U.S. Department of Agriculture (USDA) Grant Award  1997-99  ($110,000.): "Chemical Basis of Crust Formation in Deep-Fried Potatoes".  Dr. Blumenthal was the Principal Investigator and Dr. Karen Schaich of Rutgers University, the Co-Investigator, jointly leading a university/industry team to study lipid-polysaccharide interaction in potatoes fried in oils of varying stages of degradation, and determine the relationship between frying oil chemistry, lipid-polysaccharide complexation, and structure and texture of potato crust.   This project has agricultural, nutritional, and economic significance because of the extremely widespread consumption of fried potatoes. It is estimated that of the 16.5 million tons of potatoes produced annually, fully half are used for French fries or potato chips.  The statistics on the value of oilseed crops used to produce the costly fats and oils used in deep-frying are equally impressive.


This industry/academia project was the first instance of Rutgers University’s being a paid subcontractor to a private research company, and required a new type of contract.


Descriptions of major work:

A New Paradigm of Deep-Fat Frying

Deep-fat frying is one of the most widely used methods of food production, and is practiced all over the world. It is a $75 billion a year industry in the U.S. alone, and estimated to be twice that worldwide. An extremely wide variety of types of foods are fried and oil blanched, and frying fats and oils are valuable and ever-more-costly agricultural commodity products.  Extensive research is being done in the U.S. and abroad on new oilseed varieties, genetically enhanced oils, and processes and procedures to improve the nutritional profile, stability, and other important properties of fats and oils used for food, and, in particular, for deep frying.  In addition, the quality, safety, nutritional and aesthetic values of many agricultural products - the foods fried - are affected significantly by the frying process. The proper conduct of frying operations is essential for food quality, safety, nutrition, and economics.  Until now, it has been largely an art.


Dr. Michael Blumenthal has developed a powerful new scientific understanding of the dynamic forces and factors that affect frying processes, and his research has led to a new paradigm.  He has approached the problem of the degradation of edible fats and oils during frying processes from a physical chemistry / engineering / systems perspective, focusing on heat and mass transfer, going beyond the traditionally-studied organic chemistry of frying oils.  His research explores the entire frying system and the interactions between frying fats/oils and the foods fried, the equipment and processing aids used, ingredients coming in, and the complex chemistry at work between the heated surfaces, the degrading oil, leachates from the food, entrained and reactive oxygen, and the constantly changing surface and interior of the dehydrating food.


Dr. Blumenthal has proposed (and subsequent research has confirmed) a new paradigm of surfactancy as the mediator of heat transfer between frying oil and largely aqueous food. The theory states "Surfactants are responsible for the surface and interior differences in fried foods, as induced by aging oils." Using the systems approach and analyzing thousands of samples, Dr. Blumenthal's laboratory established a large database from which he deduced a simple mathematical relationship between the concentration of surfactants and the variations in food quality typically seen in food production and food service. Surfactants increase as oil is used and degrades. Control of surfactants enables proper cooking and optimization of food quality, food stability, oil economics, and system productivity.


However, in degrading oil, as surfactant concentrations are increasing, leading to the oil "wetting" the food, the specific heat of the oil is increasing from that of fresh oil (linearly) with the accumulation of polymer species, which form due to oxidation and thermally abusive conditions. This increased specific heat causes poor cooking due to insufficient heat being available in the oil on the wetted surface. The formation and accumulation of smaller molecular species such as free fatty acid increases thermal conductivity, which factor controls the rate of replenishment of energy to oil at the food's surface. Without proper heat transfer into the interior of the food, even the microbial safety of fried foods such as chicken is compromised.


The Gaussian curve that describes the relationship between the surfactant and polymer and other polar material concentrations and perceptible food quality has been named the Frying Quality Curve, and it portrays regions corresponding to initialization, normalization, optimization, degradation, and termination of the suitability for continued use of a frying oil.  This Frying Quality Curve has been widely reproduced, cited, and quoted by other researchers, teachers, and authors, as the model that now leads to insights critical to the understanding of the chemistry of frying oil degradation.


Prior research has tended to focus on the extremes of how to refine fresh oil, or, conversely, the potential health hazards of abused oils.   Dr. Blumenthal's work concentrates on how to optimize and maintain frying processes to sustain the desirable, central properties of the oil in order to produce the best quality food in the most economical way. The new paradigm of frying is therefore not only an original and creative contribution to a fundamental understanding of the chemistry of complex food systems, but is also a practical basis for producing a superior array of quality food products: an ideal combination of the theoretical and practical in food chemistry and food technology.

Solventless Chemistry

Dr. Michael Blumenthal has invented and patented a novel chemical reagent delivery system that has enormous potential to revolutionize the way many chemical measurements are made. A series of gels, of varying properties, depending on the application, enables chemical reactions, such as color tests, to be performed entirely without solvents or toxic materials, in disposable vials, thus eliminating typical hazards of chemicals to the worker and the environment, as well as permitting real-time quality control, by allowing measurements to be made right at the production line, thus "taking the lab to the line", even where food is being processed/produced. In addition, the tests can be, and initial applications have been made quantitative and highly correlated to corresponding laboratory procedures.  Their ease of use makes it possible for non-chemists to perform tests with confidence and speed, and eases the workload burden on agricultural and food chemists by allowing screening testing to isolate from large numbers of samples, only those requiring closer investigation.


Working with colleagues, Dr. Blumenthal has developed a first application of solventless chemistry tests for use in deep-fat frying control.  As a natural outgrowth of the new paradigm of frying, described above, process control is facilitated by being able to make the relevant rapid measurements directly at the site where deep-fat frying is being done. Therefore, the first series of tests commercially available  that use the new solventless chemistry are the VERI-FRY® internationally trademarked tests for free fatty acids, alkaline surfactants, and total polar materials (total accumulated non-triglycerides).


These tests are used by hundreds of snack food producers, industrial manufacturers, and food service establishments, as well as regulatory inspectors and also researchers who wish to develop products or processes with speed and efficiency by being able to make rapid and accurate measurements at low cost and without environmental hazards. The solventless chemistry technology combines simplicity with sophistication and is virtually limitless in application.  An extension of existing tests into the measurement of fat  rancidity  in  milk  has  enormous  economic  ramifications.    Dr.  Blumenthal  has prototyped over 300 chemistries with this new technology. The portability, compact format, and archival character of the tests (finished tests can be stored and re-read later or at another location!), coupled with their reliability, safety, and speed, offer tremendous access to those, including in developing economies, wishing to have real-time quality control, do rapid screening testing, or demonstrate chemical principles in teaching situations where chemicals are now severely limited due to hazards and liability potential or environmental problems.



Appraisal and evaluation:

Dr. Michael Blumenthal's work has spanned an extremely wide array of contributions to, and studies of, the chemical sciences, and in particular as they apply to the products of agriculture and their manufacture into food products.  He has been a member and leader of research teams creating key processes fundamental to food processing today. At Libra Technical Center, his work has directly affected more than 500 companies for which he and his colleagues have consulted and performed laboratory research and analyses. More than 400 organizations have used the new rapid testing technology to improve quality control and process economics.


In the last 30+ years, Dr. Blumenthal has directed operations resulting in more than 500 industrial consulting reports available on-line within Libra, in addition to his publications and private industry reports, and he has overseen the preparation of more than 1000 on-line analytical reports for a global customer base.  Thus he has founded an enterprise in which independent science can be conducted confidentially and with an enormous database of recorded knowledge and experience behind it, as well as an enterprise that creates new technologies and new products for application of chemical principles to better foods, fats, and oils.   Dr. Blumenthal's experience and ability to understand and translate extremely complex chemical systems into elegant, reliable, simple tools is a very rare combination.


His new Paradigm of Frying is not only a creative and powerful achievement in a specific area of food chemistry, but also serves as a model for an approach to solving problems in the complex world of the total chemical events which occur in a living system from agriculture which is brought into an engineering / manufacturing environment.  He has shown the way for an extremely useful strategy for converting chemical principles to the economics of food production.


The power to predict is one of the most compelling aspects of Dr. Blumenthal's contributions. Both the Frying Paradigm and the Solventless Chemistry technology are a direct outgrowth of the pathway that began with Dr. Blumenthal's studies on saliva, as part of a cystic fibrosis project.  This study enabled an understanding of physiology and the limitations of sensory work.   In his Master's Degree research on onion flavor chemistry, Dr. Blumenthal was able to understand what to look at when doing mathematical pattern recognition.  In his Ph.D. research, he was able to achieve an unparalleled degree of correlation of instrument measurement with the human sensory experience: by the use of computerized pattern recognition methods, he was able to achieve nearly perfect prediction of the sensory evaluation by using only 2 peaks from a complex flavor chromatogram. The technique he developed is now used by the most advanced flavor houses in the creation of natural-tasting and -smelling analogs made from synthetic materials.


The New Paradigm of Deep-Fat Frying has taken thousands of chemical events, in all the  numerous  combinations  and  permutations  of  oils,  foods,  frying  systems, environments, personnel, etc., and reduced the measurements needed to predict food quality, shelf-life, oil usage, and so on, to only 3 tests, one of which (Total Polar Materials) has regulatory applications in Europe, where the oil must be discarded before it reaches the statutory limit, and yet for which the corresponding laboratory procedure is so prohibitive in its cost, time, and expertise required, that only after-the-fact compliance can be established.


Through Libra's Solventless Chemistry technology, these 3 tests can be performed by anyone, anywhere, anytime, to achieve true process and quality control. They allow the prediction of food quality, shelf-life of packaged foods, and process economics, all from the oil's condition.  They put safe, simple and accurate measurement systems in the hands of those who must make decisions before things go wrong. The technology can be extended to an enormous array of applications and solves many of the problems that prevent easy and frequent chemical measurements and studies today. This is truly a contribution to the ease and widespread use of chemistry for everyone's benefit.


Another important aspect of Dr. Blumenthal's work in food chemistry has been his teaching role. He is consistently selected as among the best faculty in his adjunct professor lectures and short courses at Rutgers Univ. and elsewhere.  He is invited to speak all over the world, and has given many presentations and seminars at industrial firms, universities, research institutes, and government agencies, for example, in England, Spain, the Netherlands, Scandinavia, Japan, Malaysia, Germany, France, and all over the United States. Through short courses and symposia, he has taught many hundreds of scientists the principles of food chemistry in a total systems approach.  The new paradigm has led to major advances in the application of food chemistry to food chemical process engineering, and provided a new generation of researchers with fresh directions to explore. Graduate programs now exist inspired by Dr. Blumenthal's work and teachings, for example:


Prof. Brian Farkas :Univ. of N.Carolina,(now at Perdue) bulk heat & mass transfer studies

Prof. Rosana Moreira, Texas A&M Univ.: heat and mass transfer with regard to   conversion of ingredients to a food

Prof. Philip Handel, Drexel Univ.: strength of surfactancy effects

Prof. Israel (Sam) Saguy, Hebrew Univ. of Jerusalem: understanding the

interface between heat transfer medium and surface of cooking food

Prof. V.M. Bala, Univ. of Georgia: textural changes induced in food by aging oil

Prof. Karen Schaich, Rutgers Univ.: lipid-polysaccharide interactions


The potential importance and impact of the Solventless Chemistry technology are enormous, and have only begun to be imagined. In an age of increasing health, safety, and environmental concerns, such a measurement science can only have widespread benefits, no matter what the arena of application, but especially so in the field of food quality control, where the measurement technology must not threaten the product or the environment, and so until now, no quantitatively reliable chemistry could be done in the vicinity of the food itself.  For lab, plant, field, restaurant, institutional, or classroom use, this technology can revolutionize measurement science.


Dr. Michael M. Blumenthal has advanced food chemistry, the proper processing of the products of agriculture and synthesis so that they are enjoyed and not wasted, and the measurement sciences in ways yet to be fully realized, but of undoubted importance and power.  He has shared his findings and insights widely, to the benefit of industry, government, and the academic world.

As with any other scientist working in organizations and consultancies where updates, reports, white-papers, etc. are expected periodically, Dr. Blumenthal has "published" literally thousands of "reviewed" papers that will never be seen outside the organizations for which they were written under strict confidentiality.  In order that some aspects from this private work are not lost, Dr. Blumenthal, with the cooperation of his associates and clients, has embedded special insights and teachings in his short courses, graduate classes as a Lecturer at Rutgers University, and other schools around the world, and in mentoring many interns, graduate students, and employees working in the technology companies he founded since leaving larger industry.


Dr. Blumenthal is currently writing books and monographs for eventual publication.  He is studying new fields including development of optimized processes and products from botanicals, biofuels from renewable and recycled oils, purification and standardization of food, flavor, texture, and fragrance materials at “village farm” level, and the total synthesis of foods from non-cellular sources, for military, rescue, and long duration space missions (like the “Food Replicator” from Star Trek®) based upon his 1970 “how-to” seminar at Rutgers University.


Also, in returning to his original roots as a physical chemist in rheology, chromatography, thermal analysis, and microscopy. Dr. Blumenthal is training others, and applying that talent to “industrial forensics”, a nascent field requiring a very broad base of knowledge of commodities, technologies, and experience of consumer and machinery products and how they are made.  Dr. Blumenthal has, over many years, expanded his consulting practice to include expert witness services for the chemistry, engineering, food science, materials science, personal care, consumer products, packaging, lipid technology, stability, quality assurance, and laboratory management fields in which he is recognized.
