    Development of processing technology for instant mango shake powder
    (CCSHAU, 2018) Priyanka; Rekha
    The present investigation ―Development of processing technology for instant mango shake powder‖ was conducted with the objectives to optimize processing technology for development of instant mango shake (IMS). Fresh and six months stored frozen pulp mango pulp had total soluble solids (19.56 and 16.39 %), acidity (0.41 and 0.43 %), ascorbic acid (6.96 and 5.73 mg/100 g), reducing sugars (5.79 and 5.93%), total sugars (13.24 and 13.79%), pectin (0.51 and 0.54%), total carotenoids (1.24 and 1.15 mg/100 g) and total phenols (42.33 and 39.67 mg/100 g) Mango pulp was blanched in microwave (2.00 min. /100 g at 900W). After blanching, the product was either freez dried, tray dried or microwave assisted tray dried. After drying, dried mango pulp was ground to powder, mixed with skim milk powder (SMP) and sugar in 32:26:42 ratio, packed in aluminum laminated and polypropylene pouches and stored for three months at room temperature. IMS1 (prepared from mango pulp, mixed with skim milk powder and freeze dried) and IMS2 (prepared from microwave assisted tray dried mango pulp) had moisture content (4.60 and 4.15%), crude protein (0.82 and 0.77%), crude fat (0.42 and 0.46%), crude fibre (0.93 and 0.89%), ash (1.47 and 1.45%), carbohydrates (96.27 and 96.42%), energy (393.93 and 393.93 Kcal), calcium (262.67 and 252.33 mg/100 g), ascorbic acid (5.75 and 5.01 mg/100 g), carotenoids (1.14 and 1.09 mg/100 g), total phenols (39.19 and 34.17 mg/100 g), bulk density (0.94 and 0.89 g/cm3)and dispersibility (86.87 and 82.93%) The most acceptable instant mango shake powder i.e., mango pulp mixed with skim milk powder and freeze dried had moisture (4.60%), protein (0.82%), fat (0.42%), crude fibre (0.93%), ash (1.47%), carbohydrates (96.27%), energy 392.90 Kcal and calcium (262.67 mg/100 g), ascorbic acid (5.75 mg/100 g), total Carotenoids (1.14 mg/100 g) and total phenols (39.19 mg/100 g) Moisture content, water activity, acidity, non enzymatic browning, total soluble solids, solubility index and microbial load increased while, pH and ascorbic acid of the all three instant mango shake powder variants decreased significantly during three month of storage. Cost of IMS powder ranged from `247.54 to 46.72/100 g. All the instant mango shake powder variants were found acceptable even after three months storage.
