetic pace. Recently, doctors have switched to cloud computing as it provides wide storage spaces. A medical image highlights the patient's physical condition. These medical images possess a stronger correlation and larger data volume than ordinary images. Moreover, the current image encryption methodologies have several limitations during the encryption of medical images. This paper enhances the Fractional Order Lorenz System and a Matrix Scrambling Method (FOLS-MSM) for achieving medical image encryption with maximized correlation, reliability, and high resolution. In particular, the Fractional Order Lorenz System is developed by integrating the potentialities of the Arnold map, Tent map, and Lorenz Map for attaining the image encryption process. Initially, the Arnold map is used for scrambling the initial value. Then, the tent map is used iteratively to determine the state values to locate the position of the plaintext pixel. Then, the fractional Lorenz system considers the moulded pixel as the input, and scrambling is attained using a matrix method to attain confusion. Moreover, it generates the pseudo-random sequence for performing the cross-diffusion process to obtain the encrypted image. The potentiality of the enhanced FOLS-MSM explored based on security analysis with respect to sensitivity, correlation, PSNR, key space, histogram, and entropy analysis confirmed its predominance over the baseline medical encryption schemes used for comparison.
