 หัวเรื่อง:ไม่มีชื่อไทย (ชื่ออังกฤษ : Qualities of Tofu Powder as Affected by Soybean Variety, Coagulant and Drying Method) ผู้เขียน: Woralak Panyathitipong, Yuporn Puechkamut สื่อสิ่งพิมพ์:pdf AbstractEffects of soybean varieties and tofu powder processing on the qualities of the tofu powder was studied. Soybean varieties (CM 60, SJ 5 and ST 2), commercial coagulants (2.2% CaSO4, 3.0% CaCl2, 2.2% MgSO4 and 3.0% MgCl2) and drying methods (tray dryer, drum dryer and freeze dryer) were studied with respect to their effects on the qualities of tofu powder produced. Soybean varieties influenced the qualities of soybean and soymilk and also affected the functional properties of tofu powder. Tofu powder obtained from CM 60 gave a high yield and good functional properties. Calcium ion coagulant induced tofu powder gave a high solubility and magnesium ion induced tofu powder gave a high emulsion activity. The tofu powder which was freeze dried had a high solubility and high emulsion activity but low emulsion stability. |

หัวเรื่อง:ไม่มีชื่อไทย (ชื่ออังกฤษ : Effect of Tofu Powder and Carrageenan on Functionality and Physical Characteristics of Surimi Emulsion Gel) ผู้เขียน:Woralak Panyathitipong, Yuporn Puechkamut สื่อสิ่งพิมพ์:pdf AbstractThe effect of tofu powder and carrageenan on the functionality, textural parameters and microstructure of surimi emulsion gel were studied. Tofu powder (20, 40, 60 and 80%) was used as a replacement for surimi as a pre-emulsion in the formulation of the emulsion gel. The tofu powder increased the emulsion stability, water holding capacity (WHC) and hardness of the gels. Microstructural observation supported the texture profile analysis (TPA) and functionality results. Evaluation was carried out on the addition of carrageenan at various concentrations (0.25, 0.5 and 0.75%) to the gel that replaced 80% of the surimi with tofu powder. Increasing carrageenan also improved the stability of the emulsion, WHC and hardness of the gels. Microstructural observation showed that the addition of carrageenan resulted in a smoother and more compact gel network. |
