In our experiment, ferrous
benzoic xylenol orange (FBX) gel was prepared using gelatine (from bovine skin, Type B), ferrous ammonium sulfate (Aldrich ammonium iron (II) sulfate hexahydrate, 99% American Chemical Society (ACS) reagent), sulfuric acid (Sigma-Aldrich), xylenol orange tetrasodium salt (Sigma-Aldrich) and
benzoic acid (Sigma-Aldrich) formulated in 1998 by Kelly RG16 and others.13,14
analyzed benzoate in many kinds of dairy products and their report showed that
benzoic acid occurred naturally by microbial degradation or addition of an herbal essence which contains benzaldehyde [5].
Hydroxyl
benzoic esters are important kinds of preservatives, which are widely used in medicine, food, cosmetics, pesticides, and other fields [12].
Benzoic acid groups are attached to a solid support and reacted with amines.
Emerald Kalama Chemical, a business group of Emerald Performance Materials, announced that the company's board of directors has approved the plan to add a second

Animal food safety problems resulting from feeding antibiotics to animals, such as antibiotic residues and declining immunity, become increasingly severe (Aarnink and Verstegen, 2007), leading to the development of alternatives to antibiotics (including
benzoic acid and thymol) (Mroz, 2005; Janczyk et al., 2009).
Benzoic acid (BA) is one of the most important additives in the food industry.
