Pectin is a polymer with a core of alternating α-1,4-linked d-galacturonic acid and α-1,2-l-rhamnose units, as well as a variety of neutral sugars such as arabinose, galactose, and lesser amounts of other sugars. Currently, native pectins have been compared to modified ones due to the development of natural medicines and health products. In this review, the results of a study of the bioactivity of pectic polysaccharides, including its various pharmacological applications, such as its immunoregulatory, anti-inflammatory, hypoglycemic, antibacterial, antioxidant and antitumor activities, have been summarized. The potential of pectins to contribute to the enhancement of drug delivery systems has been observed.

Biological Activity and Pharmacological Application of Pectic Polysaccharides: A Review.

Acerola (Malpighia emarginata DC.) is one of the richest natural sources of ascorbic acid and contains a plethora of phytonutrients like carotenoids phenolics, anthocyanins, and flavonoids. There is an upsurge of interest in this fruit among the scientific community and pharmaceutical companies over the last few years. The fruit contains an exorbitant amount of ascorbic acid in the range of 1500–4500 mg/100 g, which is around 50–100 times than that of orange or lemon. Having a reservoir of phytonutrients, the fruit exhibits high antioxidant capacity and several interesting biofunctional properties like skin whitening effect, anti-aging and multidrug resistant reversal activity. Countries like Brazil, realizing the potential of the fruit have started to exploit it commercially and have established a structured agro-industrial based market. In spite of possessing an enriched nutrient profile with potent “functional food” appeal, acerola is underutilized in large part of the globe and demands greater attention. A comprehensive literature analysis was carried out with reference to the latest frontiers on the compositional characteristics of the fruit. Emphasis has been given on newer dimensions of functional aspects of ascorbic acid and allied work and pectin and pectin methylesterase. The range of nutraceutical phytonutrients present in acerola and their biofunctional properties has been discussed. Recent advances in the value addition of the fruit highlighting the use of techniques like filtration, encapsulation, ultrasound, sonication, etc. are also elaborated. Furthermore, the potential use of acerola pulp in edible films and waste utilization for development of valuable byproducts has been highlighted.

Acerola, an untapped functional superfruit: a review on latest frontiers

Comparison of the antioxidant property of acerola extracts with synthetic antioxidants using an in vivo method with yeasts.

Resume de l'editeur : Wild Plants, Mushrooms and Nuts: Functional Properties and Food Applications is a compendium of current and novel research on the chemistry, biochemistry, nutritional and pharmaceutical value of traditional food products, namely wild mushrooms, plants and nuts, which are becoming more relevant in diets, and are especially useful for developing novel health foods and in modern natural food therapies. Topics covered will range from their nutritional value, chemical and biochemical characterization, to their multifunctional applications as food with beneficial effects on health, though their biological and pharmacological properties (antioxidant, antibacterial, antifungal, antitumor capacity, among others).

Wild plants, mushrooms and nuts : functional food properties and applications

Acerola is a cherry-like tropical fruit that is very popular in Central America, the Caribbean countries (especially in Barbados, Trinidad and Tobago, and Haiti), and Brazil. This fruit, which has a red color at complete maturity, is valued mostly for its vitamin C content. Recent research showed that in addition to vitamin C, acerola fruit may be a good source of phytochemicals such as anthocyanins, nonanthocyanin phenolic compounds, and dietary carotenoids. Because these compounds are known as bioactive due to their strong antioxidant capacity, acerola fruit is attracting the attention of food researchers and the exotic fruit market. One of the problems faced by acerola growers and processors is that acerola fruit is highly perishable at complete maturity, resulting in serious quality losses during and after harvest. Therefore, the harvest and the postharvest handling are very important to obtain fruits with acceptable quality. The first part of this review is a complete analysis of the available inform...

Acerola (Malpighia emarginata DC): Production, Postharvest Handling, Nutrition, and Biological Activity

Summary

The antioxidant activity and antimicrobial property of phenolic extracts from acerola (Malpighia emarginata DC) fruit were assessed. The contribution of ascorbic acid and phenolic compounds in the total antioxidant capacity of the extracts was also evaluated. The extracts showed high total phenolic values and possessed high antioxidant activity as expressed by 2,2′-diphenylpicrylhydrazyl (DPPH) and oxygen radical absorbance capacity assays (ORAC). The ascorbic acid content ranged from 405 to 1744 mg/100 g of fruit on a fresh weight basis. The antioxidant capacity of the phenolic fractions was in the following order: anthocyanins<phenolic acids<flavonoids. The phenolic fractions contributed 7.1–36.5% of the antioxidant activity expressed by ORAC, whereas the contribution of ascorbic accounted for 18–39% of the total activity. Selected extracts from the flavonoids fraction showed some activity against Staphylococcus aureus.
