Background. Some of the factors determining the nutritive value of asparagus include its low energy value, high contents of dietary fibre, vitamins and minerals, as well as contents of antioxidants. Among polyphenols rutin, quercetin, isoquercetin and kaempferol predominate, while among phenolic acids large amounts of caffeic, chlorogenic, p-coumaric, cinnamic, ferulic and salicylic acids are found in asparagus. On the Polish market there is a limited number of products based on or containing some proportion of asparagus. In view of the dynamically developing market for products with programmed health-promoting properties and the small range of foodstuffs based on asparagus the aim of this study was to develop the technology for a novel meat product using freee-dried green asparagus.
Material and methods. Green asparagus cv. ‘Grolim’ was obtained from the plantations in Miedzichowo, the Nowy Tomyśl county (harvest of 2014). Cooked asparagus spears were comminuted and freee-dried. Meatloaf variants were prepared with a 1.5%, 2% and 3% asparagus addition. The chemical composition and total polyphenol contents were assayed. Antioxidant activity was determined in DPPH and ABTS tests. Chelating activity was recorded and sensory evaluation was performed.
Results. It was shown that the addition of asparagus had a positive effect on the antioxidant activity of the product. Meatloaf with the addition of asparagus had higher polyphenol contents and as a result – also higher scavenging capacity towards the DPPH radical and the ABTS cation radical, as well as chelating activity. Based on the results of sensory evaluation it was stated that a 1.5 and 2% addition of asparagus provides a product with desirable sensory attributes and high scores for taste, aroma and colour.
Conclusions. The use of asparagus to produce meatloaf provides a novel meat product of high nutritive value, antioxidant activity and sensory attractiveness.
