The Beano Chronicles

4 Replies

Being a scientist, I am interested in natural phenomena. And, being a gastronaut,  I am naturally keen to explore the distant reaches of the food universe.  Generally my voyages into multidimensional food space are uneventful. But now and then I encounter foodstuffs that push back. Food that does pressure-volume (PV) work on the internals.

Some foods are capable of generating many moles of gas phase product that is appreciably insoluble in the digestive fluids. The result is an inflation of the gastric spaces and prompt notice to the brain of distress.

Fortunately the good folks at Beano have a commercially available product that in my hands or … ahem … elsewhere … makes a dramatic difference in the discomfort level associated with certain legumes. The secret of this wonder of science is alpha galactosidase. When taken before the first bite of PV generating foods, it causes a drastic reduction in the inflation of the large intestine. This enzyme aids in the hydrolysis of troublesome saccharides that are otherwise left to travel from the small to the large intestine where the gut flora go to town.

All the legume eater has to do is to chew 2 or 3 Beano tablets right before the first spoonfull of chili or pintos. In my half dozen live fire beano tests and one frightening control experiment, I have to say that I am a believer. I am grateful and my family is even more grateful.

Science for the betterment of mankind. Ya gotta love it.

The Chemical Entrepreneur. Part 2.5.

11 Replies

There are as many ways of starting a chemical business as there are people starting them. Entrepreneurs range in profile from smooth talking slicksters to sober, ROI-calculating engineers. Entrepreneurs can also be rather unruly folk. It is not automatically true that business founders are inherently talented at designing and running orgainzations. In fact, they are frequently poor at it.  But, successful founders are usually highly focused and are able to attract resources.

A common motivation for starting a business is that the founder is possessed with existential certainty that he/she can operate a business venture better than, say, a former boss or rival. A business founder may be a free spirit, refractory to sensible advice, or may be a solemn Harvard MBA operating by the book. It is not uncommon for a founder to have had several previous failed ventures prior to a successful one.

And make no mistake, the sense of power that a founder feels in the execution of a business plan can be as addictive as heroin or crack. Once a person has had the experience of successfully gathering resources and then allocating them to leverage progress to a goal, they are forever changed. Whether or not they continue the role of managing funds or personnel, their eyes have been opened to the real meaning of power.

Power is the ability to allocate resources.

No matter what kind of chemical business one wishes to start, it is crucial to understand that it will require the accumulation of some kind of resource that you can apply to a problem. That resource can range from your technical reputation, 30 days net of commercial credit, VC monies, or a chemical processing plant. It is all a form of leverage toward the greater goal converting streams of goods and services into streams of cash.

Try to get cash flowing from sales as early as possible. Choosing a Market-Pull activity is the best way to do this.

A chemist starting up a business is able to choose several kinds of general business activities.  If you want to be a consultant, you must determine the boundaries of your knowledge and then find demand for that expertise.  If you are truly an expert in a field, then more likely than not you know who might buy your services.

If you choose a Technology-Push approach, try to target customers who are willing to be early adopters.

A chemist may be well situated to start an operation offering analytical services. In that case, the enterprising analyst needs to know about underserved demand out in the marketplace. You need to offer a service that prompts people to send a purchase order to you.

If your startup is a one-act pony, it is critical that the pony actually be able to jump through the flaming hoop as advertised. Try to avoid one-act pony business plans.  Find Market-Pull products to pay the bills while your Technology-Push products are under development.

A chemist is in a great position to get into formulations.  While this might not be strictly a “chemistry’ activity, the walking-around-knowledge of chemicals that a chemist might have probably well exceeds the basic chemistry knowledge of many “experts” in the formulations business. However, a chemists general knowledge may not be applicable for direct application to formulations. A formulator must accumulate specialized knowledge and analytical methods for the materials they handle, including things like rheology, cloud and pour points, fungal contamination, and miscibilities. The level of infrastructure for doing formulations can be dramatically less stringent than chemicals manufacturing as well, requiring less startup capital. That said, formulations may be in demand at the large scale. Puttering around at only the less-than-drum scale may have no future.  Again, to be a formulator you need to know what is in demand.

Remember-Sometimes it is dumb to be too smart about things. Be customer oriented. Be honest about strengths and weaknesses.  Learn the difference between smart and cagey. Dick was a cagey businessman. Don’t be a Dick.

Fine chemicals manufacture has many success stories.  Alfred Bader started his Aldrich empire making what we now call Diazald. Bader was extremely customer service oriented and I believe this was the key to his success. He visited laboratories and asked workers what they needed. If the request was reasonable, he would put the material in the catalog collection. If the chemist-entrepreneur desires to start a catalog fine chemical company to sell reagent chemicals and widgets, then I would advise making a study of that business arena.

An understanding of the regulatory compliance world is critical as well, especially relating to the Toxic Substances Control Act, TSCA. A company may have to start out as being a provider of ‘R&D Only’ products. To freely sell commercial quantities of specialty and fine chemicals, a substance must be on the EPA’s public or confidential lists. If not, then permission must be granted by EPA. This will require a special filing which discloses its manufacturing and/or use process, Personal Protection Equipment (PPE), fugitive dust and corresponding controls on exposures to workers and the environment, vapor releases and method of control, a disclosure of how much of the New Chemical Substance (NCS) gets into the environment, any and all available toxicity data, a Safety Data Sheet, physicochemical data, waste NCS disposal, batch size and yearly production. For less than or equal to 10,000 kg per year a Low Volume Exemption (LVE) can be filed. This is an abbreviated version of a Pre-Manufacturing Notification (PMN) filing which will be examined in greater detail and will take much longer for EPA to complete. EPA has the right to require the submitter to collect certain kinds of toxicological data at the submitters expense. These tests are standardized and are performed by certified labs.

Most advisors to entrepreneurs will say that the prospective businessperson is well advised to put down a written plan. This is important on many levels. The act of writing a business plan is useful to the entrepreneur in several ways.  It causes the writer to focus his/her ideas and energy as well as to clarify the goal and how to track towards it. A well written business plan is critical if you need to attract funds to get the operation started. Investors and bankers need a document to study and to bring before others for analysis and buy-in. Just gotta have it.

Starting a drug company is going to be quite difficult for a few isolated chemists to do. It is a complex and insanely expensive and risky business that requires a wide diversity of players to be on board and committed. Somewhere you have to get an MD or MD/PhD, finance people, former pharma executives, regulatory affairs peoples, etc., on the board to add gravitas to your plan. A whole circus of expensive prima donnas. Sounds like a nightmare to me.

New Job Description- Negativist

Getting buy-in from a diverse cast of characters is one of the between-the-lines features of  my job description. Everyone has this problem to some extent. I will admit that I’m quite lucky- Instead of having a single type of difficult character, I have a wide variety of  them. I should feel blessed.

Problem solving is one of the activities where divergence commonly occurs. I’m pushing for this, you are pushing for that. The usual stuff. You advance your arguments and they stand or fall on their merit. But in the end, there has to be convergence. We all have to agree on a path forward.

But what to do if you are the only one trotting out ideas? What if there is another form of problem solving where one person advances an idea and everyone else spends their creative faculties lobbing bombs at it and citing reasons why it shouldn’t be tried? Rather than posing alternatives, the negativist op-poses but is unable to pro-pose.

I will confess that this relates to one of the great disappointments of adult life.  A lot of ones adult cohorts reach a tidy level of comfort early in their lives and stay there for the duration. Many people are terrified to leave their comfort zone and take a walk on the wild side. Wading into unfamiliar territory and trying to build a structure amidst the reeds and swamp creatures. Intellectual land lubbers are fearful of residing outside of known space.

I have have a long list of  weaknesses and  limitations as well. I doubt that I’ll be quitting my job to live in a hut in Phuket and tend bar, fun as that might be.

Arizona Scientists Discover First Inert Enzyme

5 Replies

December 3, 2008, Arroyo Oceanographic Institute, Guapo, Arizona.  Oceanographers at the Arroyo Oceanographic Institute (AOI) at Pultroon College have announced the first of what is believed to be a series of inert enzymes. Scientists discovered the mysterious enzyme in the anterior appendix of the giant salt water catfish while on a benthic noodling expedition off the coast of Tierra del Fuego. Dubbed “Uselase”, the faux enzyme is thought to be the result of a non-lethal mutation.

Dr. Hoechstus Van Toogenblatt, principle investigator on AOI’s 160 ft research vessel Belle Stugatto, noted that the peptide did hydrolyze and release glutamate during the cooking process. “Eet eez gud fer somting, ja?” he said wistfully, “makes a helluva chowder!”

Slippery Slope for India

Beyond the horrific reality of the dead and injured in Mumbai from last weeks terrorist attack is the uncertainty of ramped up state tensions between nuclear India and nuclear Pakistan. Pakistani’s weary of home grown terrorists and foreign instigators can sympathize with the fear and revulsion felt by Indians who are stunned by the event. But citizens of Pakistan are indignant about accusations of state involvement in the attack.

Given the weakened condition of the government in Pakistan and the sensitivity from chronic conflict with India, it is hard to draft a rationale describing what benefit the government of Pakistan might have in such dirty dealings.

We must trust that India can take a lesson from US experience with the attack-retribution reflex and find a way to prosecute those who planned this savage crime through police work rather than invasion across borders.

Melamine Spill on Isle Five!

5 Replies

The reality of melamine in animal feeds and milk products has crossed the ocean and landed on the shores of North America. Trace levels of melamine have been detected in certain baby formula products in the US.

The National Milk Providers Federation (NMPF) has responded with a statement on their position on adulterants. Having been in the milk processing business as a quality control chemist, I can add that my experience with the industry is consistant with the statement by the NMPF.

To understand the true level of confusion and diverse practices relating to this problem, it is important to note that the analytical methods used by US milk processors are insensitive to the presence of melamine itself. Here is why: Raw milk arriving to a processing facility is tested for the presence of antibiotics, fat content, flavor, pH, and total solids. To my knowledge, there is no batch QC protein analysis anywhere in the US manufacturing flow. In Asia, apparently protein analysis is common. 

The practical consequence of this analytical protein blindness in the US is that there is no benefit to adding melamine to milk because pricing is not determined by protein content. Milk is sold by the pound and its premium value is determined by the butterfat content.

Milk has been subject to many kinds of fraudulent modifications in the past. Sour milk has been neutralized with caustic. Today all milk is taste-tested for off flavor. Milk has been diluted for higher profit. Today all raw milk is tested for % solids and % fat to detect dilution. It should be above a certain minimum on both accounts. Cows have been milked abusively into chronic mastitis and given antibiotics. All milk is now tested for antibiotic residues via chemical and microbial assays. Finally, milk that contains an excessive microbial loading is rejected.

If Chinese milk processors adopted a similar testing protocol, the benefit of direct adulteration of milk with melamine would disappear. The effects of melamine-laced cattle feed is another issue. I have not heard of studies that connect ingestion of melamine contaminated feedstocks to milk contamination. Perhaps this has already been done.

According to the Wall Street Journal–

Dr. [Stephen] Sundlof said the melamine traces stemmed from the products coming in contact with the chemical during processing. The FDA approved melamine as a “food contact substance” about four decades ago.

The article continues-

The FDA said last month that it’s safe for consumers to eat most food with melamine below 2.5 parts per million, but infant formula was the exception. “FDA is currently unable to establish any level of melamine and melamine-related compounds in infant formula that does not raise public health concerns,” it said.

I am heartened to see that the FDA is reluctant to establish a threshold for safe consumption by infants. But at the same time, the matter of a 2.5 ppm threshold for everyone else amounts to a sh*t sandwich for the public.

The levels detected by US companies and agencies seems rather low. Again, from WSJ-

A spokesman for Mead Johnson Nutritionals, owned by Bristol-Myers, said the company’s own tests haven’t turned up any melamine, and the FDA tests turned up melamine levels “lower than the 0.25 parts per million limit that can be measured by the published FDA test method.” Mead Johnson, he said, maintains “stringent standards at all our manufacturing sites to ensure the high quality and safety of our products that our customers have come to expect.”

Dr. Sundloff said the melamine detected was tiny. Out of 87 samples, it found one sample with 0.137 parts per million and 0.140 parts per million on a verification test.

While toxicological threat to US consumers at the sub-ppm level is unclear at the moment, what seems to be lacking at FDA is a discussion as to the need to allow any level of melamine in any consumable.

Here is what is clear to Th’ Gaussling:

There is no overlap in the material streams of melamine or melamine resin manufacture with any dairy product. No dairy operation should reasonably expect to require containers of melamine monomer in its warehouse, nor should any supplier to dairy product manufacture.

Melamine contamination by contact exposure to melamine resin components can be averted by the use of many other food grade materials of construction, i.e., stainless steel.

If melamine is detected in food articles, it is the duty of the manufacturer to promptly audit all suppliers and eliminate the source of contamination.

Rather than tolerate and regulate the presence of a material whose only purpose is to perpetrate fraud, the FDA should ban food products containing detectable amounts of melamine. If the FDA goes forward with acceptable levels of melamine in dairy products, suppliers would begin to game the system. In a short time, ppm levels of melamine will be considered “normal” and suppliers of melamine contaminated feedstocks will be legitimized up to the regulatory threshold. 

A firm stand by regulatory agencies will strengthen the motivation of manufacturers to maintain strong audit trails and take away the financial incentive to use this fraudulent additive.

Weighty Cogitations on Borohydride

10 Replies

I have been making a conscious effort to find ways to use borohydride compounds rather than just default to the mighty gray sledge hammer- LAH. There are numerous reports of diverse and wonderful means of activating borohydride to reduce the more refractory functional groups. Recently I prepared and used Zn(BH4)2 on a new substrate. Initially, it appears to work poorly. The grey wall cake seems to contain metallic zinc. If preferences mattered, I’d prefer see electrons reducing my substrate rather than Zn (II) to Zn.

You can’t always get what you want.     M. Jagger

Failing to Ask Better Questions

We may be entering a time of greater economic hardship than many have known in their lives. The great age of mass consumption, non-returnables, and disposable goods may have peaked.  Boarding the Hummer or the Escalade to drive 5 miles to buy cigarettes and a Big Gulp may be a thing of the past for a greater number of citizens. Americans will have to adopt a lifestyle much more akin to Europe or Japan- reduced living space and reduced (kg of crap)/(person year), reduced portion sizes, more walking, local shopping, and increased use of rail transportation.

The Oil Shock of Summer 2008 snagged the suspenders of this nation of hydrocarbon addicts, sending us reeling into the election/market crash machinery like a drunken farmer pulled into the thresher. Out the back end of this nightmare comes the bloody oat chaff to hint that something horrific happened. Reality strikes, then … silence.

In spite of the plurality of media outlet channels into our collective consciousness, few infotainers are drilling into the core of the problem. The pace and timing of commercial media sets the rhythm of infotainment metered to the masses. Photogenic talking heads selected for their appeal read predigested content for broadcast to attention deficit channel surfers. People dulled by the sheer magnitude of content-dilute information streams and dazzled by the production value of infotainment are compelled to switch on HBO and hide from the world.

Here is what we must do. We must see to it that better questions are being investigated. Instead of asking about the replacement for gasoline, we must ask for a frank disclosure on the sustainability of high consumption. Instead of asking for better or hybrid automobiles, we must frame questions around the concept of a mass transportation network. How can we get intercity rail up and running? How can the Detroit automobile manufactures be cajoled into entering the rail infrastructure business? Where is the hydrogen going to come from to fuel the hydrogen economy? Does it make sense to consume energy to generate hydrogen and then turn around and burn it for propulsion?

The best answers come from the best questions.
