Trends In Maintaining Postharvest Freshness And Quality Of Rubus Berries, Hafiz Muhammad Shoaib Shah, Zora Singh, Jashanpreet Kaur, Mahmood Ul Hasan, Andrew Woodward, Eben Afrifa-Yamoah

Research outputs 2022 to 2026

Blackberries and raspberries, commonly known as Rubus berries, are commercially grown worldwide across different climates. Rubus berries contain wide array of phytochemicals, vitamins, dietary fibers, minerals, and unsaturated fatty acids. Nevertheless, these berries have short storage life which is the major constraint in their supply chains leading to higher postharvest losses. Inappropriate harvest handling, physical bruising, insect pests, and postharvest diseases lower the acceptability of fruit among consumers and other supply chain stakeholders. Additionally, the susceptibility to microbial decay, fruit softening, higher ethylene production, respiratory activity, and increased oxidation of anthocyanins, phenolics, and flavonoids considerably affects the marketability of Rubus …
