The present investigation was carried out to evaluate the feasibility of fortification of soymilk with standardized milk for the production of fortified nutritive milk formulation. The functional properties of cattle milk can be enhanced by blending of soy milk. The soymilk was obtained by using standard procedure by grinding soaked seeds of soybean with hot water (bean to water ratio, 1: 4 w/v). In the present study three formulations of soy and standardized milk were prepared as follows T<sub>1</sub> (100% soymilk), T<sub>2</sub> (50% soymilk: 50% standardized milk), T<sub>3</sub> (60% soymilk: 40% standardized milk), and T<sub>4</sub> (70% soymilk: 30% standardized milk) and Control as T<sub>0</sub> (standardized milk). The changes in physico-chemical, sensory and rheological properties were recorded. The results revealed that overall organoleptic acceptability scores of formulated milks formulations were 6.9, 8.06, 7.65, 7.04 and 8.49 for the formulation T<sub>1</sub>, T<sub>2</sub>, T<sub>3</sub>, T<sub>4</sub> and T<sub>0</sub>, respectively. Fat, total solids, titratable acidity, pH, ash and solid non fat content were decreased with increasing soymilk proportion, while moisture and protein content were increased. The blending of different ratio of soymilk with standardized milk had significant affect on colour attributes (L*, a* and b*). Yellowness and greenness increased while lightness decreased as the proportion of soymilk increased.

Twenty-five samples of spray dried whole milk powder (WMP) of different brands were procured from five regions of Maharashtra namely Vidarbha, North Maharashtra, Western Maharashtra, Marathwada and Mumbai. These samples were analyzed for the chemical composition, physico-chemical properties and microbiological quality to access their suitability in terms of national and international standards. The moisture, fat and protein content in WMP obtained from different regions varied significantly.Wide variation in the physical properties like scorched particles, wettability, dispersibility and solubility index was observed in WMP. The NPN, true protein content, titratable acidity and lactate content and free fat content of WMP samples were varied significantly. The standard plate count and coliform count of WMP samples were lower than that of the standard prescribed by BIS and PFA. In the present study except few, all the samples meet the requirements of national and international standards.

Quality is a wide-ranging concept determined by many factors. It is a composite of those physical and chemical properties of the material which govern its acceptability and processing suitability. This study aimed to determine the physico-chemical and functional properties of the two jackfruit varieties (EVIARC Sweet and AES-2) grown in Eastern Visayas, Philippines. Fresh ripe jackfruit varieties were subjected to physico-chemical properties and functional component analyses following standard protocols. The two jackfruit varieties were found to have the following properties: the pH were 4.80 and 5.50; total soluble solids (TSS), 24.00 and 22.60oB; total titratable acidity (TTA), 0.33% and 0.12% citric acid; moisture content (MC), 77.30% and 75.96% (wb); total phenolics (TP), 127.73 and 125.91mg CE/100g; tannin content (TC),127.73 and 208.72 mg VE/100g; total reducing sugar (TRS), 15.43% and14.38%; total sulfur (TS), 0.36 and 0.57ppm; and antioxidant activity (AOA), 39.55 and 52.35% LP (lipid peroxidation) for EVIARC sweet and AES-2, respectively. Variety significantly affects the pH, TSS, TTA, %MC, TC, TRS, TS and AOA. Non-significance was noted on their TP contents.

The study was conducted to develop frozen yoghurt, flavoured with jackfruit pulp. Sensory data revealed that, the sample incorporated with 15% jackfruit pulp had the best qualities. Protein content of all jackfruit pulp incorporated frozen yoghurts was significantly higher (p 0.05) and their fat content was significantly lower (p 0.05) compared to the control. Significantly higher (p 0.05) overrun was observed in the frozen yoghurt containing 20% of jackfruit pulp compared to the control. Titratable acidity increased and pH decreased in all samples during the storage. Though total plate count of all jackfruit pulp incorporated frozen yoghurts increased upon storage, it was less than that of the control. Escherichia coli, yeast and mould were not detected for a period of 35 days at frozen storage. In conclusion, physicochemical, microbiological, and sensory properties of frozen yoghurt improved significantly by adding jackfruit pulp at rate of 15% (w/w).

Comprehensive Study

Quinoa is recently gaining more interest from many countries as a nutritious substitute and food addition. Proximate chemical analysis of quinoa flour (QF) was estimated. Additionally, the rheological properties of balady bread dough fortified with QF were evaluated. It was found that QF was an ideal source of minerals especially potassium (808.7 mg/100 g) and essential amino acids compared with wheat flour. Moreover, the protein content of bread substituted with QF increased by increasing QF content. Also, the sensory properties of bread were acceptable. There was no noticeable difference (P≤ 0.05) between bread fortified with 10% and control sample. The gluten levels went down by raising the levels of QF from 10 to 40% whilst; the protein content increased from 10 to 40% by rising QF replacement levels. The obtained date suggested that QF could be utilized as fortifying source of protein and nutrients especially, in bakery products.

Background: About one third of the maize production is imbibed in the form of flat breads or chapati which is consumed basically in the northern states of India. Maize flat breads are generally prepared with hands, owing to lower gluten content and lower binding properties it is difficult to prepare. In the present study the effect of blending composition of wheat and gram in maize flour on physico-chemical and functional properties were investigated.Methods: The maize flour of PMH–1 variety was blended with wheat and gram flour in different combinations of (20, 30 and 40%). The composite flours were evaluated for different physico-chemical properties like moisture content, protein content, crude fat, crude fibre, ash content, carbohydrates, titrable acidity, color value, titrable acidity, swelling power, oil holding and water holding capacity. Result: It was observed from the study that the protein content (2.83±0.02%), fat content (6.13±0.02%) and fibre content (2.82±0.02%) was higher for gram blended flour than wheat blended flour. The swelling power of the flour blended with wheat was found out to be higher (30.74±0.01%), than blended with gram flour (25.30±0.01%), whereas the oil holding and water holding capacity of wheat blended and maize blended flours was similar.

The effect of infrared radiation (IR) on the physicochemical characteristics, pectin methylesterase activity (PME), hydroxymethylfurfural (HMF) content, microbiological activity, color, and sensory aspects on black lime juice was studied. IR was compared to conventional thermal heating (CTH) in batch infrared extraction pasteurizer, designed to allow both infrared and conventional heating. IR resulted in a reduction in pH and Brix values and a mild increase in titratable acidity, as compared to CTH and control. After 60 days at 5 °C, the ascorbic acid percentage was decreased by 24.90%, 29.75%, and 58.31% in the control, IR and CTH, respectively. The total amount of phenols in juice treated with IR was higher as compared to CTH and control, while there was a significant decrease in the antioxidant activity. The statistical analysis reflected significantly low (p < 0.05) activity of PME for IR samples as compared to CTH and control. The amount of Hydroxymethylfurfural (HMF) in all juice samples steadily increased during the storage at 5 °C in 60 days. The microbial content of control was 3.85 log cfu/mL after 60 days at 5 °C, while it was 2.1 log cfu/mL for IR which reflected a significant difference between the IR, CTH, and control samples. Additionally, color and sensory analysis of IR treated sample when compared to control, reflected similar attributes. Overall, IR was found to be an excellent substitute for the preservation of black lime juice as a rapid pasteurization technique with less heat exposure; wherein the nutrition and health benefits of the juice could be maintained for a minimum period of 60 days.
