Walnut is a very useful product, therefore its consumption in the world is growing every year. Fresh light walnut is most valued, since it has a more attractive appearance, is associated with quality and, most importantly, contains the maximum amount of useful microelements.
It turns out that the first thing you need to pay attention to is the appearance.
The nut shell should be light, free from damage and stains. The reasons for dark, dirty or stained shells can be untimely collection, a long stay of the nut in the green pericarp, storage of the nut in dampness. All this can lead to the fact that the kernel of the nut darkens or becomes moldy.
Nut weight. Freshly harvested walnuts have high moisture content and are heavy. It must be dried before or after processing to preserve its quality.
Large weight and high humidity outside the harvesting season should be alarming – the nut could be stored in dampness, which threatens mold, or it was specially wetted to increase weight.
A nut with a thick shell (“greedy nut”) can also be weighty. Due to its structure, it requires a lot of effort to clean up and does not give a whole kernel.
An overdried nut has too little weight, it is very fragile and easily crumbles when splitting, or a nut whose kernel has completely dried out.
You should choose a moderately dry nut, it has an optimal weight and does not crumble when split. You can also buy a heavy wet nut during the picking season, but you need to understand that it requires drying.
Every batch, and ideally every bag, should be tested. For this, nuts are selected from different parts of the bag. The shell of a high-quality nut is thin, the nut breaks easily and at the same time the kernel does not crumble, it is light, without traces of spoilage and the smell of dampness. The processing of such a nut will be the most simple and profitable.
By processing quality nuts, you can get the maximum yield of light whole kernels. It is they who have the greatest demand and the highest cost. That is, by purchasing a high-quality nut, you can earn more and not spend a lot of time looking for a buyer.
