Microencapsulation of Horseradish (Armoracia rusticana L.) Juice Using Spray-Drying

Abstract

Horseradish contains many bioactive compounds with antioxidant activity. The current study aimed to evaluate the effect of various wall materials and their ratios on the physical properties and bioactive-compound retention and stability in microencapsulated horseradish leaf and root juices. Horseradish juice was microencapsulated using maltodextrin, maltodextrin/gum Arabic, soy protein isolate, and starch with three different core-to-wall ratios. The total phenolic, total flavonoid, total flavan-3-ol, and total phenolic-acid contents, as well as antioxidant activity, were determined using spectrophotometric methods, whereas individual phenol profiles were determined by high-performance liquid chromatography (HPLC). Multivariate analysis of variance showed that plant material, wall material, and core-to-wall ratio had a significant effect on the bioactive-compound retention and antioxidant-activity preservation. Microcapsules produced from horseradish leaf juice had a significantly higher content of phenolic compounds and antioxidant activity compared to root-juice microcapsules. However, better retention was observed for microencapsulated horseradish root juice. Maltodextrin and maltodextrin/gum Arabic were the most effective wall materials for the retention of bioactive compounds, while they also had a smaller particle size and better solubility. The horseradish-juice microcapsules possess a high content of rutin. The highest stability of bioactive compounds after storage was found at a core-to-wall ratio of 20:80.

Microencapsulated pomegranate peel extract induces mitochondrial complex IV activity and prevents mitochondrial cristae alteration in brown adipose tissue in mice fed on a high-fat diet

“…This fact could be explained by the type and concentration of the wall material that influenced core material volatility throughout crust formation during drying and, therefore, retention of the active compounds within the microparticle (48) . However, TP retention, defined as a relation between the amount of active compounds in microparticles and the active compound in the infeed solution (49) , was 77•8 % (data not shown). These TP losses could be explained by the quick contact of polyphenols with hot air and oxygen during crust formation (19) .…”

Assessment of antioxidant and antimicrobial activities of Crambe spp. during vegetation

“…& Scherb.). This is a well-known species with a rich content of biologically active compounds (Agneta et al, 2013;Tomsone et al, 2020). It is a well-known plant with biological activities such as antioxidant (Calabrone et al, 2015;Ivanišová et al, 2020), and antimicrobial ones (Park et al, 2013) that is also widely used as a food plant with a pungent smell, intense lachrymatory odor and bitter taste (Rivelli et al, 2017).…”
