Apis mellifera L., a globally important pollinator, is crucial in the maintenance of its colonies due to a variety of stresses. Healthy nutrition is believed to help grow their population and relieve the stressors. We used our-prepared and commercial diets, and the nutrition contents were then analyzed for free sugar, organic acids, free amino acids, inorganic ions, total polyphenols, vitamin C, and the pH. The total free sugar, organic contents, free amino acids, inorganic ions, and total polyphenols were in the range of 228.59 to 661.00, 0.91 to 20.60, 6.52 to 24.36, 10.25 to 27.61, and 1.65 to 10.17 mg/g, respectively. The highest contents of free sugar, organic acids, free amino acids, inorganic ions, and total polyphenols were found in YBNH (661 mg/g), Megabee (20.60 mg/g), Beebread (24.36 mg/g), AIGT + Soytide (27.61 mg/g), and Beebread (10.17 mg/g), respectively. The pH values were maintained at 4.45 to 5.70 among all ten samples. Group I showed the same level of total free sugars (Group II and Group IV), organic acids (Group II), inorganic ions (Group II, Group III, and Group IV), polyphenols (Group II), and pH (Group IV). For the total free amino acids, Group I showed a significantly higher (P < 0.05) level than that of Group II and Group III. Group I had a comparable nutrition content to the commercial bee diet but had a higher total free amino acid content. High levels of inorganic ions, free amino acids, and organic acids were found in the AIGT + Soytide.
