Effects of Vegetable Proteins on Hypercholesterolemia and Gut Microbiota Modulation.

Risk assessment tools, i.e., validated risk prediction algorithms, to estimate the patient’s 10-year risk of developing cardiovascular disease (CVD) should be used to identify high-risk people for primary prevention. Current evidence confirms that appropriate monitoring and control of risk factors either reduces the likelihood of CVD or slows down its progression. It is thus crucial that all health professionals make appropriate use of all the available intervention strategies to control risk factors: from dietary improvement and adequate physical activity to the use of functional foods, food supplements, and drugs. The gut microbiota, which encompasses 1 × 1014 resident microorganisms, has been recently recognized as a contributing factor in the development of human disease. This review examines the effect of both some vegetable food components belong to the “protein food group” and the underexploited protein-rich hempseed on cholesterolemia and gut microbiota composition.

Directed Evolution of Saccharomyces cerevisiae for Increased Selenium Accumulation.

Selenium-enriched yeast (selenium yeast) are one of the most popular sources of selenium supplementation used in the agriculture and human nutritional supplements industries. To enhance the production efficiency of selenium yeast, we sought to develop a method to identify, and ultimately select for, strains of yeast with enhanced selenium accumulation capabilities. Selenite resistance of four genetically diverse strains of Saccharomyces cerevisiae was assayed in various conditions, including varying carbon sources, nitrogen sources, and phosphate amounts, and they were correlated with selenium accumulation in a commercially relevant selenium-containing growth medium. Glycerol- and selenite-containing media was used to select for six yeast isolates with enhanced selenite resistance. One isolate was found to accumulate 10-fold greater selenium (0.13 to 1.4 mg Se g−1 yeast) than its parental strain. Glycerol- and selenium-containing medium can be used to select for strains of yeast with enhanced selenium accumulation capability. The methods identified can lead to isolation of industrial yeast strains with enhanced selenium accumulation capabilities that can result in greater cost efficiency of selenium yeast production. Additionally, the selection method does not involve the construction of transgenic yeast, and thus produces yeasts suitable for use in human food and nutrient supplements.

RELAÇÃO DA INFRAESTRUTURA DA PROPRIEDADE E ALIMENTAÇÃO DOS ANIMAIS NA OCORRÊNCIA DE LEITE INSTÁVEL NÃO ÁCIDO NO PLANALTO NORTE DE SANTA CATARINA

Resumo O teste do álcool é amplamente utilizado na recepção dos laticínios para a verificação da estabilidade do leite cru. O leite que não é estável no teste e não apresenta acidez elevada é definido como leite instável não ácido (LINA). A sua ocorrência tem característica multifatorial e pode estar relacionada ao manejo nutricional inadequado. Este estudo objetivou avaliar a influência da infraestrutura da propriedade e da alimentação dos animais sobre a ocorrência de LINA. A infraestrutura foi caracterizada através de questionário guia semiestruturado. Analisou-se a composição centesimal do leite das propriedades, resistência ao teste do álcool, acidez titulável e o pH. Foram consideradas LINA as amostras que precipitaram em concentração de álcool menor ou igual a 72%, com acidez e pH normais. Nos alimentos coletados, determinou-se o teor de fibra em detergente neutro. Os dados foram avaliados através de análise fatorial e de agrupamento utilizando o pacote estatístico SAS. O uso de suplementos alimentares volumosos e concentrados, com consequente melhoria da produtividade animal e maior teor de lactose no leite foi relacionado com menor ocorrência de LINA nas condições estudadas. A ocorrência de LINA apresentou pouca relação com a infraestrutura das propriedades e com a estação do ano.

A New Method to Prevent Unintentional Child Poisoning.

Unintentional child poisoning represents an increasingly important health issue in the United States and worldwide, partially due to increased use of drugs and food supplements. Biometric authentication is complex for pill bottles, but we propose a new method of user identification using touch capacitance during bottle-opening attempts. A smart pill bottle could generate an immediate warning to deter a child from opening the bottle and send an alert to parents/guardians. In this paper, we present principle of operation and implementation of a prototype "safe bottle We present the results of pilot testing with 5 adults and 3 children using support vector machine (SVM) and neural network (NN). From 232 bottle-opening events, our optimized NN generated no false detections of children as adults and four false detections of adults as children. Preliminary results indicate that smart pill bottles can be used to reliably detect children trying to open pill bottles and reduce risk of child-poisoning events.

Impact of inherent aspects of body image, eating behavior and perceived health competence on quality of life of university students.

The aim of this study was to assess the impact of inherent aspects of body image, eating behavior and perceived health competence on quality of life of university students. Participants completed the instruments Body Shape Questionnaire (reduced version, BSQ-8B), Male Body Dissatisfaction Scale (reduced version, MBDS-R), Three-Factor Eating Questionnaire (reduced version, TFEQ-18), Perceived Health Competence Scale (bifactorial version, PHCS-B), World Health Organization Quality of Life Questionnaire-Short Form (WHOQoL-bref) and a questionnaire for characterization of sample. Psychometric properties of instruments were previously evaluated by confirmatory factor analysis. A hypothetical model for each sex was developed and tested. In both model surveys the aspects of the body image (BSQ-8B: body shape concern; MBDS-R: musculature and general body appearance), of eating behavior (TFEQ-18: cognitive restriction, emotional eating, and uncontrolled eating) and of the perceived health competence (PHCS-B: expectations of achieving the desired health results and competence in health behaviors) were used as direct predictors on quality of life (WHOQoL-bref). The variables age, medication use for body change, food supplement use for body change, and body mass index (BMI) were inserted in the aspects of the body image. The variables course shift, initial expectation regarding the course, self-reported performance in the course, concomitant work activities to studies, and economic class were inserted into the quality of life. The model surveys were evaluated using structural equation modeling. A level of significance of 5% was used. A total of 2,198 university students (female = 63.5%), including 1,151 Brazilians and 1,047 Portuguese, participated of study (locally representative samples). The average age of women was 20.8 ± 2.4 years and of men was 21.3 ± 3.3 years. The psychometric properties of the instruments were adequate, except for the PHCS, which was adjusted for each sex. The models presented variance explained of 54% and 49% for women and men, respectively. In both sexes, the students’ perceived health competence and academic variables contributed significantly to their quality of life, and age, BMI, and medication and supplement use were significant factors relating to how a student views his or her body image. Women's quality of life was associated with body shape concern and emotional eating aspects. Men's quality of life was associated with general body appearance and cognitive restriction aspects. These results can be used to create and implement educational programs to improve quality of life of university students.

Design and Feasibility of a Safe Pill Bottle

Ubiquitous intelligence of Internet of Things (IoT) objects and new sensors provide innovative solutions for a variety of health issues. Unintentional child poisoning represents an increasingly important health issue worldwide, partially because of an increase in the use of drugs and food supplements. Although child-resistant bottle caps have probably saved many lives, they are not foolproof and do not provide warnings for parents and caregivers when children try to access the bottles. In this paper we present a design, implementation, and feasibility analysis of an intelligent “safe pill bottle” that can identify when a child is trying to open a bottle and then generate an immediate warning to deter a child from opening the bottle and send alerts to parents/guardians. The bottle controller uses capacitive sensing to identify the class of user. We present the results of pilot testing with eight adults and eight children using neural networks (NN). With 474 bottle-opening events, our NN had 96.4% accuracy of predicting whether the user was a child or an adult. Preliminary results demonstrate that smart pill bottles may be an effective tool to prevent unintentional child poisoning.

Food Supplements - Considerations in Medical Practice

Food supplements in Europe are subject to food safety legislation. They should not be confused with pharmaceuticals. Rather, they are foods, whose purpose is to supplement the normal diet, and represent concentrated sources of nutrients (i. e. vitamins and minerals, including trace elements) or other substances with a nutritional or physiological effect. Nevertheless, it should be kept in mind that consumers may in some cases use food supplements for the purpose of self-medication. In the context of anamnesis, physicians should specifically question their patients about the use of food supplements. This can be of significant relevance for evaluation of possible undesirable or adverse effects, influences on laboratory parameters, or interactions with pharmaceuticals, which may be due to consumption of certain products that are marketed as food supplements. Furthermore, education of patients with respect to the possible benefits and risks related to the use of vitamins, minerals and other constituents of food supplements should be intensified.

Habits and beliefs related to food supplements: Results of a survey among Italian students of different education fields and levels.

The increasing availability of food supplements, aggressive media advertising, and common beliefs that these substances have only positive effects on health and sport performance indicate a need for continuous monitoring of this phenomenon. The aim of this study was to investigate the habits and beliefs related to diet supplementation among medical, health professional, and other university/high school students by means of a cross-sectional anonymous survey online. Among the respondents aware of supplements, 37.4% were taking or had taken them in the past. Food supplement use was more common among university students (in particular, those in health professional graduate courses) than high school students. Individual sport practice, rather than team sport, was associated with higher likelihood of food supplement use. Multivitamins were most commonly used, while weight-loss formulations were the least popular. Strikingly, filling nutrient gaps was statistically not considered the main reason for taking food supplements. Instead, they were used to enhance mental performance or enhance well-being. There was statistical evidence that students not enrolled in health or medical professional studies strongly agreed more often than medical students that taking food supplements prevents illness. These results indicate a striking difference between the evidence-based and personal reasons for food supplement use. Arguably, it calls for an improvement in education about diet supplementation and a change in attitude of health care providers to its implementation.

The PlantLIBRA consumer survey: Findings on the use of plant food supplements in Italy

BackgroundFood supplements, and in particular those containing botanicals (plant food supplements, PFS), have in recent decades been of great interest both to consumers and to food/pharmaceutical industries.ObjectivesThe aim of this paper is to examine replies by Italian consumers to the PlantLIBRA consumers' survey in order to: 1) assess the behaviour of an Italian population with respect to the use of PFS, and to compare it with that of other 5 countries involved in the whole survey; 2) identify different habits in the 4 Italian cities selected according to their geographical distribution; 3) collect independent information on the actual intake of PFS and consumers' behaviour.Subjects/setting397 Italian consumers enrolled, 187 males (49.5%) and 191 female (50.5%). The distribution of subjects among the 4 cities included was: Milan 99; Venice 90; Rome 96 and Catania 96.ResultsThe interest in PFS in Italy is high, the prevalence of "regular" consumers being 22.7%. Some differences were observed between the 4 cities involved: the pattern of use during the year was specific to each city; consumers in Milan reported reasons to use PFS significantly different from those in the whole Italian sample and did not indicate supermarkets as an important place of purchase; respondents from Rome and Catania more frequently used family doctors and pharmacists as a source of recommendation. Some significant difference among cities, sex and age groups were observed when the most frequently used botanicals were ranked.ConclusionsThe results provide new insights on the socio-economic characteristics and lifestyle of Italian PFS consumers, on their reasons for and pattern of use, and on their behaviour and expectations. The value of this information is not restricted to the specific country (Italy) but allows for a more general evaluation of the pattern of use, according to habits and geographical area.

DEMOGRAPHICS AND FACTOR ASSOCIATED WITH FOOD SUPPLEMENTS USE AMONG YOGYAKARTA POPULATION

Objective: The aim of this study was to explore the prevalence of food supplement use and the association between foods supplement use and sociodemographic factors among Yogyakarta population.Methods: A cross-sectional online questionnaire was developed and validated. A number of 933 participants completed the survey during September-December 2016. A convenience sampling technique was used. The sociodemographic characteristics and use of dietary supplements were collected. Frequency distributions were used to explore the use of food supplement. The relationship between demographic factors and dietary supplement use was conducted using pearson correlation analysis.Results: Food supplement daily use was reported by 63% of participants. A mean number of the supplement was 2.3 (SD 2.1). The advertisement was commonly the source of information about food supplement. Age, sex, monthly income, excercise, and smoking status were associated with food supplement use.Conclusion: Use of food supplements in this population was relatively high reflects that of other countries. Participants were using unreliable source of information of the benefits and risks associated with supplement consumption. Health professionals should account for dietary supplements when assessing medication. Regulating bodies and public health officers need to be aware to ensure safe practices.

Safety of pyrroloquinoline quinone disodium salt as a novel food pursuant to Regulation (EC)No258/97.

Following a request from the European Commission, the EFSA Panel on Dietetic Products, Nutrition and Allergies (NDA) was asked to deliver an opinion on pyrroloquinoline quinone disodium salt (PQQ), trade name BioPQQ™, as a novel food pursuant to Regulation (EC) No 258/97. PQQ is produced by fermentation using Hyphomicrobium denitrificans CK‐275 and purification process. PQQ has a minimum purity of 99.0%. The information provided on the composition, specifications, batch‐to‐batch variability, stability and production process of PQQ is sufficient and does not raise safety concerns. The applicant intends to market PQQ for use in food supplements for healthy adults, except pregnant and lactating women, at a maximum proposed level of consumption of 20 mg/day (corresponding to 0.29 mg/kg bw per day for a 70‐kg person). The proposed level of consumption is at least 250 times higher than the estimated background intake of PQQ occurring naturally in foods. Information on the absorption, distribution, metabolism and excretion of PQQ in animals and humans is limited. Considering the no‐observed‐adverse‐effect‐level (NOAEL) of 100 mg/kg bw per day from a 90‐day repeated dose oral toxicity study with BioPQQ™, and the maximum proposed level of consumption, the Panel concludes that the margin of exposure (of 344) is sufficient. The Panel concludes that the novel food, pyrroloquinoline quinone disodium salt (BioPQQ™), is safe under the intended conditions of use as specified by the applicant.

Cystites récidivantes : des moyens de prévention non médicamenteux

To estimate from the literature review, the interest of hygienic and behavioural measures and the use of food supplements (herbal) to prevent female urinary tract infection. Pubmed research was focused on the efficiency of prophylactic measures in recurrent cystisis management. Due to many predisposing factors such as anatomical charasteristics, hydration and lifestyle, cystisis is more common in female subjects than in male. The infection is mostly caused by uropathgenic Escherichia coli which is mostly found in the intestine. Recomendations propose a better use of antibiotics that causes undesirable side effects (such as nausea, candidiasis) and favours the development of resistant bacterial strains. Hygienic measures, good hydration, and respecting a good urinary rythm help to protect from new infectious episodes. Food supplements such as cranberry or D-mannose can also interfere with the recurrence of cystisis, by preventing the bacteria sticking to urinary tract epithelia. Their efficency is relative and seems to be dose-dependent. Better tolerated than prophylactic antibiotic treatments, they can increase times of respite. Using prophylactic treatment still have an interest, even if they are questionable. Moreover, the combination of these methods (diet and lifestyle advice) can be an alternative to long-term prophylactic medical treatment.

Rare-earth elements in human colostrum milk

Rare-earth elements (REEs) are used in a growing number of applications, and their release to environment has increased over the decades. Knowledge of REEs in human milk and factors that could possibly influence their concentration is scarce. This study evaluated the concentrations of 16 REEs (Ce, Eu, Er, Gd, La, Nd, Pr, Sc, Sm, Dy, Ho, Lu, Tb, Tm, Y, and Yb) in human colostrum milk collected from Polish women (n = 100) with the ICP-OES technique. The concentrations (mean ± SD) of Pr (41.9 ± 13.2 μg L−1), Nd (11.0 ± 4.0 μg L−1), La (7.1 ± 5.2 μg L−1), and Er (2.2 ± 0.8 μg L−1) were found above detection limits. The total mean ± SD concentration of detected REEs was 60.9 ± 17.8 μg L−1. Current smokers displayed significantly increased Nd concentrations compared to women who had never smoked. No other associations between REEs in colostrum milk and age, diet in pregnancy (food supplement use and frequency of fish, meat, and vegetable consumption) or place of living (urban/rural) were found. This study adds to general understanding of the occurrence and turnover of REEs in women and human fluids.

Safety of Ecklonia cava phlorotannins as a novel food pursuant to Regulation (EC) No258/97.

Following a request from the European Commission, the EFSA Panel on Dietetic Products, Nutrition and Allergies (NDA) was asked to deliver a scientific opinion on the safety of Ecklonia cava phlorotannins (marketed as SeaPolynol™) as a novel food submitted pursuant to Regulation (EC) No 258/97. The novel food is a phlorotannin‐rich alcohol extract of Ecklonia cava, which is an edible marine brown alga species. The information provided on the composition, the specifications, the production process and the batch‐to‐batch variability of the novel food is sufficient and does not raise safety concerns. The intention is to market the novel food as a food supplement for healthy individuals over the age of 12 years. A subchronic repeated dose oral toxicity study in rodents tested the novel food at daily doses of 0, 375, 750 and 1,500 mg/kg body weight (bw). The Panel considers the mid‐dose as the no‐observed‐adverse‐effect‐level (NOAEL) of the study. Taking into account this NOAEL of 750 mg/kg bw per day and by applying an uncertainty factor of 200, the Panel considers an intake level of 3.75 mg/kg bw per day as safe. The Panel concludes that the novel food, Ecklonia cava phlorotannins, is safe for the use in food supplements at a maximum daily intake level of 163 mg/day for adolescents from 12 to 14 years of age, 230 mg/day for adolescents above 14 years of age and 263 mg/day for adults.

Vigilance on use of drugs, herbal products, and food supplements during pregnancy: focus on fosfomycin

Purpose: Urinary tract infection (UTI) is defined as a common bacterial infection that can lead to significant morbidity such as stricture, fistula, abscess formation, bacteremia, sepsis, pyelonephritis, and kidney dysfunction with a mortality rates reported of 1% in men and 3% in women because of development of pyelonephritis. UTIs are more common in women and the 33% of them require antimicrobials treatment for at least one episode by the age of 24 years. UTIs are the most common infections observed during pregnancy and up to 30% of mothers with not treated asymptomatic bacteriuria may develop acute pyelonephritis which consequently can be associated to adverse maternal and fetal outcomes. All bacteriuria in pregnancy should be treated with antimicrobial treatments being safe for both the mother and the fetus. Approximately one every four women receives prescription of antibiotic treatment during pregnancy, nearly 80% of all the prescription medications during gestation. The use of fosfomycin to treat cystitis in pregnancy generally considered safe and effective. Even though use on antibiotics for urinary tract infections is considered generally safe for the fetus and mothers, this opinion is not based on specific studies monitoring the relationship of among urinary infections, consumption of antibiotics, and pregnancy outcomes. Materials and methods: On this basis we decided to analyze data from the database of our multicenter study PHYTOVIGGEST, reporting data from 5362 pregnancies, focusing on use of fosfomycin. Principal outcomes of pregnancy in women treated with fosfomycin were taken into consideration. Results: Women who have been treated with urinary antibiotics during the pregnancy were 183. With respect to the total number of pregnancies of our sample, these women represented the percentage of 3.49% (187/5362). Analysis of different outcomes of pregnancy such as gestational age, neonatal weight, and neonatal Apgar index did not show any significant difference. At the same time, analysis of data of pregnancy complicancies (such as urgent cesarean delivery, use of general anesthesia, need to induce labor) did not show any difference in women taking fosfomycin during pregnancy and those not taking it. Conclusions: Our data, based on a large number of pregnancies, confirm the safety use of fosfomycin use in pregnancy.

Medication and supplement use in older people with and without intellectual disability: An observational, cross-sectional study.

IntroductionUnderstanding the medication and supplement use of aging people is critical to ensuring that health service providers in primary care can optimise use of these agents. An increasing number of people with different levels of intellectual disability (ID) are living in the community and becoming for the first time substantial users of primary health care services. This, however, brings new challenges that need to be addressed at the primary health care level. We quantified the use of medicines and food supplements and described the associated patterns of morbidity in the two comparable cohorts of aging population with and without intellectual disability.MethodThis research aligned participants of 50 years and over who lived in the community from two nationally representative cohorts of older people; those with ID from the Intellectual Disability Supplement (n = 238) and those without ID (n = 8,081) from the Irish Longitudinal Study on Ageing.ResultsData showed that both medication and supplement use in the two groups was prevalent but that those with ID received more of both medications and supplements (e.g. polypharmacy was 39.0% in ID vs. 18.1% in non-ID cohort). Moreover, based on an analysis of the therapeutic groups and medications used that treatment was more intense in the ID cohort (95.8 vs. 7.0 International Non-proprietary Names per 100 participants). Supplement use was almost twice as prevalent in the ID group but substantially less diverse with only 10 types of supplements reported. Morbidity was higher in the ID group and showed a higher prevalence of neurological and mental health disorders.ConclusionThe results highlight that the burden of therapy management and the potential risks in those ageing with ID differs substantially from those ageing without ID. Understanding the medication and supplement use of people aging with intellectual disability (ID) is critical to ensuring that health service providers in primary/ambulatory care can optimise use of these agents.

The Regulatory Framework Across International Jurisdictions for Risks Associated with Consumption of Botanical Food Supplements.

Dietary supplements, including those containing botanical ingredients and botanical-derived compounds, have been marketed to consumers globally for many decades. However, the legislative framework for such products remains inconsistent across jurisdictions internationally. This study aims to compare the regulatory framework of botanical food supplements in the EU, USA, Canada, Australia, New Zealand, India, Japan, and China. The study also aims to investigate and describe safety assessment criteria for botanical food supplements where they are present in the above said jurisdictions, and attempts to analyze whether these criteria are suitable for addressing the toxicological risks associated with the use of botanical food supplement products, based on the evaluation of reported adverse effects related to botanical food supplement use as examples. Finally, this study discusses some future issues that need further attention, such as the consideration of less than lifetime exposures, potential for misidentification, and adulteration of botanical supplements by pharmacologically active substances. It is concluded that the regulatory approaches towards botanical food supplements differ significantly across jurisdictions. In addition, national authorities are increasingly considering having more regulatory oversight for such products. Further consideration of the actual impact of adverse events arising from botanical food supplement usage will be helpful in guiding such decisions.

Toxicological evaluation of neoagarooligosaccharides prepared by enzymatic hydrolysis of agar

Agar, a heterogeneous polymer of galactose, is the main component of the cell wall of marine red algae. It is well established as a safe, non-digestible carbohydrate in Oriental countries. Although neoagarooligosaccharides (NAOs) prepared by the hydrolysis of agar by β-agarase have been reported to exert various biological activities, the safety of these compounds has not been reported to date. For safety evaluation, NAOs containing mainly neoagarotetraose and neoagarohexaose were prepared from agar by enzymatic hydrolysis using β-agarase DagA from Streptomyces coelicolor. Genotoxicity tests such as the bacterial reverse mutation assay, eukaryotic chromosome aberration assay, and in vivo micronucleus assay all indicated that NAOs did not exert any mutational effects. The toxicity of NAOs in rat and beagle dog models was investigated by acute, 14-day, and 91-day repeated oral dose toxicity tests. The results showed that NAO intake of up to 5,000 mg/kg body weight resulted in no significant changes in body weight, food intake, water consumption, hematologic and blood biochemistry parameters, organ weight, or clinical symptoms. Collectively, a no-observed-adverse-effect level of 5,000 mg/kg body weight/day for both male and female rats was established for NAO. These findings support the safety of NAO for possible use in food supplements and pharmaceutical and cosmetic products.

Urban Bird Feeders Dominated by a Few Species and Individuals

The practice of garden bird feeding is a global phenomenon, involving millions of people and vast quantities of food annually. Many people engage in the practice of feeding assuming that birds gain some benefit from the food they provide, yet recent studies have revealed the potential for detrimental impacts as well. However, there is still a paucity of information on the impacts of feeding, including the ubiquity of these impacts among and within feeder-visiting species. Consistency in feeder use among birds is likely an important determinant of this. Individual birds and species that make frequent use of feeders are more likely to experience both the benefits and detrimental impacts of supplementary food. We investigated patterns of feeder use by garden birds visiting experimental feeding stations in Auckland, New Zealand, with the specific aim of determining whether use of supplementary food was consistent or variable among individuals and species. We used camera traps as well as Radio Frequency Identification (RFID) technology to examine intra- and interspecific feeder visitation patterns and to discern species associations. Eleven bird species were detected using feeding stations, however, two introduced species (house sparrow Passer domesticus and spotted dove Streptopelia chinensis) dominated visitation events. These species were present at feeders most frequently, with the largest conspecific group sizes. Significant associations were detected among a number of species, suggesting interspecific interactions are important in determining feeder use. We also found within-species differences in feeder use for all focal species, with individual variation greatest in house sparrows. Furthermore, season had an important influence on most visitation parameters. The observed individual and species-specific differences in supplementary food resource use imply that the impacts of garden bird feeding are not universal. Crucially, particularly given the avifaunal context in New Zealand, resource dominance by introduced species could have potential negative outcomes for native species conservation in cities.

Integration of protein extraction with a stream of byproducts from marine macroalgae: A model forms the basis for marine bioeconomy

The present study describes an advanced biorefinery model for marine macroalgae that assumes significant importance in the context of marine bio-economy. The method investigated in this study integrates the extraction of crude proteins with recovery of minerals rich sap, lipids, ulvan and cellulose from fresh biomass of Ulva lactuca. The protein content extracted was 11±2.12% on dry weight basis with recovery efficiency of 68.75±4.01%. The amino acid composition of crude protein fraction showed iso-leucine as the most abundant amino acid with 16.51±0.03% followed by histidine, arginine, tyrosine, serine, aspartic acid, threonine, phenyl alanine, leucine, alanine, lysine, glycine and glutamic acid (0.22±0.24%). The digestibility of protein was as high as 85.86±5.92% indicating its suitability for use in food supplements. The protein production with co-recovery of other products would not only result in effective utilisation marine macroalgal resources but also forms the basis for marine bio-economy.
