Abstract:
Background: One of the significant problems with peanut butter is oil separation
when the product is opened after some time. The selection of vegetable oil, which acts as a stabiliser,
plays a significant role in nut butter's textural and sensory quality.
Objective: This study aimed to optimise the formulation of cashew nut butter using response surface
methodology (RSM). Four different vegetable oils, namely olive oil, virgin coconut oil,
soybean oil and palm oil, were used to select efficient vegetable oil based on its effect on the
physicochemical characteristics and sensory evaluation of cashew nut butter.
Methods: Thirteen formulations of cashew nut butter from RSM were produced to determine the
optimum amount of selected oil (olive oil) and honey.
Results: Cashew nut butter stabilised with olive oil showed the best and similar values to commercial
peanut butter with the lowest oil separation 3.91% and lower values of texture data of
firmness (85.8 g), shear work (87.8 g.sec), stickiness (-27.44 g) and work of adhesion (-36.07
g.sec). The recommended volumes of olive oil and honey for cashew nut butter production were
1.29% and 6.16%, respectively. Consumers favor cashew nut butter, according to sensory analysis'
overall acceptance. In terms of nutritional quality, cashew nut butter contains a high amount
of fat (47.25%), followed by carbohydrates (24.51%) and protein (16.4%).
Conclusion: The type of oil showed significant effects on the stability and spreadability of the
produced cashew nut butter.
