Analytical procedures for determination of phenolics active herbal ingredients in fortified functional foods: an overview

Abstract: Fortification of foods with phenolic compounds is becoming increasingly popular due to their beneficial physiological effects. The biological activities reported include antioxidant, anticancer, antidiabetic, anti-inflammatory, or neuroprotective effects. However, the analysis of polyphenols in functional food matrices is a difficult task because of the complexity of the matrix. The main challenge is that polyphenols can interact with other food components, such as carbohydrates, proteins, or lipids. The chemi… Show more

“…These compounds are present in plants in the free form and as ester and/or glycosidic derivatives. However, the health effects of bioactive polyphenols are determined by their bioavailability which is influenced by many factors, including phenolic structure, chemical interactions, food processing and the food matrix components [ 12 , 13 ]. There is also no information about free and conjugated phenolic compounds in different herbs.…”

“…In light of these shortcomings, high-performance liquid chromatography (HPLC) coupled with diode array detection (DAD) appears to be the most commonly employed technique for the qualitative and quantitative analyses of phenolic compounds [ 1 , 8 , 16 , 58 ]. Although the set up of HPLC–DAD is relatively cheap and the analysis robust, the method nonetheless faces several disadvantages, such as i) compound identification is only based on retention times and associated UV spectra, which might not allow us to sufficiently discriminate between compounds of a very similar chemical nature, and ii) low detection and quantification limits when analysing complex matrices [ 59 ].…”

“…The popularity of this assay can mainly be attributed to its simplicity and speed of analysis, but it presents low specificity, as the color reaction can occur with any oxidizable phenolic hydroxy group, especially if they are present in large amounts [ 88 ]. In fact, other substances such as ascorbic acid, aromatic amines, reducing sugars, SO 2 , tyrosine [ 84 , 89 ], vitamins, amino acids, proteins, organic acids [ 90 ], and the presence of Fe(III) [ 86 ] interfere with the results of the Folin–Ciocalteu assay and they are inadvertently quantified as polyphenols, skewing the results. However, this method continues to be widely applied in food and plant science to measure total phenolics due to its ease of use and low cost.…”
