Meat industries utilize plant material such as celery in cured meat products. Extraction of valuable bioactive compounds, nitrates and nitrites often involves processes that increase cost or lack sustainability. Thus, this study investigated the effect of ball-milled celery powders (CP) on the physicochemical, antioxidant, and antimicrobial properties along with curing efficiency in comminuted meat product. Pork sausages loaded with CPs with different average particle sizes: 265 ㎛ (T1), 68 ㎛ (T2) and 7 ㎛ (T3) were compared to those added without and with sodium nitrite (150 ppm). The a⁎ values were increased for sausages with larger particle size. The L⁎ values decreased for all CPs. Residual nitrite for all particle sizes increased in the earlier stages and decreased at the end of storage period. The curing efficiency also increased for larger size particles with an increase until day 9 followed by a gradual decrease. Superfine CP had a tendency to improve the antioxidant activities. The antimicrobial activity of CPs was not comparable with nitrite added sausages. The textural parameters remained unaffected by particle size. Thus, instead of extracts or juices, micronized CPs could be used to improve the antioxidant activities and curing efficiency of label friendly reformulated meat products.

Objective: The study was designed to investigate the effects of restraint method, restraint duration, and body weight on stress-linked hormones (corticosterone, adrenaline, and noradrenaline), blood biochemical (namely glucose and lactate), and the meat quality in broiler chickens. Methods: A total of 120 male broiler chickens (Cobb 500) were assigned to a $2{\times}3{\times}2$ factorial arrangement in a completely randomized design using two restraint methods (shackle and cone), three durations of restraint (10, 30, and 60 s), and two categories of live body weight ($1.8{\pm}0.1kg$ as lightweight and $2.8{\pm}0.1kg$ as heavyweight). Results: Irrespective of the duration of restraint and body weight, the coned chickens were found to have lower plasma corticosterone (p<0.01), lactate (p<0.001), lower meat drip loss (p<0.01), cooking loss (p<0.05), and higher blood loss (p<0.05) compared with their shackled counterparts. The duration of restraint had significant effects on the meat initial pH (p<0.05), ultimate pH (p<0.05), and yellowness (p<0.01). The lightweight broilers exhibited higher (p<0.001) blood loss and lower (p<0.05) cooking loss compared to the heavyweight broilers, regardless of the restraint method used and the duration of restraint. However, the interaction between the restraint method, duration of restraint, and body weight contributed to differences in pre-slaughter stress and meat quality. Therefore, the interaction between the restraint method and the duration of restraint affected the meat shear force, lightness ($L^*$) and redness ($a^*$). Conclusion: The duration of restraint and body weight undoubtedly affect stress responses and meat quality of broiler chickens. Regardless of the duration of restraint and body weight, the cone restraint resulted in notably lower stress, lower meat water loss, and higher blood loss compared to shackling. Overall, the findings of this study showed that restraint method, duration of restraint, and body weight may affect the stress response and meat quality parameters in broilers and should be considered independently or interactively in future studies.

Plant-based meat analogues, edible insects, and cultured meat are promising major meat alternatives that can be used as protein sources in the future. It is also believed that the importance of meat alternatives will continue to increase because of concerns on limited sustainability of the traditional meat production system. The meat alternatives are expected to have different roles based on their different benefits and limitations. Plant-based meat analogues and edible insects can replace traditional meat as a good protein source from the perspective of nutritional value. Furthermore, plant-based meat can be made available to a wide range of consumers (e.g., as vegetarian or halal food products). However, despite ongoing technical developments, their palatability, including appearance, flavor, and texture, is still different from the consumers' standard established from livestock-based traditional meat. Meanwhile, cultured meat is the only method to produce actual animal muscle-based meat; therefore, the final product is more meat-like compared to other meat analogues. However, technical difficulties, especially in mass production and cost, remain before it can be commercialized. Nevertheless, these meat alternatives can be a part of our future protein sources while maintaining a complementary relationship with traditional meat.

본 연구는 말레이시아 무슬림의 인삼 및 홍삼제품에 대한 인식과 태도 및 이용실태를 이해하기 위하여 실시되었다. 웹 기반 설문조사방법을 이용하여 말레이시아에 거주하는 성인 남녀 무슬림(n=200)을 대상으로 인삼·홍삼제품의 인지수준, 선호도와 선호요인, 효능에 대한 인지도, 구매현황 및 만족도 등을 조사하였다. 연구결과 말레이시아 무슬림의 인삼·홍삼제품 인지도는 각각 50%, 40%정도로 나타났다. 특히, 인삼·홍삼제품에 대한 인지도는 말레이시아 여성 또는 기혼 소비자에서 상대적으로 높았다. 섭취 경험이 가장 높게 나타난 제품유형은 인삼커피, 캔디 및 초콜릿유형이었으며, 특히 인삼커피는 40~50대, 기혼자가 상대적으로 많았다. 전체 응답자의 75%는 인삼·홍삼제품의 효능에 대하여 알거나 들어본 적이 있었으며, 특히, 40-50대에 비해 20-30대가 섭취하는 이유는 건강증진, 기분전환, 주위권유 등이 주요하며, 방송이나 지인추천을 통하여 효능을 알았고, 피로개선, 면역력 증진, 고혈압개선 효능에 대한 인지도가 높게 나타났다. 인삼·홍삼제품의 건강증진효능, 구매편의성, 맛과 향에 대한 만족도는 높았지만 가격이나 포장규격은 개선할 부분으로 나타났다. 지인 추천의향(82.6%)과 지속구입의향(83.5%)은 모두 높은 편이었다. 결론적으로 할랄 인삼·홍삼제품에 대한 말레이시아 소비자의 관심과 수요를 확인할 수 있었으며 향후 인삼·홍삼제품의 인지도를 향상시킬 수 있는 전략적인 제품개발과 마케팅이 필요하다고 판단된다.
