Hydrogen Oxidizing Bacteria

There is an urgent need for sustainable protein supply routes with low environmental footprint. Recently, the use of hydrogen oxidizing bacteria (HOB) as a platform for high quality microbial protein (MP) production has regained interest. This study aims to investigate the added value of using conditions such as salt and temperature to steer HOB communities to lower diversities, while maintaining a high protein content and a high quality amino acid profile. Pressure drop and hydrogen consumption were measured for 56 days to evaluate autotrophy of a total of six communities in serum flasks. Of the six communities, four were enriched under saline (0.0, 0.25, 0.5 and 1.0 mol NaCl l−1) and two under thermophilic conditions (65°C). Five communities enriched for HOB were subsequently cultivated in continuously stirred reactors under the same conditions to evaluate their potential as microbial protein producers. The protein percentages ranged from 41 to 80%. The highest protein content was obtained for the thermophilic enrichments. Amino acid profiles were comparable to protein sources commonly used for feed purposes. Members of the genus Achromobacter were found to dominate the saline enrichments while members of the genus Hydrogenibacillus were found to dominate the thermophilic enrichments. Here we show that enriching for HOB while steering the community toward low diversity and maintaining a high quality protein content can be successfully achieved, both in saline and thermophilic conditions. IMPORTANCE Alternative feed and food supply chains are required to decrease water and land use. HOB offer a promising substitute for traditional agricultural practice to produce microbial protein (MP) from residual materials and renewable energy. To safeguard product stability, the composition of the HOB community should be controlled. Defining strategies to maintain the stability of the communities is therefore key for optimization purposes. In this study, we use salt and temperature as independent conditions to stabilize the composition of the HOB communities. Based on the results presented, we conclude that HOB communities can be steered to have low diversity using the presented conditions while producing a desirable protein content with a valuable amino acid profile.

The future of nutrition in Colombia, and perhaps in other developing countries, will depend in large part on the ability of food technology to take full advantage of the food sources available in the country and to adapt and develop new products that will vary and complement the diets of the majority of the population at a low cost. The objective of this study was to evaluate the protein quality of rice-based drinks fortified with bovine and porcine blood plasma. Six treatments were prepared with different levels of fortification (14.5%, 18.5% and 29%). The effects of the plasma type and the addition levels on the protein content, the amino acid profile, and the in vitro digestibility of the drinks were observed. The AOAC method was employed for the determination of the protein content; the amino acid profile was created using HPLC. The protein digestibility was determined by subjecting a dispersion of the drink to the action of a multi-enzymatic solution. The protein content increased with the level of fortification. The drinks fortified with bovine plasma (104%) and porcine plasma (89%) presented a better protein quality index than the unfortified drink. The digestibility of the fortified drinks did not demonstrate significant improvements in comparison with the unfortified drink. The chemical score of the drinks fortified with porcine plasma (71.6) and bovine plasma (78.5) showed that the latter had the best nutritional quality.

Serra Da Estrela Cheese

The objective of this study is to elaborate Serra da Estrela cheese with sheep's milk concentrate by ultrafiltration and characterize it in relation to protein, yield, proteolysis, amino acid profile, and acceptability. The cheese elaborated with concentrate milk (F2) presented an increase of 17% yield, and protein content was 2 times higher than cheese without concentrate milk (F1). On the 30thday of storage F2 presented an increase of the amino acids and also of proteolysis extension and depth index in relation to the 1st day. Also presented better sensorial characteristic in relation to F1. Were observed positive correlations (>0.85) between acceptability in relation to protein, depth index, extensionand extension index, valine, methionine, serine, phenylalanine aspartic acid, valine andproline. Cheese elaborated with concentrate milk and coagulated with thistle flower is one alternative to increase cheese yield with differential sensorial characteristics.

The Impact

Quinoa cultivation has been expanded around the world in the last decade and is considered an exceptional crop with the potential of contributing to food security worldwide. The exceptional nutritional value of quinoa seeds relies on their high protein content, their amino acid profile that includes a good balance of essential amino acids, the mineral composition and the presence of antioxidants and other important nutrients such as fiber or vitamins. Although several studies have pointed to the influence of different environmental stresses in certain nutritional components little attention has been paid to the effect of the agroecological context on the nutritional properties of the seeds what may strongly impact on the consumer food’s quality. Thus, aiming to evaluate the effect of the agroecological conditions on the nutritional profile of quinoa seeds we analyzed three quinoa cultivars (Salcedo-INIA, Titicaca and Regalona) at different locations (Spain, Peru and Chile). The results revealed that several nutritional parameters such as the amino acid profile, the protein content, the mineral composition and the phytate amount in the seeds depend on the location and cultivar while other parameters such as saponin or fiber were more stable across locations. Our results support the notion that nutritional characteristics of seeds may be determined by seed’s origin and further analysis are needed to define the exact mechanisms that control the changes in the seeds nutritional properties.

Lele dumbo merupakan salah satu komoditas penting perikanan budidaya di Indonesia. Perkembangan pengolahan ikan sekarang lebih variatif seperti pengolahan menjadi dendeng. Penambahan asap cair pada proses pembuatan dendeng dapat meningkatkan keawetan dendeng serta memberikan karakteristik sensori. Tujuan penelitian ini adalah untuk mengetahui pengaruh penambahan konsentrasi asap cair yang berbeda terhadap kualitas dendeng. Rancangan percobaan yang digunakan adalah RAL (Rancangan Acak Lengkap). Perlakuan meliputi penambahan asap cair 0% sebagai kontrol, 1%, 3%, dan 5%. Parameter uji yang diamati adalah profil asam amino, kadar air, kadar protein, kadar fenol serta uji hedonik (kenampakan, bau, rasa, dan tekstur). Hasil penelitian menunjukkan bahwa dendeng dengan penambahan asap cair tetap memiliki asam amino yang lengkap. Lisin dan leusin dominan pada asam amino esensial dengan nilai 39702,77 - 51736,24 mg/kg, serta pada asam amino non esensial asam glutamat mendominasi dengan nilai 59915,6 - 64478,57 mg/kg. Perbedaan konsentrasi asap cair pada dendeng giling ikan lele dumbo memberikan pengaruh yang nyata terhadap penurunan kadar air, kenaikan protein dan fenol serta hedonik dendeng. Semakin besar konsentrasi yang digunakan, dendeng tidak diterima oleh panelis (p < 0,05). Catfish is one of nutritionally important aquaculture species in Indonesia. Nowadays, the development of its processed method becomes more various such as the production of jerked meat. Addition of liquid smoke could increase shelf life of catfish and give sensory characteristics. This study aimed to determine the effect addition liquid smoke with different concentration on quality characteristics of jerked meat. The research method used Completely Randomized Design (CRD) with four treatments such as addition of 0% liquid smoke as control, 1%, 3%, and 5%. Parameters test observed are amino acid profiles, moisture content, protein content, and phenol content also hedonic test. Jerked meat processed with liquid smoke still have a complete amino acid . Lysine and leucine dominated on essential amino acid with range 39702,77 – 51736,24 mg/kg, while glutamic acid dominated on non essential amino acid with range 59915,6 – 64478,57 mg/kg. Meanwhile, addition of liquid smoke gave a significantly different to the moisture content, protein content, phenol content also appearance, odor, flavor, and texture of catfish jerked meat (p < 0,05).
