EFFECT OF SELECTED NATURAL EXTRACTS ON ANTIOXIDANT PROPERTIES AND SENSORY QUALITY OF VARIOUS CEREAL PRODUCTS

The aim of this study was to observe antioxidant properties as well as possible changes in sensory quality of selected bakery products after their enrichment with chosen natural extracts. Four types of natural extracts in mixture with wheat flour were used in various amounts for preparation of selected bakery products (wheat bread, sweet biscuits, salty crackers, and muffins). Specifically: turmeric (Curcuma longa, L.) rhizome extract (curcumin), quercetin dihydrate extracted from the pods of Sophora japonica, L., and extracts from medicinal fungus Shiitake (Lentinula edodes) and Maitake (Grifola frondosa) were used as additions. Antioxidant properties in total antioxidant activity (TAA; using DPPH radical scavenging assay), total polyphenols content and total phenolic acids content were examined, as well as the effect of selected natural extracts on the sensory properties of bakery products (intensity of certain characteristics and overall preference). The results of antioxidant properties varied according to the used extract and its amount. Compared with control products, the TAA was significantly higher in all enriched products. While the total polyphenol content was the highest in the bread and biscuits with quercetin (20.623 mg and 18.117 mg GAE.g-1, respectively), the total phenolic acids content was the highest in those with curcumin (8.846 mg and 3.286 mg CAE.g-1, respectively). The intensity of other smell and taste of enriched bakery products influenced considerably overall acceptance, e.g. the products with quercetin associated with bitter taste were evaluated as unfavourable. On the other hand, the breads and crackers with Shiitake extract with indistinct antioxidant properties were evaluated the best, followed with curcumin and Maitake extract. Considering our overall results, we can recommend chosen non-bakery raw materials for a production of new, innovative designed cereal-based products.

The neuroprotective potential of turmeric rhizome and bitter melon on aspartame-induced spatial memory impairment in rats

Aspartame is widely used artificial sweetener. However, chronic exposure to aspartame led to spatial memory impairment and elevated oxidative stress in the brain. Extract of turmeric rhizome (Curcuma longa) (TUR) and extract of bitter melon (Momordica charantia) (BM) is known to have antioxidant activity. The present study was aimed to examine the neuroprotective potential of TUR and BM extracts, either as single or as combination, against the effects of aspartame in the brain. Here, Sprague-Dawley rats fed with aspartame (40 mg/kg BW) for 28 days were compared with rats fed with extract and aspartame. To assess neuroprotective potential, rats were given extract 7 days before and during aspartame treatment. Spatial memory was assessed with Morris water maze test followed with H&E staining of hippocampal region. Brain lipid peroxidation and enzymatic activity of malondialdehyde (MDA), glutathione peroxidase (GPx), and Acetylcholinesterase (AChE) were measured to probe status of oxidative stress in the brain. Aspartame-treated rats demonstrated spatial memory impairment and reduced number of hippocampal cells and elevated levels of MDA, downregulated activity of GPx and elevated activity of AChE. In contrast, animals received both aspartame and extract demonstrated better spatial memory function, higher number of hippocampal areas, increased GPX activity, reduced MDA levels, and decreased AChE activity were observed in the brain of extract-treated rats. Taken together, our results suggest that extract of TUR rhizome and BM fruit exhibit antioxidant activity which may contribute to the neuroprotective effects against aspartame-induced memory impairment in rats.
