Juice and Pulp Testing Services by YMC

Juices and pulps, derived from a variety of fruits and vegetables, are widely appreciated for their nutritional benefits and refreshing flavors. However, their quality, safety, and authenticity must be ensured through rigorous testing. The presence of contaminants, adulterants, or poor processing can diminish both the health benefits and shelf life of these products. Testing verifies the nutritional composition, purity, and regulatory compliance of juices and pulps, helping maintain consumer trust and product integrity.

YMC provides comprehensive testing solutions for juice and pulp manufacturers, helping them uphold the highest safety standards and meet regulatory requirements. With state-of-the-art laboratories and advanced analytical methodologies, YMC ensures accurate, timely, and reliable analysis tailored to industry needs.

 

Nutritional and Composition Testing

Juices and pulps are valued for being nutrient-rich. YMC performs in-depth testing to evaluate the nutritional profile of these products.

Key Parameters Include:

• Vitamin Levels: Determination of essential nutrients such as Vitamin C, Vitamin A, and B-complex vitamins.

• Mineral Content: Measures calcium, potassium, magnesium, and iron content.

• Total Solids: Indicates the concentration of sugars, fiber, and other non-aqueous components.

• Sugar Profile: Assesses glucose, fructose, sucrose, and total sugar content.

• Acidity Testing: Includes pH and titratable acidity to assess preservation quality and flavor balance.

 

Microbiological Safety Assessment

Microbial contamination in juices and pulps poses serious risks to consumer health. YMC conducts thorough microbiological analyses to ensure product safety.

Core Tests Include:

• Total Plate Count (TPC): Evaluates the overall bacterial load.

• Pathogen Detection: Includes Salmonella, Listeria, and E. coli screening.

• Yeasts and Molds: Detects spoilage-causing fungi.

• Coliforms and Faecal Contaminants: Identifies potential hygiene-related issues.

 

Contaminant and Adulterant Analysis

Adulteration and chemical contamination can severely compromise the safety of juices and pulps. YMC provides specialized testing for:

• Pesticide Residues: Detection through GC-MS to ensure adherence to national and international limits.

• Heavy Metal Content: Testing for mercury, lead, cadmium, and arsenic using ICP-MS.

• Additives and Preservatives: Identification of sulphur dioxide, synthetic dyes, and artificial sweeteners.

• Non-food Adulterants: Detection of harmful substances like melamine.

 

Sensory and Quality Evaluation

Sensory characteristics directly impact product appeal. YMC conducts scientific and sensory evaluations to maintain quality and consistency.

Analytical Aspects Include:

• Visual Attributes: Clarity, color consistency, and sediment presence.

• Flavor and Aroma Testing: Ensures products meet organoleptic expectations.

• Texture and Mouthfeel: Especially relevant for pulps—assesses viscosity and pulpiness.

• Cloudiness: Monitors potential microbial growth or filtration issues.

 

Shelf-Life and Stability Testing

Understanding how juices and pulps behave over time is crucial for determining best-before dates and storage guidelines. YMC offers real-time and accelerated shelf-life studies.

Parameters Evaluated:

• Temperature Impact: Assesses product changes under various storage conditions.

• Microbial Growth Over Time: Tracks spoilage and contamination risks.

• Nutritional Degradation: Measures vitamin and mineral stability during shelf life.

• Packaging Interaction: Ensures containers do not compromise product safety or flavor.

 

Regulatory Compliance & Labelling Standards

 

FSSAI Guidelines (India)

• “100% juice” claims prohibited for reconstituted products starting Sept 1, 2024.

• Reconstituted juices must be clearly labelled.

• Sugar above 15 g/kg requires “sweetened juice” label.

• Preserves minimum fruit content and restricts sugar usage in canned fruits.

 

EU Directive 2001/112/EC

• Defines legal standards for juice composition and quality.

• Requires accurate ingredient disclosure and concentration labelling.

• Regulates naming to avoid misleading claims.

• Sets clear guidelines for “from concentrate” declarations.

 

Advanced Analytical Technologies Used by YMC

• HPLC & GC (Chromatography): For quantifying sugars, acids, and chemical residues.

• UV-Vis & FTIR (Spectroscopy): For analyzing color, content, and quality.

• Mass Spectrometry (MS): Identifies trace contaminants, including pesticides and adulterants.
