The main reason: Nongfu Spring Orange 17.5° is the navel orange variety Newhall navel orange.

It is named 17.5° because the USDA defines the sugar-to-acid ratio of Type A orange juice as 12.5-20.5, a range that takes into account the importance of acidity in oranges.

The skin is thin, the meat is large, the meat is full, the water is sufficient, the pomace is less, and it is rich in fruit acids such as citric acid, malic acid, and succinic acid, which are beneficial to human health.

Notes:

Nongfu Spring has developed 4 standard systems, 34 operating procedures, 79 control contents, and 148 monitoring items for fresh fruits, and has established an intelligent screening of navel oranges. system.

Before picking, Nongfu Spring will randomly select samples from each orchard. Two samples will be taken from each tree, including outer and inner fruits, and more than 20 samples will be taken from each orchard. Only after the sugar-acid ratio is tested to meet the requirements can the fruit be picked.

Navel oranges are transported to Xinfeng factory for sorting within 24 hours after being picked. On the automatic production line, 40 photos are taken of each orange and the area of ??each scar point is accurately measured. Intelligent sorting via an automatic weighing induction system, where each orange is measured and re-sorted. Each orange is then subjected to a non-destructive infrared scan to determine the sugar-acid ratio.

After a standardized sorting process, the skin and head of each orange should be uniform.
