Abstract

Olea europaea L. is the botanical name for olive tree; it is usually produced in the Mediterranean countries. The by-products are table olives and olive oil; they undergo many processes in order to become edible for consumers. Table olives are affected by various agronomical factors; this affects the structure of nutritional and non-nutritional components. Some of the most significant nutrients include monounsaturated fatty acids (MUFAs), vitamin E and a substantial amount of phytochemicals. The primary aim of this review is to study the various bioactive compounds found in the table olives, it also comprehensively explained the numerous health benefits associated with the regular intake of olive oil.

Introduction

The botanical name of the evergreen olive tree is Olea europaea L., it is usually consumed by the Mediterranean countries, the fruit is known as the olive and the derivatives are table olives and olive oil (Foscolou et al., 2018). According to the International Olive Council, almost 6000 years ago there are some records that show the first cultivated trees i.e. olive tree can be found in Asia Minor regions (Román et al., 2019). Nearly in all regions of the continents there is widespread olive trees plantation, however, the countries which hold its majority of the production are Mediterranean countries including Spain, Italy, and Greece (Rossi, 2017). There are other important producing countries also including Egypt, Turkey, Syria, and Morocco (IOC, 2019). Nonetheless, the worldwide olive production is from the European Union, thus the production value is around 7000 million euros annually and consequently becoming a major constituent for both industrial and agricultural sectors (Rossi, 2017). 

There are three basic parts of the olive fruit namely epicarp, mesocarp, and the endocarp (Ghanbari et al., 2012; Bianchi et al., 2003). Collectively, the epicarp and the mesocarp form the edible part of the olive fruit (Bianchi, 2003; Lanza, 2005). Nevertheless, in order to find out the nutritional and non-nutritional composition of the table olives various qualitative and quantitative methods are employed (Ghanbari et al., 2012; Pereira et al., 2012). There is a potential increase in the concentration of oleuropein which is a glycosylated secoiridoid as the olive fruit approaches its growth phase (Ghanbari et al., 2012; Uylaser and Yildiz, 2014). Meanwhile, there is an increase in the production of many biophenols such as hydroxytyrosol (HT) (Boskou et al., 2015).

 It is not possible to consume fresh olives because of the natural bitterness caused by oleu-ropein, a bitter glucoside. Hence, it should be removed by treating with alkaline or by brining, fermentation, and acidification, thereafter allowing it to be edible for consumers (Boskou, 2017). Table olives are packed with innumerable vitamins, fats, proteins and many other carbohydrates (Lanza, 2012). 

The purpose of the review is to determine the composition and health benefits related to the table olives, moreover, to give an overview on the functional and nutritional bioactives present in the olive fruit.

2.Types of Table Olives

There are some processing phases of the olives (Jaén Index-P.I.) as shown in Figure 1. Table olives can be divided into many types, however, globally only three practices are used for its preparation; Spanish green olives, Californian black olives and Greek black olives (Pereira et al., 2006; Uylaser and Yildiz, 2014).

2.1 Spanish green olives

Olives are treated with sodium hydroxide solution (NaOH) once they have attained the standard size, this process is also known as lye treatment (Charoenprasert and Mitchell, 2012). The oleuropein is hydrolyzed into hydroxytyrosol through this lye treatment and therefore, the remaining amount of lye is washed with water, furthermore, the olives are administered to sodium chloride solution so as to enable lactic fermentation (Charoenprasert and Mitchell, 2012; Mateus, 2016). The resultant olives are then packed in brine and to prolong its shelf-life they can be submitted to sorbic acid or its salts, additionally, these olives can also be heat-treated through pasteurization for 15 minutes at 62.4 °C (Charoenprasert and Mitchell, 2012).

2.2 Californian black olives

In this method the first and foremost step is storage of olives in brine for a period of about 2 to 6 months, furthermore, by inclusion of lactic acid and acetic acid it is kept at medium acidification with pH 4 (Pereira et al., 2006; Charoenprasert and Mitchell, 2012). Olive fruits are treated with two to five sodium hydroxide solutions and eventually this enters into the flesh (Charoenprasert and Mitchell, 2012; Marsilio, 2001). Meanwhile, the process of lye is carried out and the olives in water or a weak brine solution transform into dark coloured fruit, this change is primarily caused by oxidation and polymerization of phenolic compounds (Boskou et al., 2015; Charoenprasert and Mitchell, 2012). Lastly, these olives are preserved in a can containing saline solution, thereupon; they are given to a sterilization treatment (Charoenprasert and Mitchell, 2012).

2.3 Greek black olives

In this method olives are harvested in the last stage of maturation. When the procedure of harvesting is completed olives undergo washing and are submerged in a brine solution (Boskou et al., 2015; Charoenprasert and Mitchell, 2012). Immediately fermentation starts, this occurs mainly by yeasts, lactic acid and gram-negative bacteria. The bitterness of olives is eliminated because of the dissemination of oleuropein from the fruit to the brine and along with the acid hydrolysis of the OL (Mendes, 2012; Boskou et al., 2015; Charoenprasert and Mitchell, 2012; Mateus, 2016).(Jaén Index-P.I.) and major pre-processing operation; B: Natural sweet olives.

3.Nutritional Aspects of Table Olives

It is assumed that 100 grams of table olives can provide with 180-250 kilocalories, however, there are some expectations. Lipids are main component ranging from 6-30 g/100 g. The protein content is generally low and does not vary with olive types. The protein content ranges from 1.0 to 2.2 g/100g (Boskou, 2017).

Proteins have a very little contrition in overall nutrition of olives but these proteins include all of the essential amino acids, aspartic and glutamic acids. The carbohydrates are absent in table olives. Furthermore, olives are essentially rich in fibre, this comprise mainly of  cellulose, hemicellulose, pectin and lignin (Rocha et al., 2020).

4.Health Benefits of Olives

Olives are rich in fat, carbohydrates, minerals and vitamins. Fat is the major nutrient in the form of monounsaturated fatty acids (MUFAs). According to investigations, olives are known to provide with least possible health risks. The consumption of olive oil has been linked to these health benefits in terms of diet. In Figure 2. (Rodrigo et al., 2015) clearly demonstrates some healthy effects of olive oil. Moreover, epidemiological data shows that the different antioxidants and phenolic components present in the olive oil are responsible for some of these benefits. Surprisingly, these minor factors significantly impact on lowering the prevalence of atherosclerosis, cardiovascular disease, neurological disorders, and some cancers (Guo et al., 2018). Besides, these compound also show potential as antioxidant, anti-carcinogenic, antimicrobial, and anti-inflammatory agents (Jimenez-Lopez et al., 2020).

Figure 2. Some healthy effects of olive oil

4.1 Anti-inflammatory activity

Nowadays many non-communicable diseases are primarily caused by acute or chronic inflammation, thus, one of the types of the olive oil i.e. Extra Virgin Olive Oil or EVOO plays an important role for its beneficial anti-inflammatory properties. The patients with dysmetabolic syndrome followed virgin olive oil breakfast routine, this subsequently led to reduced levels of postprandial inflammatory response (Camargo et al., 2014).

Additionally, some inflammatory bowel diseases that cause chronic inflammation of the gastrointestinal tract including ulcerative colitis and Crohn's disease can be cured with the utilization of EVOO (Millman et al., 2021). The consumption of EVOO was also found useful against rheumatoid arthritis (Marcelino et al., 2019) and systemic lupus erythematosus or multiple sclerosis (Žugčić et al., 2019). Moreover, among all the aforementioned anti-inflammatory effects of EVOO a study shows that it has neuroprotective benefits also that may delay cognitive decline and, consequently, the onset of dementia in the elderly or Alzheimer's disease (Gavahian et al., 2019).

4.2 Antioxidant activity

(ROS) produce some highly reactive chemicals in aerobic organisms such as peroxides, superoxide and hydroxyl radical, hence, elevated levels may cause damage to DNA, lipid or proteins (Bozzetto et al., 2019). There are certain molecules known as antioxidants that prevent the action of oxidative stress primarily through a dynamic system of antioxidants, Glutathione (GSH) which are found in plants, animals, fungi and some bacteria. Reportedly only a few vitamins act as antioxidants but they present some adverse effects (Peroulis et al., 2019). Many researchers are striving hard to gather evidence apropos of the antioxidant properties of natural compounds so as to avoid any side effects. Here much importance is given to the lipophilic and hydrophilic phenols in EVOO. One of the intervention group determined that a diet enriched with EVOO was effective against HDL atheroprotective functions and oxidative status (Luisi et al., 2019).

4.3 Anti-tumoral activity

In comparison with the United States or other European countries, Mediterranean countries have historically had lower rates of some cancers, including breast, colorectal, endometrium, and prostate cancer, which have been associated with dietary factors (Klimova et al., 2019). Several studies have been conducted on EVOO's anti-tumoral and anti-cancer properties. The significant anti-cancer benefits of EVOO have been linked to breast cancer prevention. Approximately 4200 women with breast cancer were admitted in the PREDIMED trial and the women who consumed MED containing EVOO diet demonstrated minimum risk of breast cancer in contrast to women who consumed a low-fat diet (Fernandes et al., 2020). Recently, it has been proposed that epigenetic processes including miRNA and DNA methylation may be responsible for the anti-tumoral effect of EVOO, which reduces the incidence of colorectal tumours (Nanda et al., 2019).

5.Beneficial Effects of Olive Phenolic Compounds

Olive fruits and oil are a blend of variety of phenolic compounds including oleuropein, andoleocanthal, (Almatroodi et al., 2020). There are numerous hydrophilic phenolic molecules, but two in particular need to be identified: the hydroxytyrosol and the secoiridoid oleuropein. In Figure 3. (Romani et al., 2019) shows the structure of the phenolic compounds found in Olea europaea L. Generally, polyphenols are known for their biological properties. Olive polyphenols if added in a balanced diet can perform as natural anticancer agents. Research shows that polyphenols reduce the morbidity and prevent the development of many diseases like neurodegenerative and cancer diseases. In addition, these polyphenols also have other health-promoting benefits such as anti-allergic, anti-atherogenic, anti-thrombotic, and anti-mutagenic activities (Sherif et al.,

Figure 3. Structure of the phenolic compounds found in Olea europaea L.

basis prevent many diseases such as obesity, diabetes mellitus, and cardiovascular diseases. The anti-inflammatory properties of polyphenols, which are manifested by numerous pathways including antioxidant activity, are largely responsible for this beneficial effect (Bucciantini et al., 2021).  EUROLIVE study shows that polyphenols enhance the functionality of human HDL, and also favors the HDL-mediated cholesterol efflux from macrophages. In Figure 4. (Romani et al., 2019) present the benefits of EVOO. Increasing evidence suggests that EVOO polyphenols have positive effects on intestinal immunity and gut health. Furthermore, EVOO polyphenols also have antibacterial and bacteriostatic actions against pathogenic intestinal microflora (Marcelino et al., 2019).

Figure 4: Benefits of Extra-virgin olive oil

Olive polyphenols exhibit some pharmacological properties for example, hypoglycemic, anti-inflammatory, antitumoral, antiviral, and immunomodulatory activities (Fernández-Prior et al., 2021). In addition to the prevention against age-related neurodegenerative diseases, the concentration of polyphenols is affected by certain factors these comprise of olive cultivar, environmental factors, cultivation practices, and the stage of fruit ripening. The storage conditions are also very important as these conditions can alter the rate of oxidation or photo-oxidation reactions (Hornedo-Ortega et al., 2018).

6.Worldwide Distribution of Table Olives

The data of International Olive Oil Council for the year 2020/21 shows the average consumption of table olives:

•               Turkey – 13%.

•               Egypt – 12%.

•               USA – 9%.

•               Spain – 7%.

•               Algeria – 7%.

•               Italy – 5%.

•               Rest of the world – 47%

In Graph I. The International Olive Oil Council report indicates Spain as the leading country in the world for table olives production. The remaining countries such as Egypt, Turkey, Algeria, Greece, and Portugal lag behind in their performance.

Conclusion

Olive fruits are essentially valuable source of MUFA, vitamin E, and phenolic compounds. Several studies show that with the consumption of table olives the risk of chronic diseases is reduced, moreover, there is an increase in life expectancy. The most active compounds are HT and OLE. The polyphenolic compounds OL and HT present in olive oil are potent antioxidants thus, protecting against innumerable diseases including cancer, chronic inflammation and neurodegeneration. However, more extensive research is required to find out the control measures necessary for the table olives production and as a result will help to determine health benefits.
