The invention provides strong loquat syrup and a preparation method thereof, and the strong loquat syrup comprises the following components in parts by
mass: 69g-80g of loquat leaves; 50 g to 62 g of pericarpium papaveris; 15 g to 25 g of radix stemonae; 9 to 20 g of
cynanchum glaucescens; 6-18 g of cortex mori radicis; 6 g to 15 g of platycodon grandiflorum;
menthol, 0.15 g to 0.98 g of
menthol; an auxiliary material: 45 g to 55 g; 2.5 g to 3.3 g of
sodium benzoate; 0.08 g to 0.17 g of
citric acid; and 800 to 1500 g of water. According to the strong loquat syrup disclosed by the invention, when the
sugar content in the strong loquat syrup is reduced, the pH value of the strong loquat syrup can be kept at 4.4-5.0 through
citric acid, the stability of the strong loquat syrup can be ensured, the taste of the strong loquat syrup is more comfortable, the
relative density of the strong loquat syrup is kept, and in addition, the strong loquat syrup has the advantages that the
sweet taste of the strong loquat syrup is improved; according to the present invention, the
sucrose content is reduced while the
sodium benzoate is added, such that the strong loquat syrup is stable, the safety of the strong loquat syrup is ensured while the
sodium benzoate is added, and the pH value of the strong loquat syrup is 4.4-5.0 so as to improve the
antibacterial effect of the strong loquat syrup.
