a Fluorescent images showing the ALP coating before and after cleaning with Congo red staining. b Water contact angle measurements on ALP-coated cherry tomatoes and bananas before and after cleaning. c Pathological examination results of heart, liver, spleen, lung, kidney, and intestine tissues. The control group was fed bare rat food, while the coated group was fed ALP-coated rat food. Results of (d) blood routine (white blood cell (WBC), neutrophil (Neu), lymphocyte (Lym), (e) liver function (alanine aminotransferase (ALT), aspartate transaminase (AST)), and (f) kidney function tests in both control and coated groups are presented (creatinine (CREA), blood urea nitrogen (BUN)). n = 6 animals per group. Data are presented as a box and whisker plot (median, box:first and third quartiles, and whisker: minimum and maximum). All data in Fig. 6d–f are mean ± S.D. Statistical significance was determined by a two-tailed Student’s t test. The experiments in (a, c) were repeated independently at least three times with similar results. Source data are provided as a Source Data file.
