Quality Acceptability, Nutritional Composition and Antioxidant Properties of Carrot-Cucumber Juice

Fresh vegetables (carrot and cucumber) were juiced using a juice extractor. The extracted juice was then divided into five varying proportions: A (100% carrot juice), B (80% carrot, 20% cucumber), C (70% carrot, 30% cucumber), D (50% carrot, 50% cucumber) and E (100% cucumber). The juice blends were then analyzed for proximate, mineral and vitamin compositions. The phytochemical and the antioxidant properties were also determined. The proximate composition result revealed very high moisture (82.03–83.85%), relatively low carbohydrate (5.23–10.57%) and very low crude protein (1.75–4.14%) contents. For the micronutrients, potassium (14.70–32.10 mg/100 mL) and vitamin C (14.48–24.48 mg/100 mL) were more predominant when compared to the other micronutrients that were determined. The pH was mildly acidic (5.90–6.21) and the Brix value ranged between 3.51 and 7%. The antioxidant result indicated that better bioactivity could be obtained from the blends than the individual juices. While there were no statistically significant differences in the sensory properties of the juices, the 100% carrot juice was rated higher in all the attributes evaluated. Therefore, it was concluded that a blend of carrot and cucumber at a 50:50 ratio offered comparable nutritional and better antioxidative quality when compared to other blends.

Effects of pure and mixed substrates of sisal waste, grass (Panicum coloratum) and a combination of the two substrates at 50:50 (w/w) on nutritional composition, minerals and antioxidant potential of sun-dried Pleurotus sapidus 969 were investigated in the present study. To determine the proximate chemical composition and antioxidant properties of the samples, standard analytical procedures were employed. Moisture content, crude protein and crude fibre ranged between 11.09-12.80%, 6.4-6.6% and 18.3-30.5%, respectively. Macro elements Ca, Mg, Na, K, and P were also found in substantial amounts with K being present in an exceedingly higher amount (541.3-657.1 mg/100g) than the other macro minerals. The samples from the three substrates contained antioxidant β-carotene (4.6-6.0 mg/100g), lycopene (4.9-5.1mg/100g), Vitamin C (5.2-5.6 mg/100g), phenols (361.0-859.0 mg of GA/g) and flavanoids (33.5-64.0 mg RE/g).Mushroom harvested from mixed substrates contained better nutritional qualities than the pure substrate, although the phenolic content in mushrooms cultivated on sisal substrate was higher. The results further showed that, all the extracts exhibited scavenging ability and metal chelating activity. The findings showed that Pleurotus sapidus 969 is rich in nutrients, macro minerals as well as natural antioxidant which could be explored for pharmaceutical applications.

Lotus (Nelumbo nucifera) rhizome possessed abundant nutrients such as vitamin C, minerals and antioxidants. The consumption of lotus rhizome is limited in Malaysia due to limited information on its nutritional values. Cooking or heat treatment may cause nutritional changes in the food, however, there is a lack of study on the effect of cooking methods on nutritional contents of lotus rhizome. In this study, the effects of cooking methods (steaming, boiling and deep-frying) on nutritional composition (proximate, vitamin C and minerals) and antioxidant properties (total phenolic content, total flavonoid content, DPPH and ABTS scavenging activity) of lotus rhizome were investigated. Results showed that boiling significantly increased moisture and crude fibre but decreased ash, crude fat and crude protein contents of lotus rhizome. Meanwhile, deep frying significantly reduced moisture and increased ash, crude fat, crude protein, crude fibre and carbohydrate contents of lotus rhizome. Steaming induced no significant changes in moisture, crude protein, crude fat, crude fibre, carbohydrate, vitamin C and mineral (potassium, zinc and copper) contents when compared to the raw lotus rhizome. Boiling significantly reduced the amount of vitamin C while deep frying caused a significant reduction in total phenolic content, total flavonoid content and antioxidant activity for both ABTS and DPPH assays of lotus rhizome. In conclusion, steaming would be the best cooking methods for lotus rhizome while deep frying is not recommended to retain the nutritional composition and antioxidant properties of lotus rhizome.

Research objective. Differentiation of natural focal areas of Western Siberia by integral incidence rates of tick-borne infectious diseases for determination of the strategy and tactics of their comprehensive prevention. Materials and methods. A retrospective analysis of official statistics for the period 2002-2018 for eight sub-federal units in the context of administrative territories was carried out. The criteria of differentiation were determined by means of three evaluation scales, including long-term mean rates of tick-borne encephalitis, tick-borne borreliosis, and Siberian tick-borne typhus. As a scale gradation tool, we used the number of sample elements between the confidence boundaries of the median. The integral assessment was carried out by the sum of points corresponding to the incidence rates for each of the analyzed infections. Results. The areas of low, medium, above average, high and very high risk of tick-borne infectious diseases were determined. Recommendations on the choice of prevention strategy and tactics were given. In areas of very high and high incidence rates, a combination of population-based and individual prevention strategies is preferable while in other areas a combination of high-risk and individual strategies is recommended. Discussion. Epidemiologic zoning should be the basis of a risk-based approach to determining optimal volumes and directions of preventive measures against natural focal infections. It is necessary to improve the means and methods of determining the individual risk of getting infected and developing tick-borne infectious diseases in case of bites, in view of mixed infection of vectors, as well as methods of post-exposure disease prevention (preventive therapy).

PURPOSE: Despite the increasing importance of assessing quality of life (QoL) in patients with advanced cancer, relatively little is known about individual patient's perceptions of the issues contributing to their QoL. The Schedule for the Evaluation of Individual Quality of Life (SEIQoL) and the shorter SEIQoL–Direct Weighting (SEIQoL-DW) assess individualized QoL using a semistructured interview technique. Here we report findings from the first administration of the SEIQoL and SEIQoL-DW to patients with advanced incurable cancer. PATIENTS AND METHODS: QoL was assessed on a single occasion using the SEIQoL and SEIQoL-DW in 80 patients with advanced incurable cancer. RESULTS: All patients were able to complete the SEIQoL-DW, and 78% completed the SEIQoL. Of a possible score of 100, the median QoL global score was as follows: SEIQoL, 61 (range, 24 to 94); SEIQoL-DW, 60.5 (range, 6 to 95). Psychometric data for SEIQoL indicated very high levels of internal consistency (median r = .90) and internal validity (median R2 = 0.88). Patients' judgments of their QoL were unique to the individual. Family concerns were almost universally rated as more important than health, the difference being significant when measured using the SEIQoL-DW (P = .002). CONCLUSION: Patients with advanced incurable cancer were very good judges of their QoL, and many patients rated their QoL as good. Judgments were highly individual, with very high levels of consistency and validity. The primacy given to health in many QoL questionnaires may be questioned in this population. The implications of these findings are discussed with regard to clinical assessment and advance directives.

Multiclass Classification Problems

AbstractUnivariate decision tree induction methods for multiclass classification problems such as CART, C4.5 and ID3 continue to be very popular in the context of machine learning due to their major benefit of being easy to interpret. However, as these trees only consider a single attribute per node, they often get quite large which lowers their explanatory value. Oblique decision tree building algorithms, which divide the feature space by multidimensional hyperplanes, often produce much smaller trees but the individual splits are hard to interpret. Moreover, the effort of finding optimal oblique splits is very high such that heuristics have to be applied to determine local optimal solutions. In this work, we introduce an effective branch and bound procedure to determine global optimal bivariate oblique splits for concave impurity measures. Decision trees based on these bivariate oblique splits remain fairly interpretable due to the restriction to two attributes per split. The resulting trees are significantly smaller and more accurate than their univariate counterparts due to their ability of adapting better to the underlying data and capturing interactions of attribute pairs. Moreover, our evaluation shows that our algorithm even outperforms algorithms based on heuristically obtained multivariate oblique splits despite the fact that we are focusing on two attributes only.

Abstract Drying characteristics of Stevia rebaudiana (Bertoni) leaves using radiation drying, convection drying, sun drying, and shade drying treatments were investigated in a convective type. Results for all treatments indicated that drying took place in the falling rate period. The chroma of the dried samples ranged between 29.66 and 23.85. Convection and shade drying samples were found better in colour and had the highest content of total pigments. The proximate and fibre composition were affected by the drying treatments. Extracts obtained from convection drying and shade drying leaves exhibited higher values of Trolox equivalent antioxidant capacities 416.89-423.64 mM mg−1 and ferric reducing power 85.19-87.97%. These extracts also showed ion chelating capacity 59.05-60.21% for Cu+2 and 55.05-59.11% for Fe+2. The results indicate that it is possible to select the drying treatment to obtain the best nutritional and biological properties. Convection drying and shade drying were the least aggressive treatments and leaf powders obtained by these drying methods could be used as sources of nutrients, fibre, and antioxidant compounds.

Cape Gooseberry

Cape gooseberry (Physalis peruviana L.) is a South American fruit with high nutrient content, pleasant taste and antioxidant properties. However, its consumption in some countries is underеvalued. The aim of this study was to determine the nutritional composition of two genotypes of Cape gooseberry fruit produced in Bulgaria (CG-F and CG-P) and to compare it with imported Colombian fruits (CG-C). The samples were assayed for size, diameter, moisture, ash, titratable acidity, pH, protein, lipid, carbohydrate, natural pigments, and mineral content. Bulgarian genotypes were smaller in size than the imported Colombian fruits. The protein content (2.54-1.88 g/100 g) was relatively higher in the imported variety, compared with the locally produced fruit. Carbohydrate content (10.23-14.13 g/100 g) slightly varied between the genotypes. The sweetness of the fruit was due to the main detected sugars – sucrose, glucose and fructose. CG-F and GC-C genotypes had similar sweetness indices, and fruit taste was evaluated as sweet-sour. Pectin content did not exceed 1.85%; the cellulose content varied between 4.29% and 6.64%. Moreover, all investigated fruit had a low lipid content (below 1.00%). The total chlorophyll and carotenoids levels were the highest in the local genotype CG-P (3.62 and 22.36 µg/g). Potassium was the predominant macro-element in all genotypes; there were numerical differences in the rest of the minerals (Ca, Mg, Fe, Cu, Zn, Mn), while the heavy metals, Pb, Cd and Cr, were generally absent. Cape gooseberry fruit of Bulgarian origin was evaluated as a low-calorie nutrient, compatible with the imported Colombian fruit.

SummaryExperiments were conducted on the seed rates of the components of oat-vetch mixtures combined with varying rates of nitrogen fertilizer in a rainfed area of north-east Portugal in 1982–3 and 1984–5.Forage oats grown alone showed a very high yield response to N and rainfall ranging from 30 to 18·2 t D.M./ha, but had a very low crude protein concentration (37–54 g/kg D.M.) and a poor mineral nutrient composition.The increased use of vetch in the seed mixture had a buffering effect on dry-matter (D.M.) yield but this depended very much on crop N nutrition. For N-deficient conditions vetch inclusion increased the D.M. yield and had a strong positive effect on total forage crude protein (CP) and mineral composition. When crop N nutrition was good, very high D.M. yields (> 12 t D.M./ha) were possible using a high proportion of oats, with vetch making a reduced contribution to the yield and nutritive value of total forage.Seed rates suggested in the literature for Mediterranean conditions are adequate for low N inputs and low available soil N, but not for high D.M. yields which can only be obtained by using a higher proportion of oats and adequate N fertilizer.
