摘要

Giloy (Tinospora cordifolia Miers.)是一种著名的草药植物,具有丰富的次生代谢物治疗性,但味道较苦,因此限制了其作为功能性食品的潜力。因此,本研究旨在通过冷等离子体(CP) (10-30 kV, 10-40 min, CCD有5个中心点)和微波(MW) (100-180 W, 5 - 15 min)的应用来降低giloy汁的苦味,使其以更美味的形式出现,这是一种非常好的方法,不同于现有的脱臭方法,如超声波和β-环糊精掺入方法。双环二萜是甘露中主要的致苦元素;因此,以总萜含量(TTC)作为衡量苦味的衡量因素,同时通过FRAP、TPC、TFC和DPPH自由基清除活性测定,针对高浓度的各种生物活性化合物(bc)。RSM用于解决影响因素方面bc含量的变化。在30 kV的CP处理25分钟后,观察到giloy汁的TTC下降了73%,而在100 W的MW处理15分钟后,TTC下降了26.5%,FTIR结果也证实了这一点。样品的物理表面形貌受到CP和MW处理的影响,正如SEM图像所证明的那样,这有助于bc的蒸发和扩散,并进一步改变其功能,这是由于操作条件的影响。CP对TTC的还原效果较好,而MW对萜类化合物的提取效果较好。

Microwave and atmospheric cold plasma aided debittering of giloy (Tinospora cordifolia Miers.) juice: Effect on bioactive compound content

Giloy (Tinospora cordifolia Miers.) is a well-known herbal medicinal plant that is therapeutically rich in secondary metabolites but is bitter in taste, thereby limiting its potential to be used as a functional food. Hence, this study was aimed at reducing the bitterness of giloy juice through cold plasma (CP) (10–30 kV, 10–40 min, CCD with 5 center points) and microwave (MW) (100–180 W, 5–15 min) applications, making it available in a more palatable form, which is quite a noble approach unlike already existing debittering methods like ultrasound and β-cyclodextrin incorporation methods. Bicyclic diterpenoids are the principal bitterness-causing element in giloy; hence, total terpenoid content (TTC) was taken as the gauging factor to scale the bitterness while targeting higher concentrations of various bioactive compounds (BCs) through FRAP, TPC, TFC, and DPPH radical scavenging activity assays. RSM is used to address the change in BCs’ content with respect to the influencing factors. A decrease in TTC in giloy juice was observed by 73% after a CP treatment of 30 kV for 25 min and by 26.5% in a MW treatment of 100 W for 15, which the FTIR results also corroborate. The physical surface morphology of the sample was found to be affected by the CP and MW treatments, as evidenced by the SEM images, which aided in the evaporation and diffusion of BCs and further variations in their functionality owing to the operating conditions. CP though was effective in reducing the TTC but MW was good at extracting terpenoids along with other BCs.
