Sensory evaluation of probiotic vegan Shrikhand
The sensory evaluation of probiotic vegan
shrikhand, was presented in (Table 2), provides valuable insights into the sensory attributes of control sample and different formulations of vegan probiotic shrikhand prepared from soya and coconut milk blending of fruit pulps (Mango and papaya). The sensory attributes, including color, texture, flavor, taste and overall acceptability, were evaluated for each shrikhand sample.
The control sample, prepared from buffalo milk, received moderate to high scores across all sensory attributes, with an overall acceptability score of 7.25. In comparison, the probiotic vegan shrikhand samples (T
1, T
2, T
3 and T
4) exhibited improvements in sensory attributes, particularly in color, texture, flavorand taste. These samples received higher scores, with T
3 scored the highest overall acceptability, indicating a preference for the probiotic vegan variations over the control sample. The observed improvements in sensory attributes of probiotic vegan shrikhand can be attributed to several factors. The use of soya and coconut milk as alternatives to buffalo milk may have contributed to the enhanced sensory characteristics, such as color, texture, flavorand taste. Additionally, the blending of fruit pulps (mango and papaya) could have imparted desirable sensory attributes, such as natural sweetness, aromaand fruit flavor, further enhancing the overall acceptability of the probiotic vegan shrikhand samples. A study by
Smith et al., (2020) investigated the sensory attributes of plant-based dairy alternatives, demonstrating similar improvements in color, texture, flavorand overall acceptability compared to traditional dairy products. Furthermore,
Patel and Gupta (2019) conducted a study on the sensory evaluation of fruit-infused dairy products, emphasizing the positive impact of fruit inclusion on sensory preferences.
The T
3 sample was prepared for (80% coconut milk + 20% soymilk) was selected as the optimized treatment based on its flavour and test. It achieved the highest sensory acceptability while maintaining desirable physicochemical properties, improved nutritional quality and satisfactory probiotic viability. Therefore, T
3 was considered the most suitable formulation for the preparation of probiotic vegan shrikhand.
Physicochemical characteristics of control sample and probiotic vegan Shrikhand
Physicochemical characteristics of probiotic Shrikhand analysed in the biochemical, nutritional value and sensory attributes of vegan Shrikhand. The probiotic vegan Shrikhand was analyzed for pH, TSS, acidity, moisture, carbohydrates, protein, fat, ash and crude fiber, with the findings shown in Table 3.
Shrikhand
Significant differences were been observed for in protein, crude fiber, fat, moisture, pH, TSS and acidity when comparing the selected sample (T3) with the control sample (T0). The pH of selected sample T3 (4.1) was notably lower compared to the control T0 (4.5). TSS reduced from 55.60°Brix in the control to 49.40°Brix in selected sample T3, primarily because of the substitution of sugar with jaggery powder. In the same way, acidity wlas notably reduced in selected sample T3 (0.96%) compared to the control sample (1.13%), which could be linked to the reduced acidity of coconut milk relative to dairy milk. The moisture level of selected sample T3 (55.96%) was notably greater than the control sample (50.41%), probably because of the addition of fruit pulp. The fat content increases to selected sample 17.69%, whereas the carbohydrate content decreases to 18.08% in the probiotic vegan shrikhand compared to the control sample. Similar effects of fruit incorporation on the physicochemical and sensory characteristics of shrikhand have been reported by
Suryawanshi et al. (2022), who observed significant changes in product quality following incorporation of papaya pulp and prebiotics.
Viscosity of probiotic vegan Shrikhand
The table presents the viscosity measurements of the control shrikhand (T
0) and the probiotic vegan shrikhand (T
3) was presented in Table 4. The viscosity of the probiotic vegan shrikhand is slightly higher than that of the control shrikhand, with values of 234±1.63 cP and 230±1.12 cP respectively.
The small increase in viscosity in the probiotic vegan shrikhand indicates a potential impact of the probiotic culture on the texture and consistency of the product. This change in viscosity could be attributed to the fermentation process initiated by the probiotic culture, leading to alterations in the structural components of the shrikhand. Increase in viscosity of control sample was been attribute to addition of fruit pulps, jaggery which ultimately raised the total solid content leading to increase in the viscosity of vegan shrikhand. The observed variation in viscosity was attributed to differences in total solids, protein-polysaccharide interactions and the development of the fermented product matrix, as changes in extract composition and soluble solids can modify gel strength and apparent viscosity. Similar formulation-dependent variation in viscosity was reported in fermented products, where interactions among extract solids, soluble fibres and the protein network influenced the final viscosity
(Isty et al., 2023).
Colour measurement of probiotic vegan Shrikhand
Color attributes of vegan shrikhand indirectly signifies the freshness, sensory appeal, shelf stability, asthetic appeal and marketability of finished product and therefore determination of color attributed particularly L, a, b, c and hue angle values are vital approach in determining the quality of prepared vegan shrikhand. Obtained results of color analysis are summarized in (Table 5).
L* value signify the degree of blackness to whiteness where o is for black and 100 is for complete white. L* value of selected sample was 46.79, however the control sample had high L* value of 83.27 which denotes the degree of whiteness was more in control samples compared to that of selected one. This decrease in L* value of selected sample was attributed due to the addition of fruit pulps, jaggery powder whereas control sample of shrikhand prepared with bovine milk. Positive values of a coordinate of color values signifies the degree of redness. a* value of control sample was 0.93, whereas selected sample had 12.08. b* value denotes the degree of blueness and yellowness. b* value of control sample was 12.90, whereas selected sample had 36.34 denoting the increased b* value of selected samples. This increased b* value of control sample was attributed to the added fruit pulps which had significant effects on b*value. C coordinate CIE system demonstrated the intensity or purity and known to be as chroma. Higher C value was observed for selected sample 33.08 compared to control sample 12.91. Marked increase in C value of prepared probiotic shrikhand was attributed to the added fruit pulps and jaggery powder. Hue angle was noted to inversely proportional to the chroma values as hue angle of selected sample 71.66 while control sample had 94.17.
Anarthe et al., (2026) studied the effect of pomegranate peel powder incorporation on the colour characteristics of shrikhand and reported changes in L*, a* and b* values with increasing levels of incorporation, which were attributed to the pigments and polyphenolic constituents contributed by the added pomegranate peel powder. Similar changes in colour parameters in the present study may be associated with the natural pigments and colour compounds contributed by the incorporated fruit and plant ingredients and their concentration in the product matrix.
Texture profile analysis of probiotic vegan shrikhand
Organoleptically most accepted vegan probiotic shrikhand and control sample were been assessed for various textural attributes and obtained results of analysis are tabulated in (Table 6).
Hardness of optimized product noted to be increased in vegan shrikhand by 65.92 N whereas that of control sample was 52.61 N. Rise in hardness of optimized product was attributed to the addition of fruit pulps and other constituents having a different biochemical composition affecting the hardness of product. Added fruit pulps has a pectin water binding capacity causing swelling and rise inconsistency of product
(Singh et al., 2022). Arun et al., (2018) found that TPA of low-calorie Shrikhand prepared by using stevia leaf powder showed hardness value decreases with decrease in amount of sugar.
Mehrotra et al. (2014) also reported higher hardness and consistency values of yogurt with increased fat content. Cohesiveness of prepared products was also reported to be increased compared to that of control sample. Springiness, which measures how quickly the shrikhand returns to its original shape after deformation, was slightly higher in the probiotic vegan shrikhand (T
3) which was (1.038) compared to the control having a (1.022). Gumminess, a combination of hardness, cohesivenessand springiness, was lower in the probiotic vegan shrikhand (T
3) compared to the control. These results suggest that the probiotic vegan shrikhand (T
3) has a firmer texture with slightly different cohesiveness, adhesiveness, springinessand gumminess compared to the control shrikhand (T
0). The variation in textural parameters were associated with differences in matrix composition and the extent of structural development during fermentation, as plant-derived solids and hydrocolloid-like components can influence the strength and cohesiveness of the product matrix. Similar formulation-dependent changes in textural characteristics have been reported in fermented yoghurt systems, demonstrating the influence of plant-based ingredient incorporation on hardness and related texture attributes (
Mariam and Kumari, 2024).
