Summary of the impact
Yield of valuable biomass fibre components and their utilization in the
food industry has been maximised by novel, cost-effective and
environment-friendly plant fibre extraction methods developed by BEAA.
Specifically, application of these methods enabled patenting and
commercialisation of oat fibre extraction by the Swedish company BioVelop,
directly resulting in commercial impact through international sales of
five nutritional products released since 2010. The most successful of
these is produced at a quantity of 180,000 kg, or € 600,000 per year. In
May 2013, world-leading food-additive giant Tate & Lyle took over
BioVelop, securing the success and lasting commercial impact of the BEAA
technology.
Underpinning research
Researchers in BEAA undertook the first systematic studies in the
fractionation of lignocellulosic and starch-containing biomass such as
cereal residues and abaca [3.1, 3.2, 3.3]. The initial focus of this work
was the characterisation and fractional extraction of plant lignins and
polysaccharides, in order to study the components in detail and isolate
those relevant for industrial applications. Prior to this research, this
biomass was insufficiently characterised to enable full exploitation of
the potential benefits as an industrial feedstock and/or human and animal
feed. In particular BEAA researchers mapped out and underpinned the need
to combine specific dry and wet techniques in preparing biomass for
wet-fractionation, leading to isolation of various cell wall, extractive
and matrix components which was achieved in subsequent research for wheat
[3.4] and demonstrated the generality of these methods amongst crops,
including for abaca fibre [3.5].
The research was led by BEAA in the BioComposites Centre by Dr Mark
Lawther (1986-1996) with research scientists Dr R.C. Sun (1996-2007) and
Dr J.M. Fang (1999-2005) and Director Dr A.J. Bolton (1989-1999). Prof
W.B. Banks (1977-1997) in the School of Agricultural and Forest Sciences
co-initiated the research programme with Lawther in the period up to 1997.
In the period 1993-2003, BEAA researchers generated over 80 papers in this
field of work.
The separation, isolation and characterisation techniques developed,
which span enzymatic, chemical and physical methods, were combined in
novel ways that led to maximisation of yields of selected components of
target biomass [3.6]. Through this work, the BEAA research demonstrated
for the first time the potential of biomass such as wheat straw as a raw
material for new markets, through replacement of non-UK or
environmentally-damaging materials with chemical fractions derived from
agricultural biomass. Because of this innovative approach, BEAA
methodology has made valuable plant products, previously inaccessible due
to their high cost or complex and environmentally unfriendly means of
extraction, accessible for food, feed and other industry and an attractive
and affordable alternative for synthetic or semi-synthetic alternatives.
The research was supported by a number of grants from MAFF (subsequently
DEFRA) [3.7, 3.8] and also led to patents which were central to the
development of a number of products [3.9, 3.10].
The research was utilised 2001-2009 by Prof. Mark Lawther with the
company BioVelop A/S (which became BioVelop International AB in 2005), as
the underpinning basis to further develop (and up-scale) sequential
enzymatic and physical processes for the wet-fractionation of cereal
(wheat, oat, barley and rye) brans into fibre (lignocellulose), soluble
fibre (hemicellulose), protein and oil, starch dextrin and oligosaccharide
(low molecular weight hemicellulosic) fractions. These are effectively new
ingredients which have substantial value in the food and personal care
sectors and were commercially released from 2010.
In addition to commercial impact for Biovelop, the BEAA research was also
instrumental in demonstrating the potential of plant biomass to replace
fossil fuel derived products and played important contributions in the
funding of new commercially focused projects such as the £10M investment
by the Welsh European Funding Office in the BEACON Biorefining Centre of
Excellence involving BEAA scientists [3.11].

Details of the impact
BEAA research by Lawther formed the basis for a series of patents on the
fractionation of oats, which were central to the development of a number
of BioVelop products and responsible for its large commercial success.
BioVelop specializes in the development and scaling-up of cornerstone
technologies relating to the chemical-free extraction of functional
ingredients from cereal grains and brans. Specifically, BioVelop produces
five oat fibre derived products (PromOatTM, released 2010;
AvenaCareTM, released 2011; PrOAteinTM, released
2012; Oat insoluble fibre and Oat Maltodextrin, released 2013) as a direct
impact of BEAA research [5.1].
PromOat is a betaglucan (hemicellulose) soluble fibre-rich ingredient
sold as a nutraceutical for its beneficial effects on maintaining healthy
cholesterol levels. It has a number of allowed health claims, including
those which have been approved by the European Food Safety Authority, the
Food and Drug Administration and Health Canada, for lowering cholesterol
and reducing post- prandial glycaemic response. Because of these health
benefits and its binding and emulsifying properties, PromOat is a very
attractive additive for many food products, ranging from low fat sauces
and dressings, to yoghurts, baked goods, meat products and ready meals.
Thereby, BEAA research not only provides commercial benefits to BioVelop,
but additional health benefits to consumers of a range of food products
[5.1].
PromOat was released on the market in 2010 and by 2012 a biorefinery had
been built for the commercialisation and upscaling of production for
BioVelop's patented oat products. PromOat retails for at least €15 per kg
and with a cost for the raw ingredients of only €0.20, provides a high
commercial benefit to Biovelop. Currently, the entire production capacity
of the refinery is used and produces 180 tonnes of PromOat™ per year with
an annual value of €600,000 [5.2]. In recognition of the importance of
this technology and its application in the food sector, PromOat was
awarded Best Natural Ingredient for Functional Drinks at the Beverage
Innovation awards in 2011 [5.3].
PrOAtein, a protein and oil rich ingredient, and Oat insoluble fibre,
have been sold successfully and increasingly since 2012 and 2013
respectively. Oat Maltodextrin was made ready for market in July 2013
[5.2]. Avenacare™ is BioVelop's first personal care product. This
hypoallergenic liquid form of oat betaglucan, was commercially released in
2011 and is incorporated into a wide variety of skin care, hair care,
personal care and baby care products to deliver the well-recognized and
scientifically-substantiated benefits of oats. Its soothing, revitalising
and strengthening properties have made this a highly successful product
selling at €20 per litre [5.4].
The commercial impact of BEAA research for the commercialisation of
fractionated biomass is further reflected in the success of Biovelop on
the international market. In May 2013, Tate & Lyle, one of the world's
leading providers of specialty food ingredients and solutions, acquired
Biovelop, to expand its production of oat betaglucan as PromOat and
AvenaCare [5.5]. As a consequence of this takeover, the production
capacity of PromOat is being expanded to be more than tripled during the
last 12-18 months [5.2]. As the patents are worldwide and held until at
least 2022, continued success of the sales of these products derived from
the BEAA technology is near guaranteed.
This research also demonstrated the potential of plant biomass to replace
fossil fuel derived products and provided important background for the
funding of new commercially focused projects such as the £10M investment
by the Welsh European Funding Office in the BEACON Biorefining Centre of
Excellence involving BEAA scientists (Iain Donnison, Rob Elias, Joe
Gallagher, Adam Charlton, Ana Winters) with commercial partners and
investment. BEACON provides a mechanism by which academia and businesses
can collaborate and so far it has assisted 45 enterprises, entered
collaborative R&D projects with 14 companies and induced investment of
£3.6M. The focus of BEACON is therefore on the translation of academic
research to create new products and processes. For example within BEACON
oat phenolics (avenanthramides) are being profiled from BEAA bred oat
varieties for use as active ingredients in skin care products, and xylose
is being recovered from oat hulls and converting to xylitol. The EU
Climate-KIC project "ADMIT BioSuccinovate" is developing the process for
conversion of xylose to xylitol. The €13M project led by David Bryant in
BEAA involves the fractionation of cereal straw with the primary objective
of determining sustainable and economic commercial grade bio-succinate
production from next generation C6 sugars. The work has therefore gone
beyond the impact with BioVelop to create a lasting legacy and a culture
of industry relevant research.
