Antioxidant Activity of Gamma-Irradiated Asparagus cochinchinensis (Asparagi radix) (Lour.) Merr. Extract and Inhibition Effect on Lipid Oxidation of Emulsion-Type Pork Sausage

Abstract

The objective of this study was to determine the antioxidant activity of gamma- irradiated Asparagus cochinchinensis (Asparagi radix) (Lour.) Merr. Extract (ARE) and its inhibition effect on food lipid oxidation using emulsion-type pork sausage as a model. ARE was prepared from dried Asparagi radix root and ARE solution (1.0 g/mL) was gamma-irradiated with designated doses at 5, 10, and 20 kGy. Antioxidant activity of ARE solution was determined by measuring 1,1-diphenyl-e-picrylhydrazyl (DPPH) and 2,2'-azino-bis (3-ethylbenzothiazoline-9-sulphonic acid) (ABTS) radicals. Activities of DPPH and ABTS radicals were decreased, whereas total phenolic contents increased after gamma irradiation with a dose dependence. Addition of gamma-irradiated ARE dose-dependently retarded lipid oxidation of emulsion-type pork sausage during storage at 4℃. These results indicated that gamma-irradiated ARE might have antioxidant activity more than non-irradiated ARE due to increase of the content of polyphenolic compounds by ionizing radiation.

“…Merr., which is one of the authentic herbal medicine in Guizhou (China). According to modern studies, it has anti-tumor (Zhang et al, 2021), anti-aging (Cho & Yang, 2018), anti-inflammatory (Lee et al, 2009; Samad et al, 2014) and immune regulation (Chen et al, 2011; Tang, 2014) for widespread using in bronchitis, pulmonary disease, and diabetes (Sung et al, 2017). According to the 2020 edition of Chinese Pharmacopoeia (Ch.P), the origin processing and the processing process of AR are disconnected from each other, which not only increases the production cost of AR processing but also leads to the loss of active ingredients.…”

“…In traditional Chinese medicine, Asparagus cochinchinensis is used to nourish yin and moisten dryness. Modern research shows that Asparagus extract pregnane glycosides and polysaccharides have anti‐oxidant and anti‐neuroinflammatory properties (Cho & Yang, 2018; Jian et al, 2013). Panax notoginseng is a type of precious Chinese medicine, and it is primarily composed of polysaccharides and saponins.…”
