Review on Establishment of a Production and Export Unit for Cashew Based Nutraceutical Soft Gelatin Capsule

Nutraceuticals may be defined as ‘any substance that may belong to a plant, food or an essential component of food providing definitive medicinal usefulness and health promotion as well as physiological benefits and ultimately minimize the possible risk of the prevailing chronic disease significantly. Nutraceuticals is a term derived from “nutrition” and “pharmaceutics.” The term is applied to Products that are isolated from herbal products, dietary supplements (nutrients), specific diets, and processed foods such as cereals, soups, and beverages that other than nutrition are also used as medicine. Common examples are cashew nut, almonds, walnuts, pistachios, flaxseeds, chia seeds, sunflower seeds, oats, barley, quinoa, amla, salmon, sardines, olive oil, yogurt, honey, dark chocolate, spirulina etc. and their chemical constituent’s relation to biological values has virtually succeeded in combating the human ailments and sufferings to an appreciable extent across the globe. There may be used to improve health, delay the aging process etc ^[1] Nutraceuticals have been used not only for nutrition but also as a support therapy for the prevention and treatment of various diseases, such as to reduce side effects of cancer chemotherapy and radiotherapy. Diverse novel ‘nano’ formulation approaches tend to overcome challenges involved in formulation development of nutraceuticals. Prior information on various interactions with drugs may help in preventing any deleterious effects of nutraceuticals products. Nanotechnology also leads to the generation of micronized dietary products and other nutraceutical supplements with improved health benefits. The latest key findings (clinical studies) on nutraceuticals that show the therapeutic action of nutraceutical’s bioactive molecules on various diseases have also been discussed. ^[2]

Market Interest of Nutraceuticals

The nutraceutical market is becoming more competitive with the entry of pharmaceutical and major food companies into the nutraceutical arena. Also, many food companies have established their nutraceutical divisions with a view toward a diversified product line. Recent years have marked the entry of major food and pharmaceutical companies into the nutraceutical marketplace, including Kellogg, Heinz, M&M, Quaker Oats, Unilever, Cargill, Hormel etc. The global nutraceutical retail market was estimated at approximately $106 billion in 2004.

Relevance of Converting Cashew Kernel into Capsule Form

1. Dose Standardization

Converting cashew kernel (Anacardium occidentale L.) into capsule form ensures a precise and uniform dose of bioactive constituents such as monounsaturated fatty acids (oleic acid), phytosterols (β-sitosterol), flavonoids, phenolic compounds, tocopherols, magnesium, and zinc. This guarantees reproducible therapeutic benefits, especially for cardiovascular and metabolic support.

2. Controlled Therapeutic Intake

When consumed as whole nuts, the quantity of beneficial components varies depending on portion size and preparation. Capsule formulation provides a fixed daily dose, making it suitable for therapeutic use in conditions like hyperlipidemia, hypertension, and metabolic syndrome.

3. Improved Stability of Bioactive Compounds

Cashew kernels contain unsaturated fatty acids that are prone to oxidation and rancidity. Encapsulation protects these sensitive constituents from environmental factors such as air, light, and moisture, thereby enhancing shelf life and maintaining antioxidant potency. ^[3]

4. Enhanced Patient Compliance

Capsules are convenient, portable, and easy to consume. They eliminate the need for measuring or consuming calorie-dense nuts daily. This improves adherence, particularly among elderly individuals and patients requiring long-term supplementation.

5. Calorie Control and Fat Regulation

Whole cashew nuts are energy-dense Capsule form allows administration of beneficial lipid fractions and micronutrients without excessive caloric intake, making it appropriate for individuals managing weight or metabolic disorders.

6 Targeted Nutritional Therapy

Cashew kernel capsules can be positioned specifically for cardiovascular health (cholesterol regulation, endothelial protection), antioxidant support (free radical scavenging), bone health (magnesium and phosphorus supply), and immune enhancement (zinc and selenium support).

7 Scientific Validation and Market Positioning

Capsule formulation enables standardization, quality control, and clinical evaluation. This strengthens its credibility as a plant-based nutraceutical rather than merely a functional food.

8. Preventive Healthcare Application

With the growing focus on preventive medicine, cashew-based nutraceutical capsules provide a natural strategy to reduce cardiovascular risk, oxidative stress, and micronutrient deficiencies.

Regulations of nutraceuticals

The term “foods for particular dietary needs” refers to nutraceuticals throughout India. “Foods for specialized dietary applications or functional food ingredients or nutraceuticals or health products,” according to the Food Safety and Standards Authority (FSSAI), are defined. The Food Safety and Standards Act of 2006 in India created the Food Safety and Standards Authority of India (FSSAI), that combines several statutes and rules and were in place to address food-related problems in several Ministries/Departments. In place to ensure that there is a supply of healthy” safe food for humans, the FSSAI was established to establish scientific food standards commodities and to control their production, preservation, delivery, sales, and purchase.

India: FSSAI’s comprehensive 2022 regulations

India has established a detailed regulatory framework through the Food Safety and Standards Authority of India’s 2022 regulations. These regulations, re-operationalized in October 2022, outline requirements for health supplements, nutraceuticals, foods for special dietary use, and related products.

FSSAI’s key requirements

 The regulations provide clear product categorization, and permit ingredient lists with specific usage ranges. Manufacturers must follow detailed labelling requirements, including mandatory warnings and recommended usage information. Products cannot make disease treatment claims and must clearly state they are not substitutes for a varied diet

Essential testing requirements for compliance Regardless of the regulatory framework, nutraceuticals must undergo rigorous testing to ensure consumer safety and regulatory compliance. These tests verify product quality and substantiate health benefit claims^{. [6]}

Indian regulatory requirements

1. Product assessment: evaluation of every compound and active component. There are several steps in the product evaluation.

2. Licenses: About 4–5 licences necessary to register a product.

3. Health claims on food labels: A “health claim” is any statement, suggestion, or implication that there is a connection in between food or one of its ingredients and health.

GMP GUIDELINES

Good Manufacturing Practices, or GMP, are a set of regulations designed to ensure that products are consistently produced and controlled according to quality standards. In the context of pharmaceuticals and nutraceuticals, GMP guidelines are critical for safeguarding public health, ensuring the safety, quality, and efficacy of products intended for human consumption. For nutraceuticals, GMP compliance is governed by the U.S. Food and Drug Administration (FDA) under 21 CFR Part 111, also known as the Dietary Supplement Current Good Manufacturing Practices (CGMPs). The FDA’s CGMP requirements specifically address the manufacturing, packaging, labelling, and storage of dietary supplements to prevent adulteration, contamination, and mislabelling.

• Quality Management Systems (QMS)

• Personnel & Training

• Facilities & Equipment

• Raw Material Control

• Production Controls

• Packaging & Labelling

• Documentation & Traceability

HACCP

HACCP (Hazard Analysis and Critical Control Points) for nutraceuticals is a systematic, preventive management system used to minimize biological, chemical and physical hazards. It ensures dietary supplements and health foods are safe for consumption, rigorously tracing and controlling risks from raw ingredients to final packaging^{. [7]}

Three Major Types of FSSAI License in India

There are three types of FSSAI/Food Licenses in India: Basic, State, and Central licenses. These are classified in the basis of turnover and described below:

• FSSAI Basic License/Registration: For businesses with an annual turnover under 12 lakhs, they must register with FSSAI through FSSAI Basic License.

• FSSAI State License: Businesses with an annual turnover between 12 to 20 crores should apply for the FSSAI State license using Form B.

• FSSAI Central License: If the annual turnover exceeds 20 crores, businesses should opt for the Central License using Form B.

Environmental Control & Room Specifications for Cashew Based Nutraceutical Capsule Manufacturing:

1. Regulatory & Structural Foundation

The facility must adhere to a combination of Schedule M (India GMP), WHO GMP, and FSSAI Nutraceutical Guidelines (2018) to prevent contamination and ensure consistent quality.
