Pengaruh penambahan emulsifier lesitin terhadap kestabilan campuran madu herbal madu minyak habbatussauda dan minyak zaitun telah diteliti Kestabilan campuran madu herbal diuji dengan dengan 4 macam cara yaitu sentrifugasi cycling test uji viskositas dan uji ukuran partikel Hasil uji sentrifugasi pada campuran madu herbal dengan konsentrasi lesitin di bawah 5 massa minyak tidak menunjukkan adanya pemisahan fasa Penambahan lesitin setelah batas tertentu akan meningkatkan viskositas campuran Penambahan lesitin sebesar 5 dari massa total minyak ke dalam campuran dengan konsentrasi minyak 7 5 memberikan viskositas yang minimum 4870 cp Cycling test dilakukan dalam refrigerator 4oC dan oven 40oC selama masing masing 24 jam sebanyak 3 kali Hasil cycling test tidak menunjukkan adanya kristalisasi ataupun pemisahan fasa Analisis PSA Particle Size Analyzer membuktikan bahwa penambahan lesitin menyebabkan pembesaran ukuran partikel Rata rata diameter partikel campuran madu herbal tanpa lesitin sebesar 6 3 mm sedangkan campuran madu herbal dengan lesitin sebanyak 1 dari total minyak adalah sebesar 4 67 mm Dari penelitian ini dapat disimpulkan bahwa penggunaan lesitin sebanyak 1 5 dari total massa minyak konsentrasi 7 5 10 dapat menghasilkan campuran yang stabil ......The influence of adding lecithin emulsifier on the stability of a mixture of herbal honey honey Black Seed oil and olive oil was examined Stability tested herbal honey mixture with 4 kinds of ways namely centrifugation cycling test viscosity test and the test particle size Centrifugation test results in a mixture of herbal honey with lecithin concentrations below 5 oil mass not show phase separation The addition of lecithin after a certain threshold will increase the viscosity of the mixture The addition of 5 lecithin total mass of oil into the mix with the oil concentration of 7 5 gives a minimum viscosity cp 4870 Cycling test performed at 4oC refrigerator and oven 40oC for 24 hours each 3 times Cycling test result does not indicate the availability of crystallization or phase separation Analysis of PSA Particle Size Analyzer showed that the addition of lecithin causes enlargement of the particle size The average particle diameter of herbal honey mixture without lecithin is 6 3 mm while herbal honey with lecithin mixture of 1 of the total oil is at a 4 67 mm From this study it can be concluded that the use of lecithin 1 5 of the total mass of oil concentration from 7 5 to 10 can produce stable mixtures

Dalam penelitian ini dilakukan sintesis polistirena-ko-poli(etil akrilat) dengan metode Atomic Transfer Radical Polymerization (ATRP) untuk mempelajari pengaruh konsentrasi stabilisator dan inisiator terhadap solid content dan viskositas, serta mempelajari pengaruh variasi komposisi monomer terhadap temperatur transisi gelas (Tg). Dari hasil penelitian didapatkan bahwa semakin tinggi konsentrasi stabilisator dan inisiator maka solid content dan viskositas akan semakin tinggi, dan pada variasi komposisi monomer tidak memberikan kecenderungan pada temperatur transisi gelas yang dihasilkan. Terbentuknya polistirena-ko-poli(etil akrilat) ditunjukkan oleh hasil karakterisasi dengan Fourier Transform Infra Red dan Differential Scanning Calorimetry yang terlampir dalam penelitian ini dan memiliki hasil tidak terbentuk homopolimer dari masing-masing monomer.

In this research, the synthesis of polystyrene-co-poly(ethyl acrylate) by the method of Atomic Transfer Radical Polymerization (ATRP) has been done to study the effect of the concentration of stabilizers and initiators on the solid content and viscosity of them. Then, this experiment also studied the effect of variations of monomers composition on the glass transition temperature (Tg) of polystyrene-co-poly(ethyl acrylate). The result showed that the higher concentration of stabilizers and initiators were, the higher the solid content and viscosity of the copolymer was obtained. In addition, the monomers composition did not affect the glass transition temperature of the resulting copolymers. The formation of polystyrene-co-poly(ethyl acrylate) was characterized by Fourier Transform Infra Red and Differential Scanning Calorimetry and the results showed that the formation of two homopolymers did not appeared.

This book aims to disseminate the most current advances in the biotechnological production of D-xylitol and its applications in medical and health care. This book also provides essential information on hemicellulose hydrolysis to recover D-xylose, detoxification of hemicellulose hydrolysates, and improved fermentation methods for increased D-xylitol production. The highlights of strain improvement to increase the D-xylitol titers and downstream recovery of D-xylitol are also discussed in several sections. The current applications of D-xylitol in medical and health care have been used to justify the cost incurred for setting up the demonstration plant for D-xylitol production in the market.

Summary: "Providing chemical engineering undergraduate and graduate students with a basic understanding of how separation of a mixture of molecules, macromolecules or particles is achieved, this textbook is a comprehensive introduction to the engineering science of separation. [bullet] Students learn how to apply their knowledge to determine the separation achieved in a given device or process. [bullet] Real-world examples are taken from biotechnology, chemical, food, petrochemical, pharmaceutical and pollution control industries. [bullet] Worked examples, elementary separator designs and chapter-end problems, giving students a practical understanding of separation. The textbook systematically develops different separation processes by considering the forces causing the separation, and how this separation is influenced by the patterns of bulk flow in the separation device. Readers will be able to take this knowledge and apply it to their own future studies and research in separation and purification. Online resources include solutions to the exercises and guidance for computer simulatio
