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

The present work is designed to study the physico chemical, functional, pasting properties, and nutritional composition of selected black gram varieties. (viz., VBN 3, VBN 4, VBN 5, VBN 6, ADT 3, T9, MV, TMV, VBg010 025, VBg010 024, VBg09 005 and CO 6). Thousand grain weight of the selected black gram varieties was recorded to be 33.20 to 40.45 g, seed volume 38.66 to 40.2 ml, seed colour ranged as black, dull black and black and dull black, bulk density 0.06 to 1.07 g/ml, water absorption index 151.00 to 155.10 g/100g, water solubility index 13.0 to 15.6 g %, water absorption 36.6 to 56.6 ml/100g and oil absorption 40.1 to 66.2 ml/100g. The moisture values were in the range of 9.6 to 11.6 g/100g, ash 6.1 to 6.7 g/100g, protein 25.5 to 28.5 g/100g, fat 4.4 to 5.6 g/100g, starch 51.3 to 47.7 g/100g, calcium 106.66 to 134.00 mg/100g, iron 3.0 to 4.4 mg/100g and phosphorus 376.00 to 416 mg/100g. It was observed that black gram varieties, VBN 5, VBg 010 025, CO 6 and T9 had high 1000 grain weight and bulk density. Variety VBN 5 and T9 had higher foaming stability, foaming capacity, peak viscosity, final viscosity, hold viscosity and set back value. Also higher levels of protein, starch, calcium, iron and phosphorus was observed in VBN 5 and low amount of fat and ash .Vamban 5, VBg010 025 and T9 were observed to have good physicochemical characteristics and are hence suitable for further breeding and processing as value added products.

Abstract

The physico-chemical and functional properties of selected millets (viz., kodo millet, little millet, proso millet and pearl millet) and pulses (viz., horse gram and soybean) were studied. Millets are good sources of energy, protein, fatty acids, vitamins, minerals, dietary fibre and polyphenols. Thousand grain weights of the selected millets was found to be high in pearl millet (11.39 g/100g) compared to kodo millet, proso millet and little millet (2.45, 2.43 and 2.23 g/100g, respectively) and in pulses the highest and lowest values were observed in soybean (146.03 g/100g) and horse gram (34.25 g/100g) respectively. Bulk density of millets and pulses was recorded to be high in pearl millet (1.75) and soybean (1.96) when compared to the other grains. Water absorption index was high in wheat flour (9.10%) while the water solubility index was high in pearl millet flour (9.62%) respectively. The protein content was maximum in proso millet (12.86 g/100g) and soybean (42.72 g/100g) followed by pearl millet, kodo millet, little millet and horse gram. Fat content was low in all the millets and it was maximum in soybean (18.80 g/100g). Among the four millets the fiber and ash contents were high in kodo millet followed by little, pearl and proso millet. Also higher levels of calcium, iron and phosphorus were observed in millets and pulses.

Abstract

Objectives: An effective feature extraction and segmentation model is employed for palm print images to improve accuracy, computation efficiency and robustness of palm print features. Methods/Analysis: The novel Gaussian Measure Curve let based Feature Segmentation and Extraction (GMC-SE) method is introduced for removal of unwanted execution time by using Edge Based Tangent (EBT) model. In addition, to improve the computation efficiency of features being segmented, competent Gaussian measure is obtained by integrating both local and global palm print features. Findings: Experiment is conducted using Poly U 2D palm print database to measure the effectiveness of the proposed work in terms of execution time ratio, computation efficiency, feature extraction accuracy and robustness in palm print recognition. The proposed scheme GMC-SE method is compared against the existing Fine Ridge Structure Dictionary (FRSD) and Personal Identification using Left and Right Palm Print images (PI-LRPP). As a result, the GMC-SE method improves the computation efficiency by 12% compared to existing FRSD model. Conclusion/Application: An effective feature extraction and segmentation are analyzed for palm print images and experimental results are compared. GMC-SE method for palm print images handled different images in an efficient manner compared to existing works.
