INTRODUCTION
Background of the Study
The production of crackers, popular snack foods characterized by their crisp texture, appealing appearance, and
versatile flavoring, is constantly evolving. The food industry is increasingly focused on enhancing both the
nutritional content and sustainability of its products (Singh & Sharma, 2020). This trend includes the exploration
of locally sourced and sustainable ingredients to improve the nutritional value of snack foods while minimizing
environmental impact. Shellfish by-products, rich in minerals like calcium, are gaining attention as a potential
source for fortifying food products, offering a sustainable alternative to traditional methods (Chen & Li, 2021).
Green mussel shells (Perna viridis), in particular, offer a valuable resource due to their high calcium carbonate
content and potential for improving bone health. The incorporation of shell waste into cracker production not
only boosts nutrition but also promotes environmentally responsible food processing (Yamamoto et al., 2022).
Research on the impact of shell-based ingredients on cracker properties and sensory acceptability is ongoing.
Studies prior to 2022 have shown the effects of shell flour on texture and color, highlighting the need for
optimization of formulation and processing methods. The use of cockleshell waste as a humidity adsorbent in
keropok (fish crackers) has shown promise in extending shelf life by effectively reducing water activity and
maintaining desirable sensory qualities (Hidayati & Fitria, 2016; Tabo et al., 2018). These findings suggested
the potential for enhancing cracker quality and stability using sustainable and readily available resources.
Traditional cracker production methods, such as those employed in the Indonesian susuh scallop cracker industry
(Junianto et al., 2023), often rely on manual processes that may limit consistency and scalability. Modern food
science can provide valuable tools for optimizing traditional methods and unlocking the full potential of both
established and novel approaches to cracker production.
This study focuses on the acceptability of Banisil crackers, a traditional Filipino snack, potentially fortified with
green mussel shell flour, and further examines the role of cockleshell waste in controlling moisture content. The
research aimed to advance sustainable food development practices, enhancing the nutritional and sensory profiles
of a traditional product. By combining traditional food production techniques with modern food science
principles, this research can contribute to innovations in the food industry while supporting local resources and
environmentally sustainable practices. The results will inform product optimization, marketing strategies, and
future research in this area.
THEORETICAL FRAMEWORK
The acceptability of Banisil crackers with Malunggay can be understood through several key theories that
highlight the importance of sensory attributes in food products, specifically focusing on texture, appearance,
taste, and aroma. Sensory evaluation theory posits that these sensory characteristics significantly influence
consumer enjoyment and preference (Stone & Sidel, 2004). For Banisil crackers, achieving the right balance of
crispiness and crunchiness is essential for a satisfying eating experience, as noted by Meilgaard, Civille, and
Carr (2007), whom emphasized the importance of texture in food products.
Consumer preference theory further explains that individual experiences, cultural backgrounds, and marketing
influences shape consumer choices (Schiffman & Kanuk, 2007). As a traditional Filipino snack, Banisil crackers

benefit from cultural familiarity, enhancing their acceptability. Incorporating local spices and flavors allows
manufacturers to align the product with consumer tastes, making it more appealing.
Aroma and flavor perception also play a crucial role in the overall enjoyment of food. Research by Auvray and
Spence (2008) indicated that aroma significantly impacts flavor perception, and the scent of Banisil crackers can
evoke positive memories, enhancing the eating experience. Innovations that focus on enhancing the natural
fragrances of the ingredients can further improve consumer acceptability.
Additionally, visual appeal and packaging are vital in attracting consumers. Underwood and Klein (2002)
highlight that the visual presentation of food products, including color and packaging design, greatly influences
consumer choice. A well-designed package that showcases the quality and freshness of Banisil crackers can
draw more attention, while vibrant colors and unique shapes can enhance the product's visual appeal in a
competitive market.
Finally, the concept of innovation in food products emphasizes the need to adapt to changing consumer
preferences and market trends (Grunert, 2006). By exploring new ingredients, flavors, and packaging options,
manufacturers can create exciting products that resonate with consumers. This focus on innovation not only
enhances the overall consumer experience but also helps maintain the cherished qualities of traditional snacks
like Banisil crackers.

SUMMARY OF FINDINGS, CONCLUSION AND RECOMMENDATIONS
This study assessed the acceptability of Banisil crackers fortified with green mussel shell powder in Tanauan
Municipality. The majority of respondents were young adults (18-25 years old), with a higher percentage of
females. Sensory evaluation revealed positive feedback across appearance, aroma, taste, and texture, with the 5%
shell powder formulation receiving the highest overall acceptability due to its balanced visual appeal, flavor, and
texture.
Significantly, incorporating green mussel shell powder substantially increased the calcium content of the
crackers to approximately 396 mg per serving, enhancing their nutritional value. This fortification also
contributed to extended shelf life by reducing water activity and maintaining sensory qualities during storage.
Furthermore, the study demonstrated the high acceptability and improved nutritional profile of Banisil crackers
fortified with green mussel shell powder. The 5% formulation is recommended for its optimal balance of sensory
appeal and nutritional enhancement. Further research could explore consumer preferences across a wider age
range and investigate the potential for scaling up production and distribution.
Conclusion
This study concluded that adding green mussel shell powder significantly improved the nutritional profile of
Banisil crackers without negatively impacting sensory quality, especially at the 5% level. Sensory attributes,
particularly appearance, aroma, and texture, proved crucial in determining consumer acceptance.
The successful combination of traditional processing methods with modern formulation techniques resulted in a
sustainable and nutritious snack that appealed to consumers. The utilization of shell waste not only enhanced
nutritional value, but also promoted sustainable practices and waste reduction.
In summary, the findings support the development and production of a fortified Banisil cracker as a nutritious
and sustainable food product.
Recommendations
In order to enhance the product and promote its acceptance, the following recommendations are suggested:
1. Standardize processing techniques to ensure uniformity in product appearance, flavor, and texture and
explore advanced packaging solutions to extend shelf life and to preserve quality.
2. Highlight the health benefits, especially increased calcium content and environmental sustainability, in
marketing efforts and promote the product through health-focused and local markets.
3. Conduct wider consumer testing across different age groups, socioeconomic classes, and locations to
gain broader feedback and refine the formulation to meet diverse preferences.
4. Develop product variations (e.g., flavored crackers with cheese, garlic, or herbs) to cater to varying
consumer tastes and expand market reach.
5. Collaborate with local farmers and fisherfolk to source Banisil and Malunggay sustainably, ensuring
community livelihood support and long-term supply.
6. Pursue product certification and compliance with food safety and nutritional labeling standards (e.g.,
FDA approval) to enhance consumer trust and expand distribution.
7. Explore commercial distribution channels such as supermarkets, online marketplaces, school canteens,
and local pasalubong centers to increase accessibility and visibility.
