Before And After

Le nectar de canne à sucre (Saccharum officinarum L.) est utilisé au Gabon non seulement pour la fabrication du sucre industriel, mais également pour la synthèse traditionnelle de vins locaux appelés ‘‘Musungu’’ ou ‘‘Malamba’’. Ces synthèses alcooliques nécessitent l’emploi de nombreux adjuvants dont le rôle exact reste mal défini. Le présent travail a été initié pour étudier l’un d’eux, le bois amer (Garcinia kola) utilisé dans diverses synthèses alcooliques. La méthodologie a consisté à analyser l’évolution de certaines qualités physicochimiques et biochimiques de 1 l des nectars de canne à sucre seuls (témoin), associés à la lie d’anciens vins de canne (Li), au bois amer (Gk) ou à ces 2 amendements (LG), avant et après 4 semaines de fermentation. Les résultats obtenus ont révélé la baisse de l’acidité, de la densité et des sucres totaux dans tous les traitements essais, contrairement aux témoins, après les 28 jours d’incubation. Tous les traitements (essais et témoins) ont en revanche produit des alcools de fortes teneurs comprises entre 7,4 °GL et 9,9 °GL. Mais les vins des traitements témoins quoique très alcoolisés ont tous été jugés aigres et de très mauvaise qualité gustative. Le bois amer ne paraît donc pas intervenir dans les processus de fermentation alcoolique, mais dans la constitution des qualités organoleptiques, en empêchant la prolifération des germes lactiques. Ainsi, dans la perspective d’optimiser la qualité du vin, identifier les germes participants à la fermentation du nectar de canne, sous l’influence de Garcia kola semble être nécessaire.Mots clés : Nectar, Levures, Adjuvants, Alcool, Qualité organoleptique. English Title: Effect of Garcinia kola (Clusiaceae) in the fermentation processes of sugar cane wine (<i>Saccharum officinarum</i> ; Poaceae) in Gabon Sugarcane nectar (Saccharum officinarum L.) is used in Gabon not only for the production of industrial sugar, but also for the traditional synthesis of local wines called ''Musungu'' or ''Malamba''. These alcoholic syntheses require the use of many adjuvants whose exact role remains poorly defined. The present work was undertaken to study one of them, the bitter wood (Garcinia kola) used in various alcoholic syntheses. The methodology consisted of analyzing the evolution of certain of physicochemical and biochemical qualities of 1 l of sugar cane nectars alone (control), associated with the lees of old cane wines (Li), bitter wood (Gk) or 2 amendments (LG), before and after 4 weeks of fermentation. The results obtained revealed the decrease of the acidity, the density and the total sugars in all the treatments tests, contrary to the controls, after the 28 days of incubation. On the other hand, all the treatments (tests and controls) produced alcohols with high contents of between 7.4 °GL and 9.9 °GL. But the wines of the control treatments, although very alcoholic, have all been judged as sour and of very poor taste quality. Bitter wood therefore does not appear to be involved in the processes of alcoholic fermentation, but in the constitution of organoleptic qualities, by preventing the proliferation of lactic acid bacteria. Thus, in order to optimize the quality of the wine, identifying the germs involved in the fermentation of cane nectar, under the influence of Garcia kola seems to be necessary.Keywords: Nectar, Yeasts, Additive, Alcohol, Organoleptic quality.

The mechanized harvest of sugar cane (Saccharum officinarum L.) in Brazil is an irreversible trend and it comes with a great concern about the quality of the cane delivered to the industry. A key component to quality is the billet length which affects the processing of raw material, cane deterioration, invisible losses and load density of transport vehicles. Thus, due to the importance of the billet standard in quality and cost of raw material, this study aimed to evaluate if the mechanized harvesting of sugar cane can supply the quality requirements for the crushing process, regarding the billet length. A plot with burnt sugar cane (3.2 ha) and another one with green sugar cane (8.0 ha) were selected to be harvested by two (2) self-propelled sugar cane harvesters. For each harvested 0.4 ha a sample from each infield wagon was collected. The sample was composed by ten billets. The variability in burnt sugar cane was higher than in green sugar cane, and both harvesters did not present the capacity of keeping the billets with similar lengths when operating either in burnt or green conditions.

Summary The aim of the study was to determine the effect of storage conditions on the quality and health-promoting components of broccoli. Broccoli heads cv. Marathon F1 were stored at 0°C for 100 days in controlled atmospheres containing: 1) 15% CO2 - 3% O2, 2) 10% CO2 - 3% O2, 3) 8% CO2 - 1% O2, 4) 5% CO2 - 3% O2. In the control treatment, broccoli heads were stored in normal atmosphere in crates lined with PE film. Before and after storage, chemical analyses were performed for the content of ascorbic acid, total sugars and glucosinolates - sulforaphane and indole-3-carbinol. Additionally, after storage the quality of broccoli heads was assessed visually on a 1-10 point scale, and the percentage of marketable heads was determined. The total content of sulforaphane and indole-3-carbinol in fresh broccoli was lower in comparison with stored broccoli. The sulforaphane content in fresh broccoli was about twice as high as that of indole-3-carbinol. Storage in an atmosphere consisting of 5% CO2 - 3% O2 was more favourable in comparison with the other gas concentrations in terms of glucosinolate content. A decrease in the content of ascorbic acid and total sugars during storage was noted in all the treatments. The highest loss of these components occurred in broccoli stored in an atmosphere consisting of 15% CO2 and 3% O2. Broccoli heads stored in normal atmosphere completely lost their market quality due to decay, but the quality of broccoli kept in CA was satisfactory.

The Impact

Zakat is one of the five pillars of Islam which has a function of faith, social and economic functions. Muslims who can pay zakat are required to give at least 2.5 per cent of their wealth. The problem of poverty prevalent in disadvantaged regions because of the difficulty of access to information and communication led to a gap that is so high in wealth and resources. The instrument of zakat provides a paradigm in the achievement of equitable wealth distribution and healthy circulation. Zakat potentially offers a better life and improves the quality of human being. There is a human quality improvement not only in economic terms but also in spiritual terms such as improving religiousity. This study aims to examine the role of zakat to alleviate humanitarian issues in disadvantaged regions such as Sijunjung, one of zakat beneficiaries and impoverished areas in Indonesia. The researcher attempted a Cibest method to capture the impact of zakat beneficiaries before and after becoming a member of Zakat Community Development (ZCD) Program in material and spiritual value. The overall analysis shows that zakat has a positive impact on disadvantaged regions development and enhance the quality of life of the community. There is an improvement in the average of mustahik household incomes after becoming a member of ZCD Program. Cibest model demonstrates that material, spiritual, and absolute poverty index decreased by 10, 5, and 6 per cent. Meanwhile, the welfare index is increased by 21 per cent. These findings have significant implications for developing the quality of life in disadvantaged regions in Sijunjung. Therefore, zakat is one of the instruments to change the status of disadvantaged areas to be equivalent to other areas.

Introduction: There is a decline in male fertility thus new treatments are needed. Aims: To test the efficacy of a new dietary supplement developed in the USA and registered as a curing drug in Hungary (OGYI). Methods: In a clinical trial 100 men with low sperm quality (spermium count 5–20 M/ml, good motility 10–40%, and adverse shape 30–50%) were examined. Results: Sperm parameters were measured before and after a 3-month treatment and after another 3-month without treatment. This dietary supplement statistically and clinically significantly improved sperm count and motility. In 74 cases this dietary supplement demonstrated a beneficial effect on sperm quality (more than 10% increase in sperm count, or quality of motility, or shape); in 16 cases the improvement exceeded 30%. No adverse effect could be accounted for this treatment. Conclusions: This new dietary supplement may contribute to the treatment of male infertility. Orv. Hetil., 2012, 153, 1787–1792.
