Brom cresol green

All ingredients used for pudding preparation were commercial products procured from a local supermarket in Istanbul, Türkiye. Eight different types of commercially available UHT plant‐based milks (low‐fat (1.5%) and whole‐fat (3%) cow's milk, almond, oat, Antep pistachio, coconut, soya, and hazelnut plant‐based milks) were used, and all puddings contained rice flour and sugar. The chemicals used in this study, including sodium hydroxide (NaOH), boric acid (H₃BO₃), sulfuric acid (H₂SO₄), copper (II) sulfate (CuSO₄.5H₂O), potassium sulfate (K₂SO₄), methyl red, brom cresol green, ethyl alcohol, and petroleum ether, were of analytical grade and were obtained from Merck Chemicals (Darmstadt, Germany).

Ingredients used in this research included an antagonistic test on enteric pathogen microbe used in MRSB/de MRS Broth (Oxoid) media, nutrient agar media (NA and Oxoid), and nutrient broth (NB and Oxoid). Media used in the survival test on acidity were MRSB (Oxoid), MRSA (Oxoid), 0.85% of sterile NaCl, as well as HCl. Media used in the bile salts test were MRSB (Oxoid), MRSA (Oxoid), 0.85% of sterile NaCl, as well as ox gall 0.3% (Oxoid). Media used to test crude protein proximate analysis were Tablet Kjeldhal (Merck), H₂SO₄ (Merck), NaOH 40% (Merck), boric acid (Merck), methyl red (Merck) indicator, Brom cresol green (Merck), H₂SO₄ 0.01 N (Merck), and Aquadest.
