“…If the search is carried out with a change in the type of reactor to “fluidized bed reactor”, an additional 15 articles will be added to the list. Among these, only 16 articles, specifically related to the food industry, are included in Table 2 [ 29 , 30 , 31 , 32 , 33 , 34 , 35 , 36 , 37 , 38 , 39 , 40 , 41 , 42 , 43 , 44 ]. In this case, there was no restriction on the reactor volume as all the papers refer to preliminary studies, and the reactor dimensions are relatively small, usually in the order of a few centimeters or even millimeters.…”

“…In this case, there was no restriction on the reactor volume as all the papers refer to preliminary studies, and the reactor dimensions are relatively small, usually in the order of a few centimeters or even millimeters. Only five papers describe the use of a fluidized bed reactor [ 33 , 37 , 38 , 39 , 40 ], with the packed-bed configuration being the most common. Not all processes are continuous, as there are specific cases where part of the reaction medium is recirculated [ 37 ] or even the entire reactants are recirculated through the bed using a storage tank as a reservoir, making the operation occur in batch cycles [ 38 , 40 ].…”

Esters are versatile compounds with a wide range of applications in various industries due to their unique properties and pleasant aromas. Conventionally, the manufacture of these compounds has relied on the chemical route. Nevertheless, this technique employs high temperatures and inorganic catalysts, resulting in undesired additional steps to purify the final product by removing solvent residues, which decreases environmental sustainability and energy efficiency. In accordance with the principles of “Green Chemistry” and the search for more environmentally friendly methods, a new alternative, the enzymatic route, has been introduced. This technique uses low temperatures and does not require the use of solvents, resulting in more environmentally friendly final products. Despite the large number of studies published on the biocatalytic synthesis of esters, little attention has been paid to the reactors used for it. Therefore, it is convenient to gather the scattered information regarding the type of reactor employed in these synthesis reactions, considering the industrial field in which the process is carried out. A comparison between the performance of the different reactor configurations will allow us to draw the appropriate conclusions regarding their suitability for each specific industrial application. This review addresses, for the first time, the above aspects, which will undoubtedly help with the correct industrial implementation of these processes.

“…Sedangkan sintesis karbohidrat ester dengan metode enzimatik akan menghasilkan reaksi yang lebih spesifik, dikarenakan sifat khusus enzim. Selain itu, sintesis enzimatik dilakukan dalam kondisi yang tidak membutuhkan energi yang tinggi dan jauh menghasilkan produk yang tidak beracun dibandingkan secara kimia [3]. Kelebihan dari surfaktan ini adalah dapat digunakan pada rentang pH yang luas, biodegradable, lembut dan bersifat noniritasi, baik untuk kulit dan mata, toksisitas rendah dan pembusa yang stabil [10].…”

Carbohydrate ester is one of many needed nonionic surfactant groups and has the potential to be an environmental friendly surfactant. The principal problem in the synthesis of carbohydrate ester is to obtain the optimum conversion of palmitic acid from temperature influence, the amount of biocatalyst and reaction time. The optimization of carbohydrate ester synthesis is carried out on three variables that influence the esterification reaction. Therefore, the esterification process is carried out by reacting directly the palmitic acid and fructose using a Novozyme®435 an immobilized lipase enzyme catalyst with a free variable of reaction temperature of 41,5 oC, 45 oC, 50 oC, 55 oC, 58,4 oC, the amount of biocatalyst is 6,63%, 8%, 10%, 12%, 13,36% mass based palmitic acid also reaction time of 7,6 hours; 24 hours; 48 hours; 72 hours; 88,3 hours and reacted with fixed variable in 500 rpm; 3:1 substrate ratio (fructose:palmitic acid) and solvent amount 10 ml. The mixture is then separated from the catalyst by filtration. The product was analyzed with determination of acid number to obtain conversion percent of fructose ester, determination of Hydrophilic Lipophilic Balance, Fourier Transform Infrared (FTIR) an surface tension determination. The optimum conversion rate obtained is 61,80% at 55 oC of reaction temperature, Novozyme®435 enzyme count is 12% and 72 hours of reaction time. From the result of fructose ester surfactant analysis obtained HLB 10,592 value which showed fructose ester surfactant can be used as emulsifier of oil in water.

“…The number and the length of these acid derived chains, together with the number of hydroxyl groups of the particular sugar determine the hydrophilic-lipophilic balance (HLB) -a unique property of a given molecule of sugar ester. At the same time their chemical structures enable them to form micelles, emulsions, stabilize foams thanks to their surface active properties [2,3]. These features bring practical importance of sugar fatty acids esters (SFAEs), hence they are widely used in the food, cosmetic and pharmaceutical industries (as additives for dairy products, feeds, creams, gels, shampoos, pastes, ointments) [3][4][5][6][7].…”

Sugar esters are bioactive compounds derived from renewable resources. They consist of a sugar moiety with attached non-polar part – usually a fatty acid. These compounds find uses in cosmetic, food and pharmaceutical industries as surfactants due to their physicochemical and antimicrobial activities. In this study we have produced fatty acids for sugar ester synthesis from bacterially derived polyesters, namely polyhydroxyalkanoates (PHAs). We have developed methodology to decorate PHA monomers with a fluorinated moiety. With aid of biocatalysis a series of glucose esters was created with unmodified and modified PHA monomers. All synthesised compounds showed moderate antimicrobial activity.
