Goji Berry and Wolfberry Concentrate Juice

With fresh wolfberry as the raw material, fresh wolfberry juice is manufactured through
pre-disinfections, enzyme treatment, juice extracting, color protection and
disinfections. The problems to keep wolfberry juice fresh at ambient temperature
have been solved, and the production of wolfberry juice has entered industrial
scale. The product is in form of orange-yellow juice. It is contained in aluminum-foil-plastic
bag (25kg/bag) in a carton box. The period of quality guarantee
is 12 months.
