    A year ago, the newly launched network on encapsulation in South-East Asia (NESEA; www.umr-pam.fr/relation-internationale/encapsulation.html) organised its first event with support from the Agency of French Speaking Universities (AUF). This was a Training School of Encapsulation organised by the Bioencapsulation Research Group, AgroSup Dijon and Nha Trang University (Waché, Anal, Chan, Heng, Ngo, In, et al., 2014) (http://bioencapsulation.net/2014_Nha_Trang/). This year, the network met again in early June 2015 with the support of AUF to discuss on the potential application of encapsulation in food and feed matters especially on applications related to aquaculture.


    The network on encapsulation in South-East Asia (NESEA).

    The origin of NESEA is from the Tropical Bioresources & Biotechnology Laboratory ( http://www.umr-pam.fr/relation-internationale/tropical-bioresources-biotechnology.html). This laboratory is an international joint laboratory among Hanoi University of Science & Technology in Vietnam, the University of Bourgogne Franche-Comté and AgroSup Dijon in France. This laboratory is active in food research with main activities on traditional fermented foods (safety, quality, process and as a source of strains and ideas for new fermented food) and on tropical plant bioactive compounds (Cao-Hoang, Chu-Ky, Ho Phu, Husson, Le Thanh, Le-Thanh, et al., 2013). It is particularly involved in Asian programmes to decrease the use of antibiotics in animal feed and human food. Initially, projects were limited to the three founding universities but with this meeting, the involvement level has moved on to a network of laboratories working on food technology and biotechnology in South-East Asia, thus initiating network projects on food safety, quality, microbial process and biotechnological production of active compounds. Among the several activities discussed, plans were initiated at developing encapsulation systems that are appropriate for protecting and targeting actives to be delivered, particularly, for aquaculture. To stimulate research and application in this field, NESEA was created with goals of manpower training, collaboration in research and sharing of technological know-how through the development of collaborative projects between academic laboratories and with the private sector.
    Nha Trang NESEA meeting and objectives

    The International Workshop “Encapsulation technology applied in food, nutrition, aquaculture and breeding”, funded by AUF was organized on June 9-10 2015 by NESEA in Nha Trang University. The aims of this workshop were to provide an opportunity to share knowledge and experience in encapsulation techniques, develop future applications in the aquaculture sector in South-East Asia and set-up linkages and cooperation among scientists and experts through interdisciplinary projects.
    Representatives and experts from various institutions in South-East Asia and Europe have participated in this workshop and the institutions include the Institute of Technology of Cambodia (ITC-Cambodia), AgroSup Dijon (ASD-France), Monash University (Malaysia), the National University of Singapore (NUS-Singapore), the Asian Institute of Technology (AIT-Thailand), Nha Trang University (NTU), the Hanoi University of Science and Technology (HUST), the Vietnam Academy of Science and Technology (VAST) and the Vietnam National University of Agriculture (VNUA) (Vietnam). Nine presentations were followed by active discussions on the encapsulation technologies applied in food, nutrition and aquaculture. This workshop also presented excellent opportunities for exchanges among those present and the sharing of up-to-date knowledge as well as in establishing of future collaborations among the participants.

    NTU, a university active both in aquaculture and in encapsulation, hosted the present workshop cum meeting which was aimed at presenting research fields of the members of the network. Following the larger aim of the supporting agency (AUF), the goal was also to initiate collaborative projects in the South-East Asian region. Taking into account the acuteness of the food safety and supply problems in the region (food safety is in the strategic axes of development of Asean for its present integration stage) and especially the need for antibiotic substitution together with the huge development of Asian aquaculture, the meeting topics were focused on the contribution of encapsulation in food safety and particularly in aquaculture.
    The first day of the meeting was dedicated to scientific and technology contributions. After a presentation on research in the NeoCapsule group of NTU by Ta Thi Minh Ngoc, the biodiversity exploration in the Tropical Bioresource & Biotechnology projects was explained by Chu-Ky Son from Hanoi University of Science and Technology and the actions and objectives of NESEA were shown by Yves Waché from AgroSup Dijon. Chan Eng Seng from Monash University in Malaysia presented an inexpensive way to improve productivity of monodisperse bead production and Paul Heng from the National University of Singapore presented technologies using calcium alginate for coating and encapsulation. Encapsulation of microbial activity was also a centre of attention with the presentation of Anil Kumar Anal from the Asian Institute of Technology in Thailand which dealt with living cells for health purpose and the one given by Phi Quyet Tien from the Vietnam Academy of Science and Technology about enzyme nano-encapsulation. Eventually, the link with aquaculture was made by Ngo Dang Nghia (NTU) and Nguyen Ngoc Tuan from Vietnam National University of Agriculture. The second day focused on the building of collaborative projects and it included a presentation on the potential funding programmes. All members have agreed to define a specific topic within the network project which focuses on Delivery systems for bioactive compounds for aquaculture and animal feed for the future collaboration.

    Perspective of the network.

    After this meeting, the next year should be a year of sustainable development for the network, with events in several Asean countries. Specialised workshops are planned in Singapore, Thailand and Vietnam such as AFSEA2015 (Animal Feeding in South East Asia: Challenges and Prospects) which will be held in November 2015 in Hanoi, Vietnam but the main and important event will be the first BRG-Bioencapsulation Symposium in Asia. The symposium will take place in Malaysia in 2016 and it will be co-organised by BRG (Denis Poncelet) and Monash University Malaysia (Eng-Seng Chan). Further details of the symposium will be made available on the website of the Bioencapsulation Research Group (www.bioencapsulation.net).
    In addition to scientific meetings, at the initiative of ES Chan, Monash University is initiating a short-term attachment programme to promote research collaboration among the researchers in the ASEAN countries, particularly, the early career researchers who are working in the field of 'encapsulation or coating'.
    In relation with this event, some of the partners of NESEA are also involved in a capacity building Erasmus+ European programme called Universities as key partners for the new challenges regarding food safety & quality in ASEAN which has just been selected (https://eacea.ec.europa.eu/sites/eacea-site/files/eplus-cbhe-selection-results-by-region.pdf).
    Acknowledgment
    This workshop was funded by the Agency of French Speaking Universities (Agence Universitaire de la Francophonie/AUF) through the Pre-project for Interuniversity Scientific Cooperation (PCSI) “Creation of a network on bioencapsulation in South-East Asia” funded by AUF during 2013-2015 period.

  • Conférence "Small Angle X-Ray and Neutron Scattering..."

    Le 1/10/15 à 11 h (Salle Brillat Savarin – bât Epicure d’AgroSup Dijon) qui sera assurée par le Dr Elliot Paul Gilbert (ANSTO, Australie). La conférence est intitulée : "Small Angle X-Ray and Neutron Scattering: Natural Tools for Food Science and Technology Research” .

    Résumé de la conférence :

    Small-angle scattering is a natural technique for the study of soft condensed matter providing structural information on the nanoscale. On a daily basis, the most ubiquitous form of soft condensed matter with which we interact is food. At ANSTO, we have developed a programme of research in which we seek to investigate fundamental and industrial problems of national significance in food materials science. Much of this research uses neutron scattering as a key tool to enable structure elucidation.
    One of the most common ingredients in food is the biopolymer blend, starch. It is composed of amylose and amylopectin, packed into complex molecular arrangements that show a high level of organisation over several length scales from the atomic (yielding variations in crystal packing) to granular (on the micron scale). Amylopectin is assumed to contribute significantly towards the structural and physicochemical properties of starch, whereas the location and role of amylose is less understood. Recently, the amylose fraction has been under heavy scrutiny because of its resistance to enzymatic digestion driven by the potential use of high-amylose starches as ingredients in formulating foods rich in resistant starch. The consumption of such materials has been widely implicated to lead to reductions in the incidence of diet-related disease. The vast majority of the food consumed however is not composed of granular starch but is, in fact, processed - often gelatinized and retrograded - thus an understanding of starch structure must also extend to processing. The latter is well suited to neutron scattering due to the highly penetrating nature of the radiation enabling beam transmission through complex sample environments, opening up the unique opportunity to study industrially-relevant processes in real time.
    This presentation will briefly introduce the broad application of neutron and X-ray scattering methods to food-based systems within the 'Food Structure and Dynamics' group at ANSTO with a subsequent focus on our investigations of starch structure.

    Cadre de la recherche

    Les traitements thermiques sont utilisés pour inactiver les bactéries pathogènes et
    responsables de l’altération des aliments. Ils ne sont toutefois pas sans impact sur les
    propriétés organoleptiques et nutritionnelles des aliments. Une des stratégies
    permettant de limiter les traitements thermiques consiste à multiplier les "effets
    barrières" qui inactivent ou empêchent la croissance des bactéries. Il peut s’agir
    d’acidification, de la diminution de l’activité de l’eau ou encore de la présence de
    molécules inhibitrices (ie., acides gras insaturés, tensioactifs, produits de la réaction
    de Maillard, peptides, huiles essentielles). Ces "effets barrières" peuvent avoir une
    action directement sur la thermorésistance des microorganismes ou indirectement
    limiter la croissance des cellules qui résistent aux traitements thermiques. Les
    connaissances sur ces effets barrières utilisés seuls nécessitent d'être développées,
    mais aussi lorsqu'ils sont en association car ils peuvent montrer des effets
    synergiques voire antagonistes.
    Les molécules inhibitrices étudiées seules et en milieux simplifiés de laboratoire en
    tant qu'effet barrière peuvent montrer une efficacité moindre lorsqu'elles sont
    introduites dans les aliments. Ce constat pose la question de l'existence d'éventuelles
    interactions entre les molécules inhibitrices, les microorganismes et les constituants
    et les structures de l'aliment. Nous proposons d’étudier ces interactions dans une
    émulsion modèle, en présence de spores de Bacillus weihenstephanensis (groupe
    Bacillus cereus). Ce programme de recherche s'inscrit dans la continuité du projet
    Acid Impact (KBBE, 2015) : étude des effets du pH, des caractéristiques physico-
    chimiques de composés inhibiteurs et de leur concentration, et du ratio huile/eau (φ),
    sur la germination de spores de Bacillus weihenstephanensis dans une émulsion
    modèle.
