Study on preparation of apple and carrot paste for infants and the characteristic of its texture

Apples and carrots were used as raw materials,sucrose as a sweetener,citric acid as an acidifier,potato starch as a thickening agent to prepare apple and carrot paste for infants.Influence of content of ingredients in it on texture was studied through single factor experiments.The orthogonal experiments were used to determine the best formula by texture evaluation and experimental determination. The results indicated that ratio of apple and carrot,the amount of added sucrose,potato starch had an impact on the texture of the product,but the citric acid had no significant effect on it. The best formula was obtained through orthogonal experiments: apple ∶ carrot ratio of 5 ∶ 4,adding 4% of sucrose,0.2% of citric acid,0.5% of potato starch and 0.5% of water.
