Encapsulation of hop (Humulus lupulus L.) essential oil for controlled release in the non-alcoholic beverage application was written by Su, Xueqian;Xu, Yixiang;Xu, Zhiyuan;Hurley, Ken;Feng, Yiming;Yin, Yun. And the article was included in Food Hydrocolloids in 2023.Product Details of 105-87-3 This article mentions the following:
In order to increase the stability of hop (Humulus lupulus L.) essential oil (HEO) and diversify its application into hot beverages, CAPSUL, modified food starch, was used as the wall material to encapsulate HEO at the mass ratio of 2:1 through spray drying under 180°C. The resultant microcapsules were applied to the non-alc. hop tea for the first time and their release kinetics in this matrix were analyzed by gas chromatog.-mass spectrometry (GC-MS). Results showed that the reconstituted HEO emulsion possessed fine droplet size (3.295μm) and high zeta potential (-22.50 mV). The resultant HEO microcapsules exhibited low moisture content (1.249%), suitable bulk d. (0.2934 g/mL), good swelling capacity (2.235 g/g dry solids), low color difference (6.310), desirable morphol. characteristics, high encapsulation efficiency (92.02-95.45%) and high flavor retention (57.13-71.15%). Each target aroma compound had its specific release behavior and mechanism from HEO microcapsules, among which β-myrcene and Me octanoate showed the highest and lowest cumulative release resp. This might be associated with their different volatilities, polarities, function groups and mol. sizes, or their varying hydrogen-bond formation capability at the entrance of starch helix. Most importantly, HEO microcapsules showed significant aroma increasing and stabilizing effects on the hop tea product during storage. These ideal characteristics of HEO microcapsules demonstrated the great potential of diverse essential oil microcapsules as the promising flavoring agents in a variety of hot beverage matrixes. In the experiment, the researchers used many compounds, for example, (E)-3,7-Dimethylocta-2,6-dien-1-yl acetate (cas: 105-87-3Product Details of 105-87-3).
(E)-3,7-Dimethylocta-2,6-dien-1-yl acetate (cas: 105-87-3) belongs to esters. Esters are widespread in nature and are widely used in industry. In nature, fats are in general triesters derived from glycerol and fatty acids. Esters are responsible for the aroma of many fruits. Esters are more polar than ethers but less polar than alcohols. They participate in hydrogen bonds as hydrogen-bond acceptors, but cannot act as hydrogen-bond donors, unlike their parent alcohols. This ability to participate in hydrogen bonding confers some water-solubility.Product Details of 105-87-3
