Coconut testa is an important byproduct of the coconut industry. In this study, particle size distribution, physical and functional properties of flour produced from partially coconut testa of four local cultivars namely san raman, gon thembili, ran thembili, TallxTall were compared with those of commercial hybrid (COM) using relevant procedures. Results showed that particle size distribution, physical and functional properties of flours of different coconut cultivars were varied significantly (p<0.05). The highest bulk density value was observed for SR (0.67 g/ml) while the lowest for TxT (0.54 g/ml) (p<0.05). Maximum swelling capacity (35.00 ml) and oil absorption capacity (142.67%) were recorded for COM while the least swelling capacity (20.67 ml) and oil absorption capacity (85.67%) were recorded for RT (p<0.05). The highest emulsion activity was found for COM (50.00%) while the least value recorded for SR (42.95) (p<0.05). The maximum emulsion stability was displayed by COM (54.86%) while the least emulsion stability was recorded for GT (27.51%) (p<0.05). The observed physical properties suggested that coconut testa flour of COM variety has certain advantages over others. It could be used for partial replacement with wheat flour for value addition leading to non-cereal based products.

Niruha Basti (therapeutic decoction enema) is one of the important Panchakarma procedures (five internal bio-cleansing procedures) which is the best treatment modality in the diseases caused due to not only Vata, but also when associated with other Doshas as well. The preparation of Niruha Basti comprises of step wise mixing of ingredients as described in the Ayurveda classics. In the present study, simple Erandamoola Niruha Basti was prepared by adding Madhu (honey), Saindhava (rock salt), Moorchita Tila Taila (medicated sesame oil), Shatapushpa Kalka (paste of Athenum sowa) and Erandamoola Kwatha (decoction of root of Ricinus communis) in classical method to assess the changes in particle size distribution in each step of preparation at specific intervals. The changes taken place during the Bhavana of the ingredients was observed under microscope. The Erandamoola Niruha Basti was prepared in classical method as well as contemporary methods like churner, mixer, etc., to assess the emulsion stability. Another Erandamoola Niruha Basti was also prepared replacing Madhu (honey) with egg yolk to check for emulsion stability and particle size & distribution.

The functional, sensory and cooking characteristics of noodles from blends of Acha-tigernut composite flour were investigated. The flour blends and noodles produced were analyzed for functional properties and cooking characteristics. The tiger nut flour was substituted into acha flour at 5, 10, 15 and 20% to produce Acha-tigernut composite flour which was used with other ingredients (salt and powdered ginger) to produce acha-tigernut based noodles. The functional properties of the flour, sensory and cooking characteristics of the noodles produced were determined. The water absorption capacity and swelling capacity increased from 210.59 to 215.53 (g/g) and 524.43 to 586.57, respectively with increase in tigernut flour. While oil absorption, solubility and bulk density decreases from 209.80 to 192.72 (g/g), 10.17 to 5.19 and 0.79 to 0.61 (g/ml) respectively. The swelling capacity ranged from 524.43 to 586.57 (%) with an increase in tigernut flour. The final viscosity of the samples was found to range from 2833.00to 2201.00 (m2/s). The peak properties decreased from 2680.67 to 1580.33 (RVU). The pasting temperature increases from 82.47to 87.57°C. The addition of tigernut decreased the trough, breakdown and peak time from 1730.67 to 1205.67, 985.67 to 434.67, and 5.84 to 5.71 RVU, respectively. The average mean scores for colour decreased from 6.95 to -6.30(%) While that of taste, flavor, texture and general acceptability increased from 5.55 to 6.60, 5.95 to 6.85 (%), 5.95 to 6.44 (%) and 6.70 to 6.83 (%), respectively, as the percentage of tigernut increased.

The present study was undertaken to develop bread from composite flours. Composite flours were prepared by blending wheat flour with watermelon rind flour in ratios of 100:0 (AB1), 90:10 (AB2), 80:20 (AB3), 70:30 (AB4) and 60:40 (AB5), respectively. This study was carried out to ascertain the effects of watermelon rind flour at different replacement levels (0%, 10%, 20%, 30%, 40%) on the proximate and functional properties of composite wheat bread. The results of proximate properties determination on wheat/flour blend gave low bulk densities of 0.54g/cm3 to 0.60g/cm3, high water absorption capacity of 2.389 to 3.044 g/g as well as a high swelling capacity of 5.764 to 7.610 g/g and a low oil absorption capacity of 1.608 to 2.150 g/g. The results of proximate composition of composite bread revealed an increase in % protein, % carbohydrate and % ash from 15.7% to 18.8%, 47.1% to 52.0% and 0.6% to 1.2% respectively and a subsequent decrease in % fat from 18.4% to 13.8. There was a reduction in energy density for composite bread. The functional properties of composite flours such as swelling capacity, water absorption capacity, oil absorption capacity and bulk density were increased with increase in the incorporation of watermelon rind flour with wheat flour. Thus, the results indicate that by incorporating watermelon rind flour, it is possible to enhance the nutritional quality, chemical and functional properties of bread.

A comparative study was conducted to determine the effects of heat treatment and fermentation on the functional properties of African oil bean ( Pentaclethra macrophylla: Benth ) seeds. The objective was to determine the nutritional benefits inherent therein, and the possible utilization of this plant food source as a complement in food formulation and improvement. The bean seed was broken to obtain the cotyledon, locally processed by fermentation and heat treatment, after which it was milled to obtain flour from the African oil bean. The control group of day 0 was not subjected to fermentation, but heat - treated and all other experimental groups (Day 1 - 7) subjected to fermentation and heating. The following selected physio -chemical properties were analyzed for the African oil bean seeds: water absorption capacity, oil absorption capacity and bulk densities were determined; the emulsion capacity and whipping ability were also determined. The oil absorption capacity range d from 0.66 - 1.26 g/ml; water absorption capacity, 0.76 - 1.32 g/ml; emulsion capacity, 33.33 - 64.67 g/ml, emulsion stability after one hour, 6.00 - 63.33 g/ml, bulk density, 0.40 - 0.49 g/g and whipping ability, 0.00 - 0.93 g/ml. The processing methods adopted (fermentation and heating) to improve on the functional properties of the African oil bean seeds significantly affected (p<0.05) the bulk density, whipping ability, emulsion stability and Stability after one hour of experimental samples fermented and heat treated (Day 1 - 7) compared to the Day 0 sample that was only heated while there was , however , no statistical significance recorded for the oil absorption capacity and water absorption capacity in experimental Day 1 - 7 compared to the control (Day 0) . The treatment, demonstrated improved functional properties of the African Oil bean seeds; likely to enhance the palatability of formulated foods. The treatment did not show significant improvement on the oil absorption capacity and water absorption capacity of t he bean ; however, there was enhanced oil and water functionality.

AbstractTexture, appearance, and emulsion stability of soymilk are affected by the size and distribution of suspended particles. To produce soymilk which contains all solids in the soy, whole dehulled beans were used in the study. A microfluidizer with throttling valve attachment was used to study the influence of various pressure levels on the particle size distribution of soymilk. Soymilk was processed with a continuous flow high pressure throttling (CFHPT) system to study the effects of different pressures and flow rates in the temperature rise and particle size distribution of soymilk. The results showed that there existed a significant effect of flow rate through the CFHPT on the particle size suspended in soymilk. Temperature rise was proportional to increase in pressure of the CFHPT system. Significant decrease in particle size of soymilk was obtained by increasing pressure for both CFHPT and microfluidizer. Empirical models were established between the pressure applied, volume fraction of particle size, and particle size diameter obtained for soymilk in each system.
