The changes of physicochemical properties, antioxidants, organic, and key volatile compounds associated with the flavor of peach (Prunus cerasus L. Batsch) vinegar during the fermentation process.

Peach is a delicious food preferred by consumers and widely used in the manufacture of peach juice, peach juice concentrate, peach jam, dried fruit, puree, etc. Alternatively, peach can be used in the production of vinegar. In this study, peach vinegar was produced as an alternative to other industrial products produced from peach.

Volatile aroma compounds and bioactive compounds of hawthorn vinegar produced from hawthorn fruit (Crataegus tanacetifolia (lam.) pers.).

This study was aimed to produce of hawthorn vinegar to increase the usage area and consumability of the hawthorn fruit and benefit from its functional properties, and to reveal some bioactive compounds, occurred during vinegar production, the functional properties and the volatile compounds (VC). The results showed that the gallic acid was a prominent phenolic substance in both wine and vinegar, followed by the chlorogenic acid. The prominent VACs of the hawthorn vinegar were acetic acid, phenylacetic acid, acetoin, then, respectively, pentanoic acid, benzoic acid, (E)-isoeugenol, 2-cyclohexenone, propanoic acid, chavicol, and diethyl succinate.

Sour cherry (Prunus cerasus L.) vinegars produced from fresh fruit or juice concentrate: Bioactive compounds, volatile aroma compounds and antioxidant capacities.

In this study, it was aimed to determine the bioactive compounds and volatile aroma compounds of the sour cherry vinegar, and to investigate the usability of concentrated juice instead of the fresh fruit juice in vinegar production. And, two sour cherry vinegars were produced using juices prepareted fresh fruit (FSCJ) and concentrate juice (CSCJ), analyzed for functional and organoleptic aspects. The finding shown that both vinegars produced have rich functional compounds (gallic and chlorogenic acids) and volatile aroma compounds, and sour cherry is ideal for vinegar production.

Bioactive components of L. black gold (red cherry) and L. stark gold (white cherry) juices, wines and vinegars.

Cherries are one of the most popular fruits, characterized by attractive colour, firmness, appearance and delicious tastes. Cherries are consumed fresh as well as in jams, wine, dried, candy and other processed products. Cherries vary in antioxidant properties and phenolic substances.

Bioactive components of mother vinegar.

Objective: Mother vinegar is extracellular cellulose and is a thick, hard layer formed by the acetic acid bacteria on the surface of vinegar. The aim of the study was to determine the bioactive components of mother vinegar produced from various vinegars.

Methods: Mothers of vinegar were produced during vinegar productions using surface culture method from apple and pomegranate juices.

Functional properties of vinegar.

A variety of natural vinegar products are found in civilizations around the world. A review of research on these fermented products indicates numerous reports of health benefits derived by consumption of vinegar components. Therapeutic effects of vinegar arising from consuming the inherent bioactive components including acetic acid, gallic acid, catechin, ephicatechin, chlorogenic acid, caffeic acid, p-coumaric acid, and ferulic acid cause antioxidative, antidiabetic, antimicrobial, antitumor, antiobesity, antihypertensive, and cholesterol-lowering responses.

Effects of apple cider vinegars produced with different techniques on blood lipids in high-cholesterol-fed rats.

Red delicious apples were used to produce natural apple cider with and without inclusion of maceration. Traditional surface and industrial submersion methods were then applied to make vinegar from apple ciders. Apple cider vinegar samples produced with inclusion of maceration in the surface method had the highest total phenolic content, chlorogenic acid, ORAC, and TEAC levels.
