Bio-organic fertilizer production from industrial waste and insightful analysis on release kinetics

The present study has been designed to utilize industrial and agricultural solid waste for NPK (Nitrogen–Phosphorus–Potassium) bio-organic fertilizer production and its optimized use. The collagenic material of wet blue leather (WBL) from leather industry was used as nitrogen source, after H3PO4 acid-mediated chromium removal. Chicken meat-bone meal (CMBM) and rice husk ash (RHA) are abundantly available locally, had used as P, K, and Ca sources. The presence of N, P, K, Ca in the produced bio-organic NPK fertilizer were 10.76, 11.03, 3.41, 13.64, respectively as per mixing ratio of ingredients. In this study it was effect on the chili plant (Capsicum annuum L.) growth and revealed 1.15 and 1.03 fold higher plant growth, 1.40 and 1.18 fold higher total chlorophyll content than untreated soil (control), and chemical fertilizer. The liberation of fertilizers components from their source, transport of fertilizer components in the soil, and absorption in plant roots have been studied using mathematical models indicating the optimum fertilizer use for better productivity and to reduce loss of extra fertilizer and eutrophication. The formulation showed excellent water retention capability (3.2 L/kg), which might increase soil water availability to the plants and eventually reduce water demand and labour cost. DNA intercalation study proved there is no harm to use this fertilizer.

Dietary Status of Women who Gave Birth with Congenital Anomalies in Bale Zone Hospitals, Southeast Ethiopia

Objective: Congenital anomalies (CAs) are structural or functional anomalies that develop during intrauterine life and are present at birth. There has been very little knowledge on various forms of CAs as well as dietary status of women who gave birth with CAs in Southeast Ethiopia. This study, therefore, examined the types of CAs diagnosed at birth as well as the dietary status of women who gave birth with CAs in Southeast Ethiopia. Methods: An institutional-based cross-sectional study was conducted in Bale zone hospitals, Southeast Ethiopia. All women who gave birth with any form of CAs were included in the study. All births were examined by either obstetricians or emergency obstetric surgeons. Data were entered into SPSS version 21 for analysis. Descriptive statistics were computed to summarize the data. Results: In this study, anencephaly (30.9%) and spinal bifida (17.6%) were the most commonly reported form of CAs. A single case of the imperforated anus, minigocephalocele, severe spinal bifida, twin transfusion syndrome, polyhydramnios and the umbilical hernia was also diagnosed during the study period. Nearly half percent (48.5%) of women who gave birth with CAs consumed less than one meal of meat per week, and 33% of women consumed 1-3 meals of fresh vegetables per week during their pregnancy. Furthermore, the reported consumption of folic acid and intake of iron during the current pregnancy was 23.3% (95% CI: 17.2, 33.7) and 47.8% (95% CI: 32.6, 61.9), respectively. Conclusion: The incidence of CAs in the study area is high. Consumption of a range of vegetables and fruits may reduce the development of Cas; hence, educational interventions that improve women's healthy diet practices must be considered. We also recommend further studies to better understand the relationships between the dietary status of women and the incidence of CAs.

The Effect of Blood Groups and Nutritional Habits of Different Classifications of Referees on the Success of Turkish Football Management

Volunteer 247 football referees in the Turkish Professional Football Leagues were included in this study which aims to evaluate the effect of blood groups and nutritional habits of different classifications’ referees on the success of Turkish football management. After the demographic information (age, height, weight, education level and blood groups (based on their statements)) of the referees were taken, the total refereeing times, their classifications and their duration in their classifications, and their nutritional information habits were obtained with a questionnaire. Classification Trees Method was used to determine the factors affecting the success (classification) of the referees. The distribution of the blood groups of the referees did not differ significantly from the distribution of the general blood groups in our country. However, A RH + and 0 RH + blood groups were seen more frequently in the study group. It was determined that 86.7% of the referees with a service period of more than three years, whose blood groups were 0 Rh+ or 0 Rh-, were top classification assistant referees. In our study, it was determined that the classification and classification assistant referees did not acquire regular eating habits and observed that the level of nutrition knowledge increased with a rise toward the top classification. It can be said that these results indicate the need for nutrition education for football referees. Among the referees with a two-year period, 73.8% of those who skip meals and say I have no appetite/habit are working as classification referees, and 72.2% of those who say to lose weight working as assistant referees. 50% of those who eat 2 or 5 meals a day are classification assistant referees, and 66.7% of those who eat 3 or 6 meals a day are classification referees. It was seen that 66.6% of the three-year referees who were fed with meat meal, salad, dessert or pasta before the competition were classification and classification assistant referees, and 73.5% of those who were fed with food groups such as vegetable food, yoghurt, fruit, boiled meat or chicken, meat, meatballs, rice, compote were top classification assistant referees.In this study, it is thought that the factors affecting the success of the referees the most are their dietary habits and the duration of the refereeing, and some blood groups are thought to be effective on the success of the referees.

Thermal inactivation of African swine fever virus in feed ingredients.

African swine fever virus (ASFV) causes a fatal infectious disease affecting domestic pigs and wild boars. ASFV is highly stable and easily transmitted by consumption of contaminated swine feed and pork products. Heat treatment of feed ingredients is a means to minimize the risk of contamination through swine feed consumption. The objectives of this study were to determine the thermal inactivation of ASFV in non-animal and animal origin feed ingredients. The rate of thermal inactivation is represented by decimal reduction time (DT) or time required to reduce ASFV per 1 log at temperature T. The mean D60, D70, D80 and D85 of meat and bone meal (MBM), soybean meal (SBM), and maize grain (MZ) are in the ranges 5.11–6.78, 2.19–3.01, 0.99–2.02, and 0.16–0.99 min, respectively. DT is used to compare the heat resistance of ASFV in the feed ingredient matrices. The mean DT of ASFV in MBM, SBM and MZ was not statistically significant, and the heat resistance of ASFV in MBM, SBM, and MZ was not different at 60, 70, 80, or 85 °C. The multiple DT was used to develop a DT model to predict DT at various inactivation temperatures. The DT models for MBM, SBM, and MZ are log DT = − left( {frac{T}{32.08}} right) + 2.69, log DT = − left( {frac{T}{31.77}} right) + 2.55, and log DT = − left( {frac{T}{18.96}} right) + 4.01. To expand and ease the field applications, a spreadsheet predicting the DT and the inactivation time (with 95% confidence interval) from these DT models is available to download.

Eco-Friendly Alternative Disposal through the Pyrolysis Process of Meat and Bone Meal.

The capitalization of agri-food waste is essential for the sustainability of a circular economy. This work focuses on a solution to eliminate such waste, meat and bone meal (MBM), which is produced in large quantities by the food industry and is prohibited for use as animal feed under the European directives. Therefore, with the focus of converting waste to energy, the catalytic pyrolysis of MBM in the presence of mesoporous silica nanocatalysts (SBA-3 and SBA-16 materials and metallic derivates) was investigated in a home-made reactor for the production of renewable energy. The mesoporous silica materials were synthesized using relatively simple methods and then characterized in order to determine their morpho-structural characteristics. The MBM pyrolysis behavior under different experimental conditions was examined in detail, both in the presence and absence of the new catalysts. The resulting MBM-based pyrolysis products, MBMPYOILs and MBMPYGASs, were also assessed as potential alternative fuels, highlighting comparable energy values to conventional fuels. The outcomes of this investigation offer a potential pathway to the clean production of gas and oil, thus promoting the high-grade utilization of MBM waste.

A Study of Consumers’ Perceptions of Take-Out Food before and after the COVID-19 Outbreak: Applying Big Data Analysis

This study explored changes in consumers’ perceptions of take-out food before and after the onset of the COVID-19 pandemic using big data collected from social media. Using “take-out food” as a keyword, 18,544 search results were found in 2019, before the COVID-19 outbreak, compared to 20,718 search results in 2021. These keywords were analyzed using text mining, semantic network analysis, CONCOR analysis, and sentiment analysis, respectively, to understand consumers’ perception of take-out food. Using text mining, in 2019, “dining-out” was the most frequent search term associated with take-out food, followed by packing, famous restaurant, family, delicious, menu, and available. In 2021, “dining-out” was again the most popular keyword, followed by packing, famous restaurant, delivery, family, delicious, available, and Corona. A semantic network analysis showed that, in 2019, four categories emerged: delicious, meat, satisfaction, and lunchbox. The same analysis showed that, in 2021, the categories were delicious, meat, good, and home meal. These findings suggest that, after COVID-19, take-out food began to be recognized as a daily meal that can replace home-cooked meals. According to the sentiment analysis, the number of positive keywords decreased by 4.03% after COVID-19, while the number of negative keywords increased at the same rate; regarding the increase in negative keywords, such as sadness, disgust, and fear, since the emergence of COVID-19, consumers’ anxiety about eating out due to the virus was observed. This study can be useful by providing core data and an analysis method necessary for food service companies’ business activities and decision making related to take-out amid consumers’ rapidly changing needs for the dining-out environment caused by COVID-19.

PSXI-11 Oxidation Analysis on Chicken Meat Meals Composition, Aromatics, and Palatability: A Novel Aromatic Palatability Trial Utilizing Labrador Retrievers, Hercules Enose Ufgc, Spme, and Broad Spectrum Gcms

Abstract Even the highest quality ingredients undergo oxidative stresses during manufacturing processes, increasing the nutrition delivery challenges facing large-scale feed manufacturing. In this study we investigate the impact of increasing peroxide values (PV) in the chemical composition in rendered chicken meal (CM) and chicken by-product meal (CB). To determine canine acceptance, working Labrador Retrievers (20 male; 20 female) were used in a preliminary novel aromatic palatability test as well as a traditional two-pan palatability test. PV sample levels ranged from < 10-200 (CB or CM Sample identification: 1.~ < 10, 2.~20-50, 3.~50-100, 4.~100-200). Results indicate that dogs preferred reduced peroxide values in both aromatic (p= < 0.05) and traditional 2-pan palatability trials (p= < 0.05). Preference testing results correlated with extensive physical and chemical data obtained using a Heracles Electronic Nose ultra-fast gas chromatography (UFGC), solid-phase micro-extraction (SPME), and gas chromatography-mass spectrometry (GC-MS). The broad-spectrum analysis utilized solid-phase micro-extraction (SPME) and gas chromatography-mass spectrometry (GC-MS) to identify 177 nonpolar compounds, 340 polar compounds, and 457 volatile compounds. The overall composition did not vary; however, individual compounds had strong linear correlations with peroxide value. In chicken by-product meal samples, 38 compounds were linearly correlated; in chicken meals, 27 compounds were identified (r2>0.90). These data: 1) introduces novel quality control markers for further research and showcases the potential for greater accuracy by developing product specific markers; 2) confirms that the chemical differentiation between peroxide values went beyond lipid oxidation and highlighted multiple compounds of interest for further study; and 3) emphasizes greater levels of peroxide in pet foods have unfavorable palatability. This research was funded by the Fats and Protein Research Foundation.

Meat and bone meal stimulates microbial diversity and suppresses plant pathogens in asparagus straw composting.

Meat and bone meal (MBM), as slaughterhouse waste, is a potential biostimulating agent, but its efficiency and reliability in composting are largely unknown. To access the MBM application to the composting process of asparagus straw rice, we followed the composting process for 60 days in 220-L composters and another 180 days in 20-L buckets in treatments applied with MBM or urea. The microbial succession was investigated by high-throughput sequencing. Compared with urea treatments, MBM addition stabilized pH and extended the thermophilic phase for 7 days. The germination index of MBM treatments was 24.76% higher than that of urea treatments. MBM also promoted higher microbial diversity and shifted community compositions. Organic matter and pH were the most significant factors that influence the bacterial and fungal community structure. At the genus level, MBM enriched relative abundances of organic matter-degrading bacteria (Alterococcus) and lignocellulose-degrading fungi (Trichoderma), as well as lignocellulolytic enzyme activities. Notably, MBM addition decreased sum abundances of plant pathogenic fungi of Phaeoacremonium, Acremonium, and Geosmithia from 17.27 to 0.11%. This study demonstrated the potential of MBM as an effective additive in asparagus straw composting, thus providing insights into the development of new industrial aerobic fermentation.

Effects of Palm Kernel Meal in Diets of Layer KUB Chicken

The purpose of this study was to investigate the effects of different levels of palm kernel meal (PKM) on diets of layer KUB (Kampung Unggul Balibangtan) chicken. Local feed was included in the various diets of PKM at levels of 0% (T1), 10% of PKM (T2) and 20% of PKM (T3). This research was conducted in 2019 at the beginning of layer period. One hundred and forty-four 22-week-old layer birds were selected from a flock and randomly allocated to three treatments with 3 replicates of the diet feeds introduced. Feed intake and egg production were determined using the SPSS Software. The increase in PKM levels had no effect on feed intake and egg production (p>0.05). The egg production in each treatment were 65.39%, 60.67 % and 62.50%. PKM applied in T3 (20%) did not affect the egg production in KUB chickens due to low crude fibre (4.64%). The price of feed in T1, T2 and T3 were IDR 6,000, IDR 5,250 and IDR 4,500 respectively. With the difference in PKM feed prices of IDR 1,500 compared to commercial feed, this is expected to reduce the cost of KUB chicken production.
 Keywords: Palm kernel meal (PKM), layer KUB chicken, production

Replacement of fishmeal using poultry-based protein sources in feeds for pikeperch (Sander lucioperca, Linnaeus, 1758) during grow out phase

A 61-day growth experiment was carried out to evaluate the potential of a poultry-based protein (PBP) comprising of feather meal (FeM) and poultry meat and bone meal (PMBM), as a fishmeal (FM) substitute in diets of juvenile pikeperch (Sander lucioperca, L.). Pikeperch (initial body weight 113.12 g) were randomly distributed in groups of 250 fish in twelve 1.8 m3 circular recirculating aquaculture system (RAS) tanks, and fed four isonitrogenous (52% crude protein), isolipidic (17% crude lipid), and isocaloric (21.80 KJ/g energy) experimental diets. The feeds contained FM as the primary protein source (PBP0) or PBP replacing 20 (PBP20), 40 (PBP40), or 60% (PBP60) of the FM. Based on appetite and calculated uneaten feed, the feeding rate was initially set at 1.5% and subsequently reduced to 1% of the total tank biomass towards the end of the study. At the end of the experiment, the average feed intake ranged from 1.93 to 2.00 g/fish/day (p > 0.05). No adverse effects on growth and feed efficiency were observed in fish fed diets PBP0, PBP20, and PBP40. Particularly, the final body weight (FBW) (248.73, 240.11 g), feed conversion ratio (FCR) (0.86, 0.91), specific growth rate (SGR) (1.29, 1.35%/day), and protein efficiency ratio (PER) (2.20, 2.12) of fish fed PBP20 and PBP40 were not significantly different from the control PBP0 whose values ranged from 248.11 g, 0.89, 1.27%/day, and 2.18, respectively (p > 0.05). In all treatments, the condition factor (k) (1.31 to 1.33), hepatosomatic index (HSI) (2.35 to 2.70%), visceral somatic index (VSI) (6.87 to 7.19%), and whole-body composition of crude protein (57.77–58.28%) and crude lipid (23.85–26.85%) were not significantly influenced by the dietary PBP inclusion level (p > 0.05). However, whole-body ash content was significantly higher in PBP60 (14.66%) compared to the other treatments (12.57–14.43%) (p < 0.05). Based on the results from this study, up to 40% of FM can be replaced by PBP in diets for pikeperch juveniles without compromising growth performance and feed utilization.

Технология изготовления белковых кормовых смесей для гидробионтов на основе культивируемых червей Eisenia fetidа и Dendrobena Veneta с применением технологии лиофильной сушки

The technology being developed for the production of a feed mixture based on the biomass of a cultivated worm is aimed at improving factory feeds by adding an additional volume of protein, thereby increasing the nutritional value of the feed, eliminating the need to buy a specific feed of greater nutritional value, providing the opportunity to supplement feeds less saturated with protein components. Also, the technology being developed is aimed at partial or complete replacement of currently known protein feed components (such as soy meal, meat and bone meal and fish meal).&#x0D; In the course of the study, a trial production of a protein feed component was carried out, according to the methodologies described in the work, in order to test the proposed technology in practice.

Effects of partial replacement of fish meal with porcine meat meal on growth performance, antioxidant status, intestinal morphology, gut microflora and immune response of juvenile golden pompano (Trachinotus ovatus)

This study was conducted to investigate the effects of partial replacement of fish meal (FM) with porcine meat meal (PMM) on growth performance, plasma antioxidant parameters, intestine morphological parameters, gut microflora and expression of intestinal Nrf2 and Nf-κB signaling pathway of juvenile golden pompano. Fish were fed with six experimental diets (0 (PC), 10% (P10), 20% (P20), 30% (P30), 40% (P40) and 50% (P50) replacement levels) for 8-weeks. The percent weight gain and specific growth rate in fish fed with P40 and P50 diets were significantly lower than those of the control group (P < 0.05). Compared with the control group, the plasma antioxidant indexes including the activities of superoxide dismutase, catalase, glutathione peroxidase, total antioxidant capacity and malondialdehyde content in fish fed with P30, P40 and P50 diets were significantly affected (P < 0.05). With dietary replacement of FM with PMM increasing 0 to 30%, the relative expressions of IL-10, TGF-β, Nrf2, SOD, Cu/Zn-SOD and GSH-Px were significantly down-regulated, while the relative expressions of NF-κB, TNF-α, IL-1β and IL-8 were significantly up-regulated (P < 0.05). Villus heights and crypt depths of proximal and mid intestine were significantly affected with dietary replacement of FM with PMM increasing 0 to 40% (P < 0.05). The structure of the intestinal microbial flora showed that the relative abundances of beneficial bacteria decreased, and the relative abundances of pathogenic bacteria increased in fish fed with P50 diet compared with the control group. In conclusion, replacing FM with PMM up to 30% had no significant impact on growth performance and feed utilization of golden pompano. However, 30% replacements of FM with PMM exerted adverse effects on antioxidant capacity and immune response of fish. In addition, replacement of a high proportion of FM with PMM negatively affect the gut microflora of fish.

Fishmeal Replacement with Animal Protein Source (Crocodylus niloticus Meat Meal) in Diets of Mozambique Tilapia (Oreochromis mossambicus) of Different Size Groups

Fish are generally known to change their nutritional requirements depending on their life stage and formulating feeds for different size groups to meet their dietary needs is essential. This study aimed to assess the potential of Crocodylus niloticus meat meal as an animal protein source replacing fishmeal in Oreochromis mossambicus diets. Ten fry (0.07 g fish−1) were randomly assigned to three formulated diets (0% (D1), 50% (D2), and 100% (D3)), and each diet had three replicates. The fry were fed 10% body weight per day (BWd−1) for 30 days. New diets (0% (D4), 50% (D5), and 100% (D6)) were introduced, and the feeding rate was reduced to 5% BWd−1 for 48 days. After that, the fish were fed 2% BWd−1 for 78 days, the same diets used for fingerlings. All size groups were fed two portions of their daily ration at 10:30 h and 15:30 h. Our results point to the suggestion that Crocodylus niloticus meat meal may replace fishmeal for Oreochromis mossambicus, as there were no significant differences in weight gain (G), specific growth rates (SGR), gross feed conversion ratios (GFCR), or protein efficiency ratios (PER) for fry fed different diets. Furthermore, there were similarities in Gs, SGRs, GFCRs, and PER in fingerlings and sub adult to adult fish fed D4 and D5. The cost analysis of ingredients used in diets with 50% and 100% Crocodylus niloticus meat meal indicated that it was profitable to use this meat meal in diets of O. mossambicus of all groups. The profit index of 0.3 for fry, 0.8 for fingerlings, and 1.9 for subadults to adults for 100% fishmeal diets were lower than 0.4 and 0.5 for fry, 0.9 and 1.1 for fingerlings, and 2.3 and 2.9 for sub adult to adult fish fed diets with 50% and 100% crocodile meat meal, respectively.

CO2 adsorption on pyrolysis char from protein-containing livestock waste: How do proteins affect?

Biogas generation through anaerobic digestion provides an interesting opportunity to valorize some types of animal waste materials whose management is increasingly complicated by legal and environmental restrictions. To successfully expand anaerobic digestion in livestock areas, operational issues such as digestate management must be addressed in an economical and environmentally sustainable way. Biogas upgrading is another necessary stage before intending it to add-value applications. The high concentration of CO2 in biogas results in a reduced caloric value, so the removal of CO2 would be beneficial for most end-users. The current work evaluates the CO2 uptake properties (thermogravimetry study) of low-cost adsorbent materials produced from the animal wastes generated in the livestock area itself, specifically via pyrolysis of poorly biodegradable materials, such as meat and bone meal, and the digestate from manure anaerobic digestion. Therefore, the new element in this study with respect to other studies found in the literature related to biochar-based CO2 adsorption performance is the presence of high content of pyrolyzed proteins in the adsorbent material. In this work, pyrolyzed chars from both meat and bone meal and co-digested manure have been proven to adsorb CO2 reversibly, and also the chars produced from their representative pure proteins (collagen and soybean protein), which were evaluated as model compounds for a better understanding of the individual performance of proteins. The ultra-microporosity developed in the protein chars during pyrolysis seems to be the main explanation for such CO2 uptake capacities, while neither the BET surface area nor N-functionalities on the char surface can properly explain the observed results. Although the CO2 adsorption capacities of these pristine chars (6–41.0 mg CO2/g char) are far away from data of commercially activated carbons (~80 mg CO2/g char), this application opens a new via to integrate and valorize these wastes in the circular economy of the primary sector.

Fat Oxidation of Fatty Fish vs. Meat Meal Diets Under in vitro Standardized Semi-Dynamic Gastric Digestion.

Meat and fish are introduced into the diet as a source of protein, but these muscle foods present different fatty acid (FA) compositions and different lipid stabilities. Fatty fish is expected to oxidize due to its higher content of polyunsaturated FA (PUFA), whereas the higher heme-Fe content of red meat will also affect lipid stability. Combining other food ingredients within a meal also influences lipid oxidation, which will not stop after meals intake. This is due to the acidic environment of the stomach together with the presence of metallic ions, a process that is scarcely understood. The goal of this study was to evaluate the oxidation of fatty fish vs. meat meal diets under in vitro standardized semi-dynamic gastric conditions and FA release from the stomach to the duodenum. Meal diets composed by 25% beef meal (BM) or fatty fish meal (FM), 25% fried potatoes, and 50% sugar soft drink were prepared. Proximate composition, FA and amino acid profiles, and meals quality indices were evaluated. Their differences in composition led to different total gastric digestion time of 242.74 (BM) and 175.20 (FM) minutes. Using the INFOGEST semi-dynamic gastric model, 4 gastric emptying (GE) were simulated in both meals. In each GE, FA profile and lipid oxidation products (LOPs) formation were assessed. As a result, more than 50% FA release to the duodenum occurred in GE1, whose percentage decreased with the time of digestion. FM exhibited the highest LOPs formation, which corroborates the high peroxidizability index measured for this meal diet. Higher LOPs formation occurred in the later GEs, which released less FA. This suggests that higher times of residence in the stomach increase FA oxidation. This study shows a higher formation of LOPs during digestion of FM using a whole meal approach. These results relate to its richness in PUFAs compared to BM. Despite higher LOPs formation, FM digests that reached duodenum still contain higher content of unoxidized PUFAs compared with BM and a desirable ω3/ω6 PUFAs ratio of ~0.43. LOPs formation in PUFA-rich meals could be reduced if those meals have a low caloric value, avoiding large times of residence in the stomach and consequently high levels of oxidation.

PEMANFAATAN SOLID EX-DECANTER DALAM PEMBUATAN ROTI SOLID DENGAN TAMBAHAN ONGGOK SEBAGAI PAKAN TERNAK RUMINANSIA

Solid bread is ruminant feed made from solid ex-decanter that has gone through a mixing process with local ingredients and has been molded into a circle so that it looks like bread and is referred to as solid bread. This study uses experimental methods. Consists of 3 levels of treatment, namely: without fermentation, 7 days of fermentation, and 14 days of solid fermentation using EM-4. The addition of local ingredients, namely cassava (onggok), palm kernel meal, molasses, salt, and lime can help the nutritional content of solid bread to conform to the Indonesian National Standard (SNI). The parameters tested in this study were: crude protein (PK), crude fat (LK), crude fiber (SK), ash, calcium (Ca), phosphorus (P), and water. Unfermented solid bread contains 14.05% crude protein, 9.23% crude fat, 20.46% crude fiber, 5.10% ash, 0.8097% calcium, 0.744% phosphorus, 8.17% water. The 7-day fermented solid bread contains 22.79% crude protein, 8.04% crude fat, 12.27% crude fiber, 4.20% ash, 0.8931% calcium, 0.794% phosphorus, 8.98% water. Fermented solid bread for 14 days contains 28.20% crude protein, 7.87% crude fat, 9.32% crude fiber, 3.82% ash, 0.9378% calcium, 0.829% phosphorus, 9.56% water. The results of this study indicate that several treatments, namely non-fermented, fermented for 7 days, fermented for 14 days, and some of the nutritional content of solid bread have met SNI. Crude protein, crude fiber, ash, calcium, and water content meet SNI but some do not meet SNI such as crude fat, and phosphorus in 7-day fermentation and 14-day fermentation. In non-fermentation, phosphorus has met SNI.

Do carbon footprint labels promote climatarian diets? Evidence from a large-scale field experiment

We estimate the causal effect of carbon footprint labels on individual food choices and quantify potential carbon emission reductions, using data from a large-scale field experiment at five university cafeterias with over 80,000 individual meal choices. Results show that carbon footprint labels led to a decrease in the probability of selecting a high-carbon footprint meal by approximately 2.7 percentage points with consumers substituting to mid-carbon impact meals. We find no change in the market share of low-carbon meals, on average. The reduction in high-carbon footprint meals is driven by decreases in sales of meat meals while sales of mid-ranged vegan, vegetarian and fish meals all increased. We estimate that the introduction of carbon footprint labels was associated with a 4.3% reduction in average carbon emissions per meal. We contrast our findings with those from nudge-style interventions and discuss the cost-effectiveness of carbon footprint labels. Our results suggest that carbon footprint labels present a viable and low-cost policy tool to address information failure and harness climatarian preferences to encourage more sustainable food choices.
