Quality Attributes, Physiology, and Postharvest Technologies of Tomatoes (Lycopersicum Esulentum) – A Review

Quality Attributes, Physiology, and Postharvest Technologies of Tomatoes (Lycopersicum Esulentum) – A Review

2024 | Uchenna Emmanuel Umeohia, Abiodun Adekunle Olapade
This review paper discusses the quality attributes, physiology, and postharvest technologies of tomatoes (Lycopersicum esculentum). Tomatoes are a widely consumed horticultural crop rich in nutrients such as dietary fibers, phosphorus, iron, essential amino acids, minerals, vitamins, and sugars. From a consumer perspective, the desirable properties of fresh tomatoes are determined by visual appeal, firmness, taste, and dietary value. Postharvest losses are caused by a complex mix of physiological, pathological, microbiological, and mechanical processes. The rate of physiological processes such as respiration, transpiration, and ethylene production significantly affects the rate of senescence in fresh tomatoes. Postharvest handling systems are designed to reduce the consequences of these degradation activities on the quality of fresh tomatoes. Management procedures such as plucking, cleaning, sanitizing, initial cooling, sorting, and classifying, packing, storage, and shipping are crucial for preserving quality and extending storage life. Techniques for physical preservation include low temperature preservation, modified atmosphere packaging, 1-Methylcyclopropene, heating treatment, ultrasound treatment, UV-radiation, and edible coatings. Chemical methods include chlorinated water, oxonated water, and electrolysed oxidizing water. The review aims to examine the quality attributes of tomatoes affected by natural physiological processes and postharvest preservation technologies. Tomatoes are native to South America and are now cultivated worldwide. They are an essential horticultural crop with high nutritional value. Losses after harvest make production in developing countries unprofitable. The losses are due to improper harvesting, excessive field heat, poor sanitation, improper packaging materials, inadequate access roads, wrong transportation systems, and lack of processing and market facilities. The structure of tomatoes includes a fleshy pericarp with 2 to many carpels. The fruit composition includes 5-7.5% solids, mostly sugars and organic acids. The nutritional value of tomatoes includes vitamins, minerals, and fibers. The composition of dry matter in tomatoes changes as they develop from mature green to red ripe stages. Tomato cultivars vary in shape, size, and color. The choice of cultivar is based on factors such as ease of germination, cold resistance, uniformity, and disease resistance. The desirable qualities of tomato fruit include homogeneous size, shape, color, consistency, resistance to cracking, and good taste. There are around 7500 different tomato varieties globally. Heirloom tomatoes are becoming more popular due to their flavor and disease resistance. Tomato varieties are categorized into oblong and round types. The quality characteristics of fresh tomatoes include color, size and shape, texture, flavor, and nutritive value. Color is a vital quality parameter affecting appearance. The color of tomatoes varies from green at the unripe stage to deep red when fully mature. Lycopene and phytoene are the most abundant pigments in ripe tomatoes.
