The invention seeks to improve the taking of physical measurements on an industrial product represented by organoleptic perceptions, the method providing a measurement interface that submits descriptors in a relative arrangement such that testers are not influenced by the order in which they appear, regardless of the descriptor and regardless of the field of the descriptor. For this purpose, the invention provides a method of analyzing industrial products in order to characterize them, in order to distinguish between them, and / or in order to modify them so as to improve them, by analyzing the responses of a panel of testers in application of certain descriptors. The method comprises steps consisting in selecting descriptors that are a priori pertinent for determining the organoleptic characteristics of the products; selecting a response mode; providing all of the descriptors simultaneously to the panel of testers on a single occasion and for a determined duration in a measurement interface presenting a center and an input zone for each descriptor, the input zones being distributed uniformly over at least a section of at least one conic about the center of the interface; collecting the responses from each tester as a function of the selected response mode; recording the responses; and analyzing the responses using at least one statistical method.

Disclosed is a method for the real time measurement of acrylamide in a food product. Wavelength emission data is collected from a food product. The same food product is tested off-line in an analytical laboratory for levels of acrylamide pre-cursors or acrylamide. The wavelength emission data is then correlated with the off-line laboratory data.

A drinking straw incorporates a sugar indicator section. When the straw is inserted into the drink, the indicator section changes color upon detection of sugar in the drink. This enables rapid and accurate detection of sugar in the drink. The sugar indicator straw may instead be formed as a drinking straw insert. The insert incorporates a "sleeve" through which a straw may be inserted. Then, when the straw is inserted into the drink, the insert changes color upon detection of sugar. The insert may then be disposed of. Further, the indicator may be incorporated in a drinking cup, preferably of the disposable kind. A section of the cup's wall is made porous, and the indicator is provided over the porous part. When liquid passes through the porous part, the indicator changes color if the liquid contains sugar.

Methods and apparatuses for determining entrained and / or dissolved gas content of gas-liquid mixtures. Data generated is used to control the True (air-free) or Apparent (air-containing) Density or Entrained Air content of liquids within optimum ranges, e.g. in paper coating processes and in the manufacture of food products, personal care products, pharmaceutical products, paints, petroleum blends, etc. For example, an indirect method of continuously determining the amount of gas entrained in a liquid, by: continuously measuring the temperature, flow rate, and apparent density of the mixture at two different pressure states, and calculating the volume percentage of the gas in the liquid by using equation (28) x⁢ ⁢%=VsVs+V(28)wherein V is the volume of the gas-free liquid calculated by equation (23) V=1ρ1-[P2P2-P1⁢(1ρ1-1ρ2)-R⁢ ⁢TP2-P1⁢g⁡(Δ⁢ ⁢PQa)](23)[0001]in which P1 and P2 are two different ambient pressures and ΔP=P2−P1, ρ1 and ρ2 are apparent densities of the liquid sample measured at P1 and P2, respectively, R is the constant of the Ideal Gas Law, T is the liquid temperature, Q is the flow rate, g(ΔP / Qa) is a function for determining the amount of gas being dissolved between P2 and P1, and Vs is determined by equation (27) Vs=TsT⁢P1⁢P2Ps⁡(P2-P1)⁢(1ρ1-1ρ2)-R⁢ ⁢TsPs⁢(P1P2-P1⁢g⁡(Δ⁢ ⁢PQa)-g⁡(P1-PsQa))(27)in which Ps and Ts are standard pressure (1 atm) and temperature (0° C.), and g⁡(P1-PsQa)is a function for determining the amount of gas being dissolved between P1 and Ps.
