Development process of rice analogues by utilising the broken rice (BRF) and broken pigeonpea dhal (BPDF) flours together with water and sodium alginate as binding agent through extrusion was carried out. Two variable viz

A multi-residue method was developed and validated for the simultaneous determination of 39 and 33 chemical pesticides in rice using LC-MS/MS and GC-MS/MS, respectively. The coefficient of determination was 0.994 to 0.999 over the linear concentration range of 0.01 to 0.1 μg mL-1. The LOD and LOQ were in the range of 0.31 to 3.35 and 1.04 to 10.06 μgkg-1, repsectively. The mean recoveries at 0.01, 0.05, and 0.1 mgkg-1 were found within the range 70 to 120% with satisfactory precision (RSD < 15%). Measurement uncertainty (Uexp) values estimated at 0.05 mgkg-1 spiking level were found lower than 20 μgkg-1 for all tested pesticides. A rice and wheat powder check samples under the proficiency test were analyzed using a standardized method, and the Z score recorded within the acceptable range of −2 to +2. The proposed method was applied to analyze the pesticides in real samples collected from the market and quantified the residues. The developed method could be useful for monitoring 72 chemical pesticides in rice matrices and can be adopted for the pesticide monitoring program.

Composition, nutritional value and sensory characteristics of donkey milk of Indian small grey breed was analysed using AOAC and other standard methods. Fresh donkey milk had 90.63% (w.b.) moisture content, 0.76% fat, 1.96% protein, 6.30% lactose, 0.40% ash. Particle size of donkey milk was 355.00 d.nm. The UHPLC analysis ascertained that lysozyme content was more in donkey milk sample. The ICPMS confirmed that Ca, K, Mg, Na, vitamin C and E, glutamic acid, leucine, proline were the most abundant in donkey milk, but Fe, Zn, Vitamin A and B1, methionine shown lower amount. The GC analysis determined that butyric acid, lauric acid was more and lower amount of unsaturated fatty acids were observed in donkey milk sample. Finally, the TPC, yeast and mould count were acceptable and confirmed that donkey milk is microbiologically safe and sensory evaluation studies of donkey milk confirmed that the desired sensory attributes.

An analytical method in pomegranate whole fruits and arils was developed in LC-MS/MS and validated as per SANTE/12682/2019. Samples were extracted following acetonitrile-based modified QuEChERS protocol. The method was linear and the coefficient of determination ranged between 0.998 and 0.999. Through this method, all the pesticides were detected and quantified at 10 µg kg

The effect of three different extraction methods, namely supercritical CO2, soxhlet and solvent methods on the yield, efficiency, physico-chemical properties, nutritional, anti-nutritional composition, antimicrobial and antioxidant activities of moringa (Moringa oleifera Lam.) seed kernel oil was investigated in this study. Oil extraction for SC-CO2 were 37.76 g/100g and 98.43%, observed to be higher than those of soxhlet extraction (29.12 g/100g and 76.29%), and significantly lower than solvent extraction (22.12 g/100g and 57.99%). The physico-chemical composition of the oils showed considerable variation among the extraction methods. The SC-CO2 extracted oil was found to be of superior quality, showing negligible thermal degradation and exhibited significantly (p

Wheat grass powder contains various antioxidant compounds and has excellent antioxidant activity. Wheat grass powder was added at 0, 2.5, 5.0, and 7.5% levels by replacing wheat flour to make muffins namely control, WG2.5, WG5.0, and WG7.5. The viscosity in the muffin batter, hardness, chewiness, protein, total dietary fiber, ash, and total phenolic content of baked muffins increased with increasing wheat grass powder levels. The volume, cohesiveness, springiness, and color (L, a, b values) of samples showed a reverse trend. Sensory testing of WG7.5 showed lower acceptability while WG5.0 had the maximum score (8.4) as compared to other levels.

The aim of this work was to study the influence of processing conditions on spray dried Osmanabadi goat milk powder. The milk solid loads of 35, 40 and 45% and inlet air temperature of 160, 170 and 180 °C were chosen as independent variables to produce the spray dried Osmanabadi goat milk powder. A mixed fruit flavour was added to the concentrated milk to avoid the goaty flavour in the final powder. The mean values of proximate composition of spray dried Osmanabadi goat milk powder viz ., moisture content, fat, protein, carbohydrates, ash and titrarable acidity were 4.08%, 26.85%, 25.48%, 36.99%, 6.60% and 0.14%, respectively. Colour L * , water activity, bulk densities including loose and tapped bulk densities were decreased with increase in inlet air temperature and bulk density increased with increase in concentration. The handling properties i.e. , flowability was “possible” and “fair” according to Hausner ratio (1.24 ± 0.01) and Carr's index (19.48 ± 0.88%) values. The solubility, wetting time and dispersibility of spray dried goat milk powder were significantly affected by the independent factors.
