Different decontamination processes

Non-thermal plasma is a new concept in food processing technology and reports available are scanty in India. To explore this novel physical decontamination technology to increase the shelf life of farm produce, a laboratory study has been carried out using cumin seed spiked with the different bacterial cultures.

Pulsed light is an emerging non thermal processing technology used for food decontamination. A laboratory scale pulsed light treatment chamber was designed and fabricated. In this study, tender coconut water was exposed to pulsed light to inactivate the E. coli using different process parameter such as juice layer depth (5, 10, 15 and 20mm), shelf height (5, 10 and 15cm) and number of pulses (60, 120, 180 and 240 flashes) corresponding to an fluency of 4.8, 9.6, 14.4 and 19.2J/cm2 .

Field and laboratory experiments were carried out to evaluate the effect of different decontamination processes on reduction of profenofos and chlorpyrifos residues in cauliflower curds like washing, cooking, washing plus cooking and dipping in chemical solutions after application of Profex 50EC (profenofos 50%) and Lethal 20EC (chlorpyrifos 20%) individually on the crop.

Experiments of field and laboratory were carried out to evaluate the effect of different decontamination processes on reduction of chlorpyrifos and cypermethrin residues in cauliflower curds like washing, cooking, washing plus cooking and dipping in chemical solutions after application of ready-mix formulation Cannon 55EC (chlorpyrifos 50% + cypermethrin 5%) on the crop. Ready-mix formulation Cannon 55EC was applied twice at the rate of 1ml/L at 15 days interval on cauliflower crop.

In order to increase agricultural production different type of pesticides viz., organochlorines, carbamates etc. are used on large scale to kill unwanted insects, pests, plants etc.; as mode of action of most of them is not specific, they often harm or kill organisms other than pests, including humans. Residues of most common pesticides could affect the ultimate consumers (animal and human) especially when pesticide treated fruit/vegetables are consumed raw. Proper processing technique in daily use of vegetables and fruits i.e. washing, peeling boiling, cooking, frying, sun drying etc.

Dissipation behaviour of novaluron 5.25% SC was investigated in tomato fruits sprayed at 43.31 (single dose) and 86.62 g a.i. ha-1 (double dose). Tomato fruits samples were collected periodically on 0 (1h after application), 1, 3, 5, 7, 10, and 15 days after application. Average recoveries of novaluron in tomato fruits fortified at 0.01 to 0.25 mg kg-1 levels ranged from 82.20 to 89.47 per cent. The initial deposits of novaluron were 0.30 and 0.56 mg kg-1 at single and double dose, respectively.
