Abstract:

Fish is important food component as a source of protein and microelements necessary for the maintenance of healthy body. The greatest risk to human health occurs due to the consumption of raw, inadequately cooked or insufficiently processed fish and fish products. There are more than 100 individual species in the Vibrio genus, only some species cause foodborne infection. The main goal of this work is to identify pathogenic species of Vibrio in five species of fish (Caspian Carp, zander, Caspian kutum, Caspian sturgeon, salmon) from river and sea of Azerbaijan Republic and to study the dynamics of Vibrio infestation in fish depending on the season. To identify pathogenic forms of , was used PCR Real Time method on the Dupont Bax System Q7, manufactured in the USA. The method allows identifying simultaneously three types of pathogenic forms of Vibrio; V. parahaemolyticus, V. vulnificus and V. cholerae. Studies were conducted from January 2017 to May 2019. During this period Vibrio were determined in 76 local fishes (Carp, zander, Caspian kutum) caught from river during May till September months, that pointed increasing the number of bacteria of this family during the summer season, when the temperature of water increase from +20 °C to +25 °C, contributing to significant irritation and the accumulation of Vibrio bacteria in fish. There were not detected any Vibrio bacteria in sea fish (Caspian sturgeon, salmon), that may explained by high water salinity in sea.

Abstract:

Fruits and vegetables processing industries produce massive waste that possess environmental problems due to their volume, but the by-products like peels and seeds has been recognized as potential source of bioactive compounds, thereof food processing waste may be used to develop the functional food products. The present study focused on the preservation of pea pod by drying at 60°C for 5 hours and nutritional characterization of powder. Pea pod powder was rich in fiber (45 g/100 g), bioactive components (84% inhibition of DPPH and 1.07 g/100 g GAE total phenols) and minerals (calcium 6.032 mg/g; phosphorus 1.623 mg/g). Amino acid composition of powder was also analyzed using GC-MS and it was observed that all amino acids were present in significant concentration but phenylalanine (14.80%), histidine (14.80%) and tyrosine (36.30%) were slightly higher. Sugars, proteins and ascorbic acid were found in considerable amount, but powder also contained small amount of anti-nutritional factors (saponins 1.068 mg/g; tannins 0.095 mg/g). Pea peel powder exhibited good water absorption capacity, water solubility and swelling power. Due to its nutritional and functional properties, it could be incorporated into certain food products to enhance their nutritional value.

Abstract:

Gelatin has many applications in the food, pharmaceutical and nutritional industries supported by its excellent properties and functionalities. Gelatin is a mixture of polypeptides obtained by hydrolysis of collagen primarily from bovine and porcine skin and bones. Since gelatin can be derived from different animal species, the source of authentication is necessary for products containing gelatin due to religious (Muslim halal, Jewish kosher) or health reason. The similarity between different gelatins makes it difficult to trace their species origin. We at Dubai Central Laboratory developed and validated a fast, robust and reliable method for differentiation between bovine and porcine gelatin based on detection and identification of marker peptides in digested gelatins. Porcine was extracted from an aliquot of pharmaceutical capsules, marshmallow and other food matrices using simple extraction technique and injected into a Liquid Chromatograph equipped with a Tandem Mass Spectrometry (LCMS/ MS) detector using the Multiple Reaction Monitoring (MRM). The validated method demonstrates acceptable performance and is suitable for the determination of porcine gelatin in pharmaceutical capsules, marshmallow and other food matrices over the concentration range of 0.25% to 100.00%. This will help alleviate ethical concerns of the source of gelatin used in food manufacturing and pharmaceutical capsules used to deliver drugs. The overall impact of the analysis will help to ensure public health and safety, which is one of the strategic plans of Dubai Municipality.

Her present research investigation is focused on assessing the potential of various rice cultivars in the formulation of instant indigenous food mix native to India.

Abstract:

The objective of present investigation was to assess the dimensional and functional characteristics of the eminent Indian cultivars (PR-114, PR-121, PR-122, PR-123, PR-124, PR-126 and PR-127). Dimensional (geometrical) properties such as length, width, thickness, equivalent diameter, surface area, aspect ratio, volume, bulk density, true density, porosity, thousand kernels weight, angle of repose and coefficient of friction were evaluated which play a critical role in designing an efficient framework for various post-harvest unit operations and storage structures. Cultivars like PR-121 and PR-126 manifested low bulk density due to the presence of long awns that in turn resulted in more space occupancy. A noteworthy variation was observed in the brown rice kernels that play a crucial role in governing the functional properties and estimating the energy prerequisites during polishing of these cultivars. Results indicated significant differences in the dimensional properties among various paddy and brown rice cultivars when compared with earlier reported results. Thousand kernel weight, width, arithmetic mean diameter and equivalent diameter showed significant positive correlations with sphericity, surface area, volume, true density and angle of repose; but negatively correlated with bulk density. A significant variation was testified in the functional characteristics such as rheological properties, water absorption capacity, swelling power, oil absorption capacity, emulsion and foaming capacity and emulsion and foaming stability of the brown rice flour obtained from these cultivars. These broadly diversified and anticipated dimensional and functional characteristics of the Indian cultivars not only establishing the foundation to preserve these races as well as encourage the farmers to cultivate these cherished rice cultivars.

Abstract:

Major uses of pesticides are in agricultural and farm pest control. Pesticides are also used for controlling household pests like flies, cockroach’s etc., in public health for mosquitoes and other vector control. Pesticides enter human system mainly through the food, followed by inhalation and polluted environment. UAE is importing majority of its food items; control of pesticides can be achieved mainly through import control. Dubai central laboratory is monitoring the pesticides for the last ten years in various food items likefruits, vegetables, milk, spices, cereals, pulses, honey and fish etc. Important findings of the survey are fruits, vegetables and spices contain more pesticides than other food commodities. We also found that specific commodity-pesticide combination in the survey. We propose targeted control measures are required for the reduction in pesticide residues.

I did my schooling from a local convent school. After school, I did my bachelor’s degree in home science and and my master’s and doctorate in food science and technology. As a teacher I have taught many courses in the field of food technology and to name them a few; processing of cereals, pulses and oilseeds, processing of fruits and vegetables, sensory evaluation of foods, food packaging. My area of interest of work is developing foods for diabetics and celiac patients as there has been a tremendous rise in population suffering from these two diseases over a period of last decade. I have developed gluten free pasta from little millet and an energy bar with quinoa as a major ingredient for celiac patients. Flour with low GI for making chapati was developed which has been commercialised. I plan to continue working on these type of products.

Abstract:

Quinoa based bar was developed using quinoa, brown rice, flaxseed and nuts and honey (50%) was added as a sweetener and binding agent. The shelf life of bar was assessed in Aluminum Laminates (AL) and High Density Polyethylene (HDPE) bags stored under ambient temperature conditions for 4 months. The stored bar samples were analyzed for moisture content, peroxide value, free fatty acid and sensory quality. Significant variation was noticed in the free fatty acid and peroxide value of cereal bar stored in HDPE packaging material as compared to aluminum laminate bags. However the increase in Peroxide Value (PV; 1.69%) and Free Fatty Acid (FFA; 0.96%) was lesser even in HDPE bags than the prescribed limit. The data related to PV, FFA, moisture content and organoleptic quality of bar using different packaging materials during storage revealed that, the bar remained stable and acceptable for 4 months at ambient conditions irrespective of the packaging materials used. However AL was found to be better packaging material as compared to HDPE because of the better retention of chemical and sensory quality. Product was acceptable after the storage period of 120 days.

Fresh bell pepper, dried bell pepper and paste were used in bread at different substitution levels: Dried at the levels of 1.5%, 2% and 5%; paste at the levels of 10%, 15% and 20% and fresh bell pepper at the levels of 10%, 15% and 20% (wt/wt of wheat flour). The dried powder at the level of 1.5%, paste at the level of 20% and fresh bell pepper at the level of 20% were selected for product formation as they provided good texture, good flavor, better product quality and high nutritional value. The product was analyzed for various quality characteristics viz. total phenols, antioxidants, protein, fat, ash, moisture and texture, crude fiber, carotenoids, antimicrobial activity, yeast and mold counts. The product was found to have high functional value due to the high content of phytochemicals like carotenoid and total phenols. The bread enriched with fresh red bell pepper (23.71% M.C, 0.004% A.C, 5.41% F.C), dry red bell pepper powder (21.81% M.C, 0.006% A.C, 10.48% F.C) and red bell pepper paste (21.81% M.C, 0.005% A.C, 5.91% F.C) has high moisture, ash and fiber content as compared to control bread (19.05% M.C, 0.001% A.C, 3.45% F.C). Product prepared with powder (1.5%) had high phenolic content and antioxidant activity as compared to other breads which incorporated with fresh red bell pepper (20%) and paste (20%). Product (bread) incorporated with paste of red bell pepper has good appearance and bright in color. Fresh bell pepper product had high sensory scores as compared to others. According to these results, the use of bell pepper can enhance nutritional quality as well as the sensory characteristics of bread.

Abstract:

Bread is an ideal vehicle to impart bioactive compounds to the consumers in a convenient manner. This study evaluated bread enriched with Red Sweet Pepper powder (RSP) at 2, 4, 6, 8 and 10% compared to control bread (without RSP). The bread crumbs were assayed for bioactive, physical, nutritional, textural, color and sensory properties. Bread supplemented with RSP improved its color, nutritional and bioactive properties. The low moisture content and increased hardness were observed at higher levels of RSP. Color intensity (expressed as L*, a*, b* values) of bread with 2 and 4% RSP were lower than those of high levels and the same trend was observed for protein, fiber and ash content of bread. Significant (p<0.05) increases were recorded for bioactive compounds such as total phenols (0.145 to 235 mg GAE/g), antioxidant activity (56% to 78%) and flavonoids (0.112 to 0.379 mg/g) as the level of powder increased. Bread enriched with 8% RSP showed improved sensory profile as compared to control, whereas a further increase in RSP decreased the sensory and textural properties. Thus, RSP act as a natural colorant and functional food that enhanced the functional and nutritional properties of bread and can be used to customize bread for specific health needs.

Abstract:

Food and nutrition are the prime source of energy for our body. Food intakes play an important role in body weight. Nutrition is defined as the process in which animal or plant takes in and utilizes to release energy from the body. It is essential for growth and development, health and wellbeing. These are assessed by bodyweight which categorize by body composition analysis. Relationship between food nutrition and body weight includes a discussion of how the body weight can be maintained with a healthy balanced eating habit and lifestyle modification. The factors affecting the eating habits depend on the time, quality and quantity of food. The urge to eat is controlled by gut hormones and brain, mainly hunger hormones and satiety hormones, after a sustained weight loss within two years, the satiety hormones are override by hunger hormones, by a feeling of hunger which tends to have more food is influenced by factors such as food's savory appeal, the body's fat stores and need of energy. For decades, scientists have been researching the role of two hormones called leptin and ghrelin in regulating hunger, food preferences and satiety as signals from the body to the brain and seem to regulate appetite and satiety. Life style correction to manage body weight are dietary plans, physical activity and behavioral therapy, which helps the complete transformation of the individual. Attitude towards the eating, exercise and behavior therapy are essential for a sustained weight reduction. Life style changes leads to obesity, which is a chronic medical condition. Obesity in adulthood leads to diabetes, high blood pressure, cardio vascular disease, gallstones, strokes, risk factor for a number of cancers which is associated with a striking reduction in life expectancy for both men and women so that a healthy lifestyle correction is required. For a healthy life style modification wellness centers are recommended to give guidelines and motivational support to the individual in order to change their attitude, awareness and authenticity towards a healthy living.

Abstract:

The objective of present investigation was to assess the effect of physicochemical, thermal and rheological properties of the eminent Indian rice cultivars (PR-114, PR-121, PR-122, PR-123, PR-124, PR-126 and PR- 127) on their extrusion behavior. Rheological properties such as pasting temperature, peak, hold, breakdown, setback and final viscosities were evaluated using Rapid Visco Analyzer that in turn main set a significant impact over the extrusion behavior of the selected cultivars. Cultivars like PR-122 and PR-124 categorically demonstrated a high water solubility index of 48.52 and 41.86 percent due to the presence of high amylose content i.e., 28.86 and 26.14 percent respectively. A noteworthy variation was observed in the expansion ratio of the resultant extrudates which is correlated with the degree of gelatinization because it is directly dependent on the granule structure destruction. It is one of the most important product responses that play a crucial role in governing the acceptability of the product. Gelatinization temperature showed significant positive correlation with amylose content and pasting temperature. A significant variation was testified in the bulk density of the resultant extrudates. These broadly diversified and anticipated physicochemical, thermal and rheological properties of the Indian cultivars possess significant impact on their extrusion behavior. Their detailed information can establish the foundation for obtaining extruded products with more acceptable and anticipated characteristics.

Abstract:

Studies on deactivation kinetics as well as quantification of temperature dependent macromolecular properties of protein like activity and stability are ineluctable for predicting economic feasibility for industrial applications. L-asparaginase (L-asparagine amidohydrolase, E.C. 3.5.1.1) is an industrially important enzyme which catalyzes the conversion of L-asparagine to L-aspartate and ammonia. This enzyme has been using as a food processing enzyme as it can effectively reduce the level of acrylamide in a range of starchy foods. L-asparaginase also has application in the treatment of acute lymphoblastic leukemia and its clinical action is attributed to the depletion of L-asparagine, since tumor cells are impotent to synthesize this amino acid and are selectively killed by L-asparagine deprivation. This study reports the temperature dependent deactivation kinetics and stability studies of Vibrio cholerae L-asparaginase. Circular dichroism and differential scanning calorimetry studies have been carried out to understand the temperature-dependent conformational changes in the secondary structure of V. cholerae L-asparaginase. Thermal stability studies on V. cholerae L-asparaginase revealed that the protein is stable up to 40 °C, retaining 70-85% residual activity even after 6 hours of incubation. Moreover it possessed very high melting point of 81 °C and high half-life time of 1100 minutes at 37 °C. Protein was found to be less stable at higher temperatures of 45, 50 and 55 °C and residual activity was declined to 1-6 % in 15 minutes. The effect of various thermal additives like glycerol, glycine and trehalose on thermal stability of V. cholerae L-asparaginase was evaluated. Compared to other thermal stabilizers tested, glycine was found to be more effective which resulted in five folds increase in halflife time of enzyme at 50 °C.
