Received: [email protected]: DOI: October 03, 2019; November 04, 2019 10.31080/ASMI.2019.02.0422 Abstract - Tamarind pulp has potential value in nutrition and health and is useful in variety of ways in the preparations of both food, and medicines. There are several cultivars identified for industrial use, sweet and sour pulp types for table fruit purposes. Fruit is con sumed as fresh fruit snack, or its pulp made into puree or sauce to mix with rice and other cereals, vegetables, fruits, and to make candies, high energy bars, ready to use fresh fruit concentrates, sweet juice beverages or flavoring agent for locally consumed drinks, pickles, as a preservative to store several foods. The presence of antimicrobial properties and essential phytochemicals in tamarind pulp or pulp products made them safe for human and animal consumption and free of microbial load. There are reports on an insect - pest or larvae carried over from field to storage, enhanced losses of fruit quality and encouraging secondary pathogenic bacteria or fungal contamination. The climatic factors like temperature, relative humidity, ventilation, pH, amino acid to sugar ratio, and mois ture content of fruit or dried pulp blocks and their packing materials are some of the factors controlling the pulp quality. However, - care during selection of raw material, source location, processing methodology will eliminate cross contamination due to fungi or bacteria from food or food products prepared using tamarind pulp. The wild resources, 2000 genotypes and potential cultivars iden tified for pulp production would be an excellent source for seedless tamarind table fruit cultivar development. Postharvest studies on improved storage quality by using insect resistant cultivars and inclusion of ready to serve fresh foods with tamarind in United Keywords: States grocery stores would be beneficial.

Factors Influencing Postharvest Quality of Tamarind Fruit Pulp 11 Role of tamarind pulp in nutrition and health lowed by Thailand (140,000 tons) and 45% of tamarind trees are planted only for fruit pulp of food and medicinal value [3,4]. Various plant parts of tamarind including seed and leaves are - - highly nutritious, though fruit pulp is the prime part of this review. On an average 2000 genotypic collections were from all over - The biochemical components of medicinal value, and phytochemi the world and widely distributed in tropical and subtropical re cals of a preservative role were controlling various human or ani gions including Europe and Americas. Among these the sweetest - mal infections or diseases are summarized below [6]. and most cultivated tamarind cultivars with high pulp content are Makham Waa, Manila sweet, Urigam, PKM 1 (Peryakulam 1), Tum Fruit pulp used as snack, preservative, and to prepare several kur, Yogeswari, No: 86-13-008, No: 87-2-01-035, Prathisthan, T3, - culinary dishes, chutney, tamarind juice concentrate, pulp powder, T1B, red and brown pulp type, sweet and sour type fruit cultivars - pectin, jams, syrups, candy, and for making souring porridge, tar for their industrial use traits. Tamarind tree can be cultivated as taric acid, alcohol, summer refreshing drink, seasoning, and flavor a main orchard or as an intercrop in vegetable crops like cassava, ing [4]. The fresh raw fruit of 100g weight provides 239 kcal energy. potato and other annuals or cereals like wheat [4-7]. The proximate composition of fruit pulp (Table 1) though varies with sample to sample, revealed that the ripe fruit pulp provides Evaluation of Tamarind varieties were conducted from various 30-40% invert sugars containing 70 per cent glucose and 30 per locations of south India (Tamil Nadu - 14 genotypes, Karnataka - - cent fructose, more folates (59.35μg), tartaric acid (18.52g/100 11 genotypes, Andhra Pradesh - 10 genotypes) including famous - g), soluble solids (44oBrix) and vitamin E (108.78μg/g), but less varieties like Urigum, PKM-1 (Tamil Nadu) and NT1-19 (Karna - dietary fiber (4.13g/100 g), vitamin C (4.79mg/100g) and carbo taka) and selections. Correlation coefficient studies indicated that hydrates (50.07g/100g) compared to raw fruit [4,6, https://fdc.nal. pulp weight per pod expressed highest positive genotypic and phe usda.gov/]. notypic association with pod weight, vein weight, shell weight, pod width and pod length.
