“…Coded variables Real variables Residue Distillate evaporator temperature and feed flow rate were the ones that had greatest effect on the response variable in the short path evaporation process [18,19]. The results obtained in this work confirm this.…”

“…(8), the F 3,15 calculated value (3.35) is very close to F 3,15 tabulated value (3.29). If the F calculated is at least three times higher than F tabulated this is an indication that the model represents well experimental data [18]. In this case, F calculated is 1.02 times higher than F tabulated and only 40.1% of the variation is explained by the model, therefore, the linear model (Eq.…”

“…1 [20]. From tests carried out, it was realized that for pressures lower than 1.33 kPa a considerable amount of volatile material moved toward the trap, hindering the equipment operation at this condition, because the separated material in the trap returned to the evaporator [18]. In order to allow the use of lower pressures, in this work an external condenser was attached to the equipment.…”

“…Hybrid short path evaporation [17][18][19] is an alternative separation process with potential for the recovery and concentration of thermally unstable molecules such as lactic acid. It has been recognized as a promising technology mainly because of its low evaporation temperature and short residence time, which minimize problems with thermal decomposition [20].…”

“…Ordinarily, these constituent plant essential oils occur as liquid at room temperature and are easily transformed from a liquid to gaseous state at room or slightly higher temperature without undergoing decomposition. Methyl chavicol, a predominant essential oil in basil, comprising upto 75% of its composition and also known to be temperature sensitive and tovaporize easily at temperatures above 28 • C [44], has been found to attract various insect pests including whitefly, thus disrupting their feeding on target crops such as tomatoes [43]. Agronet covers have, on the other hand, been reported to increase air temperature by 15% to 20% compared with open field treatments [15,45] which could have promoted the transformation of methyl chavicol and other volatiles from liquid to gaseous state in the current study.…”

Synergistic Effects of Agronet Covers and Companion Cropping on Reducing Whitefly Infestation and Improving Yield of Open Field-Grown Tomatoes

et al. 2016

Tomatoes (Lycopersicon esculentum Mill) are one of the biggest vegetable crops in the world, supplying a wide range of vitamins, minerals and fibre in human diets. In the tropics, tomatoes are predominantly grown under sub-optimal conditions by subsistence farmers, with exposure to biotic and abiotic stresses in the open field. Whitefly (Bemisia tabaci Gennadius) is one of the major pests of the tomato, potentially causing up to 100% yield loss. To control whitefly, most growers indiscriminately use synthetic insecticides which negatively impact the environment, humans, and other natural pest management systems, while also increasing cost of production. This study sought to investigate the effectiveness of agronet covers and companion planting with aromatic basil (Ocimum basilicum L.) as an alternative management strategy for whitefly in tomatoes and to evaluate the use of these treatments ontomato growth and yield. Two trials were conducted at the Horticulture Research and Training Field, Egerton University, Njoro, Kenya. Treatments comprised a combination of two factors, (1) growing environment (agronet and no agronet) and (2) companion planting with a row of basil surrounding tomato plants, a row of basil in between adjacent rows of tomato, no companion planting. Agronet covers and companion cropping with a row of basil planted between adjacent tomato rows significantly lowered B. tabaci infestation in tomatoes by 68.7%. Better tomato yields were also recorded in treatments where the two treatments were used in combination. Higher yield (13.75 t/ha) was obtained from tomatoes grown under agronet cover with a basil row planted in between adjacent rows of the tomato crop compared to 5.9 t/ha in the control. Non-marketable yield was also lowered to5.9 t/ha compared to 9.8 t/ha in the control following the use of the two treatments in combination. The results of this study demonstrate the potential viability of using companion cropping and agronet covers in integrated management of B. tabaci and improvement of tomato yield.

Molecular distillation of copaiba oleoresin—A clean process for diterpenes enrichment

et al. 2022

Copaiba oleoresin has sesquiterpenes and diterpenes with significant medicinal properties, including being antimicrobial, antiparasitic, and wound healing, among others. Thus, the objective of this work was to study the diterpene enrichment of the copaiba oleoresin from Copaifera officinalis via molecular distillation. Evaporator temperature (EVT) and feed flow rate (Q) were evaluated using an experimental design (2 2 with central point) considering the ratio of distillate and residue streams (DTR) as the response to optimize the residue recovery. EVT and Q were the main effects for diterpenes recovery, with the best experimental condition at 100 C (EVT) and 15 ml/min (Q) under 0.001 mbar, of which the residue stream had a diterpenes content of 99.25%. With the molecular distillation process, it was possible to add value to the copaiba streams, separating and purifying diterpenes with applicability in the biomedical and pharmaceutical industries since no solvent is used in this process (clean).
