Determination of phenolic compounds and coumarins in sugar cane spirit aged in different species of wood

The identities and quantities of the phenolic compounds and coumarins in twelve samples of sugar cane spirit aged in Quercus sp., Amburana cearensis, Cariniana legalis, Castanea sativa Mill, Ocotea sp., Cotyledon orbiculata L., and Hymenaea sp. casks were determined. These compounds have a direct influence on the sensory characteristics of aged beverages; some of them are considered to be markers for the aging process. The analysis of phenolic compounds was performed by HPLC. Solid phase extraction (SPE) was also used for the determination of coumarins. The concentrations of the principal compounds extracted varied according to the species of wood. The concentrations of total phenolic compounds ranged from 0.08 for a sample stored in a 4000-L jatobá barrel for a period of six months to 40.9 mg · L−1 for a sample aged in a 50000-L oak barrel for a period of 48 months. The use of the SPE technique removed interfering compounds from the samples, thereby improving the detection of coumarin.

Determination of ethyl carbamate in cachaça produced from copper stills by HPLC

Ethyl carbamate (EC) is a common substance in fermented foods and drinks, and its quantification is important because of its carcinogenic nature and its usually presence in alcoholic beverages. The present work involved the development and validation of an analytical method for the evaluation of EC in cachaça by HPLC-FLD after previous derivatization with xanthydrol. The method presented a mean recovery of 94.88%, an intra-day precision of 4.19% (30.0 μg L−1) and 3.32% (75.0 μg L−1), a coefficient of determination (r2) equal to 0.9985, and limits of detection and quantification equal to 6.39 and 21.32 μg L−1, respectively. The results show that the analytical method is accurate, reproducible and linear over the concentration range from 5.0 to 160 μg of EC per litre. The method was applied to the analysis of EC in cachaça, the analyses being rapid and efficient.

Contamination of cachaca by pahs from storage containers

Cachaça is a distiled beverage obtained from the fermentation of sugar cane syrup that, depending on the production procedures, may be susceptible to contamination by polycyclic aromatic hydrocarbons (PAHs). These compounds present carcinogenic and/or mutagenic properties and offer a risk to human health. Sixteen PAHs were determined in cachaças that had been stored in glass bottles and in polyethylene tank by gas chromatography coupled with mass spectrometry. The quantification of the PAHs utilised an internal standard. The limits of detection and quantification varied from 0.05 to 0.10 μg L−1 and 0.20 to 0.30 μg L−1, respectively. A total PAH concentration of 51.57 μg L−1 was found in the beverages that were stored in the tank, while the concentration in the cachaça stored in glass jugs was 6.07 μg L−1. These results indicate that the polyethylene tank is a source for PAHs in cachaça.

Research on policies and institutions to support small and medium scale enterprise in the Caribbean: Trinidad adn Tobago report

The Government of Trinidad and Tobago continues to provide support to SMEs in order to enhance their international competitiveness. The increasing effects of globalization and the reality of several trade agreements require that local businesses attain and maintain a level of competitiveness which ensures their continued survival and growth. This report examines in detail the policy environment within which these enterprises operate. It also examines the role of the key implementing agencies such as the BDC and NEDCO for government’s policy on the sector and also the role of the respective line ministries. These organizations strive to deliver value added technical, financial and export promotion services to its clients on a subsidised basis. The services offered reflect five key business areas such as financing, training, technical assistance, trade assistance, business re-engineering, project management and export promotion. In the case of the BDC its services target six sectors: food and beverage, metal processing, leisure marine, including yachting, information and communication technology/electronics, printing and packaging and entertainment. These said sectors are identified by the government, on the basis of a study which was done by TIDCO, for the promotion of a cluster development strategy. In the case of NEDCO it targets the following sectors: art and craft, food and beverages, fashion and fashion accessories, culture and ecotourism, bed and breakfast operations, indigenous entertainment and light manufacturing.
