Effects of different pretreatments on the physicochemical characteristics and quality criteria of chestnut ( Castanea sativa Mill.) pickle: A new value‐added product

Abstract

Chestnut is a fruit mainly consumed in the fresh form with the preferred cooking methods like boiling or roasting then peeling the shell and consuming the nutmeat (Mert & Ertürk, 2017). In addition, fresh chestnuts can be chilled then used up in all seasons. Furthermore, the food industry uses many techniques to process chestnuts, and the confectionery method is the most widely applied one as well as chestnut flakes, chestnut puree, cream, and flour products (Piccolo et al., 2020;Sacchetti et al., 2005;Zhu, 2016). In candied chestnut production, small size fruits are removed from the processing line as they are not suitable for production. At this point, pickling appears to be a promising processing technique to increase its added value for small-size chestnuts.Turkey is one of the main substantial centers for chesnut production and is an important country for both horticulture and chestnut

Sweet Chestnut (Castanea sativa Mill.) Nutritional and Phenolic Composition Interactions with Chestnut Flavor Physiology

“…On the other hand, it is a rich source of starch (carbohydrates), protein, dietary fiber, vitamins, minerals (such as potassium, phosphorous, and magnesium), lipids, and nutrients. Furthermore, it is a good source of antioxidants such as L -ascorbic acid, carotenoids, and phenolic compounds such as gallic and ellagic acids [ 2 , 15 , 16 , 17 , 18 , 19 ]. Due to the mentioned characteristics, the chestnut may have beneficial health effects, arousing consumer interest.…”

“…In addition to the fat properties, the chestnut also contains natural phenols and flavonoids with antioxidant activity to prevent cardiovascular disease. These components are essential in preventing diabetes and several types of cancers [ 4 , 15 ]. Regarding digestive health, nuts reduce cholesterol levels and stabilize blood sugar levels.…”

“…Vitamins are essential for a balanced and healthy diet. Chestnuts contain fat-soluble vitamins (Ascorbic acid, B1, B2, B3, B6, and E) which promote healthy skin and improve brain function [ 15 , 33 ]. They play a key role in the aging process, help prevent blood clotting, are gluten-free, and are of great benefit to patients with celiac disease [ 4 , 34 , 35 ].…”

“…They play a key role in the aging process, help prevent blood clotting, are gluten-free, and are of great benefit to patients with celiac disease [ 4 , 34 , 35 ]. In addition, they also contain vitamin C (ascorbic acid) [ 15 , 32 ], which is an important antioxidant for human colon cells [ 36 ]. The intake of minerals is equally crucial for the proper functioning of the human body.…”

“…Chestnut ( C. sativa ) is an important resource in Europe due to its economic value associated with fruit, wood, and tannin production, and indirectly with honey production, but also due to its cultural value [ 4 ]. Even more, the chestnut tree is known as “tree bread” since its nuts, with elliptical shape, bright reddish-brown color with long dark lines, and intense flavor [ 7 ], contain essential nutrients in the human diet, such as starch, sugar, and protein [ 15 ].…”
