Dried Persimmon Fruit: A Year-round Available Product

Ali Sarkhosh, Fariborz Habibi, Muhammad A. Shahid, Steven A. Sargent, and Jeffrey K. Brecht

Persimmons (Diospyros kaki) are known for their sweet and flavorful taste. They are native to Asia, specifically China, and were first grown in Florida in the 1870s. Persimmons are still not as popular in the United States as other fruits, but interest has been growing in recent years. Persimmon fruit are generally classified into astringent and non-astringent types. Astringent varieties can have adverse health effects caused by tannins and must be fully ripe (soft) or artificially treated to remove astringency. Drying is a common method to preserve and extend the shelf life of persimmons while also enhancing the flavor, color, and nutritional value of persimmons. There are different methods to dry persimmons, including traditional and modern methods.

Muscadine Grape: Postharvest Physiology and Handling Practices

Fariborz Habibi, Ali Sarkhosh, and Jeffrey K. Brecht

Muscadines (Muscadinia rotundifolia Michx) are vining fruit crops native to the southeastern United States. Unlike the more common European Vitis vinifera (common grapes) and American Vitis labrusca grape species that produce berries in bunches, muscadine grapes are borne in clusters of individual, large berries. In addition to their sweetness and unique flavor, muscadines are appreciated for their high concentrations of bioactive compounds, which contribute to antioxidant activity and offer various health benefits to humans. The unique characteristics of muscadines make them valuable for both fresh consumption and processing purposes, including juice, wine, jam, and freeze-dried snacks. Proper postharvest handling ensures that muscadines maintain their nutritional value and appeal to consumers.

Alleviating Astringency in Persimmon Fruit for Enhanced Palatability and Consumer Acceptability

Ali Sarkhosh, Fariborz Habibi, and Jeffrey K. Brecht

Persimmon fruits are classified as astringent or non-astringent, depending on the level of astringency the unripe or partially ripe fruit exhibit at the time of harvest. Astringency in persimmon fruit is a sensation caused by tannins present in the flesh that can make the mouth feel dry, cause puckering, numb the tongue, and constrict the throat. Sometimes, it may also impart a bitter taste. The astringency decreases as the fruit ripen until it is no longer present in fully ripe fruit. While consumers typically prefer non-astringent varieties, the cultivation of astringent varieties notably remains common. The purpose of this publication is to introduce consumers, growers, Extension agents, and specialists to postharvest methods for reducing astringency in unripe persimmons, making them more palatable and acceptable for consumption.

Every year farmers must harvest their crops. This process marks the end of the growing season and carries social significance in communities, but it also creates challenges for producers trying to deliver fresh, high-quality produce to market. Good postharvest practices establish appropriate cold chains that maintain the correct temperatures, humidity, and respiration rates while also ensuring the safety, sanitation, and quality of the fruits. These postharvest practices differ, depending on the size and economic situation of an operation. This fact sheet provides postharvest storage, packaging, and handling recommendations for small farm specialty crop producers.
