Antioxidant Activity of Artisanal Honey From Tabasco, Mexico

Abstract

Potential claims for honey, floral variety and their health properties are relevant for small farmers and artisan producers. The antioxidant activity of honey samples from cacao farms, mangrove, citrus, and coconut groves from Mexico was established by applying a multiplemethod approach, which included determination of the level of total phenolic compounds and total flavonoids. Total phenolics and total flavonoids ranged from 51 to 134 mg gallic acid equivalents (GAE)/100 g honey and from 29.6 to 187.1 mg rutin equivalents/100 g honey respectively. Methanolic and aqueous solutions had similar profiles for inhibition of 2,2'-diphenyl-1-picrylhydrazyl (DPPH) radical (range from 33 to 85%) but the aqueous solutions tended to show lower radical scavenging properties. Linear correlations were established between flavonoids contents and percentage inhibition of DPPH, but phenolics contents were not well correlated (R 2 = 0.68) to the ferric reducing antioxidant power (FRAP) values which showed wide ranges from 48 to 152 mg Trolox/100 g honey. No patterns could be found in relation to antioxidant activities and the agrifood system of origin, floral availability, collection location, or season. Artisan honey samples from Tabasco were highly variable in their antioxidant properties, possibly because of the biodiversity and seasonal variations, which contribute to their unique nature. The antioxidant tests used in this study could be useful to verify the antioxidant function of honey.

Antioxidant Activity, Total Phenolic Content, Individual Phenolics and Physicochemical Parameters Suitability for Romanian Honey Authentication

“…DPPH radical scavenging activity is a parameter that varied significantly (p < 0.001) depending on the botanical origin of the honey samples analyzed. By comparison to the antioxidant activities reported for honey samples from other geographical regions, which include studies by Ruiz-Navajas et al [70] who reported values of 33.4-85.5% for honey from Tabasco (Mexico) and Baltrusaityte et al [71] who reported for honey from Lithuania values between 31.1% and 86.9%, Romanian honey had overall higher antioxidant activities.…”

Phytochemical analysis and antioxidant activities of Lantana camara and Lantana montevidensis extracts

“…These bioactive compounds are able to act as reducing agents, free radical scavengers, metal chelators or deactivators of singlet oxygen and/or display simultaneously more than one of these functions (Gramza et al, 2004). Its antioxidant properties also interfere with oxidative reactions of chain propagation (Ruiz-Navajas et al, 2011). Table 1 shows the concentrations of flavonoids and phenolic compounds found in the ethanol extracts.…”

Antioxidant Capacity and Total Phenolic Content in Honey Brands from Mexican Market and Some Physicochemical Parameters Related

“…However, some samples of fresh honey have similar levels of antioxidant capacity to the values found in this work. For example, it has been reported values between 33.4 and 85.5% for honeys from Tabasco (México) [16] and in honeys from Lithuania values between 31.1 and 86.9% in DPPH reaction system [35].…”

“…Honey from Mexico enjoys the preference of consumers around of the world due to its good sensory and nutritional properties. Several studies have reported the physicochemical properties and the antioxidant capacity of different types of artisanal or fresh honeys from México [13][14][15][16]. In the Mexican market it is also possible to purchase different honey brands, which normally are subject to an industrial packaging process that includes heating and filtering.…”
