The present disclosure provides a test strip for milk immunofluorescence assay (IFA) and use thereof, and relates to the technical field of test strip. The test strip of the present disclosure includes a sample pad, a conjugate pad, a nitrocellulose membrane, and a wicking pad assembled and pasted successively on a PVC backing card; fluorescent latex microsphere-labeled mixed antibodies are coated on the conjugate pad; anti-casein antibody (T1 line), anti-beta-lactoglobulin (BLG) antibody (T2 line), anti-alpha-lactalbumin (ALA) antibody (T3 line), anti-lactoferrin/anti-bovine serum albumin (BSA) antibody (T4 line), and rabbit anti-mouse IgG antibody (C line) are coated on the nitrocellulose membrane, where the T1, T2, T3, and T4 lines are test lines, and the C line is a control line. The test strip of the present disclosure accurately and quantitatively detects the content of casein, BLG, ALA, and lactoferrin/BSA in food, and features easy operation and high accuracy and sensitivity.

A system for analyzing a fluid includes an in-line sensor configured to analyze a fluid flowing past the in-line sensor to determine at least one in-line value of a fluid parameter of the fluid across an event period, and a sample sensor configured to analyze a sample of fluid extracted from the flow of fluid during the event period, to determine sample value of the fluid parameter for the sample. At least one processor is provided, configured to determine a representative in-line value of the fluid parameter across the event period based at least in part on the at least one in-line value, and determine an overall representative value of the fluid parameter across the event period based on the representative in-line value, the sample value for the sample, and one or more of the in-line values corresponding to the time of extracting the sample, wherein determination of the overall representative value is based on an error correction value determined for the in-line sensor during the event period.

Described herein is a system and a method to conduct for inline estimation of milk parameters such as fat, protein, lactose, somatic cell contents (SCC), and progesterone during the milking process that can be performed real time during the milking process with a commercially acceptable level of accuracy. In one example embodiment, specific wavelengths are identified that facilitate the use of low-cost Near-Infrared (NIR) Spectrometers and sensors to develop the inline, real time estimation system, with at least two segments or ranges being identified of NIR wavelengths for determining content or composition for these key parameters.

The present invention relates to a method for selecting a yoghurt sample with a creamy mouthfeel, comprising the steps of: (i) providing one or more yoghurt samples; (ii) determining from the one or more yoghurt samples the time to breakup using an extensional rheometer; and (iii) optionally, measuring the viscosity and/or shear stress of the one or more yoghurt samples; and (iv) selecting one or more yoghurt samples.

A dry stick (180a, 180b, 180c) arranged to indicate at least one biomarker value of a milk sample of an animal (100) by a lateral flow test. The dry stick (180a, 180b, 180c) includes a sample pad (310) with a reagent, configured to indicate at least one biomarker value of a received milk sample of an animal (100) by changing colours when exposed for milk having the biomarker; a porous membrane (320), configured to create a capillary flow of the milk sample, from the sample pad (310) through the porous membrane (320); an absorbent pad (330) with an absorbent configured to absorb superfluous milk from the porous membrane (320); and a porous desiccant, configured to absorb moisture from environmental air.

A flow cell with a first section and a second section, and a gasket sealing between the first and second sections. A chamber is defined in the flow cell, having a perimeter with a narrower end and a rounded wider end. An inlet passage, outlet passage, and a sensor are arranged in fluid communication with the chamber. The inlet passage directs fluid into the chamber proximal its narrow end at an angle of between about 45° and 75° relative to the plane of gasket and the outlet passage directs fluid flow out of the wider end of the chamber at an angle between about 45° and 75° relative to the plane of gasket, the inlet passage and outlet passage being angled in opposite directions. The flow cell is useful for monitoring levels of chemicals in an industrial process stream, such as lactose levels in a dairy process stream.
