Introduction
The health benefits of black aronia berry have caused renewed interest in them as a commercial super health food. The antioxidant properties of these black berries have led to research into their use as foods to contribute to prevention of diseases caused by oxidative stress, such as certain cancers, cardiovascular diseases and chronic inflammations.
Aronia Berry Products
Raw black aronia berry fruits are astringent, so the fruits are generally eaten in processed form. The berries can be canned or made into juice which can be used to make drinks and jelly. The extracts can also be used as natural colorants. As a juice product, these black berries (more commonly called chokeberry) is usually blended with other juices such as apple, black currant, cranberry and grape. It has been grown commercially in Russia since the 1940s, where it is used in juice products (mixed with apple juice), wine, and other products. It has been commercially grown in Europe in 1000s of acres where the aronia berries are used to make juice, alcoholic beverages, jams and jellies, and used as a food colorant.
In response to current worldwide human health concerns, new useful foods and healthy food products are being developed. Aronia berries are among the super fruit being processed into nectars and purees for their health benefits. It has been found that the ascorbic acid and anthocyanin levels dropped considerably during processing and also during subsequent storage, but that the new products still retained a high level of the biologically active substances found in fresh berries. Pressing the berries without heating them results in higher levels of biologically active substances. Producing aronia enriched lemon juice as a new beverage with antioxidant properties is one possible drink.
Viking and Nero are the two most popular aronia plants grown for fruit production. They were developed in Europe and are starting to become popular in the United States.
Aronia Berry Qualities
Generally, black aronia berries are high in soluble solids (12 - 20%), anthocyanins (560 - 1050 milligrams/100 grams fresh weight), have a pH of 3.3 - 3.7, and amount of alkali required to neutralize the acidic components is 0.7 - 1.2%. (This is called titratable acidity).
Anthocyanins: The pigments that cause these black berries to appear black are phenolics, primarily anthocyanins. These pigments produced mainly in the skin protect the berry pulp and seeds from exposure to ultraviolet radiation. This purple pigment is the shade that filters intense sunlight. Total anthocyanin levels in black the aronia berry have been reported to be as high as 1480 mg/100 g fresh berries. This level is among the highest measured in plants grown in North America. In addition to shielding the berries from the UV from sunlight, anthocyanins contribute to the berries' astringent taste. And, anthocyanins are antioxidants and serve to combat stress in the berries during metabolic processes. There have been no reports of side effects of eating aronia berries other than providing health benefits.
Depending on growing conditions the fruit quality can vary from one year to the next, with the anthocyanin content can differ widely from a poor production year to a good year. The anthocyanin content can increase by as much as 50% with a low fertilizer application compared to medium higher fertilizer rates.
ORAC (oxygen radical absorbance capacity) is a test that measures antioxidant strength of foods. Aronia berry is a super foods-list topper. Black aronia berry produces one of the highest ORAC values recorded, 16,062 micromoles per 100 g fresh fruit, compared to values for blueberries (highbush) which have a total ORAC score of 6,552. Acai is a berry that has been in the news, but research reveals that it takes a secondary position to Aronia berry. Acai have a total ORAC score of 5,500 ORAC and gooseberry has an ORAC score of 3277 and elderberry has a score of 14,697.
Summary
The antioxidant properties of black aronia berry fruits have stimulated research into their use as foods that contribute to prevention of diseases caused by oxidative stress, such as certain cancers, cardiovascular diseases and chronic inflammations.
