Plums because of their composition, especially of dietary fibre, sorbitol and polyphenols content, have positive influence on human health. Generally growing interest in cloudy juices production due to their prevalence compared to clear ones resulted in the appearance of plum cloudy juices on the market. Cloudy plum juice may be the attractive plum product, however during juice production some pomace appears, which is discarded or used for feeding animals most of all. This by product might be a source of valuable health-promoting compounds. The aim of this work was to characterize the composition and properties of pomaces of three cultivars obtained in pilot plant scale. The influence of drying parameters and cultivar on bioactive components and antioxidant activity were measured. Plum pomaces were characterized by 38-49% of total dietary fibre in d. m., with the share of soluble fraction from 7 to 13%. Energy value was from 202 to 240 kcal 100 g(-1) d.m. Antioxidant activity was from 10 to 17.4 mikroM TEAC g(-1) d.m. Cultivar and technology of drying had significant influence on polyphenols content of investigated plum pomaces. Considering their health-beneficial components: dietary fiber and polyphenols, plum pomaces can be used for production of dietary fiber preparations.

Plums () red currants () black currants () gooseberries () sour cherries (); pumpkins ( spp.) are sources for valuable fruit- and berry-juice and cider production. This process leaves a large number of by-products (BP) in the form of pomace, which accounts for up to 80% of the raw material.

Food processing, especially the juice industry, is an important sector that generate million tons of residues every. Due to the increasing concern about waste generation and the interest in its valorization, the reutilization of by-products generated from the processing of popular fruits of the genus (rich in high-added value compounds) has gained the spotlight in the food area. This review aims to provide an overview of the high added-value compounds found in the residues of fruits (peach, nectarine, donut peach, plum, cherry, and apricot) processing and applications in the food science area.

It is estimated that more than 20% of processed apples and grapes are discarded as waste, which is dominated by pomace rich in malic acid that could be converted to high-value organic acids or other chemicals. A total of 98 yeast strains isolated from apple, grape, and plum wastes were evaluated for their ability to degrade malic acid relative to known yeast strains. Most (94%) of the new isolates degraded malic acid efficiently (> 50%) in the presence and absence of exogenous glucose, whereas only 14% of the known strains could do so, thus confirming the value of exploring (and exploiting) natural biodiversity.

The aim of this study was to assess and compare fermentation characteristics and aromatic profile of plum wines produced with indigenous microbiota and pure cultures of different selected yeast. Experiments were carried out with plum (Prunus domestica L.) varieties of different fruit ripening times (Čačanska rana, Čačanska lepotica, and Požegača).
