(Miyazawa et al. 1995; Endo et al. 1997, 1999; Larsen 2002; Taira et al. 2006). The
difficulties to purify them and the low yields prevented their study until then. Using
specific enzymes and/or particular experimental conditions, some works also
reported the existence of cyclodextrins of over 100 glucose units (Terada et al. 1997;
Koizumi et al. 1999; Qi et al. 2004). Larsen (2002) published the first interesting
review on large cyclodextrins.
1.4.5 First Comprehensive Reviews on Cyclodextrins
From a fundamental point of view, an abundant scientific literature has built up
since the 1970s. Indeed, a large number of generalist reviews, book chapters and
books, and articles and patents have been published on practically all the aspects of
cyclodextrins. Crini et al. (2018) recently reported that in the periods 1961–1985
(~24 years), 1986–2000 (~14 years), and 2001–2015 (~14 years), 2654, 18,856, and
42,284 cyclodextrin-related publications have been published, respectively, so many
that it would not be feasible to cite them all. For this, readers should refer to the
library database “Cyclodextrin News” from CycloLab Ltd. (Hungary) which is a
periodical collecting all the cyclodextrin works, i.e., articles, reviews, proceedings,
patents, conferences, and lectures, through different disciplines, i.e., chemistry,
biology, health science, agriculture, nanotechnology, etc. This database is searchable until 2018, when it was turned into a blog and stopped collecting literature.
Table 9 shows the first comprehensive reviews and book chapters on cyclodextrins
during the period 1957–1998.
As already stated, the very first comprehensive review on cyclodextrins was published by French in 1957 (French 1957a). French’s state of the art was continued a
few years later by Kainuma (1984) and Clarke et al. (1988). Research on the action
of Bacillus macerans on starch before 1980 was comprehensively reviewed by
Kainuma. Clarke et al. discussed topics on detection, thermodynamics, and kinetics
of complex formation from a literature survey of 182 previous papers. In 1980,
Saenger published the very first review of industrial applications of cyclodextrins
(Saenger 1980). In a very well-cited review published in the journal Chemical
Reviews, Szejtli wrote: “Cyclodextrins can be consumed by humans as ingredients
of drugs, foods, or cosmetics” (Szejtli 1998). In this review, Szejtli, pursuing the
history of cyclodextrins written by French, divided the chemical and industrial
developments of cyclodextrins into three stages, the discovery period from 1891 to
1935, the exploratory period in 1935–1970, and the utilization period from 1970 to
the present day. The history was then updated later by Loftsson and Duchêne (2007)
and by Crini (2014). Other fundamental reviews published in the period 1970–1990
are reported in Table 1.2.
