<p>Methods are provided for thermally processing a plastic container having foodstuff therein to reduce softening and distortion of the plastic during thermal processing, wherein by combining the foodstuff with an acidulant and thereby reducing the pH of the foodstuff to 4.6 or below, the thermal processing time/temperature parameter is reduced below what it would have been without the acidulant. Thanks to the reduced severity of processing, softening and distortion of the plastic is significantly reduced. Preferred acidulants are mixtures of lactone-forming acids and their lactones, for example glucono-delta lactone.</p> |
