Journal ArticleDOI
Influence of emulsion and powder size on the stability of encapsulated d-limonene by spray drying
Apinan Soottitantawat,Fanny Bigeard,Hidefumi Yoshii,Takeshi Furuta,Masaaki Ohkawara,Pekka Linko +5 more
TL;DR: In this article, the microencapsulation of d-limonene by spray drying was investigated with respect to the effects of emulsion droplet size, powder particle size, as well as to the effect of various kinds of matrices (gum arabic, maltodextrin, and modified starch) on its stability.
Journal ArticleDOI
Flavor release from spray-dried maltodextrin/gum arabic or soy matrices as a function of storage relative humidity
Hidefumi Yoshii,Apinan Soottitantawat,Xiang-Dong Liu,Takuroh Atarashi,Takeshi Furuta,Shizuo Aishima,Masaaki Ohgawara,Pekka Linko +7 more
TL;DR: In this article, the microencapsulation of emulsified ethyl butyrate by spray drying and its release from the spray-dried powder was investigated, and the rate of release of the encapsulated butyrates during storage was not only dependent on the relative humidity of storage, but also on the type of the emulsifier.
Journal ArticleDOI
Microencapsulation of l-menthol by spray drying and its release characteristics
Apinan Soottitantawat,Kohei Takayama,Kenji Okamura,Daisuke Muranaka,Hidefumi Yoshii,Takeshi Furuta,Masaaki Ohkawara,Pekka Linko +7 more
TL;DR: In this paper, the microencapsulation of l-menthol was studied by spray drying, using gum arabic (GA) and modified starch (CAPSUL, HI-CAP 100) as capsule materials.
Journal ArticleDOI
Effect of water activity on the release characteristics and oxidative stability of D-limonene encapsulated by spray drying.
Apinan Soottitantawat,Hidefumi Yoshii,Takeshi Furuta,Masaaki Ohgawara,Pirkko Forssell,Ritta Partanen,Kaisa Poutanen,Pekka Linko +7 more
TL;DR: The stability of encapsulated D-limonene, which was prepared by spray drying, was studied in view of the release characteristics and oxidation stability, and the results could be explained by a change in the powder structure, where a glass capsule matrix was changed into rubbery state during storage.
Journal ArticleDOI
Biodegradable products by lipase biocatalysis
TL;DR: The discovery that lipases can also catalyze ester syntheses and transesterification reactions in organic solvent systems has opened up the possibility of enzyme catalyzed production of biodegradable polyesters.
