“…fluence the biological availability of nutrients, such as calcium, which is essential for bone mineralization in preterm infants. Therefore, considering the importance of human milk acidity for its nutritional quality, it should be emphasized that acidic or alkaline overloads result in metabolic acidosis or alkalosis, and its use can cause necrotizing enterocolitis in very low birth weight preterm infants [31].…”

Human milk is the ideal nutritional support for premature neonates. Considering the need for aggregating nutritional value to human milk provided to such vulnerable group of infants, human milk was concentrated by the block freeze concentration technique. The effects of freeze concentration on the physicochemical properties, the efficiency of the process, color parameters, and the density and dynamic viscosity of human milk were assessed. The freeze concentration technology was used to successfully concentrate human milk to a factor equal to 180.48% and 72% of total solid retention in the second stage of freeze concentration. The values observed in the concentrates for the biochemical properties showed that the fraction of concentrated fluid human milk of the second stage (C2) presented elevated amounts of carbohydrates, protein and energy. The elevated caloric value observed in the ice fraction of the first stage (I1) refers to the retention of lipids in it. When added to human milk, C2 and I1 may satisfy the special requisites of nutrients and energy to guarantee the growth and development of preterm neonates.

“…It is important to point out that acidified milk may not meet nutritional requirements and the acidity increase with consequent protons release from the ionization of lactic acid provoke the destabilization of soluble proteins and casein micelles. Such alterations may incite milk coagulation, increase osmolarity and alter taste and odor, as well as impede calcium availability 17 . In addition, lipolytic and proteolytic reactions increase acidity with reduced energetic and immune value of colostrum.…”

“…The acidity of raw human milk at the moment of being milked is 1 to 7° Dornic and the lipid content influences the treatable acidity 10 . Changes this parameter may cause acidity or basicity overload and consequently can cause acidosis or metabolic alkalosis, so when breastfed the newborn can develop necrotizing enterocolitis and this can be aggravated especially if the baby is LBW and premature 10,17 .…”

Objetivo: Analisar as características sociodemográficas e gestacionais e comparar a acidez do colostro de nutrizes adolescentes e idade materna avançada. Método: Estudo prospectivo transversal, que incluiu 98nutrizes adolescentes (até 18 anos) e 33 nutrizes com idade materna avançada (maior que 35) atendidas na Maternidade do Hospital Regional de Presidente Prudente. Amostras de aproximadamente 10 mL de colostro foram obtidas por meio da ordenha manual entre 48 a 72h após o parto, e armazenadas a -20oC até o processamento. A acidez foi verificada por meio da titulação e calculada em graus Dornic. A análise estatística foi realizada utilizando-se o teste de Mann-Whitney ou X2. Resultados: A mediana da idade materna das nutrizes adolescentes foi de 20 (12-24) anos, e das nutrizes com idade materna avançada foi de 37 (35-45) anos. A maioria das nutrizes adolescentes (66,3%) eram primíparas e a via de parto cesárea ocorreu em 66,7% das nutrizes em idade materna avançada. O índice de massa corpórea (IMC) gestacional foi estatisticamente maior em nutrizes com idade materna avançada (31,3±5,6 vs 26,06±3,6, p< 0,0001). A acidez do colostro das nutrizes nos extremos da idade reprodutiva não apresentou diferença significativa entre os grupos de nutrizes. Conclusão: As características sociodemográficas e gestacionais de adolescentes e mães com idade materna avançada evidenciam heterogeneidade dessas populações e consequentemente, atendimento e condutas específicas devem ser aplicados a cada uma. A constituição do colostro em caiseina e proteinas apresentou-se constante, independente da idade materna.

Organic wastes, including cheese whey, are generated in greater quantities each year, which require management that has economic and social implications. Current treatments of cheese whey do not allow for its complete degradation or utilization. In this context, black soldier fly larvae (BSFL) promise to degrade a variety of wastes while generating and accumulating value‐added products such as protein, fat that can be transformed into biodiesel, and fertilizer can be obtained from their residues. In this work, the aim was to evaluate the cultivation of BSFL as a biological treatment for the revaluation process of cheese whey, as well as the composition of the larvae and residue (FRASS) obtained for the subsequent extraction of value‐added products such as fat or protein. It was observed that cheese whey did not affect the growth of the larvae, on the contrary, it increased it (final weight of = 0.252 ± 0.003 g). The larvae biomass was composed of mainly of lipids (42.48 ± 1.26% dry matter) and protein (34.98 ± 0.72% dry matter). A fatty acid profile was also performed, which confirms that, due to their composition (Saturated fatty acids = 262.91 ± 34.81 mg/g; monounsaturated fatty acids = 85.29 ± 19.64 mg/g; polyunsaturated fatty acids = 63.68 ± 11.33 mg/g), these accumulated lipids can be extracted for biodiesel production. This is the first approach to the treatment and utilization of cheese whey through insects.
