Title: My Vision For Grain Quality And Structure Research And Biographical Sketch


1
My Vision For Grain Quality And Structure
Research And Biographical Sketch
  • Sumana Chakrabarti Bell, Ph.D
  • Presented at USDA, Manhattan, 1/10/08

2
Outline
  • Sumanas Biographical Sketch
  • Grain Quality Research Background
  • Vision
  • Strategies
  • Managing Change
  • Management philosophy
  • Summary

3
Who is Sumana? Heritage Family
  • Native of Calcutta, India
  • Early schooling in small town in India
  • One husband (pharmacist), two cats

4
Education and Career
  • Ph.D., Polymer Physical Chemistry, University of
    Minnesota, USA
  • M.Sc., Physical Chemistry, Calcutta, India
  • Program leader, Fracture Fluid Rheology (British
    Petroleum in UK, Schlumberger in USA, France)
  • Program leader, food and dough rheology (Kraft,
    Chicago and General Mills, Minneapolis)

5
Prior Research
  • Ph.D Gelation of rigid rod polymers by spinodal
  • decomposition of phase separation
  • Strength of physical gels f (mechanism of gel
    formation)
  • Oil-field Rheology control of fracture fluids
  • Fluids carry proppant
  • Create filter cake to prevent
  • fluid leak-off

  • Clean break-up

6
Key Take Away Oil-Field Research Flow affects
cross-link density of chemical gels
In Waring blender, brittle gel In
porous media, ropy fluid Insights applied in
developing continuous processing of yogurt
7
Prior Research
Food Dough Converting Art To Science
  • Defining performance using mechanics
  • Converting learnings into practice
  • Relating performance to structure composition

8
Key Take Way Plasticity is Key
  • Dough changes with deformation
  • The rate of change determines end-use quality

9
Grain Quality Challenges to The US Farmers
  • In farming, everybody makes money except the
    farmer
  • …….… Michael Pollen, The Omnivores
    Dilemma
  • Excessive emphasis on processed foods and
    industrialization have decimated self-sustaining
    farms
  • Soil quality threatened from excessive farming

10
Grain Quality Challenges to The US Farmers
  • US is the largest exporter of wheat
  • Faces competition from abroad (Canada, Australia)
  • Competition claims superior consistency
    quality
  • Effects of global warming on yield and quality
    are un-certain
  • Consumers want more value in foods (convenience,
    health, nutrition)

11
Grain Quality Opportunities
  • Globalization localization
  • More markets open to farmers
  • Energy producers , Pharmaceuticals
  • Demand for whole grain products is on the rise
  • Market wants new products (health additives,
    processing aids, shelf-life quality aids)
  • Tremendous advances in technology that could be
    used to facilitate grain quality inspection

12
Grain Quality Challenges to Innovation
  • Yield
  • Grain health
  • Milling quality
  • Protein quantity
  • X Protein quality
  • X End-use quality
  • Need to have the know-how to relate all quality
    attributes with structure and composition for
    faster success

13
Vision for Grain Quality Research
  • We want to empower USDA and thus, US farmers,
    with options for attaining sustainable
    competitive advantages, by adding value to
    existing applications , by leading innovations
    and by growing and supplying grains that are
    differentiated from competition on the basis of
    superior functionality and quality, in the
    current climate of global competition

14
Strategies
  • Develop a center of excellence in grain quality
    analysis thats effective in developing new
    technologies and in implementing current
    strategies of USDA
  • Transfer research results into production and
    commercially usable strategies for U.S. farmers
    to serve the food and non-food sectors of
    pharmaceuticals and energy
  • Introduce educational programs for the customers
    and participants technical and non-technical
    audiences

15
Center of Excellence in Grain Quality
  • Disappointing progress in dough rheology,
  • (handicaps research impact on agronomy)
  • ….. Don Kasarda (USDA), Gluten Workshop,
    2006
  • Follow Ed Bagleys footsteps and make USDA again
    the leader in fundamentals of grain processing

16
Center of Excellence in Grain Quality
  • Build a state-of- the- art laboratory thats
    capable of utilizing structure end-use
    performance of grains to add value to grain
    production
  • Predictive methodology for processing operations
  • Instrumentation to test the physics as well as
    the chemistry
  • Capability for small scale simulation of novel
    processes to test research hypotheses

17
Center of Excellence in Grain Quality
  • Make structure material science impactful
  • Add processability and consistent performance
    to the list of quality attributes
  • Explore the non-linear relationships in
    converting grains to products and develop novel
    products and processes
  • Develop predictive technologies to assess
    quality for farmers, for processors and for
    crop-breeders

18
Center of Excellence
  • Innovate
  • Develop value added grains (wheat, sorghum, rice)
    and additives
  • Easy milling wheat without compromising end-use
    quality
  • Processing aids
  • Sorghum flour for bread-making?
  • Pharmaceuticals , Oil-field chemicals,
    Bio-degradable plastics
  • Develop easy to use tools and methods to monitor
    quality

19
Center of Excellence in Grain Quality
  • Innovate
  • Collaborate with DOE funded bio-fuel research
    centers to utilize external RD facilities and
    expertise
  • Develop more efficient processes and materials
    for generation of bio-fuels
  • Enzo-rheology is critical to rate of production
    of Ethanol
  • Collaborate with pharmaceutical RD organizations
    to develop novel applications of grain-based
    materials
  • Hydrogels?

20
Implementation Of Research Into Practice
  • Collaborate with industries and USDA partners
    from the start to ensure buy-in from customers
  • Patent technology as and when appropriate
  • Build credibility
  • Publish
  • Hold training classes
  • Consult for industries

21
Managing Change
  • Current Research Environment
  • Distrust for fundamental research
  • Lack of funding
  • Shifts in business priorities
  • More focus on shorter term research by industry
  • Sign of Hope
  • Break-through technologies are in demand
  • US industries are not doing it!

22
Managing Change
  • Special Challenges To Grain Scientists
  • Industrialized food production systems demand
    linearized processes
  • consistency, predictability, interchangeability
    and economies of scale
  • But, agronomy is not linear
  • Grain based products (wheat flour dough, in
    particular) are also non-linear in behavior
  • Manage non-linear materials for linear
    expectations

23
Managing Change
  • Things to do
  • Encourage scientist to develop collaborative
    programs with food and bio-fuel industries
  • Seek corporate funding
  • Undertake shorter term research
  • Maintain USDA tradition and initiate change
  • Have small successes --- frequently
  • Collaborate, collaborate, collaborate

24
Management Philosophy
  • Tell me and I'll forget show me and I may
    remember involve me and I'll understand.

  • …………..Chinese proverb
  • Filament stretching device
  • ALE training course

25
Management Principles
  • Lead by vision and empowerment
  • Team-work always value and incorporate
    team-inputspreserve the best
  • Focus on objectives and encourage individuals to
    realize their full potential
  • Grow effective scientists and engineers
  • Be challenged
  • Celebrate success and have fun

26
What Can I Bring To This Center
  • Industrial leadership and practical management
    philosophies
  • Practical, industrial knowledge with American and
    European corporate experience
  • Building teams across the nation among
    corporations, academia, and government
  • Multi-disciplinary and multinational approaches
    to solve scientific challenges
  • Proven consultancy-based contacts with major
    industries
  • Unique knowledge from food rheology research
