Curcuminoid content and antioxidant activity in spray dried microparticles containing turmeric extract

Starch is widely consumed by humans as an inexpensive and stable available carbohydrate source, and much work has been performed on the structure, functionality and applicability of starches. Although conventional sources of starch, such as corn and potato, other sources with improved properties are becoming significant to allow simpler and more robust processes. The feasibility of the use of new starches, i.e., legume, seed and palm, as renewable materials for commercial application may provide cost reduction of raw material in industries. Little information is available on the structure, properties and practical applicability of non-conventional sources of starch. Thus, it is necessary that these starches be studied to obtain and report their structural parameters, information that is required to gain competitiveness in an international-scale industry. A review of properties, applications, future trends and perspectives of some new starches is presented in this review.

Abstract. Recently, ultrasound assisted supercritical fluid is used for extraction the valuable compounds from a number of plant materials as an alternative to conventional method because it can enhance the extraction rate and yield. Curcumin is an important component of turmeric (Curcuma longa L.) with many useful functions to human health. The objective of this study is using ultrasonic assisted supercritical carbon dioxide (USC-CO2) to extract curcumin from turmeric and compared to conventional method. The effect of operating conditions on extraction, including temperature (40-60 o C), pressure (15-25 MPa), extraction time (30-120 min), CO2 flow rate (2-4 mL/min) and percentage of cosolvent (10-20% v/v) were also studied. The result shows that the high extraction yield of 7.17% w/w and curcumin content of 1.69% w/w were achieved at temperature of 50 o C, pressure of 25 MPa, extraction time of 90 min, CO2 flow rate of 3 mL/min with 10% cosolvent. Compared to conventional method, USC-CO2 could provide higher curcumin content in extraction yield in a shorter extraction time. Scanning electron microscopy (SEM), thermal gravity (TG), and fourier transform infrared spectroscopy (FTIR) was used to analyse turmeric undergoing USC-CO2 and conventional extraction and showed that ultrasound could break down the cell walls and remove some functional groups from plant materials, resulting an increase the selectivity of compounds in extraction yield.

Curcumin yellow dye is considered as an antioxidant, susceptible to light and oxidative degradation. Microencapsulation improves its stability and facilitates its use. This work aimed to investigate the effects of different formulation wall materials (gum arabic, a binary mixture of maltodextrin and modified starch, and a ternary mixture of gum arabic, maltodextrin and modified starch) and different drying methods (for spray and lyophilization) on the stability of microcapsules of turmeric oleoresin. The drying method affected retention curcumin powder in the drying process and storage of the microcapsules under incident light. Curcumin retention during lyophilization was greater than spray drying, but showed the opposite behavior during storage; spray-dried capsules had a higher retention of curcumin after 8 weeks under light exposure. As a result, the ternary mixture of gum arabic, modified starch and maltodextrin was more effective to prevent loss of curcumin and color changes in the microcapsules. PRACTICAL APPLICATIONSThe main function of turmeric oleoresin is to give color and tempered aroma in certain foods such as pickles and mustard. The knowledge of encapsulation techniques allows the control of the bioactive components, the release time and dosage of turmeric oleoresin in the structure of the food. Moreover, the encapsulation of oleoresin helps to reduce oxidation process by exposure to the environment, increasing the shelf life and the solubility. The results of analysis of this work lead to the use of bioactive components for implementation in similar products, thereby improving their stability.
