The purpose of this study is to address consumer’s preference of natural pigments over synthetic ones and their use in various product developments rather than using synthetic colours. A budding interest of using natural pigments has made researchers to explore several techniques for their stabilization and application in different food products.

In this review, four major natural pigments with potential health benefits have been studied. Betalins, carotenoids, anthocyanins and chlorophylls, in spite of having excellent bio-functional and therapeutic profile, are found to be unstable. Therefore, various nanoencapsulation techniques are used to increase their stability along with their therapeutic properties.

Nanoencapsulation of natural pigments improves their stability, their effect on therapeutic properties and their application in different food products. These findings could be attributed to the encapsulating material as it acts as a barrier and ushers changes in the matrix of natural pigments. Also, nanoencapsulation not only increases stability but also provides several health benefits such as anti-inflammation, anti-cancer, anti-allergic and anti-thrombotic properties.

This paper highlights the openings for the use of nanoencapsulation of natural pigments to stabilize them and use them as a potential colourant and functional ingredient in different food products. Phenols, carotenoids and antioxidant activity are the major factors that are responsible for promoting several health benefits.

The main purpose of this research is to empirically test the impacts of emotional intelligence score and emotional intelligence processing on the performance of investor’s portfolio.

A mail questionnaire survey was conducted on a sample of 983 international investors. The total number of usable responses received was 197 giving a response rate of 20.4 per cent. From 197 investors, 46 accepted to complete the experiment study during two trading hours for each investor from January first until February 19, 2015.

The results reveal a positive impact of emotional intelligence on portfolio performance. Additional analysis shows that the emotional intelligence process has a significant impact on the portfolio performance. The higher impact is revealed when the investors understand the markets tendency, manage their own emotions, take their financial decisions and finally control their personnel emotions during market fluctuations. The lower impact is detected when investors take reactive decisions after perceiving the markets tendency. This research also reveals that the investors have high capacity to manage and control their emotions during market fluctuations especially who are characterized by high emotional intelligence level.

The first limit of this research is the exploration of limited number of investors and financial operations during limited period. Therefore, the results could not be generalized, and further studies should include larger samples during larger period. The second limitation concerns the used variables to measure the portfolio performance and the emotional intelligence level. For future studies, it will be preferred to use other quantitative and qualitative variables lead to measure the different analytical dimensions of portfolio performance and emotional intelligence.

The results hold implications for investors that seek to enhance efficiently and effectively the portfolio performance. It also prompts investors to focus on effort that can improve the management and the control of personnel emotions.

This paper presents one of the first empirical studies that attempt to explore how emotional intelligence and, particularly, emotional process serve to sustain the performance of portfolio during market fluctuations.
