Food & Wine Analysis

Process control during production is an important consideration for the food, wine and beverage industry. This ensures cost effective production of high quality products, within current legislative regulations.

Randox Food Diagnostics offers a versatile range of kits for analysis of food, wine and beverage products. These enable rapid and frequent monitoring of the production process and quality control of raw materials and finished products.

The manufacturing of all kits conforms to a Quality System, which satisfies the requirements of ISO 13485:2003 and the Quality System Regulation as set out in Part 820 of Title 21 of the Code of Federal Regulations.

Features of Randox Food Diagnostics test kitsFood & wine analysis• Few components for ease-of-use

and rapid handling• Extended linearity for minimal

sample dilution• Extended stability ensures less

wastage• Applications for most manual, semi-

automated and automated analysers• Beverage products can be analysed

directly without pre-treatment.

Ethanol or ethyl–alcohol is the most common organic alcohol. It is widespread in its natural form and thus quantitative determination is not only important in alcoholic beverages but also in non alcoholic beverages and foods. Ethanol is produced by yeast during yeast fermentation. Ethanol determination in wine is critically important as not only does it influence taste and aroma but also the rate of taxation. The Randox Food Diagnostic ethanol assay kit provides a simple, rapid and sensitive enzymatic method for the accurate quantification of ethanol concentration in wine.

Ethanol

Lactic acid is a weak acid produced during the secondary fermentation of malic acid. It is added as a preservative in a diverse range of food products including baby food, beer, dairy products, meats, sugar production, animal feed and tobacco. Lactic levels increase during beverage fermentation.

• Suitable for manual use or for automation on a range of analysers

• Lyophilised kit stable to expiry

Lactic acid

Acetic acid is the most common of the volatile acids. Small but measurable quantities of acetic acid are formed during normal bacteria free alcoholic fermentation. Wines with high levels of acetic acid indicate spoilage organisms (Acetobacter) are present. Acetic acid is found in most food stuffs and is involved in the metabolic processes during the ripening of fruit.

Acetic acid

Nitrogen compounds are of extreme importance in yeast growth. Ammonia is present in musts and to a lesser extent in wines. Yeast rapidly depletes the free ammonia as an easily assimilated nitrogen source.

Ammonia

Key Features • Working reagent stable for three weeks at +2 - +8oC


• Suitable for manual use or for automation on arrange of analysers


Sugars play a key role in the wine making process. Glucose and fructose are found in honey, sweet fruits and vegetables. Fructose is sweeter than glucose and is used in the production of many diet foods. Glucose with fructose is one of the two principle sugars of sweet wines and is an important indicator of grape ripening. Glucose is high during ripening and fructose is high in over ripe grapes. Two in one kit: the dual kit enables the determination of both glucose and fructose and their combined total sugar concentration.

UV method Cat No.: GF2635Number of tests: 100

Antioxidants present in red wine, tea and other beverages have been shown to give a cardio-protective effect. The compounds in beverages, which contribute to this effect are Phenolics, of which Polymeric Phenols are the largest subgroup. Phenolics also contribute towards the taste, colour, odour and preservative of the beverage. This Total Antioxidant Status (TAS) kit offers a cost effective and convenient assessment of a beverage’s phenolic content by way of antioxidant activity. The kit provides a means of assessment of the overall antioxidant protection afforded by the individual sample and can help manufacturers evaluate the impact of various practices on the TAS levels.

Colorimetric methodCat No.: NX2332. Number of tests: 50

TAS Control Cat. No. NX2331 Size 10x5 mls. TAS Standard Cat. No. NX2615 Size 10x1 mls

Research has indicated that levels of TAS are highest in red wine followed by tea, whilst many other beverages also contain antioxidants at significant levels such as cranberry juice, apple juice and coffee. The TAS kit is a unique patented screening test and the only commercially available test on the market in complete kit format which measures the Total Antioxidant Status in the sample. Results can aid manufacturers in evaluating the effects of different production practises on the TAS levels. Actual TAS results obtained from the kit can be useful in marketing terms.

Key Features • Linearity of 2.5 mmol/L

• Rapid analysis time




TAS kit

Malic acid is measured in order to monitor malolactic fermentation which softens the flavour of wine and increases its microbial stability. During malolactic fermentation L-Malic acid levels decrease and in final stages of ripening malic acid decomposes and the grape can become over ripe. Malic acid is used in the wine industry to determine the ripeness and variety of grapes.

UV method Cat No.: ML2634Number of tests: Manual 40, RX monza 80

Malic acid

Key Features • Extended linearity of 1.0 g/l


• Three weeks working reagent stability at +2 - +8oC

• Good precision: CV 3.6% at <0.02 g/l (n=15)




Potassium is the primary cation present in grape tissue. Potassium moves into cells in exchange for hydrogen ions from organic acids. Crushing, skin contact and pressing all influence potassium levels. Potassium is a critical factor in acid salt formation and tartrate precipitation. Excessive potassium contributes to higher pH in wines and potential tartrate instability problems.
