Leptadenia pyrotechnica (Khimp) is a small shrub belonging to family Asclepiadaceae found growing in the arid zone of Rajasthan. It has ethnopharmacological importance and known for its stem fibre. Its edible unripe fruits contribute significantly to the food and energy needs of rural populations. These are known as khimpoli and cooked as vegetable. Comparative evaluation of nutritional composition of the pods from different regions of Rajasthan was carried out so as to promote these underutilised fruits. Analysis was carried out using standard AOAC methods. Fruits were found to be rich in ash (5.03 % to 5.57 % ), fat (5.35 % to 6.82 % ), protein (13.28% to 18.56 %), sugar (5.61 % to 6.54 % ), vitamin C (66.62 to 90.1 %) and minerals viz., Cu, Zn, Fe, Mn, Mg, P, K, Ca and Na. Results indicated that khimp pods can be promoted as supplementary food in arid region.

Cordia gharaf is a small bushy tree or a large shrub belonging to family Boraginaceae found growing in the arid and semi-arid tropics. It is mainly important due to its ethnopharmacological and chemotaxonomic properties but also has edible fruits which contribute significantly to the food and energy needs of rural populations. Fruits are sweet and mucilaginous and much relished by children. These are either eaten raw or cooked, often put in porridge and used as a sugar substitute. They are often sold in the local market of Jodhpur, Rajasthan, at about Rs. 80-100/- per kg. Owing to edible and medicinal importance of fruits these were collected and analyzed for their nutritional composition. Morphological data was recorded and ash, protein, sugar, fat, dietary fibre and mineral content were determined by standard AOAC methods. Fruits were found to be rich in protein (11.37-12.85%), sugar (8.14-15.13 %) and minerals viz., Ca 0.27-0.76 mg/100g), Fe (6.7-11.85 mg/100g) and Zn (2.0-2.7 mg/100g), Mg (60.7-86.5 mg/100g), Mn (0.3-1.1 mg/100g) and Cu ( 1.3-1.6 mg/100g). Results indicated that Cordia gharaf fruits can be used as a supplementary food in this region and promotion of these trees can help generate livelihood for the local mass.

The proximate analysis of the fruit sample that homogenously sampled from the wild was taken and quartered to get appreciable weight fit for analysis. Due to it perishable nature the quartered sample for each of the fruit was stored in an air tight container and kept in the refrigerator at a temperature of about 4°C. For the determination of the nutritional composition, parameters which include their proximate, minerals, and vitamin C were quantitatively determined while the anti-nutrient composition were qualitatively and quantitatively analyzed. Compared to ackee’s apple, monkey cola was found to consist of 64.41% moisture content, 1.69% ash, 10.21% crude fibre, 1.25% crude fat, 4.44% crude fibre, 18.06% carbohydrates while ackee’s apple consist of 73.21% moisture, 1.49% ash, 9.38 % crude protein, 13.98% crude fat, 2.08% crude fibre, 0.86% carbohydrates and 4.45% of vitamin C. The mineral analysis for both samples was quantitatively determined using Atomic Absorption spectrophotometer (AAS). The minerals determined for ackee’s apple and monkey cola were magnesium which was 1391.65 ppm, calcium 628.23 ppm, sodium 506.96 ppm, potassium 3976.14 ppm, iron 1.0 ppm, copper 5.00, zinc 4.00, cobalt 3.0 and phosphorus 2616.90 ppm the iron however, was not detected. Ackee’s apple on the other hand, consist of magnesium 498.01 ppm, calcium 478.56 ppm, sodium 398.80 ppm, potassium 4970.18 ppm, copper 2.00, zinc 5.00, cobalt 3.0 and phosphorus 373.84 ppm. The qualitative screening of the anti-nutrients revealed the absence of phenol from both fruit samples while tannins were present only in the monkey cola. The flavonoids, phytic acid and oxalate were quantitatively determined to be 1240 mg, 625 mg and 155 mg for Monkey kola and 640 mg, 340 mg and 65 mg for Ackee’s apple.

Dekopon or Hallabong (Citrus reticulate “Shiranui”) is a hybrid fruit that belongs to the citrus fruits. The scientific and commercial interests in dekopon is due to its nutritional composition. The objective of the study was to verify the influence of ethanol as a pretreatment in reducing drying time as well as maintaining nutritional quality (vitamin C, total phenolic compounds, and antioxidant activity) of dekopon slices. The drying with ethanol at 70 °C promoted the greatest reduction in drying time, but the processed pretreated samples at 50 °C presented the highest level of nutritional quality parameters. Keywords: drying time; vitamin C; phenolic compounds; antioxidant activity

Discussion on the application of fractional derivative algorithm in monitoring organic matter content in field soil is scarce. This study is aimed at improving the accuracy of soil organic matter (SOM) content estimation in arid region, and the undesirable model precision caused by the missing information associated with the larger discrepancy between conventional integer-order, i.e., first order and second order, derivative, and raw spectral data. We utilized fractional derivative (of zeroth order to second order in 0.2-order interval) processing on the field spectral reflectance (R) of the salinized soil sample from Fukang, Xinjiang, and its square root-transformed (R), log-transformed (lgR), inverse-transformed (1/R), and inverse log-transformed (1/lgR) values. The correlation coefficient of each fractional derivative of transformed value with SOM content was calculated. The simulation showed the derivative reflectance value approximates zero. When increasing from zeroth order to first order, the derivative curve gradually aligns to the first-order curve, and the destination alignment was also seen while increasing from first order to second order. The significance test of 0.05 showed initial increase and later decay of bands in the five spectral transformations as the order increases. For specific bands, the derivative algorithm clearly justifies the correlation between soil spectra and organic matter content, and all of the absolute highest correlation coefficient values were obtained at fractional orders. When compared with integer-order derivative, fractional derivative is significantly better in improving correlation, showing overall superiority. The result supports the application of fractional derivative in the hyperspectral remote monitor of SOM in arid zone, which may in turn realize the timely and accurate SOM monitor in arid zone, and provides the basis for ecological restoration.

ABSTRACT: The objective of this research was to evaluate the nutritional composition and bioactive compounds of whole umbu fruit, including pulp, seed and peel, and also of a commercial umbu pulp. Samples of the fractions and of commercial pulp were analyzed for determination of minerals and proximate composition, total phenolic and antioxidant activity. Pulps and peel were also analyzed for vitamin C and carotenoids contents. Commercial pulp presented better nutritional composition than fresh pulp (P<0.05) and the peel presented higher phenolic content and antioxidant activity than seed. Peel also stood out by its vitamin C (79 mg.100 g-1) and total carotenoids (2,751 µg.100 g-1) contents, showing that, as the main barrier of the fruit for its protection, it is a fraction rich in bioactive compounds. The highest dietary fiber and iron contents were observed in umbu seed (P<0.05). Therefore, umbu by-products may be ingredients proper for development of food richer in nutrients and bioactive compounds.

To improve the dietary offering in schools, the French authorities published recommendations on nutrition in 1999, which were then revised in 2007. The aim of the present study was to assess the nutritional offering in secondary school meals and the extent to which the recommendations promote balanced nutritional offerings. In 2005, a national survey was conducted on a representative sample of secondary schools, either administrated by the Ministry of Education (ES) or the Ministry of Agriculture (AS). Information on school-catering organisation and twenty consecutive meals was collected from each of the 707 secondary schools surveyed. Nutritional composition was estimated according to the French food composition database. Univariate and multivariate analyses were used to investigate the impact of food-group frequency guidelines (FFG) on nutritional offering. It was found that 15 and 26 % of ES and AS schools, respectively, had high compliance with the FFG, at lunch. Macronutrient content was unbalanced in ES school lunches in which 42·8 % lipids, 21·5 % proteins and 35·7 % carbohydrates contributed to the energy. Nevertheless, proper offerings in Fe, Ca and vitamin C content were observed. In addition, a lower offering in lipids and a higher offering in proteins, Ca, vitamin C and Fe were found when the FFG were applied (P < 0·001). Similar results were found for AS schools. This paper confirms the effectiveness of FFG in providing nutritionally balanced school meals. However, others measures such as nutrition promotion and actions to improve children's food habits have to be introduced to make the recommendations more effective and easier to understand.

ABSTRACTBatch adsorption experiments with Cs-137 and Co-60 were undertaken using representative samples of geologic materials from the arid region that has been selected for an Australian low-level waste repository. The results indicate that the pH is the main factor affecting the adsorption of Co-60 but has little influence on the sorption of Cs-137. The ionic strength affects Cs sorption, with a decrease in Kd associated with higher ionic strength. Selective sorption sites on mica and illite control uptake of trace Cs, whereas the high total site availability of smectite is significant when the total Cs is higher (1 mmol/L). The effects of mineralogy on Cs sorption which were observed for these complex materials confirmed previous results reported for pure minerals.
