Ingredient-specific reviewSpecifications vary according to fruit and ingredient format.
Fruit ingredients can differ substantially in natural solids, acidity, color, aroma and texture. Apple, pear and grape products may be evaluated differently from highly acidic citrus fruits, deeply colored berries or tropical fruits such as mango, pineapple and passion fruit. Crop origin, variety, maturity and processing method can also influence the final specification.
Juice concentrates and NFC juices are commonly reviewed for Brix, pH, titratable acidity, pulp or sediment and sensory characteristics. Purees may add viscosity, sieve size, seed or fiber content to the specification, while frozen fruits are typically defined by cut size, piece tolerance, color, defects and storage temperature. Powders may require moisture and mesh parameters, while fruit essences and citrus oils are more often evaluated around aroma profile, concentration, density, composition and storage conditions.
Requirements should also reflect the finished application. Beverage manufacturers may prioritize flavor, color, acidity and soluble solids, while dairy, bakery, confectionery and sauce producers may place additional emphasis on viscosity, particle size, processing stability or fruit preparation characteristics.
Common technical parameters
- Juices
