An experiment was conducted in Shambat (2012-2013) during the summer and winter seasons to study the stalk-juice quality parameters of 29 exotic and local sweet sorghum varieties as affected by season. The objectives were to provide basic data attributing to syrup and sugar (jaggery) production in the Sudan. The materials were arranged in RCB design. Data were collected on brix, pol (sucrose %), reducing sugars, total sugars, purity and pH. The single and combined analysis of variance revealed highly significant differences among varieties for all traits studied. The variety x season interaction was significant for all traits other than total sugars %, implying the need for considering the variety choice in each season. The results of juice quality parameters were mostly within the range reported in the literature. The exotic materials excelled the local ones in brix, pol%, total sugars% and purity. The exotic varieties: N100, Red-X, Hastings and N110 as well as the local Ankolib selections: AnkNyala and Ank36 were identified as having juice quality traits suitable for syrup production. The exotic varieties: BlueRibbon, KansasCollies and Brawley were identified for sugar (jaggery) production. It was concluded that interaction of variety x season and yield parameters for juice, grain and stover should be considered when determining the choice of the variety. Future research should focus on developing multi-purpose varieties capable for concurrent production of syrup/sugar, grain and stover.

AbstractSugarcane aphids [Melanaphis sacchari (Zehntner)] have become a significant pest of grain, forage, and sweet sorghum [Sorghum bicolor (L.) Moench] in the USA in recent years. However, the effects of sugarcane aphid damage on sweet sorghum juice quality have not been well studied. A three-year (2015–2017) field study was conducted at Tifton, GA to assess planting date effects (April, May, or June planting) and cultivar responses (24 cultivars) to sugarcane aphids in sorghum. Aphid damage ratings were measured in all three years and cumulative aphid days were measured in 2016 and 2017. Cumulative aphid days (ln scale) and damage ratings (relative marginal effect) were correlated in five of the six plantings. Stem juice was collected at maturity from seven plantings for chemical analyses, which included HPLC, fluorescence excitation-emission spectrophotometry with parallel factor analysis (EEM/PARAFAC), and cyclic voltammetry (CV). Aphid damage ratings and cumulative aphid days were negatively correlated with sugar-related traits, particularly brix and total sugars. In four plantings, significant negative correlations (r ≤ −0.493) between trans-aconitic acid concentration and aphid damage were observed. Fluorescence and electrochemical properties related to the presence of polyphenols also showed correlations with aphid damage, particularly in the resistant landrace No. 5 Gambela. These secondary metabolites may play a role in sugarcane aphid resistance or tolerance. Stability analysis revealed that the more tolerant cultivars were able to maintain high concentrations of total sugars and trans-aconitic acid across environments.

Background: Jaggery, a traditional sweetener is produced from the sugarcane juice and its quality mainly depends on cane juice quality. It is specific to check, which sugarcane variety is producing the best jaggery in terms of its quality and recovery. Thus, this study was undertaken to screen five different promising early (CoH 160, Co 89003, Co 0238) and mid season (CoH 119, CoH 167) sugarcane varieties and to prepare and evaluate jaggery qualitatively.Methods: The different sugarcane varieties were harvested at proper maturity, weighed and crushed to extract juice in November, January and March. The juice was analyzed for various physico-chemical parameters viz., total soluble solids (oBrix), purity, pol, juice recovery (%) and commercial cane sugar (%). Good quality jaggery was prepared and evaluated for the sensory characteristics. The jaggery was evaluated quantitatively for physico-chemical parameters (reducing sugars, total sugars, sucrose, net rendement value, hardness and minerals. Result: The jaggery was found to have 8.50-10.70 per cent moisture, 68.82-78.95 per cent sucrose, 7.67-8.83 per cent reducing sugars and 1.45-2.63 per cent ash. The jaggery prepared from Co 89003 had significantly highest sensory scores over jaggery made from all other varieties. Jaggery made from CoH 160 variety was comparable with that of Co89003 variety. The early sugarcane varieties Co 89003 and CoH 160 were found to produce good quality jaggery as compared to mid-late varieties.

Objective: to analyze physicochemical, microbiological and dirt parameters in marketed honeys, consumed by the elderly cared for at Integrated Health Center in Teresina, Piauí, Brazil. Method: the following analyses were performed: color, water activity, humidity, ash, pH, acidity, reducing sugars, total sugars, apparent sucrose and insoluble solids. Contamination indicator bacteria, mesophilic microorganisms, filamentous fungi and yeasts, as well as dirt and foreign matter, performed in the period from April to June 2016. Results: analyses of ash, pH, acidity and insoluble solids were outside current standards. Microbiological analyses did not present significant contamination. Also, analyses of dirt showed insect fragments, foreign matter in almost all the samples. Conclusion: parameters of ash, pH, acidity and insoluble solids, as well as dirt and foreign matter, indicated that the samples were not in accordance with current legislation.

Moringa Oleifera Lam

Moringa oleifera Lam., commonly found tree in sub-Himalayan tracts of India, Pakistan, Bangladesh and Afghanistan has a high nutrition value. The leaves, flowers and immature pods of Moringa are used as a vegetable in many countries. The leaves are highly nutritious and medicinal in nature. They are a rich source of iron, calcium, vitamin A, vitamin C, proteins, and essential amino acids. Hence Moringa leaves can be a good source of protein for the vegetarians and the under-nourished population. Present investigation deals with the study of monthly variation in the nutritional value of Moringa leaves from the month of June 2015 to January 2016. Impact of urban sewage pollution and roadside vehicular pollution on the amount of reducing and total sugars, chlorophylls (a, b and total), proteins, vitamin-C and pH of the leaves, was also studied. Results revealed that the highest amounts of reducing sugars, total sugars, chlorophyll b and total chlorophyll during October 2015 whereas proteins, chlorophyll a, vitamin C and pH were highest during January 2016. Leaf samples collected from all the study sites exhibited minimum amounts of reducing sugars, chlorophylls (a, b and total) and pH during July 2015 whereas total sugars were lowest during December 2015. Proteins and vitamin C values were lowest during August and June 2015 respectively. Sewage and vehicular pollution showed an adverse effect on the nutritional contents of Moringa oleifera leaves. Of the two polluted sites, samples from near the sewage flow showed higher impact.
