And Chemical Properties

Quality cassava(Manihotesculentus, Crantz) flour is often influenced by process variables such as slice weight and soaking time which may affect its nutritional quality. In this study, the effect of process variables (slice weight and soaking time) on quality of cassava flour was carried out. Cassava root was peeled, washed and cut into varied sizes (25.86 - 54.14 g) and soaked at varied time (7.03 - 40.97 h). The proximate composition, physical and chemical properties of the flour were carried out using standard methods. The result in our findings showed that slice weight and soaking time had significant increase (p<0.05) on the proximate and physico-chemical properties of the flour.The amylose and amylopectin content of the flour increased with increasing soaking time while the hydrogen cyanide content decreased with increase in soaking time. Overall, the quality cassava flour displayed desirable properties for its incorporation into baked goods.

Standardized milk having casein: fat ratio 0.92 was used and the processes were optimized for the manufacture of cheeses. The samples were analyzed for physico-chemical properties (moisture, total solid, fat, protein, ash, calcium, fat retention, protein retention, yield) and functional properties such as meltability, stretchability, baking quality and shreddability were also analyzed. Significant differences (p<0.05) were found in calcium content of the cheese, color and overall sensory properties. Stretchability and shreddability in relation to functional properties were also found to be significantly different. The yield for mozzarella cheese made using rennet was higher than that of cheese made using kiwi juice as milk coagulant and also it was superior in terms of overall functional properties. It was deemed that a good quality mozzarella cheese with variant characteristics can be prepared by using kiwi juice as milk coagulant.

The physico-chemical properties of commercial canned whole tomatoes (i.e., peeled tomatoes with about 30% tomato juice as packing medium) and the contribution of various analytical parameters to some sensory attributes were evaluated using multivariate statistical analysis. In addition, cluster analysis was used to determine the existence of significant qualitative differences between the old and famous San Marzano variety (as described on the commercial labels by the manufacturers) and traditional (without any specification on the tomato variety) canned whole tomatoes.

The Impact

AbstractPre-harvest operations affect the quality of food products. This study evaluated the impact of age at harvest (AH), cropping system (CS) and variety on the chemical and functional properties of high quality cassava flour (HQCF). Two white-fleshed (TMS 30572 and TMS 98/0505) and three yellow-fleshed (TMS 97/JW2, TMS 01/1371 and TMS 01/1368) cassava varieties planted either as sole crop or intercropped with maize were harvested at 12, 15 and 18 months after planting, and processed into HQCF. Chemical composition (proximate, mineral), physico-chemical properties (pH, total titratable acidity and colour) and functional properties (bulk density, water absorption index, dispersibility, swelling power, solubility index and pasting properties) of HQCF were determined. Data obtained were analysed using general linear model (GLM). AH had a significant (P < 0.05) effect on proximate and mineral composition, functional and physico-chemical properties, peak and breakdown viscosities, and peak time of HQCF. CS significantly (P < 0.05) affected the crude fibre, fat, bulk density, swelling power, mineral composition, and physico-chemical properties (except L* and b*) of HQCF. Variety significantly (P < 0.05) affected the proximate (except moisture) and mineral composition, functional properties, and breakdown viscosity of HQCF. The interactive effect of AH, CS and variety was significant (P < 0.05) on fat, dispersibility, mineral composition, and physico-chemical properties. In terms of carbohydrate content, it is desirable to harvest cassava at 12 months after planting, with TMS 98/0505 being the choice variety. Recommendation of the desirable AH, CS and variety will vary according to the desired quality of the end-products. Age at harvest is the most important single factor affecting the proximate composition and functional properties of HQCF.

Food Product Development

The utilization of plantain flour has increased in recent years as a result of its industrial potential and health benefits; hence the more quests for its application in food product development. In this study, short bread biscuit was formulated from wheat and plantain flours mixed in the ratios 90:10, 80:20, 70:30, 60:40, 50:50 and 100% wheat flour was indicated as control. The flours and the short bread biscuits were analyzed for their proximate, physico-chemical properties of the mixes and physical attributes and consumer acceptability of the short bread biscuit by sensory evaluation using standard methods. The result showed that the proximate composition values ranged from 12.41 to 14.54, 9.06 to 11.38, 1.11 to 1.51% for moisture, protein, fat, crude fibre, ash contents and carbohydrate respectively. The mineral ranged from 2.28 to 2.67 mg/100 g, 8.38 to 9.44 mg and 276 to 296.50 mg/100 g for iron, calcium and phosphorus respectively. The physiochemical properties ranged from 0.609 to 0.615 g/ml and 0.63 to 0.64 g/ml, 119.50 to 134.00 g/g, 15.25 to 17.40 g/g for loose and packed bulk densities, water absorption capacity, swelling capacity respectively. The amylose and amylopectin value ranged from 24.05 to 31.55 and 68.45 to 75.95% respectively. The value for vitamin C and B1 ranged 3.04 to 3.58 and 0.22 to 0.24 μg/100 g respectively. The proximate content of the short bread biscuit ranged from 8.65 to 9.94, 6.93 to 7.73, 65.96 to 66.74, 1.02 to 1.75, 2.25 to 2.63 for moisture, protein, carbohydrate, crude fibre, ash and carbohydrate respectively. The sensory attribute shows that short bread biscuit produced from 90:10% was well accepted.

Abstract An attempt has been made to concentrate Litchi juice using fresh juice, using class-II preservatives via laboratory scale single stage single effect glass evaporator with vacuum in a batch. Two litchi varieties viz. Dehradun and Seedless late were procured from the Regional Fruit Research Station, Gangian (Distt. Hoshiarpur) and processing was done at Food Science and Technology department (Punjab Agricultural University, Ludhiana, Punjab) pilot-plant. The extraction of juice was attempted via screw-based juice extractor with subsequent muslin cloth filtration. The filtered juice was divided into two lots of which one was concentrated via evaporation while another was preserved using 2000 ppm potassium metabisulphite in glass bottles for later on concentration. The juice was concentrated at 50-55oC temperature with a vacuum of 27-30 inches of Hg. The final concentration of juice was maintained at 80 oBrix in all the cases. Product was packed in pearl pet jars and was stored at ambient room temperature (12-38 oC) (RT) and low temperature (LT) i.e., refrigerated (0-4oC) for 6 months periodic quality evaluation like physico-chemical because of storage. Stored product was analyzed at 0, 2, 4 and 6 months interval for various storage physico-chemical changes like TSS, pH, acidity, ascorbic acid, sugars, browning, pectin, viscosity, tannins and sensory quality. The result outcome proposed that seedless variety yield more juice, pulp and less seed in comparison to Dehradun variety while the sensory characteristics were found more acceptable in Dehradun variety rather than Seedless variety. Physico-chemical properties observed in concentrates from both litchi varieties doesn’t show much difference but a clear difference can be seen room temperature stored concentrate to low temperature stored concentrate. The flow behavior for the concentrates was found to be decreasing slightly with storage period as compared to controls. However, considerable decrease in flow behavior index was observed for the concentrates prepared from Dehradun variety stored at low temperature for 6 months to the seedless variety. The consistency index values has shown positive drift with extending storage time especially for those low temperature concentrates. So, it can be said concentrates from both varieties could be commercially produced with acceptable sensory characteristics.
