Testing and Analysis for Measuring Food Qualities

 

 

A food company seeks ways of objectively measuring and analyzing taste, mouth feel, texture, flavor, and eating quality of foods, leading to an analysis method that is accurate and repeatable across many foods and across time.

Analytical Technique for Healthcare and Industrial Applications

Aria Analytics is commercializing a novel analytical technology to characterize liquids for healthcare and industrial applications. As a drop of liquid evaporates on the vibrating quartz sensor, it undergoes distinctive phase changes representing the unique chemical and physical characteristics of the sample. This unique “fingerprint” represents information that is not readily available from any combination of analytical methods currently in use.

Microbial-Based Lawn-Care, Pond-Care, and Cleaning Technologies

Proprietary microbial systems use naturally occurring microbes in lieu of chemicals in fertilizers, microbial inoculants, cleaning products, and pond treatments. Products are based on incorporating beneficial micro-organisms with a variety of task-specific organic surfactants, microbial nutrients, fertilizers, cleaning agents, and bio-polymers. The micro-organisms produce enzymes that continue to work even after cleaning, or — in the case of lawn and pond care — continue to make the soil or pond healthier even after fertilizing the plants or inoculating the water.

Methods to Detect Minute Quantities of Acrylamide in Foods

A large global food company seeks a rapid, inexpensive, and reliable test that can detect even small levels of acrylamide in fried snack foods. What is desired is a rapid, simple, inexpensive method that could be performed essentially online in a fried snack plant by line operators or quality assurance analysts. Ideally, it would require little, if any, sample preparation, would provide results in less than one hour, and would be selective, sensitive, and quantitative for acrylamide in a potato chip.

Unique DNA Signature Identifies Organism’s Species

Unique genetic markers called oligonucleotides can provide swift identification of a known organism or rule out an organism from known genomes. This software technology provides a way to generate thousands of such markers and provides a searchable database of chromosomal sequences for over 100 pathogens and near-neighbor organisms, unique plasmid sequences, and markers for virulence and antibioticresistant genes in a platform-independent format. Using the technology, the existing database can be extended to any DNA-based organisms. With as few as 20 DNA fragments, the system can achieve a 99% confidence of no false negatives against a library of samples.

Finger Seals Replace Brush or Labyrinth Seals

Finger seals are non-contact fluid seals similar in purpose to labyrinth or brush seals in that they act as a barrier between two areas of the same or different pressures, but allow a rotating shaft to penetrate through them from one side to the other. Applications include sealing rotating parts in turbine engines, pumps, rotating air motors, or other applications where a shaft needs to be sealed against incursion or excursion of oil, air, water, or other gases or fluids.

Topical Delivery for Analgesic Medications

A company seeks new non-oral delivery mechanisms for analgesics. Non-oral methods avoid the stomach and the intestine. These new mechanisms might be topical; that is, in contact with the outer layer of the skin. However, other nonoral mechanisms are open for consideration. Non-oral administration bypasses both the stomach and the liver and can deliver more active to the bloodstream more quickly per dose.

Heating Different Zones of Food in a Microwave Oven

An organization seeks technology to enable foods to become crispy when heated in a home microwave oven. The outer surface should heat and become (or remain) crispy, while the interior body of the food should heat only as appropriate. The organization seeks materials, ingredients, or other technologies that enable the zones, while physically part of the same food, to respond differently to the same radiant microwave energy environment.

Detecting Your Level of Hydration

HydroSmart is a new way to determine if you are adequately hydrated at any given time. It is a handheld, portable, simple- to-use device that requires a stream of urine, and the results are given almost instantaneously via a color-changing reagent. A color change corresponds to the specific gravity of the urine specimen. Urine specific is a measure of a person’s level of hydration. The device avoids the need to urinate into a plastic cup, which is normally delivered to another person for lab analysis; a situation that is somewhat embarrassing and most importantly, time-consuming. The reagent is bromthymol blue, poly(methylvinyl ether/maleic anhydride) and an alkaline compound such as sodium hydroxide. It is absorbed on a porous membrane, such as a woven matrix of cellulosic fibers or other substrate material, which can retain the reagent. There is a cap that contains a color chart for comparison with the color resulting from the reaction of the urine and the chemical reagent.
