Elieser Salman Posner (born 18 October 1937) is a specialist in Grain Science. He holds a PhD in Grain Science & Industry from Kansas State University.

Education

1960 Swiss Milling School, Graduated with honors.

1969 Milling Science & Management, Kansas State University, B.Sc.

1970 Grain Science, Kansas State University, M.Sc.

1985 Grain Science, Kansas State University, Ph.D.

Career

Following 25 years of work in the flour milling industry, Posner joined the academia to initiate research of wheat processing at Kansas State University.

Between the years 1986 and 1991, Posner served as a tenured associate professor in the Department of Grain Science at Kansas State University. Between 1983 & 1986 Consulted UNCTAD in the Caribbean & West Africa. Between 1986 & 1991 initiated and developed professional activities between the USSR All Grain Institute and the Department of Grain Science & Industry at Kansas State University.

Posner has published numerous scientific papers and books. He has also performed research on wheat flour milling and contributed to various encyclopedias and books on the topic of food and grain processing. In January 2002, Posner worked as a member of a delegation that facilitated the first U.S. Wheat (USW) shipment to Cuba in 40 years. ^[1] In addition, Posner and USW regional vice president Mitch Skalicky met with leaders of the Cuban milling sector and provided technical assistance.

In 1997, he co-authored a book called Wheat Flour Milling which discussed new ideas and approaches to wheat flour milling including raw material, storage, blending, cleaning, milling, conditioning, grinding, sieving, purification, mill design, process control and maintenance as well as food safety, hygiene and mill management. A 2nd Edition was published in 2004. ^[2]

Research interest relates to developments in wheat flour milling. While at Kansas State University, supervised and co-supervised of MSc and PhD graduate students whose work related to wheat quality, and processing technology. Since departing from Kansas State University, Posner served on advisory committees to graduate students in Australia, USA, & Brazil.

Posner consults on grain processing and wheat flour milling to national, public and private organizations in North and South America as well as the Far and Middle East. Since 1992 he has aided multiple organizations in upgrading milling systems, optimizing yield and performance, new construction, and conducting in-plant milling short courses to improve staff knowledge. Posner was involved in setting up flour milling schools in Venezuela, Egypt, and Morocco. During 2019 Posner conducted a four-month short course to Israeli millers, sponsored by the Israeli Industrial Association.
