Scientific Reports’ta yay\u0131nlanan makalenin yazarlar\u0131ndan Adam van Casteren, “Mikro dokular \u00fczerinde yapt\u0131\u011f\u0131m\u0131z \u00e7al\u0131\u015fmada f\u0131nd\u0131k ve tohum kabu\u011fu gibi sert bitki dokular\u0131n\u0131n etkilerini g\u00f6zlemledik” a\u00e7\u0131klamalar\u0131nda bulundu. Bu konudaki yerle\u015fik d\u00fc\u015f\u00fcnce sert yiyeceklerin di\u015fler \u00fczerinde mikroskobik etkiler b\u0131rakaca\u011f\u0131 y\u00f6n\u00fcndedir. Van Casteren, “Ancak di\u015flerin mikroskobik d\u00fczeyde izler ta\u015f\u0131mamas\u0131 durumunda sert yap\u0131l\u0131 g\u0131dalar\u0131n t\u00fcketilmedi\u011fi d\u00fc\u015f\u00fcn\u00fclmemelidir” dedi.<\/p>\n

Bununla birlikte sert yap\u0131l\u0131 maddelerde di\u015f minesine s\u00fcrt\u00fcnmekten kaynaklanan bozulmalar g\u00f6zlendi.
