Moisture content, ash content, acidity of both the yogurt samples (C and D) was determined by AOAC (1999) 21 official methods. log p log q 3 0 1 B2 3 p p log 0 or log 0 q 3 q pq 3 1 log p log q or log p log q 3 3 N Paper 1, Question 9 Given the geometric progression 10 20 5,,. Diffusion of tannin from the pulp to mucilage with delay in postharvest processing may be responsible for increased apparent viscosity with increased PHT. Rheocalc V3.2 Build 47-1 where, Herschel-Bulkley math models provide a numerically and graphically analyze for the behavior of data sets. Microstructural examination of the mucilage revealed that certain weak structures as phloem vessels found in the mucilage may be destroyed upon application of shear stress and may contribute to the pseudoplastic nature of the mucilage. the mucilage of the Caturra variety was more viscous and shear thinning than that of the Colombia variety. The measurements revealed viscosities of 23.0 cps at 50° C.

During FFT deposition, development of yield stress and dissipation of shear will in due course arrest FFT flow (Tilton 2013). Viscosity measurements were taken for the second example using a Brookfield DV3 rheometer with Rheocalc software (18 spindle, 60 RPM). with 5000 cP viscosity standard (RRM5907, batch 110514, Brookfield, expiry ). the K increased and n decreased as the RCC and PHT increased. 3.3 Discharge flow properties As discussed in Sections 3.1 and 3.2, silica treatment immediately modifies FFT viscosity and ultimately creates a silica network within the water phase of the FFT increasing its yield stress. Viscosity assessments were carried out on a Brookfield DV-III Ultra Programmable Rheometer operating with Rheocalc v3.3 Build 49.0 (Brookfield Labs, 1999) and spindle CP-52. the mucilage is a highly viscous and pseudoplastic (n < 0.3) fluid. the power‐law model was used to describe the shear stress versus shear rate data, and the consistency index (K) and flow behavior index (n) were determined. A Brookfleld HB DV‐III viscometer was used in concentric cylinder geometry over a shear rate range of 4.8 to 120 s−1.

Rheological behavior of mucilage obtained from two varieties of coffee grown in Colombia (Caturra and Colombia) was studied as a function of ripe cherry content (RCC) and postharvest time (PHT). HPAM synthesis : Figure 4a shows that the viscosity of polymer dropped from temperature 30 : o: C to 60 C in the concentration HPAM free salinity.
