Curious to understand the global phenomenon of cashew nuts? Excited to uncover the incredible health properties of these nuts? Then you’ve come to the perfect place! Let us be your guide as we delve into the “world of cashews” in full detail!
Journey back in time to discover the fascinating origins of the cashew tree ( Anacardium occidentale ), a botanical wonder that first emerged in the lush landscapes of Northeast Brazil. Initially thriving in the wild, gracing beaches and untamed lands, the cashew’s story took a dramatic turn in the 16th century. It was then that intrepid Portuguese explorers carried this remarkable tree across oceans, introducing it to India, Malaysia, and the shores of East Africa. Today, the cashew tree has flourished into a global crop, widely embraced in tropical havens across Asia.
In Vietnam, the Central Highlands and Southeast regions stand out as prime cashew cultivation zones. To help you, our farmers, select the best varieties for your land, we present the key morphological traits of the ideal cashew tree. These botanical indicators are crucial for identifying resilient varieties that promise high adaptability and consistently bountiful harvests throughout their remarkable lifespan. As a long-lived industrial crop, the cashew tree can flourish for 40-50 years, offering reliably high yields for a fruitful 10 to 20 years after planting.
Following the hard shell removal process, raw cashew nuts undergo testa (inner skin) removal to produce cashew kernels. To classify the finished cashew kernels, color quality serves as the primary criterion, dividing them into distinct groups.
Finished cashew kernels, after shelling, are then categorized into groups based on their color.
Ivory White (W) – The Premium Grade:
Representing the pinnacle of cashew quality and commercial appeal, Ivory White kernels boast a pristine bright white to elegant ivory hue. Prized for their near-perfection, these uniformly sized kernels are the preferred choice for upscale culinary creations and high-value export markets.
Pale Yellow (WW – Whole White) – High Quality, Slight Variations:
Pale Yellow kernels maintain high quality standards, yet may present minor imperfections like subtle scratches or slight color variations, permissible within quality tolerances. In larger volumes, the nuanced color difference compared to Ivory Whites becomes apparent. Still highly sought after, Pale Yellows are excellent for both export and domestic premium markets.
Black and Brown (BB – Black and Brown) – Economical & Industrial:
Distinctively darker in shade, Black and Brown kernels acquire their color from processing or inherent imperfections. Positioned at a more economical price point, these kernels serve smaller-scale food processing ventures, but primarily excel as the foundational ingredient for the cashew oil industry.
Split (SP – Split) – Versatile and Value-Driven:
Split kernels showcase a spectrum of colors – white, yellow, or brown – reflective of their origin and processing journey. Fragmented during shelling or heat treatment, these kernels may lack wholeness, but retain excellent quality. Their versatility shines in baking, food manufacturing, and the burgeoning plant-based milk sector.
Color, alongside form, stands as a critical determinant of cashew kernel quality, significantly impacting the pricing dynamics of raw cashew nuts.
